[PMID: 38553209 DOI: 10.1016/j.carbpol.2024.121989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 02/09/2024] [Accepted: 02/24/2024] [Indexed: 04/02/2024]
Abstract
A novel delivery system comprising N-succinic anhydride (N-SAA) and D-fructose co-conjugated chitosan (NSCF)-modified polymeric liposomes (NSCF-PLip) were designed to enhance oral delivery of paclitaxel (PTX) by targeting monocarboxylate transporters (MCT) and glucose transporters (GLUT). The synthesized NSCF was characterised by FT-IR and 1H NMR spectra. The prepared 30.78 % (degree of substitution of N-SAA) NSCF-PTX-PLip were approximately 150 nm in size, with a regular spherical shape, the zeta potential of -25.4 ± 5.13 mv, drug loading of 2.35 % ± 0.05 %, and pH-sensitive and slow-release characteristics. Compared with PTX-Lip, 30.78 % NSCF-PTX-PLip significantly enhanced Caco-2 cellular uptake via co-mediation of MCT and GLUT, showing relatively specific binding of propionic acid and MCT. Notably, the NSCF modification of PTX-Lip had no appreciable influence on their original cellular uptake pathway. The fructose modification of 30.78 % NSC-PTX-PLip significantly increased the concentration after tmax, indicating their continuous and efficient absorption. Compared with PTX-Lip, the 30.78 % NSCF-PTX-PLip resulted in a 2.09-fold extension of MRT, and a 6.06-fold increase of oral bioavailability. It significantly increased tumour drug distribution and tumour growth inhibition rate. These findings confirm that 30.78 % NSCF-PLip offer a potential oral delivery platform for PTX and targeting the dual transporters of MCT and GLUT is an effective strategy for enhancing the intestinal absorption of drugs.

A Novel 2-Methoxyestradiol Derivative: Disrupting Mitosis Inhibiting Cell Motility and Inducing Apoptosis in HeLa Cells In Vitro. Pharmaceutics 2024; 16:622. [PMID: 38794284 PMCID: PMC11125453 DOI: 10.3390/pharmaceutics16050622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2024] [Revised: 04/30/2024] [Accepted: 05/01/2024] [Indexed: 05/26/2024] Open
Abstract
The clinical application of 2-methoxyestradiol (2ME) in cancer therapy has been limited by its low solubility and rapid metabolism. Derivatives of 2ME have been synthesised to enhance bioavailability and decrease hepatic metabolism. Compound 4a, an analog of 2ME, has demonstrated exceptional pharmacological activity, in addition to promising pharmacokinetic profile. Our study, therefore, aimed at exploring the anticancer effects of 4a on the cervical cancer cell line, HeLa. Compound 4a exhibited a significant and dose-dependent antimetastatic and antiinvasive impact on HeLa cells, as determined by wound-healing and Boyden chamber assays, respectively. Hoechst/Propidium iodide (HOPI) double staining showcased a substantial induction of apoptosis via 4a, with minimal necrotic effect. Flow cytometry revealed a significant G2/M phase arrest, accompanied by a noteworthy rise in the sub-G1 cell population, indicating apoptosis, 18 h post-treatment. Moreover, a cell-independent tubulin polymerisation assay illustrated compound 4a's ability to stabilise microtubules by promoting tubulin polymerisation. Molecular modelling experiments depicted that 4a interacts with the colchicine-binding site, nestled between the α and β tubulin dimers. Furthermore, 4a displayed an affinity for binding to and activating ER-α, as demonstrated by the luciferase reporter assay. These findings underscore the potential of 4a in inhibiting HPV18+ cervical cancer proliferation and cellular motility.

Abstract
Hydrogel-based drug delivery systems (DDSs) can leverage therapeutically beneficial outcomes in cancer therapy. In this domain, polyethylene glycol (PEG) has become increasingly popular as a biomedical polymer and has found clinical use. Owing to their excellent biocompatibility, facile modifiability, and high drug encapsulation rate, PEG hydrogels have shown great promise as drug delivery platforms. Here, the progress in emerging novel designs of PEG-hydrogels as DDSs for anti-cancer therapy is reviewed and discussed, focusing on underpinning multiscale release mechanisms categorized under stimuli-responsive and non-responsive drug release. The responsive drug delivery approaches are discussed, and the underpinning release mechanisms are elucidated, covering the systems functioning based on either exogenous stimuli-response, such as photo- and magnetic-sensitive PEG hydrogels, or endogenous stimuli-response, such as enzyme-, pH-, reduction-, and temperature-sensitive PEG hydrogels. Special attention is paid to the commercial potential of PEG-based hydrogels in cancer therapy, highlighting the limitations that need to be addressed in future research for their clinical translation.

