2-(1-Piperazinyl)pyrimidine is an antagonist of α2-adrenergic receptors (α2-ARs; pA2 = 6.8 in rat brain synaptosomes) and active metabolite of various azapirones, including buspirone.1,2,3,4 It is formed from buspirone by the cytochrome P450 (CYP) isoform CYP3A4 in human liver microsomes.5 2-(1-Piperazinyl)pyrimidine inhibits decreases in gastrointestinal transit induced by clonidine in rats (ED50 = 0.8 mg/kg).2 It increases drinking in the Vogel punished drinking task, indicating anxiolytic-like activity, in rats when administered at doses ranging from 1 to 4 mg/kg.3 2-(1-Piperazinyl)pyrimidine (0.25-1 mg/kg) also reduces the amplitude of electrically stimulated excitatory post-synaptic potentials (EPSPs) in the hippocampal CA1 region in rats, an effect that can be blocked by the serotonin (5-HT) receptor subtype 5-HT1A antagonist spiroxatrine.4 It has also been used a phosphopeptide derivatization agent.6

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。
