Bivalent inhibitors having affinity for one or more dimeric GST isozymes are provided. The bivalent inhibitors comprise two ligand domains connected by a molecular linker, wherein the ligand domains have affinity for one or more monomers in the one or more dimeric GST isozymes. The ligand domains are separated by a distance ranging from about 5 to about 100 Å. The bivalent inhibitors of the invention demonstrate greatly improved affinity for GST isozymes. In a specific embodiment, the bivalent inhibitors of the invention further provide affinity for substantially one GST isozyme and for substantially one GST class. The bivalent inhibitors of the invention have numerous uses that include the treatment of drug-resistant cancer, malaria, and stimulation of hematopoiesis.
提供具有亲和力的双价抑制剂,用于一种或多种二聚体谷胱甘肽S-转移酶同工酶。双价抑制剂包括两个配体结构域,由分子连接物连接,其中配体结构域具有亲和力,适用于一种或多种二聚体谷胱甘肽S-转移酶同工酶中的一个或多个单体。配体结构域之间的距离范围从大约5到大约100埃。本发明的双价抑制剂表现出对GST同工酶的亲和力大大提高。在一个具体实施例中,本发明的双价抑制剂进一步提供对几乎一个GST同工酶和几乎一个GST类的亲和力。本发明的双价抑制剂具有许多用途,包括治疗耐药性癌症、疟疾和促进造血作用。
