Abstract

A bulky platinum triamine complex, [Pt(Me(5)dien)(NO(3))]NO(3) (Me(5)dien=N,N,N',N',N''-pentamethyldiethylenetriamine) has been prepared and reacted in D(2)O with N-acetylmethionine (N-AcMet) and guanosine 5'-monophosphate (5'-GMP); the reactions have been studied using (1)H NMR spectroscopy. Reaction with 5'-GMP leads to two rotamers of Pt(Me(5)dien)(5'-GMP-N7). Reaction with N-AcMet leads to formation of Pt(Me(5)dien)(N-AcMet-S). When a sample with equimolar mixtures of Pt(Me(5)dien)(D(2)O), 5'-GMP, and N-AcMet was prepared, Pt(Me(5)dien)(5'-GMP-N7) was the dominant product observed throughout the reaction. This selectivity is the opposite of that observed for a similar reaction of Pt(dien)(D(2)O) with 5'-GMP and N-AcMet. To our knowledge, this is the first report of a platinum(II) triamine complex that reacts substantially faster with 5'-GMP than with N-AcMet; the effect is most likely due to steric clashes between the methyl groups of the Me(5)dien ligand and the N-AcMet.

摘要

一个庞大的铂三胺配合物,[Pt(Me(5)dien)(NO(3))]NO(3)(Me(5)dien=N,N,N',N',N''-五甲基二乙撑三胺)已被制备并在 D(2)O 中与 N-乙酰甲硫氨酸(N-AcMet)和鸟苷 5'-单磷酸(5'-GMP)反应; 使用(1)H NMR 光谱研究了这些反应。与 5'-GMP 的反应导致[Pt(Me(5)dien)(5'-GMP-N7)](+)的两种旋转异构体。与 N-AcMet 的反应导致[Pt(Me(5)dien)(N-AcMet-S)](+)的形成。当制备具有[Pt(Me(5)dien)(D(2)O)](2+),5'-GMP 和 N-AcMet 的等摩尔混合物的样品时,[Pt(Me(5)dien)(5'-GMP-N7)](+)是整个反应中观察到的主要产物。这种选择性与[Pt(dien)(D(2)O)](2+)与 5'-GMP 和 N-AcMet 的类似反应观察到的选择性相反。据我们所知,这是第一个报道的铂(II)三胺配合物与 5'-GMP 的反应速度明显快于 N-AcMet 的反应速度; 这种影响很可能是由于 Me(5)dien 配体的甲基与 N-AcMet 之间的空间位阻。
