Abstract:
Leukotriene (LT) synthesis triggered with ionophore A23187 or inflammatory stimuli (PAF, fMLP) in human polymorphonuclear leukocytes (PMNL) was markedly decreased by SIN-1, an active metabolite of molsidomine. This inhibition occurred in the absence or in the presence of exogenous arachidonic acid (AA). These results suggest that SIN-1 inhibited both the release of AA from membrane phospholipids and the 5-lipoxygenase activity in human PMNL. Molsidomine was without any effect on LT formation.
