abstract::New antitumor alkylglycerophospholipids, in which primarily the phosphocholine moiety of the platelet activating factor (PAF) molecule was modified, were synthesized from 1-alkyl-2-substituted glycerols by introducing polar head phosphoryl groups having methylene bridges of various lengths (from 2 to 14 carbons). They...

abstract::The inhibitory effects of pure galloylglucose (1,2,3,4,6-penta-O-galloyl-beta-D-glucose) on the respiratory chain of rat liver mitochondria were investigated. The respiratory control ratio (RCR) decreased by 50% on addition of 20 microM pentagalloylglucose to highly coupled mitochondria, but the adenosine-5'-diphospha...
