ARM1 Chemical Properties,Usage,Production

Description

Leukotriene A₄ (LTA₄) hydrolase/aminopeptidase is a bifunctional zinc metalloenzyme that both catalyzes the synthesis of LTB₄ from LTA₄ and cleaves the chemotactic peptide Pro-Gly-Pro. ARM1 is a thiazolamine that inhibits LTB₄ synthesis in human neutrophils (IC₅₀ = ~0.5 μM) and conversion of LTA₄ to LTB₄ by purified LTA₄ hydrolase (K_i = 2.3 μM). ARM1 does not significantly affect the hydrolysis of Pro-Gly-Pro by LTA₄ hydrolase.
