This invention provides quinazoline derivatives represented by the structural formula: (I); wherein: R2 is hydrogen, NR′R″, C1-7 alkyl, arylC1-7 alkyl or C3-10 cycloalkyl; R4 is amino, C1-7 alkyl, C2-7 alkenyl, C3-10 cycloalkyl, C3-10 cycloalkenyl, aryl, heterocyclic, arylalkyl, heterocyclic-substituted C1-7 alkyl or C3-10 cycloalkyl-C1-7 alkyl; R5 is hydrogen or C1-7 alkyl, or R5 and R4 together with the nitrogen atom to which they are attached form a heterocyclic ring; Y is a single bond, C1-7 alkylene, C2-7 alkenylene or C2-7 alkynylene; R6 is halogen, heteroaryl or aryl; R′ and R″ are each independently hydrogen, C1-7 alkyl-carbonyl or C1-7 alkyl; provided that R4 is not phenyl substituted with morpholino when R2 is H and R5 is H, and provided that when NR4R5 is piperazinyl, said NR4R5 is either non-substituted or substituted with methyl or acetyl; a pharmaceutically acceptable addition salt, a stereoisomer, a mono- or a di-N-oxide, a solvate or a pro-drug thereof, for the treatment of viral infections.
本发明提供了由结构式表示的喹唑啉衍生物:(I);其中R2是氢、NR′R″、C1-7烷基、芳基C1-7烷基或C3-10环烷基;R4是氨基、C1-7烷基、C2-7烯基、C3-10环烷基、C3-10环烯基、芳基、杂环基、芳烷基、杂环基取代的C1-7烷基或C3-10环烷基-C1-7烷基;R5 是氢或 C1-7 烷基,或 R5 和 R4 与它们所连接的氮原子一起形成杂环;Y 是单键、C1-7 亚烷基、C2-7 亚烯基或 C2-7 亚炔基;R6是卤素、杂芳基或芳基;R′和R″各自独立地是氢、C1-7烷基-羰基或C1-7烷基;条件是当R2是H和R5是H时,R4不是被吗啉基取代的苯基,并且当NR4R5是哌嗪基时,所述NR4R5是非取代的或被甲基或乙酰基取代的;用于治疗病毒感染的药学上可接受的加成盐、立体异构体、单-或二-N-氧化物、溶 剂或原药。
