Abstract
The prenylated flavonoid icaritin (ICT, 1), a new drug for treating advanced hepatocellular carcinoma (HCC), was selected as a template to develop more potent inhibitors. An initial semisynthetic modification of ICT was performed to obtain a structure-activity relationship (SAR), which indicated that the cytotoxicity is enhanced by OH-3 rhamnosylation and that OH-7 is an important modification site. Based on the results of the SAR study, 46 N-containing ICT derivatives were synthesized and evaluated as the anti-HCC inhibitors. The results showed that most of the derivatives produced inhibited three HCC cell lines used (Hep3B, HepG2 and SMMC-7721). The modification strategy was validated by 3D-QSAR, which provided information for the further design and optimization of ICT. The most potent compound, 11c, exhibited IC50 values of 7.6 and 3.1 μM against HepG2 and SMMC-7721 cells, respectively, which were more potent than those of ICT and sorafenib, respectively. Further mechanistic studies indicated that 11c caused arrest at the G0/G1 phase in the cell cycle and induced cell apoptosis in HepG2 and SMMC-7721 cells.

Abstract
To synthesize a water-soluble paclitaxel derivative, the anomers of diols of allyl 2,3,4-tri- O-benzyl-6- O-tritylglycoside (maltoside) were prepared, which can be separated by chromatographic procedure. One anomer was converted into α-glycosyloxyacetic acid (maltosyloxyacetic acid) by oxidative cleavage of the diol and subsequent oxidation. Ester-linked paclitaxel-glycoside conjugate, 7-glycolylpaclitaxel 2″- O-α-maltoside, was provided by condensation of 2′-TES paclitaxel with α-glycosyloxyacetic acid (maltosyloxyacetic acid) followed by deprotection of hydroxy groups.

Abstract
Prodrugs are biologically inactive drug molecules that may be developed through rational drug design with an objective to improve a drug's pharmaceutical and pharmacokinetic properties. Paclitaxel, a highly potent anticancer drug, is directed against many cancers like breast cancer, ovarian cancer, lung cancer, head and neck tumors, non-small cell lung cancer, and Kaposi's sarcoma, etc. Along with its excellent antitumor activity the drug had a major limitation of low water solubility. To overcome this limitation of this nanomolar active drug many prodrugs were formed in the past. Though increase in the solubility of the drug was obtained but that may or may not account for its increase in bioavailability. CYP3A4 liver enzymes are responsible for the metabolism of fifty percent of the drugs and are major metabolizing enzyme for paclitaxel. Phosphate prodrugs are well known to account the insolubility of many drugs and thus increasing their bioavailability also. In this study, we calculated the ADMET properties of a dataset of twenty phosphate prodrugs of paclitaxel. On the basis of reflection of three favourable properties, ten prodrugs were chosen for further docking studies against CYP3A4. Finally, three prodrugs showing unfavourable binding affinities were selected for Molecular Dynamics Simulations and from this in-silico study we identified that all the three selected prodrugs were unstable as compared to the paclitaxel. The instability of these prodrugs showed their lesser interaction with the CYP3A4 and hence contributing more towards its bioavailability. Thus the three suggested prodrugs those were studied in-silico for oral bioavailability can be further validated for gastrointestinal cancer.Communicated by Ramaswamy H. Sarma.

Abstract
In this paper, we report the preparation of paclitaxel-terminated peptide brush polymers wherein cell uptake and toxicity are tunable based on peptide sequence. Synthesis was enabled using a new paclitaxel-containing chain termination agent for ring-opening metathesis polymerization (ROMP). Critically, reverse phase HPLC could be used to efficiently separate peptide brush polymers consisting of one fluorophore and one terminal paclitaxel from crude polymer mixtures. These purified terminally-modified polymers showed greater potency than the original mixtures. Drug-terminated peptide brush polymers carrying positive charges exhibited enhanced cell uptake and cytotoxicity as compared to their neutral and negatively charged analogues.

Abstract
PURPOSE TXA9, a novel cardiac glycoside, has a potent anti-proliferative effect against A549 human lung cancer cells, however, possesses a poor water-solubility and a rapid metabolic rate in vivo which limited the further development of TXA9. To overcome the shortcomings of TXA9, four polymer prodrugs of TXA9 were designed and synthesized. METHODS Poly (ethylene glycol) monomethyl ether (mPEG) and α-tocopherol polyethylene glycol succinate (TPGS) were applied to modify TXA9 via carbonate ester and glycine linkers respectively to obtain four polymer prodrugs. The water-solubility and stability of prodrugs were studied in vitro while their pharmacokinetic behaviors and antitumor activity were investigated in vivo. RESULTS The water-solubility of TXA9 was obviously increased and prodrugs with glycine linkers showed a better stability in rat plasma. Their pharmacokinetic investigation found that the t1/2 and AUC0-∞ of TPGS-Gly-TXA9 was increased by 80- and 9.6-fold compared with that of TXA9, which was more superior than the other three prodrugs. More importantly, the tumor inhibition rate of TPGS-Gly-TXA9 (43.81%) on A549 xenograft nude mice was significantly increased compared with that of TXA9 (25.26%). CONCLUSION The above results suggested that TPGS-Gly-TXA9 possessed better antitumor efficiency than TXA9 and could be further investigated as an anti-cancer agent.

