Abstract
Inulin (INU) is a versatile natural polysaccharide primarily derived from chicory roots. INU possesses the unique quality of evading digestion or fermentation in the early stages of the human digestive tract, instead reaching the lower colon directly. Exploiting on this distinctive attribute, INU finds application in the creation of targeted carrier systems for delivering drugs tailored to colon-related diseases. This study presents a novel method for synthesizing highly stable and non-aggregatory inulin nanoparticles (INU NPs) by ionotropic gelation method, using calcium chloride as crosslinker and natural honey as a stabilizing agent. Different formulation and process parameters were optimized for the synthesis of monodispersed INU NPs. These INU NPs efficiently encapsulated a hydrophilic drug irinotecan hydrochloride trihydrate (IHT) and drug loaded formulation (IINPs) demonstrated excellent colloidal and storage stabilities. Notably, these IINPs exhibited pH-dependent drug release, suggesting potential for colon-specific drug delivery. Anticancer activity of the NPs was found significantly higher in comparison to IHT through cytotoxicity and apoptosis studies against human colorectal carcinoma cells. Overall, this study revealed that the INU NPs synthesized by ionotropic gelation will be an efficient nanocarrier system for colon-targeted drug delivery due to their exceptional biocompatibility and stability in stomach and upper intestinal conditions.

Abstract
The potential to target anticancer drugs directly to cancer cells is the most difficult challenge in the current scenario. Progressive works are being done on multifarious receptors and are on the horizon, expected to facilitate tailored treatment for cancer. Among several receptors, one is the sialic acid (SA) receptor by which cancer cells can be targeted directly as hyper sialylation is one of the most distinguishing characteristics of cancer cells. SA receptors have shown tremendous potential for tumor targeting because of their elevated expression in a range of human malignancies including prostate, breast, gastric cells, myeloid leukemia, liver, etc. This article reviews the overexpression of SA receptors in various tumors and diverse strategies for targeting these receptors to deliver drugs, enzymes, and genes for therapeutic applications. It also summarizes the diagnostic applications of SA-grafted nanoparticles for imaging various SA-overexpressing cancer cells and technological advances that are propelling sialic acid to the forefront of cancer therapy.

Abstract
Recently, instead of creating new active compounds, scientists have been working to increase the bioavailability and residence time of existing drugs by modifying the characteristics of the delivery systems. In the present study, a novel mucoadhesive bioconjugate (SN-XG-SH) was synthesized by functionalizing a polysaccharide xanthan gum (XG) with cysteamine hydrochloride (CYS) and a lipid stearylamine (SN). FTIR, CHNS and 1H NMR studies confirmed the successful synthesis of SN-XG-SH. Mucoadhesion of the thiolated XG was enhanced and evaluated by different methods. Disulfide bond formation between thiolated XG and skin mucus enhances mucoadhesive behavior. The mucoadhesive bioconjugate was used to prepare nanoparticles for the delivery of hydrophobic biochanin-A (Bio-A) for the treatment of melanoma. The thiolated xanthan gum nanoparticles also demonstrated high drug entrapment efficiency, sustained drug release, and high storage stability. The drug loaded nanoparticles (Bio-A@TXNPs) significantly improved the cytotoxicity of Bio-A against human epidermoid cancer cells (A431 cells) by inducing apoptosis and changing mitochondrial membrane potential. In conclusion, thiolation of XG improves its mucoadhesive properties and prolongs the release of Bio-A. Thus, thiolated XG conjugate has a high potential for use as a bioadhesive agent in controlled and localised delivery of drugs in different skin diseases including melanoma.

Abstract
In the past few years, manganese-based nanostructures have been extensively investigated in the biomedical field particularly to design highly biocompatible theranostics, which can not only act as efficient diagnostic imaging contrast agents but also deliver the drugs to the target sites. The nanoscale size, large surface area-to-volume ratio, availability of cheap precursors, flexibility to synthesize nanostructures with reproducible properties and high yield, and easy scale up are the major reasons for the attraction towards manganese nanostructures. Along with these properties, the nontoxic nature, pH-sensitive degradation, and easy surface functionalization are additional benefits for the use of manganese nanostructures in biomedical and pharmaceutical sciences. Therefore, in this review, we discuss the recent progress made in the synthesis of manganese nanostructures, describe the attempts made to modify their surfaces to impart biocompatibility and stability in biological fluids, and critically discuss their use in magnetic resonance imaging, drug and gene delivery, hyperthermia, photothermal/photodynamic, immunotherapy, biosensing and tumor diagnosis.

