摘要
靶向肿瘤细胞的药物研发近年来受到了极大的关注,除了阻断细胞信号通路的蛋白激酶抑制剂外,叶酸受体介导的药物释放也引起了研究者的广泛注意。叶酸受体在大多数人体肿瘤细胞中高度表达,而在正常细胞中很少表达或不表达。叶酸可以通过叶酸受体介导的内吞作用进入细胞,这为药物选择性释放提供了很好的途径。本文对近些年来基于叶酸受体介导的药物作用机制、设计策略,以及研发的叶酸-抗肿瘤药物缀合物进行综述,并介绍了该领域临床研究取得的最新进展。
Cancer therapies that exploit targeting ligands to deliver attached cytotoxic drugs selectively to ma- lignant cells are currently receiving significant attention. The folate receptor(FR) is a confirmed tumor-asso- ciated antigen that binds folate and folate-drug conjugates with very high affinity and shuttles these bound molecules inside cells via an endocytic mechanism. With the use of proper linkers and cleavable bond,small molecular weight, highly potent anticancer drugs can be released inside the cancer cells where they can per- form their desired cytotoxic functions. This review summarizes published activity data of various conjugates and highlights some newly emerging data from novel compounds which are currently under clinical investi- gation.