Abstract
A spectrophotometric technique has been applied for studying the reduction of chromium(VI) by poly(ethylene glycol) (PEG) as water-soluble and nontoxic synthetic polymer at a constant ionic strength of 4.0 mol dm-3 in the absence and presence of the ruthenium(III) catalyst. In the absence of the catalyst, the reaction orders in [Cr(VI)] and [PEG] were found to be unity and fractional first orders, respectively. The oxidation process was found to be acid-catalyzed with fractional second order in [H+]. The addition of Ru(III) was found to catalyze the oxidation rates with observation of zero-order reaction in [CrO4 2-] and fractional orders in both [PEG] and [Ru(III)], respectively. The PEG reduces the soluble toxic hexavalent Cr(VI) as a model pollutant to the insoluble nontoxic Cr(III) complex, which is known to be eco-friendly and more safer from the environmental points of view. The acid derivative of PEG was found to possess high affinity for the removal of poisonous heavy metal ions from contaminant matters by chelation. Formation of the 1:1 intermediate complex has been kinetically revealed. A consistent reaction mechanism of oxidation was postulated and discussed.

Abstract
Polymeric biomaterials and nanoparticles (NPs) have shown a potential to be widely used for medical purposes. Functional limits of their biocompatibility depend on cellular and molecular responses between host and their artificial surfaces. Accordingly, medical devices of polymer biomaterials like endovascular stents, cardiopulmonary bypass circuits, and prostheses, may trigger inflammation or can be rejected by host due to the induction of immune responses. Furthermore, the main restriction to the use of NPs for medical purposes is their short in vivo circulation time because of their rapid clearance via the reticuloendothelial system. Various methods are under investigation to produce bioinert biomaterials and NPs. Currently, PEGylation and camouflaging are the most common approaches to enhance their biocompatibility. However, the disadvantages and limitations of these methods are leading to research new strategies. The CD47 molecule is well known as a widely expressed cellular surface receptor activating the transudction of the ''don't-eat-me'' signal. This review elaborates on the role of CD47 in the immune system and the application of CD47 mimicry peptides to produce bioinert biomaterials and NPs.

Abstract
Polymeric micelles have attracted considerable attention for effective delivery of poorly water-soluble cancer drugs. Polyethylene glycol (PEG), which has been approved for human use by the US Food and Drug Administration, is the most commonly used hydrophilic component of polymeric micelles because it is biocompatible and biodegradable. One disadvantage of traditional polymeric micelles is that they include a large amount of inert carrier materials, which do not contribute to therapeutic activity but increase cost and toxicity risk. A better alternative may be "dual-functional" micellar carriers, in which the hydrophobic carrier material (conjugated to PEG) has intrinsic therapeutic activity that complements, or even synergizes with, the antitumor activity of the drug cargo. This review summarizes recent progress in the development of PEG-derivatized dual-functional nanomicelles and surveys the evidence of their feasibility and promise for cancer therapy.

Abstract
In this study, mesoporous SnO2 (MSn) with a three-dimensional mesoporous structure was prepared using MCM-48 as the template in order to increase the oral bioavailability and dissolution rate of insoluble drugs. The model drug, nitrendipine (NDP), was loaded into the MSn by the adsorption method. The structural features of MSn were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and N2 adsorption (desorption) analysis. NDP was existed in the pore channels of MSn in an amorphous state, which was characterized by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), and Fourier transform infrared spectroscopy (FTIR). MSn showed a good biocompatibility in the cell toxicity assay for Caco-2 cells. In vitro dissolution results suggested that MSn could significantly enhance the dissolution rate of NDP compared with commercial NDP tablets. Pharmacokinetic studies indicated that NDP-MSn tablets effectively enhanced the oral bioavailability of NDP. In conclusion, MSn was found to be a potential carrier for improving the solubility of insoluble drugs.