Abstract
Chrysin is a natural bioactive compound with potential biological activities. However, unfavorable physicochemical properties of native chrysin make it difficult to achieve good therapeutic efficacies. In this study, poly(ethylene) glycol (PEG4000)-conjugated chrysin nanoparticles were prepared. The PEG4000 was conjugated to chrysin through cis-aconityl and succinoyl linkers to achieve tumor microenvironment-specific drug release from PEGylated nanoparticles. The conjugation of PEG and chrysin via succinoyl (PCNP-1) and cis-aconityl (PCNP-2) linkers was confirmed by the 1H NMR and FTIR analysis. The nanoparticles were characterized by DLS, TEM, XRD, and DSC analysis. Comparatively, PCNP-2 showed a better drug release profile and higher anticancer activity against human breast cancer cells than chrysin or PCNP-1. The apoptosis studies and colony formation inhibition assay revealed that the PCNP-2 induced more apoptosis and more greatly controlled the growth of human breast cancer cells than pure chrysin. Thus, the use of PCNPs may help to overcome the issues of chrysin and could be a better therapeutic approach.

Abstract
Achieving controlled and site-specific delivery of hydrophobic drugs in the colon environment is a major challenge. The primary goal of this research was to synthesize inulin-stearic acid (INU-SA) conjugate and to evaluate its potential in the site-specific delivery of genistein (GEN) for the treatment of colon cancer. INU is a hydrophilic polysaccharide biological macromolecule was modified with hydrophobic SA to form amphiphilic conjugate (INU-SA) which can self-assemble into spherical nanoparticles with interesting drug release properties. The hydrophobic GEN was encapsulated into the INU-SA conjugate to prepare GEN loaded nanoparticles (GNP). The prepared GNP possessed nano size (115 nm), good colloidal dispersibility (0.066 PDI), and high drug encapsulation efficiency (92.2%). The release behaviour of GNP indicated the site-specific release of GEN, only 3.4% at gastric pH while 94% at intestinal pH. The prepared GNP showed potential cytotoxicity against HCT 116 human colorectal cancer cells, as demonstrated by antiproliferation and apoptosis assays. The observed half maximum inhibitory concentration (IC50) value of GNP (5.5 μg/mL) was significantly lower than pure GEN (28.2 μg/mL) due to higher cellular internalization of GNP than free GEN. Therefore, this research suggests a way to improve the therapeutic effectiveness of natural biomolecules using modified and biocompatible polysaccharide INU.

Abstract
This study reports the development and pre-clinical evaluation of biodrug using RNA interference and nanotechnology. The major challenges in achieving targeted gene silencing in vivo include the stability of RNA molecules, accumulation into pharmacological levels, and site-specific targeting of the tumor. We report the use of Inulin for coating the arginine stabilized manganese oxide nanocuboids (MNCs) for oral delivery of shRNA to the gut. Furthermore, bio-distribution analysis exhibited site-specific targeting in the intestines, improved pharmacokinetic properties, and faster elimination from the system without cytotoxicity. To evaluate the therapeutic possibility and effectiveness of this multimodal bio-drug, it was orally delivered to Apc knockout colon cancer mice models. Persistent and efficient delivery of bio-drug was demonstrated by the knockdown of target genes and increased median survival in the treated cohorts. This promising utility of RNAi-Nanotechnology approach advocates the use of bio-drug in an effort to replace chemo-drugs as the future of cancer therapeutics.

Abstract
Chemotherapy is an essential component of breast cancer therapy, but it is associated with serious side effects. Herein, a pluronic F68-based pH-responsive, and self-assembled nanomicelle system was designed to improve the delivery of paclitaxel (PTX) to breast cancer cells. Two pH-responsive pluronic F68-PTX conjugates i.e. succinoyl-linked conjugate (F68-SA-PTX) and cis-aconityl-linked conjugate (F68-CAA-PTX) were designed to respond the varying pH-environment in tumour tissue. Although both the linkers showed pH-sensitivity, the F68-CAA-PTX exhibited superior pH-sensitivity over the F68-SA-PTX and achieved a more selective release of PTX from the self-assembled nanomicelles. The prepared nanomicelles were characterized by dynamic light scattering, transmittance electron microscopy, differential scanning calorimetry and powder X-ray diffraction techniques. The anticancer activity of prepared nanomicelles and pure PTX were evaluated by 2D cytotoxicity assay against breast cancer cell line MDA-MB-231 and in the real tumour environments i.e. 3D tumor spheroids of MDA-MB-231 cells. The highest cytotoxicity effect of PTX was observed with F68-CAA-PTX nanomicelles followed by F68-SA-PTX and free PTX. Further, the F68-CAA-PTX nanomicelles also induced significant apoptosis with a combination of increase in ROS generation, decrease in the depolarisation of MMP and G2/M cell cycle arrest. These observed results provide a new insight for breast cancer treatment using pluronic nanomicelles.

