摘要:
Phosphatidylinositol of high purity useful for the treatment of central nervous system disorders, prepared from vegetal substances containing it by treating them with reagents suitable for the functionalization of the inositol hydroxy group with protective groups, separating the thus protected phosphatidylinositol by solvent extraction or chromatography, and finally removing said protective groups under conditions which do not modify the phosphatidyl group.

摘要:
A process for preparing pyrido-benzothiazine derivatives having the following general formula: ##STR1## in which R is H or a C.sub.1 -C.sub.6 alkyl or a C.sub.1 -C.sub.6 fluoroalkyl, and R.sub.1 is N-alkyl-3-pyrrolidinalkylamine with C.sub.1 to C.sub.6 alkyls or ##STR2## where R.sub.2 is a C.sub.1 -C.sub.6 alkyl or a C.sub.2 -C.sub.6 alkenyl or an arylalkyl group, possibly substituted by halogen, hydroxy or keto-groups, both in the racemic form and in the optically active form. The process for the preparation of derivatives of formula (I) starts with a first reaction cycle starting from 2,4-difluoro-3-chloronitrobenzene. Said derivatives possess a high antibacterial activity as well as a high bioavailability to tissues. The invention also refers to pharmaceutical compositions containing them as active components.
