Abstract

Inhibitory effects of 16 cinnamic acid analogs on formyl-Met-Leu-Phe(fMLP)-induced chemotaxis of rat polymorphonuclear leukocytes were determined by using a microchemotaxis appa ratus. 3,4-Dlhydrocinnamic acid called as caffeic acid exhibited the highest inhibitory effect on the chemotaxis among cinnamic acid analogs tested in this study. Hydroxycinnamic acids exhibited stronger inhibitory effects on the chemotaxis than cinnnamic acid. Hydroxycinnamic acids with one hydroxy group at ortho, meta or para position exhibited similar inhibitory effects on the chemotaxis with corresponding methoxy cinnamic acids, but 3,4-dihydroxycinnamic acid did stronger inhibitory effects than 3,4-dimethoxycinnamic acid. 3,4-Dimethoxycinnamic acid exhibited weaker inhibitory effects on the chemotaxis than 1,2-dimethoxy-4-propenylbenzene and 3,4-dimethoxy cinnamonitrile with -CH=CHCN or -CH=$CHCH_3$, group instead of -CH=CHCOOH group. 4-Hydroxy cinnamic acid and 3,4-dihydroxycinnamic acid exhibited stronger exhibitory effects on the chemotaxis than 3-(4-hydroxyphenyl) propionic acid and 3,4-dihydroxyhydrocinnamic acid with -$CH_2CH_2$COOH group instead of -CH=CHCOOH group.