Abstract
5-Fluorouracil (5-FU) is one of the most prescribed drugs and the major component of chemotherapy for the treatment of colorectal cancer. In this study, we have designed arginine-functionalized manganese oxide nanocuboids (Arg@MNCs) for the effective delivery of 5-FU to colon cancer cells. Arginine was used as multifunctional agent to provide stability to MNCs, achieve high drug loading, control the release of loaded drug, and improve delivery to cancer cells. The synthesized Arg@MNCs were characterized by DLS, TEM, XRD, FTIR, XPS, TGA, and VSM analysis. The structural and morphological analysis by TEM showed cuboid-shaped MNCs with average particle size ∼15 nm. Biodegradation studies indicated that the Arg@MNCs were degraded at endolyosomal pH in 24 h while remaining stable at physiological pH. Hemolytic toxicity studies revealed the safety and nontoxic nature of the prepared MNCs. 5-FU-loaded Arg@MNCs showed significant control over the release of 5-FU, decrease in the hemolytic toxicity of loaded 5-FU but higher in vitro anticancer activity against HCT 116 and SW480 human colon cancer cells. Importantly, both the bare MNCs and Arg@MNCs showed excellent T1 and T2MR relaxivity under 3.0 T MRI scanner. Thus, the nanostructures developed in this study, i.e., 5-FU-Arg@MNCs could overcome the issues of both MNCs (stability) and 5-FU (low drug loading and nonspecificity) and may be used as a multifunctional theranostic nanocarrier for colon cancer treatment.

Abstract
Nanotechnology has come up as a protean field integrating concepts of alternate drug delivery systems using nanocarriers. The idea of encapsulating a drug molecule into a colloidal carrier like solid lipid nanoparticle has been a promising approach for development of nanomedicines. In this research work, a hydrophobic, natural, and an anticancer bioflavonoid, morin hydrate (MH) was encapsulated into solid lipid nanoparticles to overcome the issues of its poor aqueous solubility and low oral bioavailability. The prepared morin hydrate loaded solid lipid nanoparticles (MSN) were characterized by DLS, FTIR, and DSC analysis. The MSN showed nanoscale size, good steric stability, and release in simulated intestinal fluid. The in-vitro anticancer studies against human cervical cancer cells revealed the higher cytotoxicity of encapsulated MH than free or pure MH. MSN also demonstrated a significant improvement in pharmacokinetics of encapsulated MH.

Abstract
Receptor-mediated endocytosis is key in the success of targeted nanomedicines for the treatment of cancer. Various receptors have been explored for the active targeting of anticancer drugs to avoid the drawbacks of conventional anticancer drugs. This research work aimed to investigate the potential of serotonin (ST)-conjugated Vit-E nanomicelles for the targeted delivery of irinotecan hydrochloride (IRI) to human prostate cancer cells. A ST receptor-targeting conjugate was synthesized by conjugating ST and d-α-tocopheryl polyethylene glycol succinate via a two-step synthesis reaction. The developed formulation demonstrated a size of about 14 nm, a negative zeta potential of around -20 mV, a high drug encapsulation efficiency, and sustained drug release over 48 h. Cytotoxicity studies revealed that ST-conjugated, IRI-loaded nanomicelles (IRI-STNM) were not only toxic to human prostate cancer cells but also eradicate these cells present in the form of 3D spheroids. This cytotoxicity of IRI-STNM was mediated through induction of apoptosis, reactive oxygen species generation, change in mitochondrial membrane potential, and inhibition of cell migration. Further, IRI-STNM performed significantly better than the native IRI and nontargeted nanomicelles, which was led by a higher cellular uptake of IRI-STNM, indicating the role of ST in targeting of drug-loaded nanomicelles.

