顺铂与F-肌动蛋白的结合方式的LMCT谱研究

本文根据顺铂及顺铂与F-肌动蛋白电子光谱中电荷转移谱带研究了顺二氨合铂(II)离子与F-肌动蛋白的结合方式及构型.将所得光谱解极为个别吸收谱带,并与按不同构型、不同配位原子计算结果相比较,结果表明,铂以平面四方形构型主要与两个氨分子、一个硫和一个氨基氮配位.

Study on the binding mode of cis-platin to F-actin on the basis of LMCT spectra

The binding mode and configuration of cisplatin with F-actin were studied on the basis of charge transfer bands in the electronic spectra of cisplatin and cisplatin-F0-actin. The spectra were resolved to individual absorption bands and were compared with the calculated values corresponding to different binding configurations and ligating atoms. The results indicate a square planar configuration with two ammonia nitrogen, one sulfur and one amino nitrogen binding to platinum.
