NCT-505 free base

Research use only, not for human use.

NCT-505 free base (NCT505) is a potent, selective, orally available ALDH1A1 inhibitor with IC50 of 7 nM (hALDH1A1).

NCT-505 free base (NCT505) is a potent, selective, orally available ALDH1A1 inhibitor with IC50 of 7 nM (hALDH1A1), exhibits high specificity over other ALDH isozymes and unrelated dehydrogenases; also exhibits IC50 of 30 nM in MIA PaCa-2 Aldefluor cell-based assays; demonstrates target engagement in CETSA asssay (EC50=3.4 uM), inhibits the formation of 3D spheroid cultures of OV-90 cancer cells, and potentiates the cytotoxicity of Paclitaxel in SKOV-3-TR, a Paclitaxel resistant ovarian cancer cell line.

NCT-505 (Compound 86) is a potent and selective aldehyde dehydrogenase (ALDH1A1) inhibitor, with an IC50 of 7 nM, and weakly inhibits hALDH1A2, hALDH1A3, hALDH2, hALDH3A1 (IC50s, >57, 22.8, 20.1, >57 μM). NCT-505 has no obvious inhibitory effec on 5-hydroxyprostaglandin dehydrogenase (HPGD) and type-4 hydroxysteroid dehydrogenase (HSD17β4) (IC50, >57 μM). Moreover, NCT-505 shows potent cellular activities, reducing the viability of OV-90 cells with an EC50 of 2.10-3.92 μM. NCT-505 is also cytotoxic to SKOV-3-TR cells, with IC50s of 1, 3, 10, 20, 30 μM, respectively, in the titration assay.
