  Highly Efficient Ligands for Dihydrofolate Reductase from Cryptosporidium hominis and Toxoplasma gondii Inspired by Structural Analysis

  摘要：

  The search for effective therapeutics for cryptosporidiosis and toxoplasmosis has led to the discovery of novel inhibitors of dihydrofolate reductase (DHFR) that possess high ligand efficiency: compounds with high potency and low molecular weight. Detailed analysis of the crystal structure of dihydrofolate reductase-thymidylate synthase from Cryptosporidium hominis and a homology model of DHFR from Toxoplasma gondii inspired the synthesis of a new series of compounds with a propargyl-based linker between a substituted 2,4-diaminopyrimidine and a trimethoxyphenyl ring. An enantiomerically pure compound in this series exhibits IC50 values of 38 and 1 nM against C. hominis and T. gondii DHFR, respectively. Improvements of 368-fold or 5714-fold (C. hominis and T. gondii) relative to trimethoprim were generated by synthesizing just 14 new analogues and by adding only a total of 52 Da to the mass of the parent compound, creating an efficient ligand as an excellent candidate for further study.

  The compositions and methods described herein discloses the design, synthesis and testing of compounds that act as inhibitors of DHFR. The basic scaffold of these inhibitors includes a 2,4-diaminopyrimidine ring with a propargyl linker to another substituted aryl, bicyclo or heteroaryl ring. These DHFR inhibitors are potent and selective for many different pathogenic organisms, including the DHFR enzyme from bacteria such as Bacillus anthracis and methicillin-resistant Staphylococcus aureus , fungi such as Candida glabrata, Candida albicans and Cryptococcus neoformans and protozoa such as Cryptosporidium hominis and Toxoplasma gondii . These compounds and other similar compounds are also potent against the mammalian enzyme and may be useful as anti-cancer therapeutics.

  本文描述的组合物和方法揭示了设计、合成和测试作为DHFR抑制剂的化合物。这些抑制剂的基本骨架包括一个2,4-二氨基嘧啶环，带有一个丙炔基连接到另一个取代芳基、双环或杂环芳基环。这些DHFR抑制剂对许多不同的病原体具有强大的选择性作用，包括来自细菌如炭疽芽胞杆菌和耐甲氧西林金黄色葡萄球菌、真菌如白色假丝酵母、白念珠菌和新生隐球菌，以及原虫如人类隐孢子虫和弓形虫的DHFR酶。这些化合物和其他类似化合物也对哺乳动物酶具有强大的作用，可能有助于作为抗癌治疗药物。

  Striking gold: A series of variously functionalized propynyl arenes was smoothly converted into indan‐2‐ones by a new gold(I)‐catalyzed oxidative cyclization process. [LAu]NTf2 (Tf=trifluoromethanesulfonyl) is a superior catalyst both in terms of yield and kinetics for the present transformation.
