摘要:
The present invention relates to a process for the preparation of compounds of the general Formula I ##STR1## and pharmaceutically acceptable salts thereof (wherein R stands for piperazinyl or 4-methyl-piperazinyl) which comprises reacting a compound of the general Formula II ##STR2## (wherein R.sup.1 and R.sup.2 stand for halogen; an aliphatic acyloxy group comprising 2-6 carbon atoms and optionally substituted by halogen; or an aromatic acyloxy group comprising 7-11 carbon atoms) with a piperazine of the general Formula III ##STR3## (wherein R.sup.3 represent hydrogen or methyl) or a salt thereof, hydrolysing the compound of the general Formula IV ##STR4## thus obtained (wherein R, R.sup.1 and R.sup.2 are as stated above) without or after hydrolysis and if desired converting the compound of the general Formula I thus obtained into a salt thereof or setting free the same from its salt.The compounds of the general Formula I are known antibacterial agents.The advantage of the process of the present invention is that it enables the preparation of the compounds of the general Formula I in a simple manner, with high yields and in a short reaction time.
摘要:
This invention relates to a primycin-containing colloidal basic gel comprising 5-30% of primycin and 95-70% of N-methyl-pyrrolidone-2. The invention also relates to antibacterial compositions particularly for the treatment of acne vulgaris comprising as active ingredient 0.1-100% of a primycin-containing colloidal basic gel, if desired together with further antimicrobial active ingredients, in admixture with 99.9-0% of usual inert pharmaceutical filling, diluting and other formulating additives. The invention also relates to combination composition comprising as active ingredient 1-60% of a primycin-containing colloidal basic gel and 0.1-40% of further pharmaceutical active ingredient(s), e.g. one or more antibiotic(s), chemotherapeutical agent(s), fungistatic or fungicidal agent(s), steroidal or non-steroidal antiinflammatory agent (s), epithelogenic agent(s), local anaesthetic(s), and/or vitamin(s).
摘要:
The invention relates to a new process for the preparation of compounds of the Formula I ##STR1## (wherein R stands for hydrogen or methyl) and pharmaceutically acceptable salts thereof which comprises reacting a compound of the Formula V ##STR2## (wherein R.sup.1 and R.sup.2 stand for an aliphatic acyloxy group comprising 2-6 carbon atoms and optionally substituted by halogen; or for an aromatic acyloxy group comprising 7-11 carbon atoms) with an amine of the Formula VI ##STR3## (wherein R has the same meaning as stated above) or a salt thereof and subjecting the compound of the Formula VII ##STR4## thus obtained (wherein R, R.sup.1 and R.sup.2 are as stated above) to hydrolysis after or without isolation and if desired converting the compound of the Formula I thus obtained into a salt thereof or setting free the same from its salt.The compounds of the Formula I are known antibacterial agents.The advantage of the process of the present invention is that it makes the desired compounds of the Formula I available in a simple manner, with high yields and in a short reaction time.
