The invention relates to urea compounds of the formula
wherein:
R is hydrogen, loweralkyl, aralkyl;
R1 is alkyl, substituted alkyl, optionally substituted aralkyl and heteroaralkyl;
R2 is hydrogen, optionally substituted alkyl;
R3 is hydrogen, loweralkyl;
R4 is optionally substituted alkyl; or,
R3 and R4 may be connected together to form an alkylene bridge or an optionally substituted alkylene bridge containing one sulfur atom and two to three carbon atoms, or an alkylene bridge containing a double bond or a substituted alkylene bridge or an alkylene bridge bearing a benzofusion thereto; and
the pharmaceutically acceptable salts thereof, and a process for preparing the same. Those compounds are useful as antihypertensives.
本发明涉及式中的脲化合物,其中:R是氢、低级烷基、芳烷基;R1是烷基、取代的烷基、任选取代的芳烷基和杂烷基;R2是氢、任选取代的烷基;R3是氢、低级烷基;R4是任选取代的烷基;或者,R3和R4可以连接在一起形成亚烷基桥或任选取代的亚烷基桥,亚烷基桥含有一个硫原子和二至三个碳原子,或者亚烷基桥含有一个双键或取代的亚烷基桥,或者亚烷基桥含有苯并融合物;及其药学上可接受的盐,以及制备这些化合物的工艺。 这些化合物可用作抗高血压药。
