• 靶点:

  5-HT2A Receptor

  5-HT1C Receptor

• 体外研究: Pizotifen是一种有效的5-HT2受体拮抗剂,对5-HT1C结合位点具有高亲和力[1]。 Pizotifen是一种抗过敏的5-HT2A受体拮抗剂,具有抑制5-羟色胺增强的ADP诱导的血小板聚集的能力[2]。
• 体内研究: 所有给药剂量的Pipethiadene和Pizotifen malate都显着降低了胎儿的体重;在0.6和1.2 mg/kg Pipethiadene之后,并且仅在中等剂量的Pizotifen苹果酸盐后,胎盘的重量显着减少。植入,活体,死胎,再吸收以及外部,骨骼和内脏异常的发生方式与对照组没有差异。处理小鼠的骨髓细胞中的染色体畸变数与阴性对照组没有显着差异。与对照组相比,微核试验显示微核的频率没有升高。在两种较高剂量的Pipethiadene和Pizotifen马来酸盐后,有丝分裂指数低于对照组[3]。
• 动物实验: 从妊娠第4天至第16天，以0.24,0.6和1.2mg / kg的剂量将小鼠[3]苹果酸马替替尼口服给予三组瑞士小鼠。对照组用蒸馏水处理。在妊娠第19天，处死小鼠并测定细胞遗传学检查和子宫内容物（活胎，异常和死胎的数量以及植入，再吸收的数量）。检查活体胎儿的外部，内脏和骨骼畸形[3]。
