H3B-616
H3B-616 is a selective carbamoyl phosphate synthetase 1 (CPS1) inhibitor with a human IC50 of 66 nM. H3B-616 binds to an allosteric pocket in the CPS1 integrating domain to exert target engagement and inhibit enzyme activity. H3B-616 can be used for the research of nonsmall cell lung cancer and gastric cancer.

H3B-616 (Compound 25) potently inhibits purified human CPS1 enzyme activity with an IC50 of 66 nM[1].
H3B-616 does not appreciably inhibit purified human CPS2 enzyme activity, with an IC50 of ≥100 μM[1].
H3B-616 (0.01-100 μM; 16 h) potently inhibits CPS1 activity (urea production) in primary human hepatocytes with an IC50 of 0.24 μM[1].
