This study was aimed to investigate the effect of 3,4 secoisopimara-4(18),7,15-trien-3-oic acid (compound 1) isolated from the aerial parts of Salvia cinnabarina, on upper gastrointestinal transit in mice in vivo. Compound 1 (10 - 100 mg/kg, i. p.) dose-dependently delayed gastrointestinal motility. Pretreatment ( i. p.) of mice with hexamethonium (10 mg/kg), naloxone (2 mg/kg), N(G)-nitro- L-arginine-methyl ester ( L-NAME) (25 mg/kg) or yohimbine (1 mg/kg) did not modify the inhibitory effect of compound 1 (50 mg/kg). However, the L-type Ca (2+) channel verapamil (5 mg/kg, i. p.) significantly reduced the antimotility effect of compound 1 (50 mg/kg). These results suggest that compound 1 inhibits gastrointestinal motility in mice. The effect could involve, at least in part, L-type Ca (2+) channels.

Abstract
This study was aimed to investigate the effect of 3,4 secoisopimara-4(18),7,15-trien-3-oic acid (compound 1) isolated from the aerial parts of Salvia cinnabarina, on upper gastrointestinal transit in mice in vivo. Compound 1 (10 - 100 mg/kg, i. p.) dose-dependently delayed gastrointestinal motility. Pretreatment ( i. p.) of mice with hexamethonium (10 mg/kg), naloxone (2 mg/kg), N(G)-nitro- L-arginine-methyl ester ( L-NAME) (25 mg/kg) or yohimbine (1 mg/kg) did not modify the inhibitory effect of compound 1 (50 mg/kg). However, the L-type Ca (2+) channel verapamil (5 mg/kg, i. p.) significantly reduced the antimotility effect of compound 1 (50 mg/kg). These results suggest that compound 1 inhibits gastrointestinal motility in mice. The effect could involve, at least in part, L-type Ca (2+) channels.File | Dimensione | Formato | |
