Biological Activity

[Description]:

Quipazine is a 5-HT agonist with a Ki value of 1.4 nM for displaces [3H]GR65630 from 5-HT3R in rat. Quipazine shows antiviral activity against SARS-CoV-2 with an EC50 of 31.64 μM. Quipazine behaves as a 5-HT3R agonist in peripheral models. Quipazine can be used for neurological disease research[1][2][3][4].

[In Vitro]

Quipazine 对 5-HT1 和 5-HT2 具有结合效能，Ki 值均为 230 nM[3]。 Quipazine 取代大鼠内皮层中 5-HT3R 的 [3H]GR65630，Ki 值为 1.4 nM[3]。 Quipazine 对大鼠迷走神经具有拮抗作用，对 5-HT2，5-HT1 以及抑制 5-HT 释放的 pIC50 值分别为 6.1，6.49 和 6.17[4]。

[In Vivo]

Quipazine (2.5，5 和 7.5 mg/kg，每个剂量各一次；腹腔注射) 影响雄性和雌性大鼠对不同宏量营养素饮食的膳食自我选择[1]。
