| Description | H3B-120 is a highly selective, competitive, and allosteric carbamoyl phosphate synthetase 1 (CPS1) inhibitor with an IC50 of 1.5 μM and a Ki of 1.4 μM, exhibiting anti-cancer activity. |
| Targets&IC50 | CPS1:1.4 μM (ki), CPS1:1.5 μM |
| In vitro | H3B-120 (25, 50, 75, 100 μM) inhibits urea production in a dose-dependent manner, although the cellular potency decreases significantly compared with enzymatic assays. The half-life of H3B-120 is only 40 min. H3B-120 has no inhibition of CPS2 activity of CAD (CPS2, aspartyl transcarbamylase, dihydroorotase). |
