The invention relates to compounds of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.2 ' X, Y, Z, A, B, Q and n are as described herein. Their pharmaceutically acceptable salts, and when appropriate, enantiomers, racemates, diastereomers or mixtures thereof or geometric isomer or mixtures thereof, and pharmaceutically acceptable salts thereof. The compounds of formula I inhibit enzyme carnitine acyltransferase 1 (CAT-1) and are therefore useful in the prevention of injury to ischemic tissue, and can limit infarct size, improve cardiac function and prevent arrhythmias during and following a myocardial infarction.
本发明涉及公式 ##STR1## 中的化合物,其中R.sub.1、R.sub.2、R.sub.2'、X、Y、Z、A、B、Q和n如本文所述。其药学上可接受的盐,以及在适当情况下的对映体、外消旋体、非同分异构体或其混合物或几何异构体或其混合物,以及其药学上可接受的盐。公式I的化合物抑制酶肉碱酰转移酶1(CAT-1),因此在预防缺血组织损伤方面有用,并且可以限制梗死面积,改善心功能并在心肌梗死期间和之后预防心律失常。
