一般描述
Caution! Product contains volatile liquid. Keep product cold at all times.
Potent inhibitor of cytotoxic activity of human natural killer cells; shown to be as potent as LTB4 in stimulating human neutrophils to generate superoxides. Involved in contractile responses and acts as a potent activator of human protein kinase C. Stimulates rapid lipid remodeling and pertussis-sensitive release of arachidonic acid in polymorphonuclear leukocytes. Stimulates MAP kinases via activation of G protein-coupled receptors.

Lipoxin A4 (LXA4) was competitive with [3H]leukotriene D4 (LTD4) for specific binding to cultured rat glomerular mesangial cells. Half-maximal inhibition was obtained with 100 nM LXA4, compared with 10 nM for unlabeled LTD4. At 10 and 50 nM LXA4 induced

The lipoxygenase-derived eicosanoids leukotrienes and lipoxins are well defined regulators of hemeodynamics and leukocyte recruitment in inflammatory conditions. Here, we describe a novel bioaction of lipoxin A(4) (LXA(4)), namely inhibition of leukotriene D(4) (LTD(4))-induced human renal mesangial cell proliferation, and

Lipoxins are trihydroxytetraene metabolites derived through a double lipoxygenation of arachidonic acid. Lipoxin A4 (LXA4) was prepared by total chemical synthesis, and its capacity to modulate eosinophil migration has been evaluated. LXA4 is a weak and partial chemotactic agent; at
