Biological Activity for YM 26734

YM 26734 is a competitive inhibitor of secretory phospholipase A₂ (sPLA₂) that exhibits a broad inhibitory profile to several sPLA₂s (IC₅₀ values are 0.2, 1, 1, 1 and 3 μM for sPLA₂-X, -IIA, -IID, -V and -IIE respectively). Displays minimal activity at sPLA₂-IIF and no activity at cytosolic PLA₂, cyclooxygenase and lipoxygenase. Ameliorates local inflammatory responses in TPA-induced mouse ear edema.
