| Description | CM121 is a reversible inhibitor of ALDH1A2 that acts specifically on the active site, exhibiting an IC50 of 0.54 μM and a Kd of 1.1 μM. It exerts its inhibitory effect through multiple hydrophobic interactions. |
| Targets&IC50 | ALDH1A2:0.54 μM (IC50), ALDH1A2:Kd: 1.1 μM |
| In vitro | CM121 engages with the main-chain amides of Cys320 and Thr321, as well as the side-chains of Thr321 and Asn187, through its methylsulfonyl oxygen. Moreover, CM121 forms π-π stacking interactions with the side chains of PHE188 and PHE314 via its methylsulfonyl benzene and benzylonitrile rings[1]. |
