Abstract

Dimeric β-carbolines are cytotoxic against multiple NSCLC cell lines, and we report herein our preliminary studies on the mechanism of action of these dimeric structures. Dimeric β-carboline 1, which is more potent than the corresponding monomer in NSCLC cell lines, is a lysosomotropic agent that inhibits Autophagy and mediates cell death by Apoptosis, upregulating the pro-apoptotic BH3-only protein PUMA (p53 upregulated modulator of Apoptosis) in a dose dependent manner.
