摘要
背景: 二氢叶酸还原酶(DHFR)是大多数原核和真核细胞生存所必需的酶,因为它参与了细胞必需成分的生物合成。DHFR作为癌症、细菌感染、疟疾、结核病、龋齿、锥虫病、利什曼病、真菌感染、流感、布鲁里溃疡和呼吸系统疾病等多种疾病的分子靶点,引起了广泛关注。不同的研究小组已经报道了不同的DHFR抑制剂来探索它们的治疗效果。尽管取得了所有这些进展,但迫切需要找到更多新的先导结构,这些结构可能用作更好和安全的DHFR抑制剂,特别是针对对已开发的候选药物耐药的微生物。 目的:本综述旨在关注该领域的最新进展,特别是过去二十年来在该领域取得的进展和发表的文章,并特别关注有前景的DHFR抑制剂。因此,本文试图重点介绍二氢叶酸还原酶的结构、DHFR抑制剂的作用机制、最近报道的DHFR抑制剂、DHFR抑制剂的各种药理学应用、已报道的硅研究数据和基于DHFR抑制剂的最新专利,以全面描绘对设计新型DHFR抑制剂感兴趣的研究人员的现状。 结论:最近的一项研究表明,大多数新的DHFR抑制剂化合物,无论是合成的还是天然衍生的,都以其结构中存在杂环部分为特征。非经典抗叶酸药物如甲氧苄啶、乙胺嘧啶和proguanil被认为是设计新型DHFR抑制剂的优秀模板,它们大多数具有取代的2,4-二氨基嘧啶基序。靶向DHFR具有巨大的潜力被研究用于治疗各种临床重要疾病的新治疗可能性。