Abstract
This work aimed to achieve long-lasting delivery of radix ophiopogonis polysaccharide (ROP) by sucrose acetate isobutyrate (SAIB)-based in situ forming systems (ISFSs) alone or combined with mono-PEGylation of ROP. When the ‘90%SAIB/10% solvent’ system was used, the mean residence time (MRT) of ROP was prolonged by 4.3 5 ∼ 7.00 times and the initial release rate was reduced significantly. However, this system was only suitable for days-long sustained release of ROP in short-term therapy. As to the ‘SAIB/additives/solvent’ system containing mono-PEGylated ROP, the results indicated that SAIB/poly(d,l-lactide-co-glycolide) (PLGA)/N-methyl-2-pyrrolidone (NMP) was superior to SAIB/polylactic acid (PLA)/NMP and SAIB/PLA/ethanol in controlled release. Moreover, weeks- to months-long (16–60 d) smooth release of ROP could be achieved by varying the concentration (10–30%) and molecular weight (MW) of PLGA (10–50 kDa) or by employing a moderate MW of PEGylated ROP (∼20 or ∼30 kDa). With further increasing the conjugate MW to ∼40 kDa, the contribution of drug elimination to its plasma retention seemed to surpass that of the SAIB-based system, resulting in that the system no longer had an obvious influence on the in vivo behavior of the conjugate. Besides, the results of host response confirmed that with less solvent being used, the SAIB-based systems showed a higher biocompatibility than the PLGA-based systems, suggesting that they could be freely chosen in the prevention and/or cure of chronic diseases.

Abstract
Synthesis of ester-linked oligosaccharide conjugate of taxol, i.e., 7-glycolyltaxol 2″- O-α-maltotrioside, was investigated by enzymatic procedure. The starting material, 7-glycolyltaxol 2″- O-α-D-glucoside, was glycosylated by cyclodextrin glucanotransferase to 7-glycolyltaxol 2″- O-α-maltooligosides [α-maltooligosaccharides; α-Glc-1→(4-α-Glc-1→)n-14-α-glucosides (n = 1–4)]. The enzymatic hydrolysis of 7-glycolyltaxol 2″- O-α-maltooligosides gave 7-glycolyltaxol 2″- O-α-maltotrioside. Both bio-nanocapsules and hybrid-bio-nanocapsules containing 7-glycolyltaxol 2″- O-α-maltotrioside exhibited high in vitro anti-tumor activities.

Abstract
Incorporating labile bonds inside polymer backbone and side chains yields interesting polymer materials that are responsive to change of environmental stimuli. Drugs can be conjugated to various polymers through different conjugation linkages and spacers. One of the key factors influencing the release profile of conjugated drugs is the hydrolytic stability of the conjugated linkage. Generally, the hydrolysis of acid-labile linkages, including acetal, imine, hydrazone, and to some extent β-thiopropionate, are relatively fast and the conjugated drug can be completely released in the range of several hours to a few days. The cleavage of ester linkages are usually slow, which is beneficial for continuous and prolonged release. Another key structural factor is the water solubility of polymer-drug conjugates. Generally, the release rate from highly water-soluble prodrugs is fast. In prodrugs with large hydrophobic segments, the hydrophobic drugs are usually located in the hydrophobic core of micelles and nanoparticles, which limits the access to the water, hence lowering significantly the hydrolysis rate. Finally, self-immolative polymers are also an intriguing new class of materials. New synthetic pathways are needed to overcome the fact that much of the small molecules produced upon degradation are not active molecules useful for biomedical applications.

Abstract
Over several decades, natural polysaccharides (PSs) have been actively exploited for their wide bioactivities. So far, many PS-related reviews have been published; however, none focused on the delivery of bioactive PSs as therapeutic molecules. Herein, we summarized and discussed general pharmacokinetic properties of PSs and drug delivery systems (DDSs) developed for them, together with the challenges and prospects. Overall, most bioactive PSs suffer from undesirable pharmacokinetic attributes, which negatively affect their efficacy and clinical use. Various DDSs therefore have been being utilized to improve the drug-like properties and curative efficacy of bioactive PSs by means of improving oral absorption, controlling the release, enhancing the in vivo retention ability, targeting the delivery, exerting synergistic effects, and so on. Specifically, nano-sized insoluble DDSs were mainly applied to improve the oral absorption and target delivery of PSs, among which liposome was especially suitable for immunoregulatory and/or anti-ischemic PSs due to its synergistic effects in immunoregulation and biomembrane repair. Chemical conjugation of PSs was mainly utilized to improve their oral absorption and/or prolong their blood residence. With formulation flexibility, in situ forming systems alone or in combination with drug conjugation could be used to achieve day(s)- or month(s)-long sustained delivery of PSs per dosing.

He R, Yin C. Trimethyl chitosan based conjugates for oral and intravenous delivery of paclitaxel. Acta Biomater 2017; 53:355-366.

