生物活性:
Tegaserod is an orally active serotonin receptor 4 (HTR4; 5-HT4R) agonist and a 5-HT2B receptor antagonist. Tegaserod has pKis of 7.5, 8.4 and 7.0 for human recombinant 5-HT2A, 5-HT2B and 5-HT2C receptors, respectively. Tegaserod causes tumor cell apoptosis, blunts PI3K/Akt/mTOR signaling and decreases S6 phosphorylation. Tegaserod has anti-tumor activity and has the potential for irritable bowel syndrome (IBS) research.
体内研究:
替加色罗 (5 mg/kg/天; 腹腔注射; 连续五天) 在体内延迟肿瘤生长、减少转移、增加存活率并抑制 p-S6。替加色罗 (0.1-2.0 mg/kg; 胃负荷前 15 分钟腹腔注射) 显着加速 db/db 小鼠的胃葡萄糖排空率,在 0.1mg/kg 的情况下将 30 分钟时留在胃中的膳食部分减少 80%.Animal Model:C57BL/6?J mice were subcutaneously injected with B16F10 cells
Dosage:5?mg/kg
Administration:Administered intraperitoneally (i.p.) daily for five consecutive days
Result:Treatment significantly decreased tumor growth and resulted in only slight decreases in weight following treatment.
Animal Model:Female C57BLKS/J db/db mice
Dosage:0.1, 0.5, 1.0, 2.0 mg/kg
Administration:IP 15 min prior to gastric loading
Result:Produced a dramatic decrease in the fraction of the meal remaining in the stomach for doses as low as 0.1 mg/kg (0.1 mg/kg).Accelerated gastric emptying, with a reduction of nearly 80% in the fraction remaining at 30 min (P < 0.0001) (0.1 mg/kg).Induced a significant decrease in the gastric emptying rate as the amount of the meal remaining at 30 min was significantly greater (2.0 mg/kg).Resulted in inhibition of tegaserod-induced increased gastric emptying (0.1 mg/kg).
体外研究:
替加色罗 (3-5 μM; 24-72 小时) 引起显着的时间和剂量依赖性细胞凋亡增加。替加色罗 (3-5 μM; 8-18 小时) 降低 p-S6 ,p-p70 S6 (Thr421/Ser424)。替加色罗 (0.1-3 μM; 24 小时) 有效抑制 5-HT 介导的大鼠离体胃底收缩 (pA2=8.3),与 5-HT2B 受体拮抗剂活性一致。
