NOUVEAUX DERIVES DE L'ERYTROMYCINE, LEUR PROCEDE DE PREPARATION ET LEUR APPLICATION COMME MEDICAMENTS

摘要

The invention concerns compounds of formula (I) in which A and B form with the atoms to which they are bound a group (a): R1 = NH2, NH-alkyl, NH-alkenyl, NH-alkynyl, (CH2)nAr, NH(CH2)nAr or N=NH(CH2)nAr, Ar = aryl or heteroaryl, optionally substituted; R = H, alkyl optionally substituted, optionally interrupted by one or several heteroatoms, aryl or heteroaryl, optionally substituted, as well as the salts of compounds of formula (I). The compounds of formula (I) have interesting antibiotic properties.
