Curcumin is a lipophilic molecule with an active ingredient in the herbal remedy and dietary spice turmeric. It is used by different folks for treatment of many diseases. Recent studies have discussed poor bioavailability of curcumin because of poor absorption, rapid metabolism, and rapid systemic elimination. Nanotechnology is an emerging field that is potentially changing the way we can treat...

The traditional mode of encapsulating drugs in liposomes poses risks to drug stability, especially when recognition agents are attached to the liposomal surface to obtain targeted liposomes. To reduce such risks, we devised a simple, novel method to entrap drugs in liposomes, consisting of (i) preparation and lyophilization of drug-free regular and surface-modified liposomes and (ii) drug encap...

(DDC)2Zn, disulfiram (DS) metabolite, has shown promisinganticancer effects in vitro but further investigations vivo are limited by itspoor water solubility. In this study, liposomes assessed as a deliverysystem for (DDC)2Zn. Liposomes were prepared the thin-filmhydration method, followed high-pressure homogenisation (HPH) sizereduction. The nano-liposomes then characterised size, polydispersit...

The antioxidant and antimicrobial activity of methanol or dichloromethane extracts of O. dictamnus, produced from wild and organic cultivated specimens, were determined. The Rancimat and malondialdehyde (MDA) by HPLC methods were used to measure the antioxidant action, in comparison with that of the common commercial antioxidants butylated hydroxytoluene (BHT) and alpha-tocopherol. The extracts...

The greatest obstacle to clinical application of cancer gene therapy is lack of effective delivery tools. Gene delivery vehicles must protect against degradation, avoid immunogenic effects and prevent off target delivery which can cause harmful side effects. PEGylated liposomes have greatly improved tumor localization of small molecule drugs and are a promising tool for nucleic acid delivery as...

Liposomal encapsulation is known to signifi cantly improve the therapeutic index of a drug. In the present investigation liposomal formulations were chosen to transport clindamycin, which is considered as the most effective topical antibiotic for acne, into the skin layers. Liposomes with clindamycin phosphate were prepared using lipid fi lm hydration method and the optimum ratio of the compone...

The purpose of the present investigation was to determine the feasibility of using lysolipid-based thermal sensitive liposomes (145nm) for high molecular weight molecule delivery. Fluorescein isothiocyanate conjugate-albumin was used as a model drug (MW 66kDa). Thermal sensitive liposomes, which encapsulated the protein were prepared using a passive encapsulation methodology involving freeze-th...

This study reports on L-carnosine phytosomes as an alternative for the prodrug N-acetyl-L-carnosine as a novel delivery system to the lens. L-carnosine was loaded into lipid-based phytosomes and hyaluronic acid (HA)-dispersed phytosomes. L-carnosine-phospholipid complexes (PC) of different molar ratios, 1:1 and 1:2, were prepared by the solvent evaporation method. These complexes were character...

Intranasal route is one of the most attractive routes for distributing drugs to systemic circulation. Liposomes are used as biocompatible carriers to improve delivery properties across nasal mucosa. The objective of the present study was to formulate acyclovir liposomes and partition into poly-N-vinyl-2-pyrrolidone. Entrapment efficiency showed that multilamellar and unilamellar liposomes were ...
