Compounds of the formula ##STR1## wherein R is H, halo, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, 3,4-methylenedioxy, CF.sub.3, NO.sub.2, NH.sub.2, N(C.sub.1-4 alkyl).sub.2, CN, OH, --S(C.sub.1-4 alkyl) or --SO.sub.2 (C.sub.1-4 alkyl); R.sub.1 and R.sub.2 are independently each H or C.sub.1-4 alkyl or taken together with the attached N atom are morpholino, piperidino, pyrrolidino, piperazino, or N-- C.sub.1-4 -alkyl piperazino; and, when R is halo, C.sub.1-4 alkyl or C.sub.1-4 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 R.sub.1 and R.sub.2 are both not H, a quaternary ammonium salt thereof with a C.sub.1-4 alkyl halide have valuable antiviral activity, e.g., for treatment of infections caused by a herpes virus.
化合物的公式为##STR1##其中R为H,卤素,C.sub.1-4烷基,C.sub.1-4烷氧基,3,4-亚甲二氧基,CF.sub.3,NO.sub.2,NH.sub.2,N(C.sub.1-4烷基).sub.2,CN,OH,-S(C.sub.1-4烷基)或-SO.sub.2(C.sub.1-4烷基);R.sub.1和R.sub.2各自独立地为H或C.sub.1-4烷基,或者与连接的N原子一起取代为吗啡啶,哌啶,吡咯啉,哌嗪或N- C.sub.1-4-烷基哌嗪;当R为卤素,C.sub.1-4烷基或C.sub.1-4烷氧基时,x为0-3,否则为0或1;或其与酸的药物可接受盐,对于R.sub.1和R.sub.2均不为H的化合物,其与C.sub.1-4烷基卤化物的季铵盐具有有价值的抗病毒活性,例如,用于治疗由疱疹病毒引起的感染。
