This invention relates to novel compounds for preventing or retarding the degradation of elastin or other proteins and therefore preventing or retarding the disease states caused by said degradation, of the formula: ##STR1## or its pharmacologically acceptable salts. The invention also relates to novel methods and intermediates for making the compounds. The intermediate compound being of the formula: ##STR2## wherein R.sub.2 is (a) halogen; or (b) trifluoromethyl; wherein R.sub.3 is (a) --C(O)R.sub.4 ; (b) --CH(OH)R.sub.4 ; (c) --CH.sub.2 R 4; or (d) --CH.dbd.CHR.sub.4 ; wherein R.sub.4 is alkyl or 13 to 25 carbon atoms inclusive, and the pharmacologically acceptable base addition salts thereof.
本发明涉及一种新型化合物,用于预防或延缓弹性蛋白或其他蛋白质的降解,从而预防或延缓由此降解引起的疾病状态,其化学式为:##STR1##或其药理学上可接受的盐。本发明还涉及制备该化合物的新方法和中间体。中间体化合物的化学式为:##STR2##其中R.sub.2为(a)卤素;或(b)三氟甲基;其中R.sub.3为(a)--C(O)R.sub.4;(b)--CH(OH)R.sub.4;(c)--CH.sub.2R.sub.4;或(d)--CH.dbd.CHR.sub.4;其中R.sub.4为烷基或含13至25个碳原子的烷基,以及其药理学上可接受的酸加盐。