Abstract
Paclitaxel (PTX) conjugated trimethyl chitosan (TMC-PTX) and folic acid (FA) modified TMC-PTX (FA-TMC-PTX) were developed as polymer-drug conjugates for oral and intravenous delivery of PTX. As amphiphilic conjugates, TMC-PTX and FA-TMC-PTX containing approximately 11wt% PTX could self-assemble into spherical nanoparticles with average sizes of 170 and 187nm, respectively. The conjugates presented a sustained release of PTX and the release rate was positively correlated with the pH value of medium ranging from 1.2 to 7.4. TMC-PTX and FA-TMC-PTX possessed enhanced mucoadhesion compared with trimethyl chitosan, and promoted ex vivo intestinal transport of PTX in comparison to PTX solution by 15.5 and 18.8 folds, respectively. Hemolysis assessment confirmed the safety of TMC-PTX and FA-TMC-PTX, and FA modification alleviated protein adsorption of the conjugates. Prolonged blood retention and increased PTX accumulation in the tumor were achieved for orally and intravenously administered conjugates. In H22 tumor-bearing mice, TMC-PTX delivered via oral or intravenous route showed superior tumor retardation and survival rate compared with intravenously injected PTX, and FA-TMC-PTX further enhanced the antitumor efficacy. Overall, the trimethyl chitosan based drug conjugates may have potential applications as a promising candidate for cancer therapy. STATEMENT OF SIGNIFICANCE In the current study, PTX conjugated trimethyl chitosan (TMC-PTX) and folic acid (FA) modified TMC-PTX (FA-TMC-PTX) were developed as the polymer-drug conjugates for oral and intravenous delivery of PTX. By exploiting advantages with respect to improved solubility of drugs, controlled release behavior of covalently linked drugs, and enhanced targeting effect towards tumors, improved tumor growth inhibition efficacy and prolonged survival time were achieved for TMC-PTX as compared with free PTX, and FA modification further enhanced the in vivo antitumor efficacy. Overall, the self-assembled nanoplatform of trimethyl chitosan based drug conjugates may have potential applications as a promising candidate for tumor therapy via different administration routes.

Abstract
3FDT, an analog of docetaxel with a blocked metabolism at its 3'-N-tert-butyloxyl group with three fluorine atoms, exhibits more potent cytotoxicity than docetaxel both with human cancer cell line SK-OV-3 in vitro and with human non-small cell lung cancer A549 xenografts in vivo. To further develop pharmacodynamically and pharmacokinetically favorable fluorinated docetaxel analogs as anticancer agents, we chose 3FDT as the model compound to identify the metabolites of 3FDT in RLMs, rats, and HLMs and the cytochrome P450 enzymes responsible for the metabolism of 3FDT. Our findings indicated that the major metabolic site switched from the C3' appendage for docetaxel to the taxane ring for 3FDT, and the main metabolizing P450 enzymes switched from CYP3A to CYP3A4 and CYP2E1.

Abstract
Three well known anticancer drugs, doxorubicin, methotrexate and paclitaxel (taxol), have been modified by the permanent attachment of poly(ethylene glycol)(PEG) and evaluated for in vitro cytotoxic activity against murine leukemias P388 and L1210. The relative potencies of the PEG derivatives suggest that modification of antitumor agents with this type of polymer yields compounds that are highly water soluble but less cytotoxic.

Abstract
Hydrophobized polyelectrolytes are able to aggregate in aqueous media and to form lipophilic microdomains which are much more stable than micelles made of amphiphilic diblock copolymers. Solubilization of paclitaxel in water by molecular encapsulation was attempted in the hydrophobic pockets present in the aggregates of hydrophobized poly(l-lysine citramide imide) polymers, PLCAixRy, where x = percentage in imide groups and y = percentage in alkyl substituents per lysine citramide repeat unit. A comparison was made of the physical entrapment and the solubilization of paclitaxel in PLCAi27C1234, PLCAC1275, PLCAi13C730, PLCAC12100 aggregates and in the usual allergic Cremophor® present in the Taxol® commercial formulation. PLCAixRy polymers solubilized paclitaxel in the selected aqueous medium proportionally to the polymer concentration. For comparable amounts in weight, the polymers were two to six times less efficient than Cremophor® in terms of equivalent mass of solubilizing species. A comparison between PLCAi13C730 and PLCAixC12y polymers suggested that dodecyl hydrophobizing groups were more efficient than heptyl ones in promoting the physical entrapment of paclitaxel. The antitumoral activity of the polymer-solubilized paclitaxel was tested in vitro against an ovarian carcinoma cell line (A2780). The C12 systems showed cytotoxicity, the IC50 values were statistically comparable in the 6.5-10.5 μg/L range. However, the amounts of drug incorporated in the polymer aggregates at the tested concentrations were still too low for clinical use. Improvements are expected from PLCA polymers with longer alkyl chains, greater hydrophobicity and higher concentrations.

