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

In Vitro	Quipazine dimaleate 对 5-HT1 和 5-HT2 具有结合效能，Ki 值均为 230 nM[3]。 Quipazine dimaleate 取代大鼠内皮层中 5-HT3R 的 [3H]GR65630，Ki 值为 1.4 nM[3]。 Quipazine dimaleate 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 dimaleate (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]。 Animal Model: Male and female Wistar rats feed with different sources of the three macronutrients (Group 1: casein, corn starch, safflower oil. Group 2: egg protein, corn starch/sucrose, lard. Group S: casein hydrolysate, maltose dextrin, butter.)[1] Dosage: 2.5, 5 and 7.5 mg/kg Administration: Intraperitoneal injection; 2.5, 5 and 7.5 mg/kg, one dose for once Result: Increased water intake and food intake of male rats from Group S, and reduced food intake of female rats from Group 1 and Group 2s at 2h post-injection. Reduced food intake in female rats from Group 2, reduced protein intake in female rats from Group 1.
