title: [Inhibition of phorbol ester and A23187-stimulated prostaglandins synthesis in macrophages by anisodamine].
abstract: The effect of anisodamine on arachidonic acid metabolism in macrophages was studied. The results indicated that the synthesis of PGI2, TXA2 and PGF2 alpha stimulated by phorbol-12-myristate-13-acetate (PMA) and calcium ionophore A23187 was dose and time-dependently inhibited by anisodamine, and preincubation of the cells with anisodamine significantly decreased subsequent PMA and A23187-stimulated synthesis of prostaglandins. An isodamine failed to inhibit exogenous arachidonic acid-stimulated synthesis of prostaglandins. It is suggested that the site of action of anisodamine could be the phospholipase A2 reaction.
