Relaxant Effects of Rutin on Rat Smooth Muscles
The aim of the present study was to investigate the relaxant effects of rutin on rat thoracic aorta, ileum and trachea. Rutin (1X10-7 - 6X10-3 M) caused a concentration-dependent relaxation of aortic rings precontracted with phenylephrine (PE 10-6M) while produced non-significant relaxed effect on KCl induced contraction with Log IC50’s -3.025 and -2.885 M/ml respectively. Rutin exhibited potent inhibitory effects on (ACh 10-6 M) precontracted ileum of the rat with Log IC50 -5.996 M/mL. Rutin produced more potent inhibitory effect on ACh- than KCl-induced contractions in trachea, with Log IC50’s of -4.371 and -4.301 M/mL respectively. While rutin showed more potent inhibitory effect on PE-induced contractions potently than KCl precontracted aorta with Log IC50’s was -3.025 M and -2.885 respectively. From the data obtained during the present work, it can be concluded that rutin induces concentration-dependent relaxation in rat's smooth muscle. The mechanism of the relaxation may involves via nitric oxide-guanylyl cyclase pathway for aorta and anticholinergic activity for ileum and trachea.
