A compound selected from the group consisting of those having the formula: ##STR1## and pharmaceutically acceptable acid addition salts thereof, wherein R.sub.1 and R.sub.4 are independently selected from the group consisting of H and alkyl radicals having 1 to 4 carbon atoms; the R.sub.2 s are each of H or alkyl radicals having 1 to 4 carbon atoms or are, together, oxo; the R.sub.3 s are each H or alkyl radicals having 1 to 4 carbon atoms or are, together, oxo, provided that the R.sub.2 s or the R.sub.3 s are alkyl radicals; the 2-imidazolin-2-ylamino group may be in any of the 5-, 6, 7- or 8-positions of the quinoxaline nucleus; and R.sub.5, R.sub.6 and R.sub.7 each is located in one of the remaining 5-, 6-, 7- or 8- positions of the quinoxaline nucleus and is independently selected from the group consisting of Cl, Br, H and alkyl radicals having 1 to 3 carbon atoms. Such compounds, when administered to a mammal, provide desired thereapeutic effects, such as alternation in the rate of fluid transport in the gastrointestianl tract, reduction in intraocular pressure, and increase in renal fluid flow.
从以下化学式中选择的化合物:##STR1##和其药学上可接受的酸盐,其中R.sub.1和R.sub.4是独立选择自H和具有1至4个碳原子的烷基基团的群;R.sub.2分别为H或具有1至4个碳原子的烷基基团,或者在一起为氧代;R.sub.3分别为H或具有1至4个碳原子的烷基基团,或者在一起为氧代,前提是R.sub.2或R.sub.3为烷基基团;2-咪唑啉-2-基氨基团可以位于喹喔啉核的5-、6-、7-或8-位中的任何一个;R.sub.5、R.sub.6和R.sub.7分别位于喹喔啉核的剩余5-、6-、7-或8-位之一,并且独立选择自Cl、Br、H和具有1至3个碳原子的烷基基团的群。这些化合物在哺乳动物中使用时,提供所需的治疗效果,如改变胃肠道中的液体传输速率,降低眼压和增加肾脏液体流量。
