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

Alkylphosphocholines, and especially their main representative hexadecylphosphocholine (HPC), show high anticancer activity in methylnitrosourea (MNU)-induced autochthonous rat mammary carcinoma. The regression of MNU-induced rat mammary carcinoma during HPC treatment can be evaluated by computed tomography and sonography. This allows a

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

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