Tang J, Liu C, Liu S, Zhou X, Lu J, Li M, Zhu L. Inhibition of JAK1/STAT3 pathway by 2-methoxyestradiol ameliorates psoriatic features in vitro and in an imiquimod-induced psoriasis-like mouse model. Eur J Pharmacol 2022; 933:175276. [PMID: 36130639 DOI: 10.1016/j.ejphar.2022.175276] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 09/07/2022] [Accepted: 09/08/2022] [Indexed: 11/03/2022]
Abstract
Psoriasis is characterized by hyperproliferative keratinocytes, dilated capillaries and leukocyte infiltration. 2-Methoxyestradiol (2-ME) has shown significant inhibition on proliferation, angiogenesis and inflammation. To evaluate the anti-psoriatic potential of 2-ME, psoriasis-like dermatitis was induced by topical application of imiquimod (IMQ) on the dorsal skin of C57BL/6 mice for seven consecutive days, followed by treatment of vehicle or 2-ME ointment from Day 4 on. The psoriasis area and severity index (PASI) was assessed daily. On Day 8, skin histology and spleen index were assessed. The effects of 2-ME on the proliferation, apoptosis, cell cycle, vascular endothelial growth factor A (VEGFA), and Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathways of HaCaT cells stimulated by interleukin-17 (IL-17A) were detected, together with its effect on the proliferation, tube formation and VEGF receptor expression of human umbilical vein endothelial cells (HUVECs). We found that topical 2-ME treatment significantly improved IMQ-induced psoriasis-like dermatitis and decreased the PASI scores, the activation of STAT3 in the skin (P < 0.05), and the spleen index in mice (P < 0.01). In vitro, 2-ME inhibited the proliferation of HaCaT cells by inducing apoptosis and G2/M phase arrest (P < 0.01). Moreover, 2-ME suppressed IL-17A-induced VEGFA (2.5 μM: P < 0.05; 5 μM: P < 0.01) and phosphorylation of STAT3 by blocking p-JAK1 in HaCaT cells and prevented tube formation (P < 0.01) and proliferation by targeting VEGF receptors 1 (VEGFR1) and 2 (VEGFR2) in HUVECs. We conclude that 2-ME alleviated psoriasis in vivo and in vitro by inhibiting JAK1/STAT3 pathway and was a promising therapeutic agent for psoriasis.

Abstract
Based on glucose (G) transporters (GLUTs), structuring nanoparticles with G as a target are an effective strategy to enhance oral bioavailability and anti-tumor effects of drugs. A novel drug delivery system using G-modified zein (GZ) nanoparticles loaded with docetaxel (DTX) (DTX-GNPs) was prepared and characterized in vitro and in vivo via assessment of cellular uptake, absorption site, pharmacokinetics, ex vivo distribution, and anti-tumor effects. The DTX-GNPs were approximately 120 nm in size. Compared with DTX-NPs, G modification significantly enhanced cellular uptake of DTX-GNPs by 1.22 times in CaCo-2 cells, which was related to GLUT mediation and the enhancement of endocytosis pathways via clathrin, micropinocytosis, and caveolin. Compared to DTX-NPs, G modification significantly enhanced DTX-NP absorption in the jejunum and ileum, delayed plasma concentration peak time, prolonged the average residence time in vivo, and increased oral bioavailability (from 43.82% to 96.04%). Cellular uptake and oral bioavailability of DTX were significantly affected by the G modification ratio. Compared with DTX-NPs, G modification significantly reduced drug distribution in the liver, lungs, and kidneys and increased tumor distribution and tumor growth inhibition rate without obvious systemic toxicity. This study demonstrated the potential of GZ-NPs as nanocarriers for DTX to enhance oral bioavailability and anti-tumor effects.

