Trimethoxybenzanilide-Based P-Glycoprotein Modulators: An Interesting Case of Lipophilicity Tuning by Intramolecular Hydrogen Bonding
JOURNAL OF MEDICINAL CHEMISTRY, 57:6403-6418, AUG 14 2014
One of the principal reasons for the chemotherapy failure is the overexpression of drug efflux pumps, ABCB1 (also known as MDR1 or P-gp) and ABCC1 (also known as MRPI), whose inhibition remains a priority to circumvent drug resistance. We have recently shown a clear trend between lipophilicity and P-glycoprotein inhibitory activity for a class of galloyl-based modulators targeting P-glycoprotein and MRP1. Herein we report a new series of polymethoxy benzamides, whose lipophilicity was modulated through the establishment of an intramolecular hydrogen bond (IMHB) which allows reaching of P-gp inhibitory activity at the submicromolar IC50 level. The present study provides a strong rationale for candidates in the presence of IMHB as a key element for a high P-gp inhibitory activity.
