Abstract

Synthesis and in vitro cytotoxicity assays of new anthranilamide MDR modulators have been performed to assess their inhibition potency of the P-glycoprotein (P-gp) transporter. The aromatic spacer group between nitrogen atoms (N1 and N2) in the known inhibitor XR9576 was replaced with a flexible alkyl chain of 2 to 6 carbon atoms in length. 6, 7-Dimethoxy-1, 2, 3, 4-tetrahydroisoquinoline and their open-chain N-methylhomoveratrylamine ...
