General description

A highly hydrophobic cyclic pentapeptide that selectively binds and acts as a potent inhibitor of human type IIA secreted phospholipase A2 (sPLA2-IIA) (IC50 = 12.8 µM). Reported to effectively block sPLA2-IIA-induced PGE2 production at 100 nM in human rheumatoid synoviocytes and is non-toxic at doses up to 10 µM. Does not have any significant effect on the activities of porcine sPLA2-IB, Naja naja sPLA2-IB, or Crotalus durissus sPLA2-IIA at 10 µM.

The origin of the impaired CD4 T-cell response and immunodeficiency of HIV-infected patients is still only partially understood. We recently demonstrated that PLA2G1B phospholipase synergizes with the HIV gp41 envelope protein in HIV viremic plasma to induce large abnormal membrane
