Ehrlich ascites tumor cells were incubated in vitro with rac-1-O-[1'-14C]octadecyl-2-O-methylglycero-3-beta-D-glucopyranosi de for 24 h. The potentially antineoplastic ether glycolipid was rapidly metabolized by the cells to radioactive 1-O-octadecyl-2-O-methylglycerol (70 pmol/10(6) cells per h) and further acylated to 1-O-octadecyl-2-O-methyl-3-acylglycerols. Incubation of Ehrlich ascites cells with synthetic rac-1-O-[1'-14C]octadecyl-2-O-methyl-3-palmitoylglycerol showed that this metabolite is reconverted by deacylation to 14C-labeled 1-O-octadecyl-2-O-methylglycerol. The latter compound or a metabolite derived therefrom may be the 'toxic principle' of both the ether glyceroglycolipids and ether glycerophospholipids having a 1-O-alkyl-2-O-methylglyceryl moiety, as suggested by Unger et al. (J. Natl. Cancer Inst. 78 (1987) 219-222).

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D010742	Phospholipid Ethers	Phospholipids which have an alcohol moiety in ethereal linkage with a saturated or unsaturated aliphatic alcohol. They are usually derivatives of phosphoglycerols or phosphatidates. The other two alcohol groups of the glycerol backbone are usually in ester linkage. These compounds are widely distributed in animal tissues.
