Cobra venom phospholipase A2 inhibition by manoalide. A novel type of phospholipase inhibitor.
Manoalide, an unusual nonsteroidal sesterterpenoid recently isolated from sponge, antagonizes phorbol-induced inflammation but not that induced by arachidonic acid, suggesting that manoalide acts prior to the cyclooxygenase step in prostaglandin synthesis, possibly by inhibiting phospholipase A2. We have now studied the inhibitory effect of manoalide on a homogeneous preparation of phospholipas...

15 صفحه اولChemical modification of aldehyde dehydrogenase by a vinyl ketone analogue of an insect pheromone.
A major component of the sex pheromone from the tobacco budworm moth Heliothis virescens is a C16 straight-chain aldehyde with a single unsaturation at the eleventh position. The sex pheromones are inactivated when metabolized to their corresponding acids by insect aldehyde dehydrogenase. During this investigation it was demonstrated that the C16 aldehyde is a good substrate for human aldehyde ...
متن کاملSerum phospholipases A2 in inflammatory diseases.
Phospholipase A2 (EC 3.1.1.4; PLA2) is detected in serum by determination of either the catalytic activity of the enzyme or the concentration of the enzyme protein by immunoassays. The most sensitive methods for determining PLA2 catalytic activity are radiometric assays, with a substrate of synthetic phospholipid (e.g., phosphatidylcholine or phosphatidylethanolamine) containing a 14C- or 3H-la...
متن کاملSerum phospholipases A2 after aortobifemoral reconstruction.
Phospholipase A2 has been implicated in the pathogenesis of local and distant tissue injury after ischaemia and reperfusion. A common operation inducing ischaemia and reperfusion is aortobifemoral reconstruction, during which the aorta is clamped and the blood supply via the inferior mesenteric artery and iliac arteries is interrupted. The purpose of the present work was to study the catalytic ...
