    • One aspect of the present invention relates to a process of making cyclohexane-1,2-di(O)-4,5-di(N) diastereomers which are useful as a synthons for various diastereoisomeric pharmaceutical systems. The present invention also relates to the stereoisomer compounds which are derived from retro- synthetic analysis. In another aspect, the present invention relates to novel antineoplasic Pt(II) complexes derived from the stereoisomers and the processes for making such Pt(II) complexes. Mono- and di-hydroxyl substitution on the cyclohexane ring renders the organoplatinum complex relatively more water soluble, thereby facilitating intravenous administration. The Pt(II) complexes of the present invention are less nephrotoxic than cisplatin and are readily excreted via the kidney due to their enhanced water solubility. In a composition aspect, the present invention encompasses novel pharmaceutical compositions comprising the novel Pt(II) complexes in an amount sufficient to have an antineoplastic effect in an animal or patient.
    • 本发明的一个方面涉及可用作各种非对映体药物体系的合成子的环己烷-1,2-二(O)-4,5-二(N)非对映异构体的方法。 本发明还涉及衍生自逆合成分析的立体异构体化合物。 另一方面,本发明涉及衍生自立体异构体的新型抗磷酸化Pt(II)配合物和制备这种Pt(II)络合物的方法。 环己烷环上的单羟基和二羟基取代使得有机铂复合物相对更易溶于水,从而便于静脉内给药。 本发明的Pt(II)配合物与顺铂相比肾毒性较低,由于其水溶性增强,容易通过肾脏排出。 在组合物方面,本发明包括新颖的药物组合物,其包含新颖的Pt(II)配合物,其量足以在动物或患者中具有抗肿瘤作用。
