N-Desmethylclozapine-d8 is intended for use as an internal standard for the quantification of N-desmethylclozapine by GC- or LC-MS. N-Desmethylclozapine is an active metabolite of the atypical antipsychotic clozapine .1 It was originally described as an antagonist of serotonin (5-HT) receptor subtype 5-HT2C (IC50 = 7.1 nM in rat choroid plexus) and later as an inverse agonist using human recombinant receptors.2,3 N-Desmethylclozapine is an antagonist at dopamine D4 receptors, an agonist at δ-opioid receptors, and a partial agonist at dopamine D2 and D3, M1 muscarinic acetylcholine, and 5-HT1A receptors.3,1,4 N-Desmethylclozapine (30 mg/kg) decreases exploratory locomotor activity and increases prepulse inhibiton of the acoustic startle response in mice.5

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
