| titleOfInvention | Acylated phospholipid drugs |
| abstract | This invention relates to a method for improving the efficiency of a drug containing a free carboxy group, the improvement comprising esterifying said carboxy group to the hydroxy group of the glycerol portion of a glycerolphospholipid ester having the formula:or pharmaceutically acceptable salts thereof wherein one of R1 and R2 is hydrogen and the other is hydrogen, a hydrocarbyl fatty acid acyl group having 4-26 carbon atoms or a hydrocarbyl heteroatom fatty acid acyl group having 3-25 carbon atoms, orandR is a naturally occurring polar head group characteristic of a glycerophospholipid isolated from endogenous sources;R3 is hydrogen or lower alkyl andR4 is hydrogen, hydrocarbyl containing from 1-18 carbon atoms in a principal chain and up to a total of 23 carbon atoms, said principal chain may contain 1-5 double bonds or 1-2 triple bonds; phenyl which may be unsubstituted or substituted with lower alkyl; naphthyl which may be unsubstituted or substituted with lower alkoxy; or R5ZR6;Z is O or S; R5 and R6 are independently a hydrocarbyl chain containing from 1-18 carbon atoms in the principal chain and up to a total of 23 carbon atoms, said chain may be completely saturated or may contain 1-5 double bonds or 1-2 triple bonds;and the sum of the carbon atoms in R3 and R4 does not exceed 23.This invention also relates to the compounds prepared therefrom as well as the use of the compounds to treat diseases in animals. |
