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(I)表示的
喹唑啉衍
生物;其中:R2为氢、NR′R″、C1-7烷基、芳基C1-7烷基或C3-10环烷基;R4为
氨基、C1-7烷基、C2-7烯基、C3-10环烷基、C3-10环烯基、芳基、杂环、芳基烷基、杂环取代的C1-7烷基或C3-10环烷基-C1-7烷基;R5为氢或C1-7烷基,或R5与R4一起与它们所连接的氮原子形成杂环环;Y为单键、C1-7亚烷基、C2-7烯基或C2-7炔基;R6为卤素、杂环芳基或芳基;R′和R″各自独立地为氢、C1-7烷基-羰基或C1-7烷基;前提是当R2为H且R5为H时,R4不是取代了
吗啡啉的苯基,且当NR4R5为
哌嗪基时,所述的NR4R5要么是非取代的,要么是取代了甲基或乙酰基的;其中所述的衍
