A synthetic alternative to natural lecithins with antimicrobial properties.
Two soft biocompatible cationic surfactants from the amino acid arginine, 1,2-dilauroyl-3-acetylarginyl-rac-glycerol (1212RAc) and 1,2-dimirystoyl-3-acetylarginyl-rac-glycerol (1414RAc), were prepared. Their physicochemical properties show that they can be classified as multifunctional surfactants with self-aggregation behaviour comparable to that of short-chain lecithins. The two surfactants c...
متن کاملDiether Analogues of Lecithins
Considerable interest has developed recently in naturally occurring phosphatides containing ether groups. Two classes of ether-containing phosphatides can be envisaged, i.e. monoether, monoester phosphatides, and diether phosphatides. To date, t,he only monoether, monoester phosphatides known to occur naturally are analogues of phosphatidylethanolamine (1-4) and phosphatidylcholine (5, 6). A ch...
متن کاملSaturated synthetic lecithins in VDRL and Kolmer antigens for the sero-diagnosis of syphilis.
When pure individual synthetic lecithins became available for study (Baer and Kates, 1949, 1950), there was immediate interest in their possible use in cardiolipin antigens as substitutes for Pangborn lecithin. Rosenberg (1949) reported briefly on synthetic L-c-(dipalmitoyl)-lecithin in antigens for the Hinton, Kline, Rein-Bossack, VDRL, and Kolmer tests. He found that replacement of Pangborn's...
متن کاملThe fractionation of lecithins and cephalins.
The lecithins and cephalins are complex mixtures of chemical entities differing from each other (a) in their component fatty acids, (h) in the case of the cephalins, in the nitrogenous constituent, and (c) in the point of substitution of t.he phosphoric acid-base group in the molecule. Power and Tutin (I) were the first to question the uniformity of the glycerophosphoric acids of lecithin. In 1...
متن کاملMetabolic heterogeneity of lecithins in intestine.
The incorporation of [2-3H]glycerol and lysolecithin labeled with [2-3H]glycerol into lecithin and its subspecies was investigated in epithelial and muscular layers of rat small intestine. The labeled compounds were administered in two wways: the intraduodenal injection and the injection into femoral vein. The incorporation of glycerol into lecithin was distinctly higher in epithelial layer tha...