Abstract
Herein, we introduce a novel amphiphilic bioconjugate (INU-F68-SA), synthesized by functionalization of pluronic F68 with a polysaccharide inulin (INU) and a lipid stearic acid (SA). The synthesis of INU-F68-SA was confirmed by FTIR and 1H-NMR analysis. INU-F68-SA can self-assemble into nanomicelles and therefore, its application in delivering of hydrophobic resveratrol (RSV) was investigated. The RSV-loaded INU-F68-SA nanomicelles (RSNM) had about 172 nm size, spherical shape, 0.237 polydispersity index, and -18 mV zeta potential. More importantly, the RSNM showed high drug entrapment efficiency, controlled drug release and protection of drug during storage. The RSNM significantly enhanced the cytotoxicity of RSV against colorectal cancer cells by inducing apoptosis and changing mitochondrial membrane potential. Further, in-vivo pharmacokinetic experiment indicated an improvement in pharmacokinetics of RSV after administering as RSNM. Thus, the use of self-assembled nanomicelles of amphiphilic INU-F68-SA bioconjugate could be a better alternative to overcome the poor in-vitro and in-vivo performance of RSV.

Abstract
In the past decade, naturally occurring phytoconstituents have emerged as potential therapeutic agents and alternative to synthetic drugs. However, efficient delivery of hydrophobic phytoconstituents into the body with desired therapeutic efficacy is a key challenge for the pharmaceutical industries due to their insolubility in water and low oral bioavailability. Nanosuspension formulations have shown promises to improve the delivery of the hydrophobic molecules with simultaneously avoiding the drawbacks like carrier toxicity and scale-up issues of other nanotechnology-based drug delivery systems. In this study, we have used morin hydrate (MH), a flavonol, and developed MH nanosuspension formulation (MHNS) to improve its poor physiochemical properties and low oral bioavailability. Different stabilizers with varying concentrations were investigated for preparing nanosuspension. MHNS was characterized by DLS, TEM, FTIR, DSC, powder XRD and was evaluated for its solubility, dissolution, partition coefficient, in-vitro anticancer activity and pharmacokinetics in rats. The optimized nanosuspension formulation, with a size of <100 nm, is capable of increasing aqueous solubility, dissolution rate, and oral bioavailability of MH. Moreover, the therapeutic efficacy, in terms of cytotoxicity to human lung cancer cells, of MH was also increased after formulating into nanosuspension form.

Abstract
In this study, a serotonin-stearic acid (ST-SA)-based bioconjugate was synthesized for the surface modification of manganese oxide-based nanocuboids (MNCs) for delivering of anticancer drug (i.e., doxorubicin hydrochloride (DOX)) to human liver cancer cells. MNCs were synthesized by chemical precipitation method, and their surface was modified with ST-SA bioconjugate for targeting of MNCs to cancer cells. The ST-SA@MNCs along with DOX showed good colloidal stability, high drug encapsulation (98.3%), and drug loading efficiencies (22.9%) as well as pH-responsive biodegradation. Coating with ST-SA conjugate provided a shield to MNCs which sustained their degradation in an acidic environment. The release of DOX was higher (81.4%) in acidic media than under the physiological conditions (20.5%) up to 192 h. The in vitro anti-proliferation assay showed that ST-SA@MNCs exhibit higher cell growth inhibition compared to that of pure DOX after 48 h of treatment. The cellular uptake and apoptosis studies revealed the enhanced uptake of ST-SA@MNCs in contrast to the MNCs due to overexpressed ST receptor on hepatocellular carcinoma cells and triggered the generation of reactive oxygen species in the cells. Therefore, these results indicated that the DOX-loaded, ST-SA stabilized MNCs improved the therapeutic index of DOX and would be a promising therapeutic candidate for tumor therapy.

Abstract
Four cycloaurated phosphine sulfide complexes, [Au{κ2 -2-C6 H4 P(S)Ph2 }2 ][AuX2 ] [X=Cl (2), Br (3), I (4)] and [Au{κ2 -2-C6 H4 P(S)Ph2 }2 ]PF6 (5), have been prepared and thoroughly characterized. The compounds were found to be stable under physiological-like conditions and showed excellent cytotoxicity against a broad range of cancer cell lines and remarkable cytotoxicity in 3D tumor spheroids. Mechanistic studies with cervical cancer (HeLa) cells indicated that the cytotoxic effects of the compounds involve the inhibition of thioredoxin reductase and induction of apoptosis through mitochondrial disruption. In vivo experiments in nude mice bearing HeLa xenografts showed that treatment with compounds 4 and 5 resulted in significant inhibition of tumor growth (35.8 and 46.9 %, respectively), better than that of cisplatin (29 %). The newly synthesized gold complexes were also evaluated for their in vitro and in vivo anti-inflammatory activity through the study of lipopolysaccharide (LPS)-activated macrophages and carrageenan-induced hind paw edema in rats, respectively.

