Descripción

Descripción general

A cell-permeable benzylphenyl-thiazolamine compound that selectively inhibits against the leukotriene (LT) A₄ epoxide hydrolase activity of LTA4H by occupying the same hydrophobic tunnel (K_i = 2.3 µM) targeted by LTA₄ ω-end, displaying much reduced potency against LTA4H aminopeptidase activity (% inhibition/[ARM1] = 0/100 µM & 35/1 mM; Substrate = 800 µM Pro-Gly-Pro) coordinated by E296 and the catalytic site Zn²⁺ at the adjacent hydrophilic peptide substrate-binding cavity. Shown to inhibit A23187- (Cat. Nos. 100105 & 100106) induced LTB₄ production in primary human polymorphonuclear neutrophil (PMN) cultures (IC₅₀ = 0.5 µM; ARM1 added 10 min prior to 5 min stimulation by 2.5 µM A23187). Another LTA4H inhibitor SC 57461A (CAS 423169-68-0), in comparison, inhibits both the LTA₄-to-LTB₄ conversion as well as the chemotactic tripeptide Pro-Gly-Pro degradation activity of LTA4H.
