Fosinopril  (Synonyms: SQ28555 free acid)

Fosinopril (SQ28555 free acid) is the ester proagent of angiotensin-converting enzyme (ACE) inhibitor with an IC₅₀ value of 0.18 μM. Fosinopril demonstrates a non-competitive inhibition effect on ACE activity with an K_i value of 1.675 μM^[1][2].

IC50: 0.18 μM^[1]; Ki: 1.675 μM^[2]

Fosinopril (0-100μM; 30 min) partially inhibits the cosedimentation of liposomes and recombinant LPLA2^[1].
Fosinopril (250 nM) shows no inhibition of the soluble esterase activity of LPLA2^[1].
Fosinopril (0.372, 0.744, 1.116 μM) displays a non-competitive inhibition effect on ACE activity with an K_i value of 1.675 μM^[2].