Abstract
INTRODUCTION Most anticancer drugs have poor aqueous solubility and low permeability across the gastrointestinal tract. Furthermore, extensive efflux by P-glycoproteins (P-gp) in the small intestine also limits the efficient delivery of anticancer drugs via oral route. Area covered: This review explores the prodrug strategy for oral delivery of anticancer drugs. Different categories of oral anticancer prodrugs along with recent clinical studies have been comprehensively reviewed here. Furthermore, novel anticancer prodrugs such as polymer-prodrugs and lipid-prodrugs have been discussed in detail. Finally, various nanocarrier-based approaches employed for oral delivery of anticancer prodrugs have also been discussed. Expert opinion: Premature degradation of anticancer prodrugs in the gastrointestinal tract could lead to variable pharmacokinetics and undesired toxicity. Despite their increased aqueous solubility, the oral bioavailability of several anticancer prodrugs are limited by their poor permeability across the gastrointestinal tract. These limitations can be overcome by the use of functional excipients (polymers, lipids, amino acids/dipeptides), which are specifically absorbed via transporters and receptor-mediated endocytosis. Oral delivery of anticancer prodrugs using nanocarrier-based drug delivery system is a recent development; however it should be justified based on the comparative advantages of encapsulating prodrug in a nanocarrier versus the use of anticancer prodrug molecule itself.

Abstract
The use of nanotechnologies for biomedical applications took a real development during these last years. To allow an effective targeting for biomedical imaging applications, the adsorption of plasmatic proteins on the surface of nanoparticles must be prevented to reduce the hepatic capture and increase the plasmatic time life. In biologic media, metal oxide nanoparticles are not stable and must be coated by biocompatible organic ligands. The use of phosphonate ligands to modify the nanoparticle surface drew a lot of attention in the last years for the design of highly functional hybrid materials. Here, we report a methodology to synthesize bisphosphonates having functionalized PEG side chains with different lengths. The key step is a procedure developed in our laboratory to introduce the bisphosphonate from acyl chloride and tris(trimethylsilyl)phosphite in one step.

Abstract
Objectives. To review the pharmacokinetics and pharmacodynamics of docetaxel and paclitaxel. Data Sources. We reviewed the literature through a MEDLINE search from 1982 to 1996. The terms docetaxel, paclitaxel, taxanes, and taxoids were used in the search. Relevant articles cited in literature obtained by MEDLINE searching, as well as new articles published in early 1997 in specific oncology journals, were also considered. Data Extraction. We have reviewed the current literature with regard to the chemistry, mechanisms of action and pharmacology, pharmacokinetics, clini cal use, adverse effects, drug interactions, formula tion, dosage, administration, and pharmaceutical is sues of the taxanes. Conclusion. Both docetaxel and paclitaxel are novel antineoplastic agents with significant activity in many types of cancer. The pharmacokinetics of both agents are best characterized by a three-compartment disposition profile. However, the pharmacokinetics of paclitaxel, not docetaxel, are non-linear and can be described by a saturation process in distribution and elimination. The nonlinearity appears to be associated more frequently with shorter infusions and/or higher doses. There is evidence suggesting that the time duration of paclitaxel concentrations maintained above 0.1 μM/L (T>0.1 μM ) is associated with improved survival and development of toxicity. On the other hand, currently there is no information relating opti mal systemic exposure of docetaxel to efficacy and toxicity. In addition, these pharmacokinetic-pharma codynamic relationship may change with therapy with antineoplastic agents and other agents adminis tered concurrently, and necessitates additional phar macokinetic-pharmacodynamic investigations.

Abstract
Paclitaxel is an anti-tumor agent with remarkable anti-tumor activity and wide clinical uses. However, it is also faced with various challenges especially for its poor water solubility and low selectivity for the target. To overcome these disadvantages of paclitaxel, approaches using small molecule modifications and macromolecule modifications have been developed by many research groups from all over the world. In this review, we discuss the different strategies especially prodrug strategies that are currently used to make paclitaxel more effective.

Abstract
Melanoma originated from melanocytes is the most aggressive type of skin cancer with limited treatment options. New targeted therapeutic options with the discovery of BRAF and MEK inhibitors have shown significant survival benefits. Despite the recent progress, development of chemoresistance and systemic toxicity remains a challenge for treating metastatic melanoma. While the response from the first line of treatment against melanoma using dacarbazine remains only 5-10%, the prolonged use of targeted therapy against mutated oncogene BRAF develops chemoresistance. In this review, we will discuss the nanoparticle-based strategies for encapsulation and conjugation of drugs to the polymer for maximizing their tumor distribution through enhanced permeability and retention effect. We will also highlight photodynamic therapy and design of melanoma-targeted nanoparticles.

