The invention provides compounds of the formula 1 that are active against the HSV primase enzyme:
wherein
R1 is hydroxy or amino;
R2 is hydrogen, halo, (C1-4)alkyl or (C1-4)alkoxy; R3 is hydrogen, halo, (C1-4)alkyl, (C1-4)alkoxy, amino or azido; R4 has the same significance as R2;
R5 is hydrogen or (C1-4)alkyl; and R is (C1-7)alkyl, (C3-6)cycloalkyl, {phenyl(C1-7)alkyl}, {phenyl(C1-7)alkoxy}, {{(monocyclic heterocyclo)-{(C1-7)alkoxy}}, CH(W)C(O){O-(C1-4)alkyl} wherein W is hydrogen or (C1-7)alkyl, or
wherein Y is hydrogen or (C1-7)alkyl, and Z is (C1-7)alkyl, (C3-6) cycloalkyl, {(C3-6)cycloalkyl}- {(C1-7)alkyl}, phenyl(C1-7)alkyl or {{(monocyclic heterocyclo)-{(C1-7)alkyl}}, or Y and Z together with the nitrogen atom to which they are attached represent, 1-pyrrolidinyl, 1-piperidinyl, 4-morpholinyl or 1-(4-methylpiperazinyl); with the provisos that (1) when R is CH(W)C(O)-{O-(C1-4)alkyl} as defined herein, then R5 is hydrogen; and (2) at least one of R2, R3 and R4 is other than hydrogen.
本发明提供了一种具有以下式子1的化合物,该化合物对HSV引物酶具有活性:其中R1是羟基或氨基;R2是氢、卤素、(C1-4)烷基或(C1-4)氧烷基;R3是氢、卤素、(C1-4)烷基、(C1-4)氧烷基、氨基或偶氮基;R4具有与R2相同的意义;R5是氢或(C1-4)烷基;R是(C1-7)烷基、(C3-6)环烷基、苯基(C1-7)烷基、苯基(C1-7)氧烷基、(单环杂环)-(C1-7)氧烷基、CH(W)C(O)O-(C1-4)烷基,其中W是氢或(C1-7)烷基,或者其中Y是氢或(C1-7)烷基,Z是(C1-7)烷基、(C3-6)环烷基、(C3-6)环烷基-(C1-7)烷基、苯基(C1-7)烷基或(单环杂环)-(C1-7)烷基,或者Y和Z与它们连接的氮原子一起表示1-吡咯基、1-哌啶基、4-吗啉基或1-(4-甲基哌嗪基);但是前提是(1)当R定义如本文所述为CH(W)C(O)O-(C1-4)烷基时,R5为氢;并且(2)R2、R3和R4中至少有一个不是氢。
