Chemical Name: 1,1'-[5-[3,4-Dihydro-7-hydroxy-2-(4-hydroxyphenyl)-2H-1-benzopyran-4-yl]-2,4,6-trihydroxy-1,3-phenylene]bis-1-dodecanone

Biological Activity

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.

Technical Data
