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

Journal of medicinal chemistry, 48(20), 6393-6399 (2005-09-30)
Alkylphospholipid analogues of perifosine and miltefosine bearing a nitroxide moiety at different positions on an alkyl chain were synthesized as electron paramagnetic resonance (EPR) probes. Their amphiphilic properties were characterized by determining their critical micelle concentration (cmc) and hemolytic activity

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.
