摘要:
Triterpene saponins of formula ##STR1## wherein R.sub.1 is H or OH and R.sub.2 is a tetrasaccharide, or alternatly pentasaccharide, chain have antiinflammatory, mucolytic and antiedemic activities. Said saponins are isolated from roots and bark of Crossopteryx febrifuga, for instance by precipitating them, in form of a complex with cholesterol or sytosterol, from an alcoholic extract of the vegetal material and by partitioning the precipitate between an apolar solvent, which subtracts the complexing agent and a polar solvent in which saponins are soluble.
摘要:

摘要:
Derivatives of pyrrolo[2,1-b]benzothiazepines with formula (I) where A is CH—CH2C═CH; R is hydrogen, halogen, C1-C4 alkoxy, C1-C4 alkylthio, C1-C4 alkyl, C5-C6 cycloalkyl; R1 is 1-peperazinyl, 1-homopiperazinyl and 1-piperidinyl; R2 is hydrogen, C1-C4 alkoxy, C1-C4 alkylthio, C1-C4 alkyl, CHO, CH═NOH,CH2OH. The formula (I) compounds are endowed with characteristic atypical anti-psychotic activity, and are therefore useful as medicaments, in particular for the treatment and prevention of schizophrenia, paranoid states, manic-depressive states, disorders of the affective sphere, social regression, personality regression, and hallucinations. Said compounds also present advantageous pharmacokinetic properties.