Abstract
A prodrug-based nanosystem obtained by formulating prodrug and nanotechnology into a system is one of the most promising strategies to enhance drug delivery for disease treatment. Herein, we report a new nanosystem based on HA-PTX conjugates (HA-PTX Ns), which penetrated across cell membranes into cytosol, thus enhancing paclitaxel (PTX) delivery. HA-PTX Ns were successfully obtained based on HA-PTX, and their average particle size was approximately 200 nm. Importantly, unlike other prodrug-based nanosystems, HA-PTX Ns obtained cellular entry without entrapment within the lysosomal-endosomal system by using pathways including clathrin-mediated endocytosis, microtubule-associated internalization, macropinocytosis and cholesterol-dependence. Due to significant accumulation in tumors, HA-PTX Ns had more than a 4-fold decrease in tumor volume on day 14 in contrast with PTX alone. In conclusion, HA-PTX Ns could enter cells, bypass the lysosomal-endosomal system and improve PTX delivery.

Abstract
Resveratrol is naturally occurring phytochemical with diverse biological activities such as chemoprevention, anti-inflammatory, anti-cancer, anti-oxidant. But undergoes rapid metabolism in the body (half life 0.13h). Hence Polymer conjugation utilizing different chemical linkers and polymer compositions was investigated for enhanced pharmacokinetic profile of resveratrol. Ester conjugates such as α-methoxy-ω-carboxylic acid poly(ethylene glycol) succinylamide resveratrol (MeO-PEGN-Succ-RSV) (2 and 20 kDa); MeO-PEG succinyl ester resveratrol (MeO-PEGO-Succ-RSV) (2 kDa); α-methoxy poly(ethylene glycol)-co-polylactide succinyl ester resveratrol (MeO-PEG-PLAO-Succ-RSV) (2 and 6.6kDa) were prepared by carbodiimide coupling reactions. Resveratrol-PEG ethers (2 and 5 kDa) were synthesized by alkali-mediated etherification. All polymer conjugates were fully characterized in vitro and the pharmacokinetic profile of selected conjugates was characterized in rats. Buffer and plasma stability of conjugates was dependent on polymer hydrophobicity, aggregation behavior and PEG corona, with MeO-PEG-PLAO-Succ-RSV (2 kDa) showing a 3h half-life in rat plasma in vitro. Polymer conjugates irrespective of linker chemistry protected resveratrol against metabolism in vitro. MeO-PEG-PLAO-Succ-RSV (2 kDa), Resveratrol-PEG ether (2 and 5 kDa) displayed improved pharmacokinetic profiles with significantly higher plasma area under curve (AUC), slower clearance and smaller volume of distribution, compared to resveratrol.

Abstract
Although PEGylation plays an important role in drug delivery, knowledge about the distribution behavior of PEGylated drugs in ischemic myocardia is rather limited compared to nanoparticles. This work therefore aims to characterize the targeting behavior of the anti-myocardial ischemic mono-PEGylated conjugates of Radix Ophiopogonis polysaccharide (ROP) in two clinically relevant animal models, ie, the myocardial infarction (MI) model and the ischemia/reperfusion (IR) model. To determine the effect of the molecular size of conjugates, two representative conjugates (20- and 40-kDa polyethylene glycol mono-modified ROPs), with hydrodynamic size being approximately and somewhat beyond 10 nm, respectively, were studied in parallel at three time points postdose after a method for determining them quantitatively in biosamples was established. The results showed that the cardiac distribution of the two conjugates was significantly enhanced in both MI and IR rats due to the enhanced permeability and retention effect induced by ischemia. In general, the cardiac targeting efficacy of the conjugates in MI and IR rats was approximately 2; however, different changing in targeting efficacy with time was observed between MI and IR rats and also between the conjugates. Although the enhanced permeability and retention effect-based targeting efficacy for mono-PEGylated ROPs was not high, they, as dissolved macromolecules, are prone to diffusion in the cardiac interstitium space, and thus, facilitate the drug to reach perfusion-deficient and nonperfused areas. These findings are helpful in choosing the cardiac targeting strategy.

