A new method for the synthesis of the cardiolipin family of phospholipids which are characteristically located at the inner membrane of mitochondria, and particularly abundant in the heart, is described in this paper. A 1,2-diacyl-sn-glycerol, derived from stearic, palmitic, or myristic acid, is converted into the corresponding 1',3'-diphosphatidylglycerol (DPG), by means of the phosphorylating reagent

This invention has for its object to insure an effective utilization of single-stranded nucleic acid copolymers, particularly poly(adenylic acid-uridylic acid), and to provide a pharmaceutical composition having antitumor activity. The invention typically relates to a pharmaceutical composition comprising a lipid device such as Lipofectin (trademark), 3-O-(4-dimethylaminobutanoyl)-1,2-O-dioleylgycerol, 3-O-(2-dimethylamino-ethyl)carbamoyl-1,2-O-dioleylglycerol, 3-O-(2-diethylaminoethyl) carbamoyl-1,2-O-dioleylgycerol, or 2-O-(2-diethylaminoethyl)carbamoyl-1,3-O-dioleoylglycerol and poly(adenylic acid-uridylic acid).
enantioselective acylative desymmetrization of glycerol was developed by using a chiral DMAP derivatives 1e having a 1,1ʹ-binaphthyl unit. The reactions required only 0.1 mol% of the catalyst and showed moderate to good enantioselectivity (up to 94:6 er). Control experiments revealed that the first acylation of a glycerol derivative proceeded selectively rather than the second acylation to give diacylate.
