Studies on the Synthesis, Characterization and Quantum Chemistry of Carbonic Anhydrase Active Site Model Compounds {η3 - HB(3-Phpz)3ZnX} (X = Cl- ,Br- ,I- ,NO3-)
【摘要】 制备了碳酸酐酶活性中心模型化合物{η3-HB(3-Phpz)3ZnX}[Ph=苯基,pz=吡唑,X=Cl-(1),Br-(2),I-(3),NO3-(4)],通过元素分析,IR,1HNMR对其结构进行了表征.依据模型化合物2的晶体结构数据,采用量子化学 DV-Xα方法计算了2以及{η3-HB(3-Phpz)3ZnOH}模型的分子轨道、键级和原子电荷,讨论了模型化合物分子的活泼原子和活泼基团.
【Abstract】 The active site model compounds[η3 - HB(3 - Phpz)3ZnX] [X= Cl- (1) ,Br-(2), I-(3), NO3- (4) ] of the carbonic anhydrase have been prepared and characterized by elemental analysis,IR/H NMR spectrum. The molecular orbital,bond grade and the atomic charge of themodel compound 2 as well as the model [η3 - HB(3 - Phpz)3ZnOH] were calculated by DV - Xa method. According to the calculated results the active atoms and active groups in model compounds are discussed.