Abstract
PURPOSE Macromolecular prodrugs obtained by covalently conjugating small molecular drugs with polymeric carriers were proven to accomplish controlled and sustained release of the therapeutic agents in vitro and in vivo. Polyethylene glycol (PEG) has been extensively used due to its low toxicity, low immunogenicity and high biocompatibility. However, for linear PEG macromolecules, the number of available hydroxyl groups for drug coupling does not change with the length of polymeric chain, which limits the application of PEG for drug conjugation purposes. To increase the drug loading and prolong the retention time of 5-fluorouracil (5-Fu), a macromolecular prodrug of 5-Fu, 5-fluorouracil-1 acid-PAE derivative (5-FA-PAE) was synthesized and tested for the antitumor activity in vivo. METHODS PEG with a molecular weight of 38 kDa was selected to synthesize the multi-hydroxyl polyethylene glycol derivative (PAE) through an addition reaction. 5-fluorouracil-1 acetic acid (5-FA), a 5-Fu derivative was coupled with PEG derivatives via ester bond to form a macromolecular prodrug, 5-FA-PAE. The in vitro drug release, pharmacokinetics, in vivo distribution and antitumor effect of the prodrug were investigated, respectively. RESULTS The PEG-based prodrug obtained in this study possessed an exceedingly high 5-FA loading efficiency of 10.58%, much higher than the maximum drug loading efficiency of unmodified PEG with the same molecular weight, which was 0.98% theoretically. Furthermore, 5-FA-PAE exhibited suitable sustained release in tumors. CONCLUSION This study provides a new approach for the development of the delivery to tumors of anticancer agents with PEG derivatives.

Abstract
Polymer hydrogels have been widely explored as therapeutic delivery matrices because of their ability to present sustained, localized and controlled release of bioactive factors. Bioactive factor delivery from injectable biopolymer hydrogels provides a versatile approach to treat a wide variety of diseases, to direct cell function and to enhance tissue regeneration. The innovative development and modification of both natural-(e.g., alginate (ALG), chitosan, hyaluronic acid (HA), gelatin, heparin (HEP), etc.) and synthetic-(e.g., polyesters, polyethyleneimine (PEI), etc.) based polymers has resulted in a variety of approaches to design drug delivery hydrogel systems from which loaded therapeutics are released. This review presents the state-of-the-art in a wide range of hydrogels that are formed though self-assembly of polymers and peptides, chemical crosslinking, ionic crosslinking and biomolecule recognition. Hydrogel design for bioactive factor delivery is the focus of the first section. The second section then thoroughly discusses release strategies of payloads from hydrogels for therapeutic medicine, such as physical incorporation, covalent tethering, affinity interactions, on demand release and/or use of hybrid polymer scaffolds, with an emphasis on the last 5 years.

Abstract
Previously, PEGylated paclitaxel (PEG-PTX) was found not favorable as a polymer prodrug because of its poor antitumor efficiency. But surprisingly, it was found in our study that PEG-PTX could form a novel nanoparticle system with free PTX. To address how this system works, we compared PTX loaded PEG-PTX nanoparticles (PEG-PTX/PTX) with PTX loaded PEG-PLA micelles (PEG-PLA/PTX) or PTX injection available (Taxol(®)) in vitro and in vivo. Firstly, it was found that PEG-PTX/PTX was more stable in aqueous solution than PEG-PLA/PTX in terms of PTX crystal formation and drug release. Then it was demonstrated that coumarin loaded PEG-PTX nanoparticles had a much higher uptake in MCF-7 cells compared to coumarin loaded PEG-PLA micelles. The in vivo imaging study revealed that DIR or DID (near infrared fluorescent substances) loaded PEG-PTX nanoparticles distributed more in tumors in MCF-7 tumor bearing mice than DIR or DID loaded PEG-PLA micelles and solvent system of Taxol(®). In the efficacy study with MCF-7 tumor bearing mice, PEG-PTX/PTX showed significantly higher antitumor activity than PEG-PLA/PTX at the same PTX dosage. At the dose of 10mg free PTX per kg, PEG-PTX/PTX displayed similar efficacy as Taxol(®) but less toxicity evaluated by the loss of body weight. With the increase of free PTX to 15 mg/kg, PEG-PTX/PTX showed significantly better efficacy than Taxol(®). In conclusion, with favorable characteristics in stability, cellular uptake, cytotoxicity, biodistribution, safety and efficacy, PEG-PTX/PTX seems highly potential as a nanocarrier for PTX delivery.

