Perenosins: A new class of anion transporter with anti-cancer activity

Abstract

A new class of anion transporter named 'perenosins' consisting of a pyrrole linked through an imine to either an indole, benzimidazole or indazole is reported. The indole containing members of the perenosin family function as effective transmembrane Cl-/NO3- antiporters and HCl cotransporters in a manner similar to the prodigiosenes. The compounds reduce the viability of MDA-MB-231 and MCF-7.
