Cancer is the leading cause of death worldwide. Nanomaterials and nanotechnologies could provide potential solutions. In this research, a novel biodegradable poly(lactide-co-glycolide)-d-a-tocopheryl polyethylene glycol 1000 succinate (PLGA-TPGS) random copolymer was synthesized from lactide, glycolide and d-a-tocopheryl polyethylene glycol 1000 succinate (TPGS) by ring-opening polymerization u...

The potential of PLGA-nanoparticles as a carrier of amphotericin B and doxorubicin against visceral leishmaniasis was evaluated by macrophage-mediated drug targeting approach. PLGA-nanoparticles were modified by coating them with macrophage-specific ligand-lectin. Prior to in-vitro studies, characterization studies were carried out systematically include particle size, surface morphology, perce...

Nanoparticles hold tremendous potential as an effective drug delivery system. In this review we discussed recent developments in nanotechnology for drug delivery. To overcome the problems of gene and drug delivery, nanotechnology has gained interest in recent years. Nanosystems with different compositions and biological properties have been extensively investigated for drug and gene delivery ap...

Membrane permeability and P-glycoprotein (P-gp) efflux system are regulating factors in the drug brain penetration. Recently, some drug delivery systems have been developed to overcome these limitations. In this study, Metoclopramid has been encapsulated in PLGA nanoparticles using the emulsification/solvent evaporation technique for in vitro evaluation of the effect of PLGA nanoparticles on BB...

To increase the encapsulation of hydrophilic antitumor agent daunorubicin (DNR) and multidrug resistance reversal agent tetrandrine (Tet) in the drug delivery system of nano-particles (NPs), a functional copolymer NP composed of poly(lactic-co-glycolic acid) (PLGA), poly-L-lysine (PLL), and polyethylene glycol (PEG) was synthesized and then loaded with DNR and Tet simultaneously to construct DN...

The present work aimed to develop and evaluate a colloidal system composed of poly (DL-lactideco-glycolide) (PLGA) nanoparticles (NPs) associated with chlorambucil (CHB) and its effects on cancer cells. The nanoparticles showed %EE (>92%), a mean particle size in the range of 240 to 334 nm and zeta potential of −16.7 to −26.0 mV. In vitro release profile showed a biphasic pattern, with an initi...

Docetaxel is a highly potent anticancer agent being used in a wide spectrum of cancer types. There are important matters of concern regarding the drug's pharmacokinetics related to the conventional formulation. Poly(lactide-co-glycolide) (PLGA) is a biocompatible/biodegradable polymer with variable physicochemical characteristics, and its application in human has been approved by the United Sta...

Abstract Ketotifen fumarate is a non-bronchodilator anti-asthmatic drug which inhibits the effects of certain endogenous substances known to be inflammatory mediators, and thereby exerts antiallergic activity. The present study describes the formulation of a sustained release nanoparticle (NP) drug delivery system containing ketotifen, using poly (D,L lactide-co-glycolide acid) (PLGA). Biodegra...
