    • Bis-platinum complexes having the formula ##STR1## wherein A is a ligand having two pairs of platinum-coordinating acidic groups which are each independently a carboxylate, phenolate, sulfonate or phosphonate group, each said pair being capable of coordinating with a platinum ion to form a 5-10 membered chelate ring; Z is a water-solubilizing group; n is 0 or a positive integer, with the proviso that n is 0 only when at least one of said platinum-coordinating acidic groups is sulfonate or phosphonate or when at least one platinum ion is a Pt(IV) ion; and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are each independently H or a C.sub.1-20 alkyl, aryl, aralkyl, or alkaryl group, or together form one or more C.sub.1-30 alkylene, cycloalkylene, arylene, aralkylene or alkarylene groups; or a pharmaceutically acceptable salt thereof, are used as readily water-soluble antitumor agents in antitumor therapy against tumors susceptible to treatment with a platinum complex.
    • 具有式的双铂络合物,其中A是具有两对铂配位酸性基团的配体,其各自独立地为羧酸酯,酚盐,磺酸酯或膦酸酯基团,每个所述对能够与铂离子配位, 形成5-10元螯合环; Z是水溶性基团; n为0或正整数,条件是仅当所述铂配位的酸性基团中的至少一个为磺酸盐或膦酸盐时或当至少一个铂离子为Pt(IV)离子时n为0; 并且R 1,R 2,R 3,R 4,R 5和R 6各自独立地为H或C 1-20烷基,芳基,芳烷基或烷芳基,或一起形成一个或多个C 1-30亚烷基,亚环烷基,亚芳基,亚芳基或亚烷基 ; 或其药学上可接受的盐作为容易水解的抗肿瘤剂用于针对易于用铂络合物治疗的肿瘤的抗肿瘤治疗。
