ABSTRACT:
This invention pertains to the synthesis and use as therapeutic agents of a group of substances with a glycerol backbone or aliphatic chain structure linked to a phosphorus atom and a polar head group. Depending on the polar head group, the substance has anti-cancer, anti-inflammatory, anti-allergy or anti-cardiovascular disease properties. Compounds of the formula: ##STR1## wherein n is 0 to 14 and R.sub.1 is an alkyl group of C.sub.12 -C.sub.20, R.sub.2 is a methyl group, and wherein R.sub.3 is an inositol analog head group, a (CH.sub.2).sub.m N.sup.+ (CH.sub.3).sub.3 group with m=2 to 10, a serine head group, or an ethanolamine head group, or of the formula ##STR2## wherein R.sub.1 and R.sub.2 are as described above, n=0 or 1, and R.sub.3 is (CH.sub.2).sub.m N.sup.+ (CH.sub.3).sub.3 (m=2-10 ) are claimed. This invention also pertains to the synthesis and use as therapeutic agents of a group of substances that have no glycerol backbone but have an aliphatic chain structure linked directly to a phosphorus atom of the general formula R--P(O)(O-)OR' wherein R is a long-chain alkyl group such as hexadecyl or octadecyl and R' is a head group such as choline, glycerol, inositol, ethanolamine, or serine.
