MedKoo CAT#: 574075

CAS#: 109437-62-9

Description: 673-A is an aldehyde dehydrogenase (ALDH1A) inhibitor that depletes CD133+ cancer stem cells (CSC) in ovarian cancer cell lines. 673-A triggers necroptosis in ovarian CSCs and induces expression of mitochondrial uncoupling proteins (UCP). 673-A also overcomes chemotherapy resistance in vivo.
