We have synthesized five new cholesterol based gemini cationic lipids possessing hydroxyethyl (-CH(2)CH(2)OH) function on each head group, which differ in the length of the polymethylene spacer chain. These gemini lipids are important for gene delivery processes as they possess pre-optimized molecular features, e.g., cholesterol backbone, ether linkage and a variable spacer chain between both t...

A simple, specific, accurate, precise and reproducible method has been developed and validated for the estimation of Dithranol in lipid nanoparticle by RP-HPLC method. RP-HPLC estimation of dithranol in prepared formulation was performed using Phenomenex ODS 5μ, C18 column and Acetonitrile: Methanol: Buffer (20:20:60) as mobile phase which had shown sharp peak when detected at 258 nm. The linea...

Development of lipid-based adjuvant formulations to enhance the immunogenicity of recombinant vaccine antigens is a focus of modern vaccine research. Characterizing interactions between vaccine antigens and formulation excipients is important for establishing compatibility between the different components and optimizing vaccine stability and potency. Cryogenic transmission electron microscopy (...

Risperidone (RISP) is an antipsychotic agent and has low water solubility and nontargeted delivery results in numerous side effects. Hence, an attempt was made to develop SLNs hydrogel for intranasal delivery of RISP to achieve maximum bioavailability and reduction of side effects. RISP loaded SLNs composed of 1.65% (w/v) lipid mass were produced by high shear homogenization (HSH) coupled ultra...

INTRODUCTION Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response. Poor aqueous solubility of lipophilic drugs creates problems in formulation as well as in oral administration. Various approaches have been developed to resolve poor aqueous solubility of lipophilic drugs. As oral route for drug administration ...

KW-3902 (a newly synthesized adenosine A(1)-receptor antagonist) has potent diuretic and renal protective activities and was formulated in lipid dispersion systems, i.e., lipid emulsions and liposomes. The objective of the present study was to evaluate the carrier potential of these lipid dispersion systems, which is explained here as the ability of the formulation to retain the drug in its dis...

Current approaches to encapsulate and deliver therapeutic compounds have focused on developing liposomal and biodegradable polymeric nanoparticles (NPs), resulting in clinically approved therapeutics such as Doxil/Caelyx and Genexol-PM, respectively. Our group recently reported the development of biodegradable core-shell NP systems that combined the beneficial properties of liposomal and polyme...

Administration of drug by oral route is the most effective and acceptable route as it has better therapeutic efficacy, low cost and good patient compliance. More than 40% of new drugs are poorly water soluble. These drugs present development challenges and also have poor bioavailability. Although many formulation approaches like solid dispersions, complexation, pH modification exist, novel lipi...
