Approaches to minimize the effects of P-glycoprotein in drug transport: A review.

P-glycoprotein (P-gp) is a transporter protein that is come under the ATP binding cassette family of proteins. It is situated on the surface of the intestine epithelium, where P-gp substrate binds to the transporter and is pumped into the intestine lumen by the ATP-driven energy-dependent process. In this review, we summarize the role of the P-gp efflux transporter situated on the intestine, the clinical importance of P-gp related drug interactions, and approaches to minimize the effect of P-gp in drug transport.

Determination of permeability, plasma protein binding, blood partitioning, pharmacokinetics and tissue distribution of Withanolide A in rats: A neuroprotective steroidal lactone.

Preclinical Research & Development Withanolide A (WA), a steroidal lactone is a major bioactive constituent of Withania somnifera (L.) with remarkable neuropharmacological activity. In this study, we investigated the permeability, plasma protein binding (PPB), blood partitioning, intravenous (i.

A Novel Benzocoumarin-Stilbene Hybrid as a DNA ligase I inhibitor with in vitro and in vivo anti-tumor activity in breast cancer models.

Existing cancer therapies are often associated with drug resistance and toxicity, which results in poor prognosis and recurrence of cancer. This necessitates the identification and development of novel therapeutics against existing as well as novel cellular targets. In this study, a novel class of Benzocoumarin-Stilbene hybrid molecules were synthesized and evaluated for their antiproliferative activity against various cancer cell lines followed by in vivo antitumor activity in a mouse model of cancer.

Preparation and in-vitro/in-vivo characterization of trans-resveratrol nanocrystals for oral administration.

Trans -resveratrol (t-RES) is a natural polyphenolic compound with extensive therapeutic activities; however, its clinical application is circumscribed due to its poor solubility and low bioavailability. The purpose of this study was to prepare stable t-RES nanocrystals (t-RES-NCs) with different stabilizers to improve its oral bioavailability. t-RES-NCs were fabricated by the probe sonication method and optimized by particles size, poly dispersive index and zeta potential.