Yu C, Li C, Pan H, Li T, He S. Preparation of 2-Methoxyestradiol Self-emulsified Drug Delivery System and the Effect on Combination Therapy with Doxorubicin Against MCF-7/ADM Cells. AAPS PharmSciTech 2022; 23:147. [PMID: 35585431 DOI: 10.1208/s12249-022-02298-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 05/03/2022] [Indexed: 12/18/2022] Open
Abstract
Due to the poor solubility and bioavailability of 2-methoxyestradiol (2-ME), 2-ME emulsified drug delivery system (2-ME-SEDDS) was designed and characterized. After dilution with 5% glucose, 2-ME-SEDDS formed fine emulsions with mean diameter of 171 ± 14 nm and zeta potential of - 7.4 ± 0.6 mV. The cytotoxicity of 2-ME-SEDDS against MCF-7 and MCF-7/ADM cells was considerable to that of free 2-ME, and the half maximal inhibitory concentration ran up to 195 µg/mL on MCF-7/ADM cells. In order to gain a satisfactory inhibition effect on MCF-7/ADM cells, 2-ME-SEDDS combined with doxorubicin was used. It is worth noting that the combination of 2-ME-SEDDS and doxorubicin displayed a superior synergistic effect with a combined index of 0.62. And the cellular uptake of doxorubicin by MCF-7/ADM cells in the combination group was significantly higher than that of doxorubicin treatment group. The study preliminarily suggested that 2-ME-SEDDS could increase the cellular uptake of doxorubicin by MCF-7/ADM cells and the synergistic effect may be attributed to the increased cellular uptake of doxorubicin under the influence of 2-ME-SEDDS. In conclusion, SEDDS was an alternative and promising formulation for 2-ME. The combination therapy with synergistic effect by the combination of 2-ME-SEDDS and doxorubicin seems to be a promising strategy to potentiate anti-tumor efficiency against MCF-7/ADM, even other multidrug resistance tumors.

Abstract
With the deepening of tumor targeting research, the application of intelligent responsive drug carriers in the field of controlled drug release has become more and more extensive, and multiple responsive nano drug carriers have attracted greater attention. In this paper, nanoparticles with gold nanorods (GNR) as the core, mesoporous silica (mSiO2) doped with hydroxyapatite (HAP) as the inorganic hybrid shell and physically loaded with doxorubicin hydrochloride (DOX·HCl) are prepared (DOX/GNR/mSiO2/HAP, DNPs). DNPs nanoparticles have a typical core-shell structure. The gold nanorods as the core have extremely high light-to-heat conversion efficiency. Under the irradiation of near-infrared light, light can be converted into heat. The inorganic hybrid shell is a drug reservoir. The excellent photothermal response of gold nanorods combined with the excellent pH response of hydroxyapatite can obtain slow and sustained release of chemotherapeutic drugs. In vivo and in vitro anti-tumor cell activity study show that the DNPs in the laser showed stronger cytotoxicity than the other groups. Compared to chemotherapy and phototherapy alone, DNPs selectively accumulate in the tumor through the enhanced penetration and retention (EPR) effects. and have the unified function of hyperthermia and chemotherapy, and have significant inhibitory effect on tumor growth. Therefore, this study provides a new idea for the study of the combination of multiple therapeutic methods in the treatment of cancer.

Abstract
The development of Fe-coordination polymer-based nanoparticles, with safe and high anti-tumor effects, for the treatment of tumor is facing challenges such as limited resources and poor targeting. In this study, we prepared Fe-polyhydroxy coordination polymer nanoparticles (TA-Fe@MNPs), based on tartaric acid (TA)-Fe(III) coordination polymer as the new photothermal agent, mannose (M) as the target, and bovine serum albumin (BSA) and polyethyleneimine (PEI) as the carrier materials, and investigated them for targeting the multifunctional therapy of tumors. The TA-Fe@MNPs synthesized via a simple coordination of Fe3+ with TA, bovine serum albumin, and polyethyleneimine under ambient conditions exhibited an appropriate size (~125 nm), electrically neutral surfaces, good biocompatibility, and low normal cell toxicity. The TA-Fe@MNPs are the first to exhibit a remarkable photothermal performance. They also showed a pH-sensitive Fenton-like response that was further enhanced via glutathione response. Interestingly, after a single injection, the TA-Fe@MNPs could be retained at the tumor site for 36 h with an effective photothermal dose, which was attributed to the reduced protein adsorption and slow elimination in tumor cells with the aid of M modification and carrier materials, while that for the TA-Fe@NPs did so for only 2 h. Tumor ablation was demonstrated by in vivo photothermal and chemokinetic therapy using TA-Fe@MNPs, and their safety was evident from the weight changes and blood parameters. These results indicated that the TA-Fe@MNPs, as new photothermal and CDT agents, have the potential to be used in clinical tumor therapy nanoplatforms.

