Abstract
Multidrug Resistance (MDR) is due to the ability of some ATPase transporters to efflux chemotherapeutic agents out from tumor cells decreasing the endocellular concentration for the pharmacological effect, causing cancer cells chemoresistance. In the present work, a set of MDR modulating agents ( MC89, MC70, PB28, IG9) able to modulate transmembrane ATP-dependent transporter, P-glycoprotein (P-gp), and also to induce inducible nitric oxide synthase (iNOS) expression in a panel of tumor cell lines are presented. All selected compounds, known as potent P-gp modulating agents, stimulated nitric oxide (NO) via iNOS in U937, Caco-2 and MCF7–Adr cell lines. The results displayed a new pharmacological strategy to revert MDR and lead to develop a new class of MDR reverting agents devoid of the limits of P-gp inhibitors third generation.
