Application

Antitumor phospholipid, induces apoptosis in three human leukemic cell lines.

Biochem/physiol Actions

C18-phosphocholine was the most potent alkylphosphocholine tested in inhibiting phosphatidylcholine biosynthesis. The effect is mediated by interrupting the translocation of the rate-limiting enzyme, CTP:phosphocholine cytidylyltransferase, to membranes, where it is active.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Anti-cancer drugs, 2(4), 411-417 (1991-08-01)
Hexadecylphosphocholine (HPC) and its analogs with a longer alkyl chain (C18 and C20) were examined for antineoplastic activity in the murine tumor models P388 leukemia, B 16 melanoma, the mammary carcinoma C3H and Ca 755, and the human MT-1 mammary
V Brochez et al.
Lipids, 34(5), 511-516 (1999-06-24)
The determination of cellular content of octadecylphosphocholine (D-19391) and hexadecylphosphocholine (HePC, D-18506), two anticancer agents of the alkylphosphocholine group, using capillary gas chromatography is described. The compounds' cytotoxicity was first determined by the MTT [3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium] assay, being indicative for the
M K Jain et al.
Biochimica et biophysica acta, 813(1), 68-76 (1985-02-28)
Properties of the aqueous dispersions of n-octadecylphosphocholine are examined by differential scanning calorimetry, fluorescence depolarization, light scattering, 31P-NMR, pig pancreatic phospholipase A2 binding, and X-ray diffraction. On heating, these dispersions exhibit a sharp lamellar to micelle transition at 20.5 degrees

At least 50% of the major axonal membrane lipid, phosphatidylcholine, of rat sympathetic neurons is synthesized in situ in axons [Posse de Chaves, Vance, Campenot and Vance (1995) J. Cell Biol. 128, 913-918]. In the same study we reported that
N Dittrich et al.
Journal of enzyme inhibition, 11(1), 67-75 (1996-08-01)
Alkylphosphate esters were shown to be potent inhibitors of phospholipase D. Using phosphatidyl choline/sodium dodecylsulfate (2:1) as substrate, IC50 values were determined for alkylphosphocholines of different chain length (C10-C18) and for various octadecylphosphate esters with different polar head groups.
