The compositions and methods described herein disclose 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.
本文所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、双环或杂环环上。这些DHFR抑制剂对许多不同的病原微生物具有强效和选择性作用,包括来自细菌(如炭疽芽孢杆菌和甲氧西林耐药金黄色葡萄球菌)、真菌(如光滑念珠菌、白色念珠菌和新生隐球菌)和原虫(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效作用,可能有用作抗癌治疗药物。