Abstract
Epigallocatechin-gallate (EGCG) is a potent anti-cancer therapeutic which effectively controls the growth of cancerous cells through a variety of different pathways. However, its molecular structure is susceptible to modifications due to cellular enzymes affecting its stability, bioavailability and hence, overall efficiency. In this study, we have initially encapsulated EGCG in the matrix of solid lipid nanoparticles to provide a stable drug carrier. To confer additional specificity towards gastrin releasing peptide receptors (GRPR) overexpressed in breast cancer, EGCG loaded nanoparticles were conjugated with a GRPR-specific peptide. In-vitro cytotoxicity studies showed that the peptide-conjugated formulations possessed greater cytotoxicity to cancer cell lines compared to the non-conjugated formulations. Further, in-vivo studies performed on C57/BL6 mice showed greater survivability and reduction in tumour volume in mice treated with peptide-conjugated formulation as compared to the mice treated with non-conjugated formulation or with plain EGCG. These results warrant the potential of the system designed in this study as a novel and effective drug delivery system in breast cancer therapy.

Abstract
Inulin (INU) is a flexible, fructan type polysaccharide carbohydrate, mainly obtained from the root of chicory. It is a water-soluble dietary fibre and has been recently approved by the Food and Drug Administration for improving the nutritional values of food products. INU is not digested or fermented in the initial portion of the human digestive system and directly reaches on the distal portion of the colon. Owing to this superior property, INU is specially applied to develop specific carrier systems for localized delivery of drugs related to colon diseases. Several studies proved that the fermented bi-products of INU help the growth and stimulating activity of colon bacteria e.g. Bifidobacterium and Lactobacilli. INU also has several inherent therapeutic effects like reduction of tumor risks, help in calcium ion absorption, anti-inflammatory, antioxidant properties etc. Apart from these, INU has been used for different pharmaceutical applications as a drug carrier, stabilizing agent, cryoprotectant, and an alternative to fats and sugars. Here, we review the applications of INU in different areas of biomedical science, look back into the nutritional effects of INU and outline various routes of administration of INU-based formulations.

Abstract
Gold nanoparticles (GNPs) have emerged as a potential scaffold for a wide range of biomedical applications such as biosensing, drug delivery, and imaging. However, the toxicity of nanoparticles remains a challenge for using them in biological system. The morphology and surface chemistry of GNP can be manipulated by their method of preparation. GNP can be synthesized and functionalized by various methods. This chapter illustrates the synthesis of highly biocompatible GNP using a natural gum, i.e., xanthan gum (XG). Moreover, due to the presence of mannose moiety in XG, these XG-stabilized GNP may also act as self-targeted drug carriers for the delivery of chemotherapeutic agents/siRNA/shRNA to mannose receptor overexpressing cancer cells.

Abstract
Targeted drug delivery has shown promise in improving the therapeutic efficacy of anticancer drugs. Gemcitabine hydrochloride (GEM) is a broad-range chemotherapeutic agent for the treatment of various cancers. However, systemic use of free GEM is restricted because of its poor physicochemical properties and nonspecific drug delivery, resulting in dose-dependent adverse effects. In this study, a fucose-conjugated graphene oxide (GO)-based smart targeted nanocarrier system was designed to provide high loading, sustained release, and targeted high concentrations of GEM to cancer cells. Fucose-conjugated GO nanosheets (FGONS) and GEM-loaded fucose-conjugated GO nanosheets (GEM-FGONS) were prepared and characterized by various techniques. About 36.2 % of GEM was loaded to the FGONS, which showed a pH-dependent release over a period of 48 h. A colloidal suspension of GEM-FGONS was found to be physiochemically stable for up to 96 h. In cytotoxicity studies, GEM-FGONS demonstrated time- and dose-dependent high toxicities on fucose-receptor-overexpressing MDA-MB-231 human breast cancer cells and A549 human lung cancer cells. Moreover, targeted formulations were more efficacious than non-targeted or free GEM. Overall, bioconjugation of fucose helps in the stabilizing and targeting of graphene oxide nanosheets.

