Nanoparticle Engineering of Aprepitant Using Nano-by-Design (NbD) Approach.

The aim of this research was to develop a nanosuspension of aprepitant (APT) using the Nano-by-Design approach. A novel microfluidization technology was used for processing the formulation. A 3 full factorial design was used for the optimization of dependent variables, which included critical quality attributes like particle size and polydispersity index.

Evaluation of Phytopolyphenols for their gp120-CD4 Binding Inhibitory Properties by In Silico Molecular Modelling & In Vitro Cell Line Studies.

Background: Lack of effective early-stage HIV-1 inhibitor instigated the need for screening of novel gp120-CD4 binding inhibitor. Polyphenols, a secondary metabolite derived from natural sources are reported to have broad spectrum HIV-1 inhibitory activity. However, the gp120-CD4 binding inhibitory activity of polyphenols has not been analysed in silico yet.

Preparation and Characterization of Solid Lipid Nanoparticles-Based Gel for Topical Delivery.

Solid lipid nanoparticles (SLNs) have been extensively investigated for effective delivery of both hydrophilic and lipophilic drugs by topical route. There are several scalable techniques for the preparation of SLNs such as homogenization, microemulsion template, and solvent emulsification diffusion. This chapter describes step-wise methodology for the preparation and characterization of SLNs using solvent emulsification diffusion method.

Tetrahydrocurcumin-loaded vaginal nanomicrobicide for prophylaxis of HIV/AIDS: in silico study, formulation development, and in vitro evaluation.

A vaginal microbicide is a front-line women-dependent approach and an alternative to a condom for prevention of unprotected sexual intercourse-associated HIV. The microbicide research is still in its infancy with several products in the clinical studies being reported to have good efficacy, safe, but with poor adherence. One such molecule reported with an excellent efficacy when tested preclinically is curcumin, a natural polyphenol derived from Curcuma longa.