Abstract
With the objective to formulate multifunctional nanosized liposomes to target amyloid deposits in Alzheimer Disease (AD) brains, a lipid-PEG-curcumin derivative was synthesized and characterized. Multifunctional liposomes incorporating the curcumin derivative and additionally decorated with a Blood Brain Barrier (BBB) transport mediator (anti-Transferin antibody) were prepared and characterized. The fluorescence intensity of curcumin derivative was found to increase notably when the curcumin moiety was in the form of a diisopropylethylamine (DIPEA) salt. Both curcumin-derivative liposomes and curcumin-derivative Anti-TrF liposomes showed a high affinity for the amyloid deposits, on post-mortem brains samples of AD patients. The ability of both liposomes to delay Aβ1-42 peptide aggregation was confirmed by Thioflavin assay. However, the decoration of the curcumin-derivative liposomes with the Anti-TrF improved significantly the intake by the BBB cellular model. Results verify that the attachment of an antibody on the curcumin-liposome surface does not block deposit staining or prevention of Aβ aggregation, while the presence of the curcumin-PEG-lipid conjugate does not reduce their brain-targeting capability substantially, proving the potential of such multifunctional NLs for application in Alzheimer disease treatment and diagnosis.

Abstract
There has been an increasing interest to develop new types of stimuli-responsive drug delivery vehicles with high drug loading and controlled release properties for chemotherapeutics. An acid-labile poly(ethylene oxide)-block-polyphosphoester-graft-PTX drug conjugate (PEO-b-PPE-g-PTX G2) degradable, polymeric paclitaxel (PTX) conjugate containing ultra-high levels of PTX loading is improved significantly, in this second-generation development, which involves connection of each PTX molecule to the polymer backbone via a pH-sensitive β-thiopropionate linkage. The PEO-b-PPE-g-PTX G2 forms well-defined nanoparticles in an aqueous solution, by direct dissolution into water, with a number-averaged hydrodynamic diameter of 114 ± 31 nm, and exhibits a PTX loading capacity as high as 53 wt%, with a maximum PTX concentration of 0.68 mg mL(-1) in water (vs 1.7 μg mL(-1) for free PTX). The PEO-b-PPE-g-PTX G2 shows accelerated drug release under acidic conditions (≈50 wt% PTX released in 8 d) compared with neutral conditions (≈20 wt% PTX released in 8 d). Compared to previously reported polyphosphoester-based PTX drug conjugates, PEO-b-PPE-g-PTX G1 without the β-thiopropionate linker, the PEO-b-PPE-g-PTX G2 shows pH-triggered drug release property and 5- to 8-fold enhanced in vitro cytotoxicity against two cancer cell lines.

Abstract
Drug discovery and development has become longer and costlier process. The fear of failure and stringent regulatory review process is driving pharmaceutical companies towards “me too” drugs and improved generics (505(b) (2)) fillings. The discontinuance of molecules at late stage clinical trials is common these years. The molecules are withdrawn at various stages of discovery and development process for reasons such as poor ADME properties, lack of efficacy and safety reasons. Hence this review focuses on possible applications of formulation and drug delivery to salvage molecules and improve the drugability. The formulation and drug delivery technologies are suitable for addressing various issues contributing to attrition are discussed in detail.

Abstract
Polymersome vesicles and wormlike filomicelles self-assembled with amphiphilic, degradable block copolymers have recently shown promise in application to cancer therapy. In the case of filomicelles, dense, hydrophilic brushes of poly(ethylene glycol) on these nanoparticles combine with flexibility to nonspecifically delay clearance by phagocytes in vivo, which has motivated the development of "self" peptides that inhibit nanoparticle clearance through specific interactions. Delayed clearance, as well as robustness of polymer assemblies, opens the dosage window for delivery of increased drug loads in the polymer assemblies and increased tumor accumulation of drug(s). Antibody-targeting and combination therapies, such as with radiotherapy, are emerging in preclinical animal models of cancer. Such efforts are expected to combine with further advances in polymer composition, structure, and protein/peptide functionalization to further enhance transport through the circulation and permeation into disease sites.

Abstract
A new paclitaxel (Ptx) prodrug was designed by coupling a single terpene unit (MIP) to the hydroxyl group in position 2' of the drug molecule. Using a squalene derivative of polyethylene glycol (SQ-PEG) as surface active agent, the resulting bioconjugate (PtxMIP) self-assembled in water leading to the formation of stable nanoparticles (PtxMIP_SQ-PEG NPs) with an impressively high drug loading (82%). In vivo, the anticancer activity of this novel Ptx nanoassembled prodrug was compared to the conventional Cremophor-containing formulation (Taxol) on a murine model of breast cancer lung metastasis induced by intravenous injection of 4T1 tumor cells, genetically modified to stably express firefly luciferase. Cell growth was assessed noninvasively by bioluminescence imaging (BLI) which enabled monitoring tumor metastatic burden in the same animals. PtxMIP_SQ-PEG nanoparticles slowed metastatic spread and were better tolerated than the Cremophor-containing formulation (i.e., free drug), thus demonstrating the potential of terpene-based nanoassembled prodrugs in the improvement of the therapeutic index of Ptx in balb/c mice.
