To change the pharmacokinetic properties of the known antitumor agents
sarcolysine, rubomycin, and methotrexate, their lipid derivatives wer
e synthesized with the residues of rac-1,2-dioleoylglycerol and heptad
ecyl alcohol. An ether lipid analog, 3-sarcolysyl 2-methyl-1-octadecyl
-sn-glycerol, with the lipid moiety being itself an antineoplastic age
nt was also obtained.
