Compounds comprising two human GlxI inhibitors covalently linked via a chemical linker are provided, wherein each of said two human GlxI inhibitors, which may be the same or different, is an S-substituted glutathione or an S-substituted glutathione prodrug, wherein said GlxI inhibitors each have a γ-glutamyl amino group, wherein said chemical linker is covalently bound to each GlxI inhibitor via said γ-glutamyl amino group, and wherein said chemical linker has a length of at least 50 Angstroms. Monovalent irreversible inactivators of human GlxI are also provided. An antineoplastic composition is provided, which comprises a compound described above and a pharmaceutically acceptable carrier. In vitro and in vivo methods of preventing or inhibiting the growth and proliferation of neoplastic cells and/or tumors are also provided.
本发明提供了由化学连接剂共价连接的两种人类GlxI抑制剂组成的化合物,其中每种人类GlxI抑制剂(可以相同或不同)是S-取代谷胱甘肽或S-取代谷胱甘肽前药,其中每个GlxI抑制剂具有γ-谷氨酰氨基,其中所述化学连接剂通过所述γ-谷氨酰氨基与每个GlxI抑制剂共价结合,且所述化学连接剂的长度至少为50埃。本发明还提供了人类GlxI的单价不可逆失活剂。本发明还提供了一种抗肿瘤组合物,其包括上述化合物和药学上可接受的载体。本发明还提供了预防或抑制肿瘤细胞和/或肿瘤生长和增殖的体外和体内方法。
