Abstract

The metal complexes Pd(MP)2.2H2O, Pt(MP)2H2O (MPH=6-mercaptopurine), Pt(AMP2.3H2O and Pd3(AMP)4Cl2(AMPH).4H2O (AMPH=thioguanine) have been isolated. They were screened for anti-tumour activity in the L-1210 lymphoid leukaemia test system in mice. All 4 show marked anti-tumour activity, the complex Pt(AMP)2.3H2O giving a T/C of 185 at the optimum dosage. However, the anti-tumour activity of the metal complexes is somewhat less than that shown by the parent purines under the same conditions.

摘要

已分离出金属配合物Pd(MP)₂·2H₂O、Pt(MP)₂H₂O（MPH = 6 - 巯基嘌呤）、Pt(AMP)₂·3H₂O和Pd₃(AMP)₄Cl₂(AMPH)·4H₂O（AMPH = 硫鸟嘌呤）。在小鼠L - 1210淋巴细胞白血病测试系统中对它们进行了抗肿瘤活性筛选。所有这4种配合物都显示出显著的抗肿瘤活性，配合物Pt(AMP)₂·3H₂O在最佳剂量下的T/C为185。然而，在相同条件下，金属配合物的抗肿瘤活性略低于母体嘌呤所显示的活性。