Abstract
Morin hydrate (MH) is a naturally occurring polyphenolic flavonol compound. It has been recently investigated for its many biological activities such as anti-inflammatory, anticancer, antioxidant, antiarthritic, antifertility, antiplasmodic and anticancer. Though these outcomes are very promising, its low aqueous solubility and oral bioavailability restrict its clinical uses. Therefore, in this study we report pluronic F68 and stearic acid conjugated (F68-SA) nanomicelles for increasing oral bioavailability of MH. The MH loaded F68-SA nanomicelles (MHNM) were prepared by the solvent evaporation method. The MHNM were extensively characterized for the size, surface charge, stability, morphology, critical micelle concentration, drug content, and in-vitro drug release. The cell viability assay depicted a significant increase in cytotoxicity of MH against A549 human lung cancer cells after incubating as MHNM. Exposure of A549 cells to MHNM induced cell apoptosis in the cells as observed in apoptosis studies. Pharmacokinetic studies in Sprague-Dawley rats revealed that MHNM significantly increased the oral bioavailability of MH as compared to pure drug. Therefore, the novel, surfactant-lipid based micellar system is an effective solubilizing and delivering system for oral administration of poorly water soluble drugs like MH.

Abstract
BACKGROUND Nanosuspension is a biphasic system consisting of native drug particles dispersed in an aqueous surfactant or polymeric solution with a particle size between 10 to 1000 nm. In contrast to other drug delivery systems, nanosuspension offer the unique advantage of increasing solubility of the native drug resulting into faster drug absorption and hence achieving faster maximum plasma concentration. HYPOTHESIS/PURPOSE The present study aims to evaluate surfactants/polymer stabilized nanosuspensions of naringenin (NN), a phytomedicine, to surpass its poor physiochemical properties and low oral bioavailability. STUDY DESIGN Optimization and characterization (DLS, SEM, PXRD and DSC) of nanosuspensions followed by in-vitro drug dissolution studies and pharmacokinetic study in male Sprague-Dawley rats were performed. METHODS Nanosuspensions were prepared by precipitation-ultrasonication method with varying concentrations of different surfactants and polymer such as sodium cholate (SC), sodium lauryl sulphate (SLS), poly ethylene glycol 4000 (PEG), polysorbate 80 (Tween® 80), poloxomer-188 and D-α-Tocopherol polyethylene glycol 1000 succinate (TPGS or Vitamin E-TPGS). RESULTS Nanosuspension prepared with 0.5% w/v d-α-Tocopherol polyethylene glycol 1000 succinate (TPNS) and 7.5 mg NN, showed the smallest size of 118.1 ± 2.7 nm. TPNS showed increase in drug dissolution in simulated gastric fluid pH 1.2 (SGF) and phosphate buffer pH 6.8 (PB). TPNS demonstrated an improved pharmacokinetic profile compared to pure NN resulting 2.14 and 3.76 folds increase in Cmax and AUC, respectively. In addition, TPNS were stable over a period of six months. CONCLUSION The developed formulation strategy of nanosuspension could be exploited to improve the solubility and bio-availability of poorly soluble NN and other phytomedicines.

Abstract
Natural drugs have emerged as potential alternatives to synthetic drugs to avoid their toxic effects. Morin hydrate (MH) is a natural therapeutic agent, obtained from Maclura pomifera, Maclura tinctoria and Psidium guajava. Solubility and degradation kinetics of morin hydrate in different physiological media, namely, 0.1 N HCl (pH 1.2), sodium acetate buffer (pH 5.0), water (pH 7.0), phosphate buffer saline (pH 7.4) and tris base (pH 9.0), were investigated via classical spectroscopic methods. Stability studies of MH were performed to determine the effect of different pH media, temperature (room and freeze) and light on the degradation kinetics. Solubility and stability of MH varied significantly in different biological media and storage conditions. Solubility of MH was pH-dependent and increased with the increase in pH. Degradation kinetics and regression values (r2) values were calculated from the linear fitted models of zero, first and second order kinetics. The stability of morin hydrate depends on pH, temperature, and light.![]()

