Glycosylated antitumor ether lipids (GAELs), analogs of 1-O-octadecyl- 2-O-methyl-sn-glycero-3-phosphocholine (1, ET-18-OCH3, edelfosine), were synthesized in good overall yields by glycosylation of 1-O-alkyl-2-O- methyl-sn-glycerol and tested for in vitro antineoplastic activity against a variety of murine and human tumor cell lines. Stereospecific glycosylation was achieved by the use of 2-O-acetyl-3,4,6-tri-O-benzylglucopyranosyl and - mannopyranosyl trichloroacetimidates as donors, with trimethylsilyl trifluoromethanesulfonate as catalyst in the presence of molecular sieves at -78 °C. The GAELs differ from 1 in having the sn-3-phosphocholine residue replaced by one of the following monosaccharide residues: β- and α-2- deoxy-D-arabino-hexopyranosyl, α-D-mannopyranosyl, 2-O-methyl-β-D- glucopyranosyl, and 2-O-methyl-α-D-mannopyranosyl. 1-O-Hexadecyl-2-O- methyl-3-O-(2'-deoxy-β-D-arabino-hexopyranosyl)-sn-glycerol (2) was more effective than 1 in inhibiting the growth of MCF-7 (human breast cancer) and its adriamycin-resistant form MCF-7/adriamycin, and murine Lewis lung cancer cells. 2-Deoxy-β-D-arabino-hexopyranoside 2 was also an effective growth inhibitor of two drug-resistant leukemic cell lines, P388/Adr and L1210/vmdr.
