In our work, as a preliminary experiment, the N-phenacylisoquinolinium bromide was reacted with methlhydrazine in refluxed acetic acid. Unexpectedly, 2-methyl-1,2,3-triazole was obtained. The further study of this reaction led to a more simple starting material,α-bromoacetophenone to react with methylhydrazine, obtaining the same product.

我们在研究N-苯乙酰异喹啉溴化物与甲肼在冰醋酸中的反应时，意外地得到了2-甲基-4-苯基-1，2，3-三氮唑，经过进一步的研究发现α-溴代苯乙酮与甲肼也能得到同样的产物。

Methods: Eleven B-CLL patients were studied. Leukemic lymphocytes with (n=8) or without (n=3) P2z receptors were exposed in vitro to ATP, benzoylbenzoic-ATP, 2-methylthio-ATP(2MeSATP), adenosine-5′-［γ-thio］ triphosphate, and other nucleosides for 8h. Apoptosis was detected by electron microscopy, agarose gel electrophoresis, and quantitative TdT assay. Results:Apoptosis was detected only in leukemic lymphocytes with P2z receptors. By using the quantitative assay, ATP-inducing DNA strand breaks were found to occur specifically for BzATP, ATP and 2MeSATP, but not for ATP-γS and other nucleosides.

In the third chapter, eight new complexes of 4, 6-dimethylpyrimidine 2-thioacetic acid with rare earth metals has been synthesized and characterized by means of elemental analysis, molar conductivity, IR,〓 NMR and TG-DTA. The general formula of the complexes is Ln〓(n=4 or 5). In the complexes, the deprotonated ligand coordinated to the rare earth metal ions in chelate bidentate mode. 4 or 5 molecular of crystal water existed in the complexes.

第三章合成了八种4，6-二甲基嘧啶-2-硫代乙酸的稀土配合物，通过元素分析、摩尔电导、红外光谱、核磁共振氢谱和热重-差热对配合物进行了表征，研究结果表明，配合物的组成为Ln〓n=4或5），在配合物中配体羧基脱去质子后采用螯合双齿的方式与稀土离子形成配位键，同时，配合物中含有4或5个结晶水。
