摘要:
Substituted 4-phenyl-pyridones and 4-phenyl-2-alkoxypyridines are prepared by reducing corresponding 4-phenyl-pyridone and 4-phenyl-2-alkoxypyridine derivatives. The substituted 4-phenyl-pyridones and 4-phenyl-2-alkoxypyridines can be employed as active compounds in medicaments, in particular for the treatment of hyperlipoproteinaemia.
摘要:
Novel compounds for treating hyperproteinaemia, lipoproteinaemia or arteriosclerosis of the formula ##STR1## in which A, B, D and E can have varied meanings,X is --CH.sub.2 --CH.sub.2 or --CH.dbd.CH--, andR is ##STR2## wherein R.sup.21 --denotes hydrogen or alkyl andR.sup.22 --denotes hydrogen,denotes alkyl, aryl or aralkyl, ordenotes a cation,and their oxidation products.
摘要:
Substituted biphenyls can be prepared by reduction of appropriate ketones and, if appropriate, subsequent hydrolysis, cyclization, hydrogenation and separation of isomers. The substituted biphenyls can be used as active compounds in medicaments.
