| Bioactivity | CM121 is an active site-directed reversible ALDH1A2 inhibitor (IC50=0.54 μM；Kd=1.1 μM) with a variety of hydrophobic interactions[1]. |
| Target | IC50: 0.54 μM (ALDH1A2), Kd: 1.1 μM (ALDH1A2) |
| Invitro | CM121 interacts with the main-chain amides of Cys320 and Thr321 and the side-chains of Thr321 and Asn187 via methylsulfonyl oxygen. CM121 establishes π-π stacking with the side chains of PHE188 and PHE314 through methylsulfonyl benzene and benzylonitrile rings[1]. |