Abstract
This study investigated the efficiency and the related mechanisms of a new absorption enhancer, DL-malic acid (MA), on the oral bioavailability of docetaxel (DTX). Polyethylene glycol polycarbonate (PEG-PCL) modified liposomes (PLip) were prepared for DTX, and incorporated into the pH-sensitive microspheres (MS) with sustained release. MA decreased the transepithelial electrical resistance (TEER) across a Caco-2 cell monolayer by 20% and 57% after 2 and 3 h of co-incubation with DTX-PLip and the cells, respectively, indicating that MA could open tight junctions but not instantaneously. After long enough exposure (4 h) of MA to the small intestine of rats, only the absorption rate constant (ka) of DTX-PLip, but not Duopafei®, was increased, which could be related to the intestinal mucosal permeability of DTX. After co-administration in rats, MA significantly enhanced the oral bioavailability of DTX in DTX-PLip-MS from 44.67% to 81.27%, rather than DTX-PLip and Duopafei®, which could be related to the prolonged intestinal retention time of DTX-PLip via the MS and the promoted drug intercellular transport by MA. The absorption-enhancing effects of MA on DTX-PLip-MS were further confirmed by in vivo imaging. The above findings suggest that MA served as a new and efficient absorption enhancer for DTX-PLip-MS.HIGHlIGHTSIn this study, malic acid as a new absorption enhancer for DTX in polymer-liposome (PLip) embedded in pH-sensitive microspheres (MS) was found for the first time.The malic acid could significantly enhance oral bioavailability of DTX in DTX-PLip-MS (from 44.67 % to 81.27%) rather than Duopafei® and DTX-PLip after co-administration.The absorption enhancement may be closely related to the intestinal retention time and mucosal permeability.These findings will provide an important reference for the study of absorption enhancers for promoting intercellular insoluble drug transport.

Abstract
The present study aimed to formulate and optimize 2ME-loaded PMs (2ME-PMs) for enhancing the anticancer activity of 2ME in prostate cancer (PC). The 2ME-PMs were formulated using PEG-PLGA (PL), Tween 80 (TW80), and alpha-lipoic acid (ALA). The optimization was carried out using a Box-Behnken design with the PL, TW80, and ALA as the independent variables and particle size (PS) as the response. The formulation was optimized for the lowest possible PS, and the software suggested optimum formula with 100.282 mg, 2%, and 40 mg for PL, TW80, and ALA, respectively. The optimized PMs had spherical morphology with PS of 65.36 ± 2.2 nm, polydispersity index (PDI) of 0.273 ± 0.03, and entrapment efficiency of 65.23 ± 3.5%. The in vitro drug release was 76.3 ± 3.2% after 24 h. The cell line studies using PC-3 cells showed IC50 values of 18.75 and 54.41 µmol for 2ME-PM and 2ME, respectively. The estimation of tumor biomarkers was also carried out. The tumor biomarkers caspase-9 (17.38 ± 1.42 ng/mL), tumor protein P53 (p53) (1050.0 ± 40.9 pg/mL), nitric oxide (NO) (0.693 ± 0.03 pg/mL), interleukin-1β (IL-1β) (25.84 ± 2.23 pg/mL), nuclear factor kappa B (NF-kB) (0.719 ± 0.07 pg/mL), interleukin-6 (IL-6) (2.53 ± 0.16 folds), and cyclooxygenase-2 (COX-2) (3.04 ± 0.5 folds) were determined for 2ME-PMs and the results showed that these values changed significantly compared to those of 2ME. Overall, the results showed that the formulation of 2ME to 2ME-PMs enhances the anticancer effect. The exploration of the combined advantages of PEG, PLGA, ALA, and PMs in cancer therapy and the delivery of 2ME is the major importance of this research work. PEG reduces the elimination of 2ME, PLGA enhances 2ME loading, ALA has an inherent apoptotic effect, and PMs can efficiently target tumor cells.

