  铂配合物与一个单齿配体（1-甲基苯并咪唑或抗病毒利巴韦林）两侧是 Twocis-NMe2 基团：用于评估配体间相互作用的信息模型

  摘要：

  具有三齿胺配体 (A3) 和核碱基 (L) 的铂配合物代表了非常有用的模型，可用于研究核碱基/顺式胺相互作用，而不会出现更常用的顺式 A2PtL2 模型系统 (A2) 中存在的核碱基/核碱基干扰引起的并发症= 两个单齿胺或一个二胺）。在这种情况下，先前研究过的 Me3dienPtL 复合物（Me3dien = N1,N4,N7-三甲基二亚乙基三胺）特别有用。每个末端氮原子上的甲基基团的存在使得 L 在 NMR 时间尺度上围绕 Pt-L 键的旋转变慢，并且由配位平面定义的两个半空间不等价。因此，通过旋转鸟嘌呤的 O6 原子和顺式胺的 NH 基团之间的 H 键相互作用，发现鸟嘌呤和脱氧鸟嘌呤衍生物具有相当的旋转速率。我们现在已将研究扩展到 Me5dien 复合物（Me5dien = N1,N1',N4,N7,N7'-五甲基二亚乙基三胺）。结果表明，末端氮原子上没有质子不仅使 L 的旋转速率降低了

  The synthesis and the stereochemical characterisation of platinum complexes containing one molecule of antiviral drug, penciclovir or famciclovir (L), and different sets of ancillary ligands (Cl,(NH3)(3-x), X=1 or 2, and N,N,N',N",N"-pentamethyldiethylenetriamine, pmdien) are reported. Penciclovir is a guanosine analogue, while famciclovir is a prodrug of penciclovir lacking the oxygen in position 6 of the purine ring. The investigation has allowed comparison of structural features of platinum derivatives with different bulk of the carrier ligand(s) and of the purines. NMR experiments (particularly diagnostic are the H8 and H6 chemical shifts of the purine) indicate that in compounds with non-bulky carrier ligands (Cl-x(NH3)(3-x)) the purine is free to rotate about the Pt-N7 bond. In contrast, in complexes with bulky carrier ligand (pmdien) there is restricted rotation about the Pt-N7 bond and the purine is constrained in a "quasi orthogonal" position with respect to the platinum coordination plane. Because of the slow rotation for [Pt(pmdien)(L)](2), two rotamers are observed in solution differing for the relative positions of the six-membered ring of the purine and the central N-methyl of pmdien with respect to the platinum coordination plane (on the same side or on opposite sides for endo and exo rotamers, respectively). Penciclovir, having an oxygen atom in position 6 of the purine ring, favours the exo over the endo rotamer while famciclovir, having just a hydrogen atom in position 6, favours the endo over the exo rotamer. The change in rotamer preference suggests that intramolecular interactions involving mostly the substituent in position 6 of the purine and the terminal N-methyls of pmdien have opposite character for the two antiviral ligands. Biological tests have confirmed that cationic platinum species of formula cis-[PtCl(NH3)(2)(L)](+) can have cytotoxicity towards tumour cells greater than corresponding compounds of formula cis-[PtCl2(NH3)(L)].
