HAMI 3379 is a potent and selective CysLT₂ receptor antagonist. HAMI 3379 has a protective effect on acute and subacute ischemic brain injury, and attenuates microglia-related inflammation.

In a CysLT₂ receptor reporter cell line, HAMI3379 antagonizes leukotriene D₄- (LTD₄-) and leukotriene C₄- (LTC₄-) induced intracellular calcium mobilization with IC₅₀ values of 3.8 nM and 4.4 nM respectively. HAMI3379 exhibits very low potency on a recombinant CysLT₁ receptor cell line (IC₅₀>10000 nM). HAMI3379 does not exhibit any agonistic activity on both CysLT receptor cell lines.

HAMI 3379 (0.025-0.4 mg/kg; ip) with 0.1-0.4 mg/kg significantly reduces the infarct volume and percentage increase in the ischemic/contralateral hemispheric ratio.
HAMI3379 (0.1 mg/kg; ip) administered at 0 and 1 h after reperfusion reduces infarct volume, attenuated brain edema, reduced neurological score, and increased holdingangle.
