Abstract: .alpha.-Tocopherylphosphocholine and salts thereof have been discovered to possess antiviral, anti-fungal, anti-inflammatory, PAF-antagonist, and ultra-violet radiation-blocking activities. The compound and salts have also been discovered to be capable of forming liposomes. The present invention thus provides methods of treating viral and fungal infections, inflammatory disorders and pathophysiological conditions due to PAF activity in a mammal by administering to the mammal .alpha.-tocopherylphosphocholine or a pharmaceutically acceptable salt thereof. The invention also provides pharmaceutical compositions comprising .alpha.-tocopherylphosphocholine or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier. Further, the invention provides liposomes which comprise .alpha.-tocopherylphosphocholine or a salt thereof as a structural component of the liposome bilayer.

Abstract: Retinoyl substituted glycerophosphoethanolamines are disclosed having the general Formula I: ##STR1## wherein one of A, B or C is a fatty ether substituent, one is a natural or synthetic retinoid ester substituent, and one is a phosphoethanolamine substituent, provided that A, B and C are each a different substituent. The optical and geometric isomers of compounds of Formula I and the pharmaceutically acceptable salts of the compounds, including the isomers, are also disclosed. The compounds (including the isomers thereof) and salts of the invention exhibit anti-tumor, anti-psoriatic and anti-inflammatory activities.

Abstract: .alpha.-tocopherolphosphocholine and salts thereof have been discovered to possess anti-viral, anti-fungal, anti-inflammatory and PAF-antagonist activities. The compound and salts have also been discovered to be capable of forming liposomes.

The invention also provides pharmaceutical compositions comprising .alpha.-tocopherolphosphocholine or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier. Further, the invention provides liposomes which comprise .alpha.-tocopherolphosphocholine or a salt thereof as a structural component of the liposome bilayer.

Abstract: Certain phosphoethanolamine conjugates of vitamin D compounds are disclosed wherein the phosphoethanolamine moiety is bonded at the 3-position of the vitamin D moiety. The conjugates exhibit anti-tumor, anti-psoriatic and anti-inflammatory activities in addition to those activities associated with vitamin D. The invention embraces the novel compounds, pharmaceutical compositions thereof, and their methods of use.
