| 产品描述: | SB-203186 hydrochloride is a potent, selective and competitive 5-HT4 antagonist. SB-203186 hydrochloride antagonizes the 5-HT4 receptor-mediated relaxations of the carbachol-contracted rat isolated oesophagus against 5-HT with pKB values of 10.9 (rat oesophagus), 9.5 (guinea-pig ileum), and 9.0 (human colon) respectively |
| 靶点: |
pKB: 10.9 (5-HT4 in rat oesophagus), 9.5 (5-HT4 in guinea-pig ileum), and 9.0 (5-HT4 in human colon) |
| 体外研究: |
Pretreatment with SB-203186 (10 μM) enhances the 5-HT-induced contractions of the antral strips |
| 体内研究: |
Intraduodenally administered SB-203186 (0.3-3 mg/kg) to new-born Camborough piglets produced blockade of 5-HT-evoked tachycardia which was maximal after 20 min and lasted for more than 3 h with 0.3 mg/kg. SB-203186 (0.1-3mg/kg, i.v.) surmountably antagonised 5-HT-evoked tachycardia in anaesthetized Yucatan minipigs or new-born Camborough piglets with similar potency |
