NPC26 is a small molecule mitochondrial disruptor with anti-tumor activity. NPC-26 shows significant anti-proliferative and cytotoxic effects on CRC cell lines (HCT-116, DLD-1, and HT-29). NPC26 can damage mitochondrial function, leading to the opening of the mitochondrial permeability transition pore (mPTP) and the production of reactive oxygen species , ultimately inducing cell death. NPC-26 can kill CRC cells by activating the AMP-activated protein kinase ( AMPK ) signaling pathway.
