A salt of an anionic complex of Ru(III) with an ammonium cation fof formula (I),
where R1, R2 and R3, equal or different from each other, are selected from the group consisting of H, C1-C6 alkyl, linear or branched, saturated or unsaturated, C3-C7 cycloalkyl, phenyl and aryl; or NR1R2R3 is a 5-7-membered nitrogen-containing heterocycle, saturated or unsaturated, optionally containing one or more O, S and/or N atoms, said nitrogen atom being optionally substituted with a C1-C4 alkyl, aryl or benzyl residue; said nitrogen-containing heterocycle being optionally condensed with a benzo group and/or substituted with C1-C4 alkyl, C1-C4 alkoxyl, C1-C4 alkylthio, aryl or benzyl groups; where R4 and R5, equal or different from each other, are selected from the group consisting of H, C1-C6 alkyl, C3-C7 cycloalkyl, phenyl and aryl or R4 and R5 form, together with the S atom, a 4-7-membered heterocycle. Furthermore the process for the preparation of said salts, the pharmaceutically compositions containing the same and their use as antimetastatic and antineoplastic agents are described.
一种含铼(III)阴离子配合物和铵阳离子的盐,化学式为(I),其中R1、R2和R3相等或不同,选自H、C1-C6直链或支链饱和或不饱和烷基、C3-C7环烷基、苯基和芳基;或NR1R2R3是一种含氮的5-7元杂环,饱和或不饱和,可选地含有一个或多个O、S和/或N原子,该氮原子可用C1-C4烷基、芳基或苄基残基取代;该含氮杂环可选择与苯环基融合和/或用C1-C4烷基、C1-C4烷氧基、C1-C4烷硫基、芳基或苄基取代;其中R4和R5相等或不同,选自H、C1-C6烷基、C3-C7环烷基、苯基和芳基,或R4和R5与S原子一起形成一个4-7元杂环。此外,还描述了制备该盐的过程、含有该盐的药物组合物以及它们作为抗转移和抗肿瘤剂的用途。
