MEISi-1 is a novel MEIS inhibitor (MEISi), significantly inhibiting MEIS-luciferase reporters in vitro and inducing murine (LSKCD34low cells) and human (CD34+, CD133+, and ALDHhi cells) HSC self-renewal ex vivo.
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.
