The present invention provides a compound of formula (I), wherein R1 is selected from hydrogen, hydroxyl, fluoro or a C1-4alkoxy group or R1 is linked to R3 to form a 4, 5 or 6-membered aliphatic ring optionally containing one N or O atom; R2 is selected from cyclopentyl or cyclohexyl optionally substituted by a fluoro; R3 is hydrogen or is linked to R1 as hereinbeforedefined; R4 is hydrogen, a C1-4alkyl group optionally substituted by a group NR8R9 in which R8 and R9 are each hydrogen or a C1-4alkyl group or R4 is linked to R6 to form a (CH2)mNR10SO2N group wherein m is an integer selected from 2 or 3 and R10 is a C1-4 alkyl group; R5 is hydrogen or a C1-4 alkyl group; R6 is hydroxyl or is linked to R4 as hereinbefore defined; R7 is hydrogen or an aliphatic ring of 4-7 ring atoms containing one or two heteroatoms selected from O, N or S or a group S(O), S(O)2,NH or NC1-4alkyl and optionally substituted by fluoro or R7 is a 5- 10-membered heteroaromatic ring system containing 1 to 4 heteroatoms independently selected from N, O and S, which ring is optionally substituted by one or two halo atoms or C1-4alkyl or C1-4alkoxy groups; Y is a single bond or a CH2 group; when R4 is linked to R6 and m is 3 then Y is a single bond; when R4 is linked to R6 and m is 2 then Y is a CH2 group; n is an integer from zero to four, with the proviso that when R1 is hydrogen, n is not zero; or a pharmaceutically acceptable salt thereof, pharmaceutical formulations containing it and its use in medicine, particularly for the treatment of HCV infections. Hepatitis C (HCV) is a cause of viral infections. Methods of preparing compounds of the formula (I) arc also disclosed.
本发明提供了一种化合物,其化学式为(I),其中R1选自氢、羟基、氟或C1-4烷氧基,或者R1与R3连接形成一个含有一个N或O原子的4、5或6元脂环;R2选自环戊基或环己基,可以选择地被氟取代;R3为氢或与上述定义的R1连接;R4为氢,一个C1-4烷基,可以选择地被NR8R9基团取代,其中R8和R9分别为氢或C1-4烷基,或者R4与R6连接形成(CH2)mNR10SO2N基团,其中m为2或3的整数,R10为C1-4烷基;R5为氢或C1-4烷基;R6为羟基或与上述定义的R4连接;R7为氢或含有一个或两个来自O、N或S的杂原子的4-7环原子的脂环,或者为S(O)、S(O)2、NH或NC1-4烷基基团,可以选择地被氟取代,或者R7为含有1至4个来自N、O和S的杂原子的5-10元杂芳环系统,该环可以选择地被一个或两个卤原子或C1-4烷基或C1-4烷氧基取代;Y为单键或CH2基团;当R4与R6连接且m为3时,Y为单键;当R4与R6连接且m为2时,Y为CH2基团;n为0到4的整数,但当R1为氢时,n不为零;或其药学上可接受的盐,包含它的药物制剂以及其在医学上的应用,特别是用于治疗丙型肝炎(HCV)感染。丙型肝炎(HCV)是病毒感染的原因。还公开了制备化合物(I)的方法。