Abstract
Aim: To synthesize cRGDfK peptide conjugated poly(γ-glutamic acid)-phenylalanine nanoparticles to improve the therapeutic efficacy of camptothecin (CPT) against glioblastoma multiforme. Methods: Peptide-conjugated, drug-loaded nanoparticles (cRGDfK-conjugated camptothecin-loaded PGA–PA nanoparticles [RCPN]) were prepared and physico-chemically characterized using different techniques. Nanoparticles were evaluated for in vitro anticancer activity, cellular uptake, induction of apoptosis and wound healing cell migration against U87MG human glioblastoma cells. Results: RCPN, with a particle size of <100 nm and 65% CPT encapsulation efficiency, exhibited a dose- and time-dependent cytotoxicity to glioblastoma cells. Compared with native CPT or unconjugated nanoparticles, RCPN induced apoptosis, increased reactive oxygen species generation and inhibited U87MG cell migration. Conclusion: cRGDfK-mediated and amphiphilic copolymer-based nanomedicines represent a new approach for improved delivery of anticancer drugs to and treatment of glioblastoma multiforme.

Abstract
We present a dendrimer-based hybrid formulation strategy to explore the potential of poly (amidoamine) PAMAM dendrimers to be used as drug carriers for combination therapy of an anti-hypertensive drug ramipril (RAPL) and a diuretic hydrochlorothiazide (HCTZ). The drug-dendrimer complexes were prepared by phase-equilibration method. The results showed that the solubility of RAPL and HCTZ was dependent on dendrimer concentration and pH of dendrimer solution. The solubility profile of both RAPL and HCTZ dendrimer complexes illustrated a non-linear relationship with dendrimer concentration. At 0.8% (w/v) dendrimer concentration, solubility of RAPL was increased 4.91 folds with amine-terminated while for HCTZ, solubility enhancement was highest (3.72 folds) with carboxy-terminated. The complexes were characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance analysis and high performance liquid chromatography. In-vitro drug dissolution performance of pure drugs, individual drug loaded dendrimer formulations and hybrid formulations was studied in USP dissolution medium (pH7.0) and in simulated gastric fluid (pH1.2). Dendrimer mediated formulations showed faster and complete dissolution compared to pure RAPL or HCTZ. Surprisingly, similar pattern of dissolution profile was established with hybrid formulations as compared to individual drug loaded dendrimers. The dendrimer-based hybrid formulations were found to be stable at dark and refrigerated conditions up to 5weeks. Conclusively, the proposed formulation strategy establishes a novel multitasking platform using dendrimer for simultaneous loading and delivery of multiple drugs for pharmaceutical applications.

Abstract
Epigallocatechin gallate (EGCG), a green tea polyphenolic catechin, has been known to possess a variety of beneficial biological activities. The in-vitro anti-cancer activity of EGCG is well documented. However, the use of EGCG in modern therapeutics is limited due to its poor bioavailability and limited stability at physiological pH. In this study, we have investigated the stability profiles of EGCG in aqueous solutions using UV-vis spectroscopy. Stability results showed very low stability profile of EGCG at physiological pH with rapid degradation under alkaline conditions. Therefore, we have encapsulated EGCG in solid lipid nanoparticles to increase its stability and evaluated for anticancer activity. The lipid core of nanoparticles not only provides an additional structural reinforcement to the nanoparticle assembly, but also makes it biologically compatible, thereby enabling a stealth vehicle for efficient drug delivery. EGCG loaded nanoparticles (EGCG-SLN) were characterized using dynamic light scattering, Fourier transform infrared spectroscopy and differential scanning calorimetry. EGCG and EGCG-SLN were evaluated for their anticancer activities by cellular proliferation. The cytotoxicity of EGCG-SLN was found to be 8.1 times higher against MDA-MB 231 human breast cancer cells and 3.8 times higher against DU-145 human prostate cancer cells than that of the pure EGCG.

