摘要:
invention relates to heterocyclic phospholipids of formula III which are useful in treating multiple sclerosis:where R .sub.2 is n-C.sub.14 -C.sub.20 alkyl;each R.sub.1, independently, is methyl or ethyl; Y is --O-- or --S--;n is an integer 2 to 6.

摘要:
Bis-substituted benzyl acetic acids, e.g., bis-(p-pivaloylbenzyl)acetic acid, are prepared by hydrolyzing and decarboxylating a corresponding bis-(p-pivaloylbenzyl)malonic acid diethyl ester and are useful as hypolipidemic agents.
摘要:
Hydroxyalkyl and aryl or heterocyclic substituted-4,5-dihydropyridazin(2H)-3-ones and diazabicyclo-ene-ones e.g., 6-(p-chloro-phenyl)-2-(2-hydroxybutyl)-4,5-dihydropyridazin(2H)-3-one are prepared by condensing 1-hydrazino-2-alkanols with aryl or heterocyclic-.gamma.-keto acids and are useful as central nervous system depressants.