Oral Drug Delivery: Conventional to Long Acting New-Age Designs. Eur J Pharm Biopharm 2021; 162:23-42. [PMID: 33631319 DOI: 10.1016/j.ejpb.2021.02.008] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 01/16/2021] [Accepted: 02/14/2021] [Indexed: 12/13/2022]
Abstract
The Oral route of administration forms the heartwood of the ever-growing tree of drug delivery technology. It is one of the most preferred dosage forms among patients and controlled release community. Despite the high patient compliance, the deliveries of anti-cancerous drugs, vaccines, proteins, etc. via the oral route are limited and have recorded a very low bioavailability. The oral administration must overcome the physiological barriers (low solubility, permeation and early degradation) to achieve efficient and sustained delivery. This review aims at highlighting the conventional and modern-age strategies that address some of these physiological barriers. The modern age designs include the 3D printed devices and formulations. The superiority of 3D dosage forms over conventional cargos is summarized with a focus on long-acting designs. The innovations in Pharmaceutical organizations (Lyndra, Assertio and Intec) that have taken giant steps towards commercialization of long-acting vehicles are discussed. The recent advancements made in the arena of oral peptide delivery are also highlighted. The review represents a comprehensive journey from Nano-formulations to micro-fabricated oral implants aiming at specific patient-centric designs.

Abstract
Nanoparticle-structuring aimed at the acetic acid (A) transporter on intestinal epithelial cells and tumor cells is a new potential strategy to enhance oral bioavailability and anti-tumor efficacy. In this study, chitosan (CS) was modified with hydrophilic A and hydrophobic lipoic acid (L), to produce ACSL. A novel ACSL-modified multifunctional liposomes (Lip) loaded with docetaxel (DTX; DTX-ACSL-Lip) was then prepared and characterized. DTX-ACSL-Lip recorded higher pH sensitivity and slower release than DTX-Lip and showed dithiothreitol (DTT) response release. DTX-ACSL-Lip uptake by Caco-2 cells was also significantly enhanced mainly viaA transporters compared with DTX-Lip. ACSL modification of DTX-Lip also improved oral bioavailability by 10.70-folds, with a 3.45-fold increase in Cmax and a 1.19-fold prolongation in retention time of DTX in the blood. Moreover, the grafting degree of A significantly affected cell uptake and oral bioavailability. They also showed a significant (1.33-fold) increase in drug intratumoral distribution, as well as an increase in tumor growth inhibition rate from 54.34% to 87.51% without weight loss, compared with DTX-Lip. Therefore, modification of DTX-Lip with ACSL can significantly enhance the oral bioavailability and anti-tumor efficacy of DTX without obvious toxicity, confirming the potential of the dual strategy of targeting A transporter and controlled drug release in tumor cells in oral therapy of tumor.

Abstract
Amentoflavone (AMF) is a kind of biflavonoids existing in Ginkgo biloba leaves. It has many biological activities, such as antioxidant, anti-inflammatory, anti-bacterial, antiviral, hypoglycemic, anti-tumor and inducing apoptosis. However, its solubility and bioavailability are poor and there are a few studies on it in vivo. In this study, to improve its solubility and bioavailability, the nanomicelles were prepared with TPGS and soluplus as carriers for the first time. The particle size, Zeta potential, encapsulation efficiency, drug loading, stability, cytotoxicity, cellular uptake, and metabolites in rats were studied. Cytotoxicity, cellular uptake, and metabolites in rats of AMF-loaded TPGS/soluplus mixed micelles were compared with those of AMF. As a result, AMF-loaded TPGS/soluplus mixed micelles with a particle size of 67.33 ± 2.01 nm and Zeta potential of -0.84133 ± 0.041405 mV were successfully prepared. The encapsulation efficiency and drug loading of the mixed nanomicelles were 99.18 ± 0.76% and 2.47 ± 0.01%, respectively. The physical and chemical properties of the mixed micelles were stable within 60 d, and the cytotoxicity of the mixed micelles was much greater than that of AMF monomers. Thirty-four kinds of metabolites of AMF were identified in rats. The metabolites were mainly distributed in rat feces. No metabolites were detected in bile and plasma. 14 kinds of metabolites of the mixed micelles in rats were detected, including 11 in feces, 6 in urine, and 3 in plasma, which indicated that the bioavailability of AMF has been improved. And the toxicity to cancer cells was enhanced, which laid a foundation for the development of new drugs.

