Abstract

A series of 2,3-diarylindoles were synthesized via the Larock heteroannulation, and evaluated for their anticancer activity against A549 lung cancer cells. The most potent compound, PCNT13 with IC50=5.17 μM, caused the induction of two modes of programmed cell death, apoptosis and autophagy.

Keywords: 2,3-Diarylindole; Apoptosis; Autophagy; Lung cancer.
