8-CSC is a dual agent endowed with good hMAO-B inhibitory activity (Ki: 235 nM in baboon liver mitochondria) and A2A affinity (Ki: 36 nM in rat brain striatal membranes receptor).
In platinum-resistant A2780cis human ovarian cancer cells, thioxodihydroquinazolinone-19 is an inducer of apoptotic cell death. It acts by exhibiting a strong inhibitory effect in ovarian CSC-LCs in combination with cisplatin.
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.