Abstract
Osteosarcoma (OS) occurs in both children and adolescents and leads to a poor prognosis. 2-methoxyestradiol (2-ME) has a strong antitumor effect and is effective against numerous types of tumor. However, 2-ME has a low level of antitumor effects in OS. The present study investigated the effects of 2-ME on the proliferation and apoptosis of human MG63 OS cells. The potential biological mechanisms by which 2-ME exerts its biological effects were also investigated in the present study. The results of the present study demonstrated that 2-ME inhibited the proliferation of OS cells in a time- and dose-dependent manner, induced G2/M phase cell cycle arrest and early apoptosis. The expression levels of vascular endothelial growth factor (VEGF), Bcl-2 and caspase-3 were measured via western blotting and reverse transcription-quantitative PCR. As the concentration of 2-ME increased, the RNA and protein expression levels of VEGF and Bcl-2 decreased gradually, whereas the expression of caspase-3 increased gradually. In addition, tumor growth in nude mice was suppressed by 2-ME with no toxic side effects observed in the liver or kidney. Immunohistochemistry demonstrated that the expression levels of Bcl-2 and VEGF were significantly lower, and those of caspase-3 were significantly higher in test mice compared with the control group. TUNEL staining of xenograft tumors revealed that with increased 2-ME concentration, the number of apoptotic cells also gradually increased. Thus, 2-ME effectively inhibited the proliferation and induced apoptosis of MG63 OS cells in vitro and in vivo with no obvious side effects. The mechanism of the anticancer effect of 2-ME may be associated with the actions of Bcl-2, VEGF and caspase-3.

Abstract
Background:Conventionally, anti-cancer agents were administered through the intravenous route. The major drawbacks associated with the intravenous route of administration are: severe side effects, need of hospitalization, nursing care, and palliative treatment. In order to overcome the drawbacks associated with the intravenous route of administration, oral delivery of anti-cancer agents has gained tremendous interest among the scientific fraternity. Oral delivery of anti-cancer agents principally leads to a reduction in the overall cost of treatment, and aids in improving the quality of life of patients. Bioavailability of drugs and inter-subject variability are the major concerns with oral administration of anti-cancer agents. Factors viz. physicochemical and biological barriers (pre-systemic metabolism and transmembrane efflux of the drug) are accountable for hampering oral bioavailability of anti-cancer agents can be efficiently overcome by employing nanocarrier based drug delivery systems. Oral delivery of anticancer agents by employing these drug delivery systems will not only improve the quality of life of patients but will also provide pharmacoeconomic advantage and lead to a reduction in the overall cost of treatment of life-threatening disease like cancer.Objective:This article aims to familiarize the readers with some of the recent advancements in the field of nanobased drug delivery systems for oral delivery of anticancer agents.Conclusion:Advancement in the field of nanotechnology-based drug delivery systems has opened up gateways for the delivery of drugs that are difficult to administer orally. Oral delivery of anti-cancer agents by these drug delivery systems will not only improve the quality of life of patients but will also provide pharmacoeconomic advantage and lead to a reduction in the overall cost of treatment of life-threatening disease like cancer.