Abstract
Targeted nanomedicines improve the delivery of drugs by increasing the drug concentration at target site, protecting the premature degradation and releasing the encapsulated drug in controlled manner. To make rifampicin (RFN) delivery more effective, we designed and characterized wheat germ agglutinin (WGA) conjugated, RFN loaded solid-lipid nanoparticles (WRSN). Nanoparticles were prepared by solvent emulsification/evaporation and conjugated with fluorescein isothiocyanate-labeled WGA. Important characteristics, such as particle size, zeta potential, encapsulation efficiency, conjugation efficiency and in vitro drug release behavior, were investigated. WGA conjugation to the nanoparticles was confirmed by Fourier Transform Infrared (FTIR) analysis. Conjugation efficiency was determined by fluorescent spectroscopy and Bradford assay. RFN was released from nanoparticles via the diffusion-controlled, non-fickian and supercase II mechanism. A haemaglutination test confirmed that WGA retained its bio-recognition activity and sugar-binding specificity after it was coupled with the nanoparticles. In vitro experiments demonstrated that WRSN interacted more than non-conjugated nanoparticles with porcine mucin. WRSN were stable in the presence of electrolytes up to 1M concentration. Therefore, WGA-conjugated solid lipid nanoparticles could be a promising tool for the controlled delivery of RFN or other anti-tubercular drugs.

Abstract
Aim: Bombesin (BBN)-conjugated polymeric nanoparticles to target docetaxel (DTX) to prostate cancer cells that overexpress gastrin-releasing peptides receptors. Materials & methods: In vitro cytotoxicity, uptake of nanoparticles and inhibition of cell migration were assessed against human prostate cancer cells. Preclinical pharmacokinetic and tissue-distribution studies of nanoparticles were performed in Balb/c mice and results compared with the marketed formulation Taxotere®. Results: BBN-conjugated DTX-loaded nanoparticles exhibited higher cytotoxicity, inhibition of cell migration and colony formation than non-targeted nanoparticles or DTX alone. More BBN-conjugated nanoparticles were taken up at a faster rate than unconjugated nanoparticles. In vivo, this drug delivery improved pharmacokinetics of DTX by increasing mean residence time and decreasing clearance. Conclusion: This study provides an alternate approach for polysorbate-free delivery of DTX, with improved in vivo performance.

Abstract
Silibinin is reported to possess multiple biological activities. However, its hydrophobic nature limits its bioavailability compromising in vivo biological activities. Nanoparticles-based delivery of such molecules has emerged as new technique to resolve these issues. Bio-degradable, compatible and adhesive nature of chitosan has recently attracted its suitability as a carrier for biologically active molecules. This study presents fabrication and characterization of chitosan-tripolyphosphate based encapsulation of silibinin. Various preparations of silibinin encapsulated chitosan-tripolyphosphate nanoparticles were studied for particle size, morphology, zeta-potential, and encapsulation efficiencies. Preparations were also evaluated for cytotoxic activities in vitro. The optimized silibinin loaded chitosan nanoparticles were of 263.7±4.1nm in particle size with zeta potential 37.4±1.57mV. Nanoparticles showed high silibinin encapsulation efficiencies (82.94±1.82%). No chemical interactions between silibinin and chitosan were observed in FTIR analysis. Powder X-ray diffraction analysis revealed transformed physical state of silibinin after encapsulation. Surface morphology and thermal behaviour were determined using TEM and DSC analysis. Encapsulated silibinin displayed increased dissolution and better cytotoxicity against human prostate cancer cells (DU145) than silibinin alone.

Abstract
Abstract Cisplatin is mainly used in the treatment of ovarian, head and neck and testicular cancer. Poor solubility and non-specific interactions causes hurdles in the development of successful cisplatin formulation. There were few reports on poly(amidoamine) (PAMAM) dendrimer-cisplatin complexes for anticancer treatment. But the earlier research was mainly focused on therapeutic effect of PAMAM dendrimer-cisplatin complex, with less attention paid on the formulation development of these complexes. Objective of the present study is to optimize and validate the carboxylate-terminated, EDA core PAMAM dendrimer-based cisplatin formulation with respect to various variables such as dendrimer core, generation, drug entrapment, purification, yield, reproducibility, stability, storage and in-vitro release. Dendrimer-cisplatin complex was prepared by an efficient method which significantly increases the % platinum (Pt) content along with the product yield. Dendrimers showed reproducible (∼27%) platinum loading by weight. Variation in core and generations does not produce significant change in the % Pt content. Percentage Pt content of dendrimeric formulation increases with increase in drug/dendrimer mole ratio. Formulation with low drug/dendrimer mole ratio showed delayed release compared to the higher drug/dendrimer mole ratio; these dendrimer formulations are stable in room temperature. In vitro release profiles of the stored dendrimer-cisplatin samples showed comparatively slow release of cisplatin, which may be due to formation of strong bond between cisplatin and dendrimer. This study will contribute to create a fine print for the formulation development of PAMAM dendrimer-cisplatin complexes.
