NEW SUBSTITUTED AZETHIDINONES, METHOD OF THEIR SYNTHESIS, PHARMACEUTICAL COMPOSITION, TREATMENT METHOD

摘要

FIELD: organic chemistry. SUBSTANCE: product: substituted azethidinones of the general formula (I) where: Rmeans (a) or (b) where Rmeans carboxy-C-alkyl, benzylhydroxycarbonyl-C-alkyl or t-butoxycarbonyl-C-alkyl where Q means covalent bond or (C). Y means (d) or (e) or covalent bond. The synthesized compounds are powerful inhibitors of elastase and can be used as antiinflammatory and antidegenerative agents. EFFECT: improved method of synthesis, enhanced effectiveness.
