摘要:
Organic amide compounds of the formula ##STR1## wherein R.sub.1 --CO is a residue of a carboxylic acid with the proviso that the carboxylic acid is not a natural fatty acid normally bound to nitrogen of nitrogenous lipids, R.sub.2 is a hydrogen atom, a C.sub.1-7 alkyl group, or a C.sub.4-7 cycloalkyl group, and R.sub.3-N is a residue of a nitrogenous lipid. The compounds are useful in increasing or stimulating the in vivo biological activity of in vitro biologically active carboxylic acids.
摘要:
A compound having the formula: ##STR1## wherein R.sub.1 is halogen or a substituted or unsubstituted hydrocarbon group; R.sub.2 R.sub.6 and R.sub.7, which may be the same or different, each represents hydrogen or a substituted or unsubstituted hydrocarbon group, or R.sub.6 and R.sub.7 taken together may represent a hetero group having one or more hetero atoms; R.sub.3 and R.sub.4 which may be the same or different each represents a substituted or unsubstituted hydrocarbon group; or R.sub.3 and R.sub.4 taken together may represent an alkylene group or a hetero group having one or more hetero atoms and R.sub.5 is hydrogen, a substituted or unsubstituted hydrocarbon group, halogen or a free or protected hydroxy group, or a pharmaceutically acceptable salt thereof. The compounds have antiaggregating properties.
摘要:
The present invention relates to a method for preparing inner ester derivatives of gangliosides and pharmaceutical compositions containing such derivatives to be used in treating disorders of the nervous system. The pharmaceutical compositions of the present invention promote nerve regeneration by stimulating nerve sprouting.
摘要:
Two pharmaceutically useful fractions of hyaluronic acid are obtained comprising a first fraction with a molecular weight between 50,000 and 100,000 which is useful for wound healing, and a second fraction having a molecular weight between 500,000 and 730,000 which is useful for intraocular and intraarticular injections.In addition, pharmaceutical preparations for topical administration are provided containing a pharmacologically active substance together with hyaluronic acid or a molecular weight fraction thereof. The hyaluronic acid may be in the form of the free acid or may be a salt with an alkali or alkaline earth metal, magnesium, aluminum or ammonium, or in the form of a salt with one or more pharmacologically active substances.
摘要:
