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), herpes simplex virus type 1 (HSV-1). These compounds are represented by formula (I) wherein: R4 is -NR¿1?R2 or oxo; R?5¿ is -CN or -CSNR¿1?R2, or -CONR1R2; R?6¿ is -H, or halo, or -NR¿1?R2; wherein R1 and R2 are independently -H or an aliphatic group; and R?7¿ is of the formula R¿3?-Ar, wherein R3 is an aliphatic group and Ar is an unsubstituted aryl or an aryl independently substituted with halo, nitro, amino, or aliphatic groups; provided that when R?5¿ is a -CN or -CSHN¿2?, and R?6¿ is a -H or -NH¿2?; and Ar is a -C6H5 or a phenyl substituted with only one aliphatic group, R3 is an aliphatic group other than methyl such that -R3 is not a -CH2; and pharmaceutically acceptable salts, prodrugs and derivatives thereof.
该发明涉及一类新型的4,5,6,7-取代的非核苷、非磷酸化的吡咯并[2,3-d]嘧啶类化合物,其表现出比已知的核苷、非核苷、非磷酸化的吡咯并[2,3-d]嘧啶衍生物更低的细胞毒性和更优越的抗病毒活性,特别是对人类DNA病毒如巨细胞病毒(HCMV)、单纯疱疹病毒1型(HSV-1)的抗病毒活性。这些化合物的化学式为(I),其中:R4为-NR1R2或氧;R5为-CN或-CSNR1R2,或CONR1R2;R6为-H,或卤素,或NR1R2;其中R1和R2独立地为-H或脂肪基;而R7为R3-Ar的结构,其中R3为脂肪基,Ar为未取代的芳基或独立取代有卤素、硝基、氨基或脂肪基的芳基;但是当R5为-CN或-CSHN2,R6为-H或NH2,且Ar为C6H5或只取代有一个脂肪基的苯基时,R3为除了甲基以外的脂肪基,-R3不为-CH2;以及其药物可接受的盐、前药和衍生物。
