An amphotericin B-containing (AmB) solid lipid nanoparticulate drug delivery system intended for oral administration, comprised of bee's wax and theobroma oil as lipid components was formulated with the aim to ascertain the location of AmB within the lipid matrix: (a) a homogenous matrix; (b) a drug-enriched shell; or (c) a drug enriched core. Both the drug-loaded and drug-free nanoparticles we...

The aim of this study was to prepare liposomes of acyclovir (ACY) by thin layer evaporation (TLE) and reverse phase evaporation (REV) methods. Twenty-seven batches of liposomes from each method were prepared using technique of three variables at three levels (33) factorial design. Drug/Lipid (molar ratio), hydration volume and hydration time were considered three independent variables in TLE me...

A hybrid computational approach based on molecular dynamics simulations and deep learning algorithms facilitate fast accurate estimation of the free energy permeation small drug-like molecules across lipid bilayers.

Solid lipid nanoparticles are at the forefront of the rapidly developing field of nanotechnology with several potential applications in drug delivery, research and clinical medicine, as well as in other varied sciences. Solid lipid nanoparticle (SLN) dispersions have been proposed as a new type of colloidal drug carrier system suitable for intravenous administration. Solid lipid nanoparticles (...

Abstract The lipid-based colloidal carriers, such as nanostructured lipid carriers (NLCs), solid nanoparticles (SLNs), nanocapsules, liposomes, and microemulsion, are the latest significant entrants in development of drug delivery systems owing to their myriad advantages. NLCs second-generation SLNs having unstructured matrix, have high loading, provide long-term stability comparison other syst...

Studies from this laboratory (Mayer et al. (1986) Biochim. Biophys. Acta 857, 123-126) have shown that doxorubicin can be accumulated into liposomal systems in response to transmembrane pH gradients (inside acidic). Here, detailed characterizations of the drug uptake and retention properties of these systems are performed. It is shown that for egg phosphatidylcholine (EPC) vesicles (mean diamet...

the study was designed with an aim to evaluate the protective effects of reduced glutathione on cyclophosphamide induced lipid peroxidation and also changes in cholesterol content. goat liver and white new zealand rabbit were used as lipid source for the models. lipid peroxidation study was performed by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide con...

Lipidic prodrugs, also called drug-lipid conjugates, have the drug covalently bound to a lipid moiety, such as a fatty acid, a diglyceride or a phosphoglyceride. Drug-lipid conjugates have been prepared in order to take advantage of the metabolic pathways of lipid biochemistry, allowing organs to be targeted or delivery problems to be overcome. Endogenous proteins taking up fatty acids from the...
