Detergents as intrinsic P-glycoprotein substrates and inhibitors

Design, synthesis, and biological evaluation of 6-methoxy-2-arylquinolines as potential P-glycoprotein inhibitors

Objective(s): In the present study,a new series of 6-methoxy-2-arylquinoline analogues was designed and synthesized as P-glycoprotein (P-gp) inhibitors using quinine and flavones as the lead compounds. Materials and Methods: The cytotoxic activity of the synthesized compounds was evaluated against two human cancer cell lines including EPG85-257RDB, multidrug-resistant gastric carcinoma cells (P...

Rapid identification of P-glycoprotein substrates and inhibitors.

Identifying molecules that interact with P-glycoprotein (P-gp) is important for drug discovery but is also generally reliant on time-consuming in vitro and in vivo studies. As an alternative approach, the current study applied pharmacophore models and database screening to rapidly retrieve molecules that bind as substrates or inhibitors for P-gp from commercial databases and then confirmed thei...

Computational models for predicting substrates or inhibitors of P-glycoprotein.

The impact of P-glycoprotein (P-gp) on the multidrug resistance and pharmacokinetics of clinically important drugs has been widely recognized. Here, we review in silico approaches and computational models for identifying substrates or inhibitors of P-gp. The advances in the datasets for model building and available computational models are summarized and the advantages and drawbacks of these mo...

Characterization of the major metabolites of verapamil as substrates and inhibitors of P-glycoprotein.

Verapamil is subject to extensive oxidative metabolism mediated by cytochrome P450 enzymes with less than 5% of an oral dose being excreted unchanged in urine. Furthermore, verapamil is known to be a potent inhibitor of P-glycoprotein function. There is evidence from in vivo investigations that some verapamil metabolites might be actively transported. The aim of the present study was to investi...
