The compounds of this invention are designated as quinoxalinyl esters of carbamimidothioic acids and exhibit the pharmacological properties of preventing gastric ulcers, reducing gastric secretions and lowering blood pressure. The compounds have the following structural formula: ##STR1## in which Q is hydrogen or nitro; A is hydrogen, methyl, ethyl, propyl, isopropyl, n-butyl, carbomethoxy, carbethoxy, carbopropoxy, carbisopropoxy, carbobutoxy, carbisobutoxy, or carbo-t-butoxy; and R.sup.1, R.sup.2, and R.sup.3 are, independently, hydrogen, methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, t-butyl, allyl, or R.sup.1 and R.sup.3 may be concatenated with a carbon chain having 4 carbon atoms with R.sup.2 then being hydrogen; except that, when A and Q are hydrogen, R.sup.1, R.sup.2, and R.sup.3 may not all be hydrogen; and with the further exception that, where A is methyl and R.sup.1, R.sup.2, and Q are all hydrogen, R.sup.3 may not be ethyl; or a pharmaceutically acceptable salt thereof.
本发明的化合物被命名为喹诺克林基羧酸酰胺基硫酸酯,并具有预防胃溃疡、减少胃分泌和降低血压的药理性质。这些化合物的结构公式如下:##STR1## 其中Q是氢或硝基;A是氢、甲基、乙基、丙基、异丙基、正丁基、甲氧基羰基、乙氧基羰基、丙氧基羰基、异丙氧基羰基、丁氧基羰基、异丁氧基羰基或叔丁氧基羰基;R1、R2和R3独立地为氢、甲基、乙基、丙基、异丙基、正丁基、异丁基、叔丁基、烯丙基,或者R1和R3可以与一个有4个碳原子的碳链连接,此时R2为氢;除了当A和Q都是氢时,R1、R2和R3不能都是氢;以及进一步的例外是,当A是甲基且R1、R2和Q都是氢时,R3不能是乙基;或其药用可接受的盐。
