专利号:US-8853228-B2 优先权日:2007-06-04 标 题:Heterocyclic analogs of propargyl-linked inhibitors of dihydrofolate reductase 发明人:ANDERSON AMY C; WRIGHT DENNIS L; FREY KATHLEEN MARY; PAULSEN JANET LEIGH; SCOCCHERA ERIC WILLIAM; VISWANATHAN KISHORE 权利人:ANDERSON AMY C; WRIGHT DENNIS L; FREY KATHLEEN MARY; PAULSEN JANET LEIGH; SCOCCHERA ERIC WILLIAM; VISWANATHAN KISHORE; UNIV CONNECTICUT 摘要: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.
