The invention discloses certain heterocyclic, thioether, keto-ester and alkyl phospholipids, e.g., heterocyclic phospholipids having the formula (* CHEMICAL STRUCTURE *) where R is n-C14-C20alkyl or O-n-C14-C20alkyl; each R1 is methyl or ethyl; n is 2-6; and X is -CH2-m, where m is 2-4, CH2CH2O or CH2CH2S, or a corresponding hydrate thereof, which compounds are useful in treating multiple sclerosis.
