This invention relates to compounds of the formula ##STR1## wherein R.sub.1 represents a linear or branched alkyl of from 1 to 20 carbon atoms; R.sub.2 represents a hydrogen or halogen atom, a linear or branched alkyl or alkoxy of from 1 to 4 carbon atoms, or a divalent group --CH.dbd.CH--CH.dbd.CH-- or --(CH.sub.2).sub.n --, in which n is an integer of from 3 to 5, with the free valences bonded in the o-position relative to one another; and R.sub.3 represents a linear or branched alkyl of from 3 to 10 carbon atoms, with the provisos that R.sub.3 is not tert.butyl when R.sub.1 is ethyl or propyl and R.sub.2 is a hydrogen atom and that R.sub.3 is not isopropyl when R.sub.1 is propyl and R.sub.2 is a hydrogen atom, or a non-toxic, pharmacologically acceptable acid addition salt thereof. The compounds of Formula I are useful for treatment and prophylaxis of diseases of the coronaries, for the treatment of hypertension, and for treatment of cardiac arrhythmia, particularly tachycardia.
本发明涉及以下结构的化合物##STR1##其中R.sub.1代表1至20个碳原子的直链或支链烷基;R.sub.2代表氢原子或卤素原子,1至4个碳原子的直链或支链烷基或烷氧基,或者--CH.dbd.CH--CH.dbd.CH--或--(CH.sub.2).sub.n --这样的二价基团,其中n是从3到5的整数,自由价键位于相对的o-位置;R.sub.3代表3至10个碳原子的直链或支链烷基,但要注意的是当R.sub.1是乙基或丙基且R.sub.2是氢原子时,R.sub.3不是叔丁基;当R.sub.1是丙基且R.sub.2是氢原子时,R.sub.3不是异丙基;或其非毒性、药理学可接受的酸盐。公式I的化合物可用于冠状动脉疾病的治疗和预防,用于高血压的治疗,以及用于治疗心律失常,特别是心动过速。
