Replaces Prod. #: ALX-350-045

Marine sesterterpenoid. Irreversibly inhibits human synovial phospholipase A2 (PLA2, IC50=0.02-0.2µM depending on substrate) as well as bee (IC50=0.05µM) and cobra venom (IC50=2µM) PLA2 by covalently modifying lysine residues. Inhibits human recombinant sPLA2 (IC50=4.7µM) selectively over cPLA2. Also inhibits phospholipase C (PLC, IC50=1.5µM) and Ca2+ channels. Inhibits superoxide generation in polymorphonuclear leukocytes. Inhibits the release of arachidonate in cultured mouse peritoneal macrophages and in a mouse in vivo model. Has anti-inflammatory and analgesic properties. Shows strong quorum sensing antagonism.
