The invention concerns Au(III) complexes of the type [AuIIIX2(Pdtc)] (X = halogen, pseudo-halogen; pdtc = peptide-/esterified peptidedithiocarbamato) which are able to both maintain the antitumor properties and the lack of nephrotoxic side-effects of the previously reported Au(lll)-dithiocarbamato complexes, together with an improved bioavailability through the peptide-mediated cellular internalization. The Au(III) complexes described have shown a significant biological activity on human tumor cell lines and, thus, they can be advantageously used as antineoplastic agents. The preparation method and use for the treatment of tumor pathologies of the Au(III) complexes of the invention are further described.
本发明涉及Au(III)配合物,其
化学式为[AuIIIX2(Pdtc)] (X=卤素,伪卤素;pdtc = 肽/酯化肽二
硫代
氨基甲酸盐),这些配合物能够同时保持先前报道的Au(lll)-二
硫代
氨基甲酸盐配合物的抗肿瘤特性和缺乏肾毒性副作用,并通过肽介导的细胞内吞噬作用改善
生物利用度。所述Au(III)配合物已在人类肿瘤
细胞系上显示出显著的
生物活性,因此,它们可以作为
抗肿瘤药物有优势地使用。本发明进一步描述了所述Au(III)配合物的制备方法和用于治疗肿瘤病理的用途。
