Effect of long-chain alkylamines on arachidonate metabolism in macrophages. 1991

P Dieter, and E Fitzke

Biochemisches Institut, Universität Freiburg.

The two long-chain alkylamines RO 31-4493 and RO 31-4639 inhibit in a concentration-dependent manner the zymosan-induced release of arachidonic acid, the conversion of arachidonic acid into thromboxane, prostaglandin E2 and D2 and the uptake and incorporation of exogenously added arachidonate into membrane lipids of liver macrophages. The generation of superoxide and the formation of inositol phosphates is not influenced by both agents. These results suggest a rather specific interaction of RO 31-4493 and RO 31-4639 with enzymes involved in the cellular metabolism of arachidonic acid.

D007295	Inositol Phosphates	Phosphoric acid esters of inositol. They include mono- and polyphosphoric acid esters, with the exception of inositol hexaphosphate which is PHYTIC ACID.	Inositol Phosphate,Phosphate, Inositol,Phosphates, Inositol
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.
