Pizotyline-d₃  (Synonyms: 苯噻啶-d₃; Pizotyline-d₃; BC-105-d₃)

Pizotyline-d₃ is deuterated labeled Pizotifen (HY-B0115). Pizotifen (Pizotyline) is a potent 5-HT₂ receptor antagonist, with a high affinity for 5-HT_1C binding site.

氢、碳和其他元素的稳定重同位素已被纳入药物分子中，主要作为药物开发过程中定量的示踪剂。氘化引起了人们的关注，因为它可能影响药物的药代动力学和代谢谱^[1]。

The weights of the fetuses are significantly reduced by all administered doses of Pipethiadene and Pizotifen (BC-105); the weights of the placentas are significantly reduced after 0.6 and 1.2 mg/kg Pipethiadene and only after the middle dose of Pizotifen. The means of the implantations, live, dead fetuses, resorptions and the occurrence of external, skeletal and visceral anomalies do not differ from the control group. The number of chromosome aberrations in the bone marrow cells of treated mice does not differ significantly from the negative control group. The micronucleus test reveals no elevation in the frequency of micronuclei as compared to the control group. After the two higher doses of both Pipethiadene and Pizotifen (BC-105) maleate, the mitotic indices are lower than in the control group^[4].
