Pyrrolo[2,3-d] pyrimidines as antiviral agents
-
Scheme 3, (2010/11/29)
This invention relates to a novel class of 4,5,6,7-substituted non-nucleoside, non-phosphorylatable pyrrolo[2,3-d]pyrimidines which exhibit both significantly lower levels of cytotoxicity and superior antiviral activity than known nucleoside, non-nucleoside, and non-nucleoside, non-phosphorylatable pyrrolo[2,3-d]pyrimidine derivatives, particularly against human DNA viruses such as cytomegalovirus (HCMV) and herpes simplex virus type 1 (HSV-1). These compounds are represented by the following formula: wherein: R4is —NR1R2or oxo; R5is —CN, or —CSNR1R2, or —CONR1R2; R6is —H, or halo, or —NR1R2; wherein R1and R2are independently —H or an aliphatic group; and R7is of the formula R3—Ar, wherein R3is an aliphatic group and Ar is an unsubstituted aryl or an aryl independently substituted with halo, nitro, amino, or aliphatic groups; provided that when R5is a —CN or —CSNH2, and R6is a —H or —NH2, and Ar is a —C6H5or a phenyl substituted with only one aliphatic group, R3is an aliphatic group other than methyl such that —R3— is not a —CH2—; and pharmaceutically acceptable salts, prodrugs and derivatives thereof.
