邻苯二甲醛作为固氮酶活性中心双齿配体的研究

Effects of O-Phthalaldehyde on Nitrogenase Catalysis and Self-Assembling of Mo-Fe-S Cluster Complexes

考察了邻苯二甲醛对固氮酶催化乙炔还原及放H_2活性的影响,结果表明邻苯二甲醛是有效的固氮酶活性中心双齿螯合抑制剂,在MOS_4^(2-)-nFeCl_b-DMF自兜合成固氮酶活性中心模拟物体系中,邻苯二甲醛的加入导致线型三核络合物[Cl_2FeS_2MoS_2FeCl_2]^(2-)(低维结构)的特征电子吸收光谱消失,本文进一步讨论了在此双齿配体协助下上述无机盐体系自兜合成高维结构Mo-Fe-S簇化合物的可能性。

The more detailed study on the behavious of O-phthalaldehyde as a potent in vitro inhibitor of nitrogenase is reported, together with a study of its effect on ligan-dassisted spontaneous self-assembly procedures.
