摘要:
5-Aroyl-4-RO-, 5-aroyl-4-RS-, 5-aroyl-4-RSO-, 5-aroyl-4-RSO.sub.2 -, or 5-pyrrylcarbonyl-pyrrole alkanoic acid have been prepared via hydrolysis of a precursor-ester after high temperature decarboxylation or from direct acidic decarboxylation of a precursor diacid. The compounds are analgesic and anti-inflammatory agents of high activities but low ulcerogenic side effects.

New substituted azetidinones of the general Formula (I) which have been found to be potent elastase inhibitors and thereby useful anti-inflammatory and antidegenerative agents are described. ##STR1## wherein R.sub.4 is (a) ##STR2## or (b) ##STR3## where R.sub.x is carboxy C.sub.1-6 alkyl, benzyloxycarbonylC.sub.1-3 alkyl, or t-butoxycarbonylC.sub.1-3 alkyl,whereinQ is a covalent bond or ##STR4## wherein R.sub.5 and R.sub.6 are each individually C.sub.1-3 alkyl or hydrogen,Y is ##STR5## or a covalent bond.
摘要:
Tricyclic derivatives of substituted pyrrole acids, e.g., substituted 4,10-dihydro-10-oxo-1H-[1]benzoxepino[4,3-b]pyrrole-2-acetic acids or the 5-thia analogs thereof have been prepared via hydrolysis of a precursor or decarboxylation of a precursor-diacid. These tricyclic compounds are found to have high analgesic and anti-inflammatory activities but low ulcerogenic side effects.
