Compound represented by the following Formula IV:
wherein
R₁ is hydrogen, or a C₁-C₆ alkyl or C₁-C₆ alkoxy group;
R₂ is an isopropylamino, tert-butylamino,
2-(2-methoxyphenyl)ethyl-1-amino,
4-(2-methoxyphenyl)]-1-piperazinyl or
4-piperonyl-1-piperazinyl group
and pharmacologically acceptable salts thereof are hypotensive agents and, except when R₁ is hydrogen when R₂ is isopropylamino or tert-butylamino group, are antiglaucoma agents. Except for compounds in which (i) R₁ is hydrogen and R₂ is isopropylamino or tert-butylamino or (ii) R₁ is methyl and R₂ is isopropylamino, the compounds of Formula IV are novel.

其中
R₁ 是氢、C₁-C₆ 烷基或 C₁-C₆ 烷氧基;
R₂ 是异丙基氨基、叔丁基氨基、
2-(2-甲氧基苯基)乙基-1-氨基
4-(2-甲氧基苯基)]-1-哌嗪基或
4-哌壬基-1-哌嗪基团
及其药理上可接受的盐类是降血压药,并且,除了当 R₁ 为氢时,当 R₂ 为异丙基氨基或叔丁基氨基时,是抗青光眼药。除了 (i) R₁ 为氢且 R₂ 为异丙基氨基或叔丁基氨基或 (ii) R₁ 为甲基且 R₂ 为异丙基氨基的化合物外,式 IV 的化合物均为新型化合物。
