摘要:
Aminoketone derivative compounds containing a heterocyclic ring bonded to an aminoketone moiety and useful as effective ingredients of centrally acting muscle relaxants and pollakiurea curing agents.(+)3-phenyl-5-[2-(1-pyrrolidinylmethyl)butyryl]isoxazole, which has a more remarkable central muscle relaxant action as compared with its racemic modification, can be effectively separated from the racemic modification using optically active 10-camphorsulfonic acid as the agent for the optical resolution.
摘要:
The isoquinoline derivatives represented by the following general formula (I) are useful as cardiotonics having high cardiotonic activity and low toxicity: ##STR1## where R.sub.1 represents a lower C.sub.1 -C.sub.4 alkyl group or cyclopropyl group,R.sub.2 represents formyl group, lower C.sub.1 -C.sub.4 alkanoyl group and benzoyl group, lower C.sub.1 -C.sub.4 alkyl group, lower C.sub.1 -C.sub.4 alkenyl group, lower C.sub.1 -C.sub.4 hydroxy substituted alkyl group, C.sub.1 -C.sub.4 perfluoroalkyl group andR.sub.3 represents 4-pyridyl group or 2-pyridyl group respectively,and the therapeutically acceptable salts thereof are also useful as cardiotonics.

摘要:
Disclosed are 2-thiazol derivatives having the general formula ##STR1## where R.sub.1 and R.sub.2 independently represent lower alkyl radicals having 1 to 4 carbon atoms and X represents a lower alkyl radical, a lower alkoxy radical, a lower alkoxycarbonyl radical, a halogenoalkoxy radical, a radical of the formula ##STR2## or a radical of the formula ##STR3## Also disclosed are a process for preparing the derivatives and pharmaceutical compositions having immunomodulatory activity which comprise the derivatives as the active ingredient.
摘要:
The present invention provides new thiazole compounds possessing immuno-modulating activity, i.e. thiazole compounds of the general formula (1): ##STR1## wherein R.sub.1 stands for a hydrogen or halogen atom or a lower alkyl, lower alkoxy, substituted or unsubstituted phenoxy, nitro or cyano group, R.sub.2 for a hydrogen atom or a lower alkyl or lower alkylthio group, and R for an .alpha.-halogenoalkyl group or the grouping: ##STR2## a process for preparing same and pharmaceutical compositions containing the thiazole compounds.More particularly, the present invention provides new thiazole compounds of the above general formula (1) which have immuno-modulating activity and are thus effective against immunodiseases such as chronic rheumatoid arthritis and also useful against viral diseases or for the immunotherapy of cancers, but show weak toxicity and are thus extremely desirous as medicines, a process for the preparation of the thiazole compounds and pharmaceutical compositions containing the thiazole compounds.
