摘要:
The invention relates to the inclusion complexes of 7-isopropoxy-isoflavon formed with cyclodextrin or cyclodextrin derivatives as well as to the pharmaceutical compositions containing these inclusion complexes as active ingredient. The invention further relates to the preparation of the new inclusion complexes.The new inclusion complex according to the invention shows higher dissolution and resorption properties as compared to the active ingredient administered per se.
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:
Antitussive compounds of the formula I ##STR1## or physiologically acceptable acid addition salts thereof are disclosed, where A stands for straight or branched chain C.sub.1-5 alkylene or ##STR2## R.sub.1 stands for straight or branched chain C.sub.1-10 alkyl, halogenoalkyl, hydroxyalkyl, C.sub.5-6 cycloalkyl, vinyl, 2-ethoxyethyl, carbonylalkyl or aminoalkyl of the formula ##STR3## wherein R stands for hydrogen or methyl, n is 0 to 3,R.sub.2 stands for hydrogen or straight or branched chain alkyl,R.sub.3 stands for hydrogen or straight or branched chain alkyl or,R.sub.2 and R.sub.3 together with the nitrogen atom may form a 5-6 membered ring, which ring can optionally contain an oxygen or a second nitrogen atom, the latter, optionally substituted by methyl or,R.sub.1 can stand for a phenyl group of the formulaR.sub.4 R.sub.5 C.sub.6 H.sub.3 whereinR.sub.4 and R.sub.5 represent independently hydrogen, chlorine, hydroxy, methoxy, ethoxy, methyl or amino or,R.sub.1 may further stand for hydroxy, in this case the compound of the formula I may exist according to the conditions in the form of tautomers of the formula Ia ##STR4## and R.sub.1 may further stand for benzyl, 2,2-diphenylethyl or theophyllin-7-yl-methyl.
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.
