| Target |
human 5-HT2B Receptor:7.1 (pKi) |
| In Vitro | The most selective 5-HT2B receptor ligand to be tested is SB 204741 with approximately 20 fold selectivity for the human 5-HT2B receptor as compared to the human 5-HT2C receptor[1]. |
| In Vivo | SB-204741 (0.25~1.0 mg/kg; i.p.) induces myocardial remodeling and dose dependently improves hemodynamic and ventricular functions following isoproterenol-induced myocardial injury[1]. SB-204741 bolsters endogenous anti-oxidant enzymes activities, improves cardiac injury markers, NO level and lipid peroxidation level and attenuates TNFα level in isoproterenol-induced myocardial remodeling in rats. SB-204741 (0.5 and 1.0 mg/kg/day) pre-treatment for 28 days significantly amplifies NO level and GSH and SOD activities and attenuates TBARS level following isoproterenol-induced myocardial remodeling. SB-204741 inhibits inflammatory protein expression, upregulates autophagy and HSPs protein expressions in isoproterenol-induced myocardial remodeling in rats. SB-204741 improves myocardial architecture in isoproterenol-induced myocardial remodeling in rats[1]. Animal Model: Rats[1] Dosage: 0.25~1.0 mg/kg Administration: I.p. Result: Induced myocardial remodeling. |
