Described are 1-phenyl-5-amino-1-penten- 3-on- derivatives of the general formula
wherein R is H, halo, Ci-4 alkyl, C1-4 alkoxy, 3,4-methylenedioxy, CF3, N02, NH2, N(C1-4 alkyl)2, CN, OH, -S(Ci-4 alkyl) or -SO2(C1-4 alkyl); R1 and R2 are independently each H or C1-4 alkyl or taken together with the attached N atom are morpholino, piperidino, pyrrolidino, piperazino, or NC1-4-alkyl piperazino; and, when R is halo, C1-4 alkyl or C14 alkoxy, x is 0-3 and, otherwise, is 0 or 1; or a pharmaceutically acceptable salt thereof with an acid or for the compounds wherein R1 and R2 are both not H, a quaternary ammonium salt thereof with a C1-4 alkyl halide and a process for their production. The compounds have valuable antiviral activity, e.g. for treatment of infections caused by a herpes virus.
所述的是通式为 1-苯基-5-氨基-1-戊烯-3-基衍生物
其中 R 是 H、卤素、Ci-4 烷基、C1-4 烷氧基、3,4-亚甲二氧基、CF3、N02、NH2、N(C1-4 烷基)2、CN、OH、-S(Ci-4 烷基)或-SO2(C1-4 烷基);R1 和 R2 独立地各自是 H 或 C1-4 烷基,或与所附 N 原子一起是吗啉基、哌啶基、吡咯烷基、哌嗪基或 NC1-4 烷基哌嗪基;当 R 为卤素、C1-4 烷基或 C14 烷氧基时,x 为 0-3,否则为 0 或 1;或其与酸的药学上可接受的盐,或对于 R1 和 R2 均非 H 的化合物,其与 C1-4 烷基卤化物的季铵盐及其生产工艺。这些化合物具有宝贵的抗病毒活性,例如可用于治疗由疱疹病毒引起的感染。
