背景

ARM1 (4-(4-benzylphenyl) thiazol-2-amine) is a LTB4 synthesis inhibitor [1].

Leukotriene A4 (LTA4) hydrolase/aminopeptidase is a bifunctional zinc metalloenzyme that catalyzes the synthesis of the proinflammatory mediator LTB4 from LTA4 and cleaves the chemotactic tripeptide Pro-Gly-Pro. LTB4 is a key lipid mediator in the innate immune response [1][2].

ARM1 is a LTB4 synthesis inhibitor. ARM1 is a thiazolamine that inhibits LTB4 synthesis and conversion of LTA4 to LTB4 by purified LTA4H with Ki value of 2.3 μM. 50- to 100-fold higher concentrations of ARM1 did not significantly affect hydrolysis of Pro-Gly-Pro by LTA4 hydrolase. In isolated human polymorphonuclear neutrophils (PMNs), ARM1 efficiently inhibited LTB4 synthesis with IC50 value of about 0.5 μM and complete inhibition at 5 μM. ARM1 inhibited the epoxide hydrolase activity of LTA4H without significantly affecting its ability to cleave Pro-Gly-Pro. In the crystal structure of LTA4H in complex with ARM1, ARM1 occupied the binding site for the ω-end of LTA4 [1].