Abstract
A rotigotine (ROT)-loaded polymer micelles thermosensitive gel (ROT-PM-TSG) delivery system was engineered to enhance the solubility of the drug, prolong the residence time, and increase the concentration of the drug in the brain tissue. First, ROT-loaded polymer micelles (ROT-PM) were tailored and optimized. The average particle size, encapsulation efficiency, and drug loading of the ROT-PM were (88.62 ± 1.47) nm, (93.5 ± 0.79) %, and (19.9 ± 0.60) %. The optimal ROT-PM-TSG formulation contained 22% P407 and 2% P188 with a gelation temperature of about 32.3 °C and a pH of 5.186. In vivo, the MRT of ROT-PM and ROT-PM-TSG nasal administration was 1.43 and 1.79 times extended than that of the intravenous. In comparison with the intravenous group, the distribution of ROT in olfactory bulb, cerebrum, cerebellum and striatum was 276.6%, 170.5%, 166.5% and 184.4%, respectively. In conclusion, the ROT-PM-TSG system has proven to be a potential application prospect as a ROT nose-to-brain delivery system.

Abstract
In order to increase the oral bioavailability and antidiabetic effect of amentoflavone with multimechanisms, an oral micelle system was developed by using a N-vinyl pyrrolidone-maleate-guerbet alcohol monoester polymer for the first time, which was designated as P(NVP-MGAM)/AF. After oral administration, P(NVP-MGAM)/AF enhanced the oral bioavailability of amentoflavone, which was approximately 3.2 times that of amentoflavone solution. The animal study using the KKAy insulin-resistant diabetes mouse model indicated that it regulates the expression and activity of downstream signaling factors and proteins by lowering blood lipids, reducing inflammatory responses and activating the peroxisome proliferator-activated receptor (PPAR) γ signaling pathway and PI3K/Akt signaling pathway. After being made into micelles, it is more effective because of its better absorbability and bioavailability. The results from this study provide a theoretical basis for the clinical application of amentoflavone for diabetes treatment. The oral micelles of P(NVP-MGAM)/AF may become one of the most potent drugs in the treatment of diabetes mellitus, which opens up a new way for the prevention and treatment of diabetes.

Abstract
The primary purpose of the present study was to design and optimize a solid lipid nanoparticle (SLN) formulation of the poorly water-soluble drug 2-methoxyestradiol (2-ME) to improve its oral bioavailability and prolong the duration of therapeutic drug level. SLN was modified by amphipathic PEG-PCL (PLN) and then encapsulated in pH-sensitive microparticles (MP) by spray drying technology. Several properties of 2-ME PLN-MP were characterized including particle size, drug loading, and drug or PLN release. After oral administration of 2-ME PLN-MP, retention time in mice was evaluated by in vivo imaging technology and the pharmacokinetic parameters in rats were determined by HPLC. The results demonstrated that PEG-PCL modification of 2-ME SLN significantly decreased particle size and delayed drug release without influencing IC50 in 4T1 cells. 2-ME PLN in the microparticles showed significant pH-sensitive release in the simulated gastrointestinal fluid and controlled release in the intestine. The PLN (labelled with IR-780 iodide) prolonged significantly fluorescence duration time compared to the SLN and the prolongation was further enhanced by the PLN-MP formulation. Furthermore, compared with the suspension, the PLN-MP formulation showed a 56.66-fold delay in Tmax, a 10.36-fold extension in MRT and a 140.86-fold increase in the relative bioavailability in the rat. The research work in the paper suggests that the PLN-MP could serve as a practical oral preparation for 2-ME in future cancer therapy.

Abstract
2-Methoxyestradiol (2ME2), as a microtubule and hypoxia-inducible factor-1 (HIF-1) inhibitor, can be used to treat cerebral ischemia-reperfusion (I/R) injury. However, its poor water solubility compromises its efficacy as a neuroprotectant. Herein, we synthesized PEGylated 2ME2 and angiopep-2 capped PEGylated 2ME2 and fabricated angiopep-2 modified PEGylated 2ME2 micelles containing free 2ME2 (ANG-PEG-2ME2/2ME2) via emulsion-solvent evaporation method. The effect of the micelles on ischemia-reoxygenation injury was evaluated by oxygen-glucose deprivation/reoxygenation (OGD/R) models with different degrees of PC12 cell damage. In comparison with free 2ME2, the micelles significantly increased the cell viability, inhibited reactive oxygen species (ROS) generation and apoptosis for PC12 cells with 0.5 and 4 h OGD followed by 24 h reoxygenation. Taken together, the angiopep-2 modified 2ME2-loaded micelles could effectively reduce the injury of PC12 cells induced by OGD/R.
