  Synthesis and evaluation of novel ether lipid nucleoside conjugates for anti-HIV-1 activity

  摘要：

  Combinations of an amidoalkylphosphocholine, 8, and AZT have been found to cause an apparent synergistic action in suppressing infectious HIV-1 replication. In addition, amidoalkyl, oxyalkyl, and thioalkyl ether lipids have been chemically linked to anti-HIV-1 nucleosides (AZT and DDI) through phosphate and phosphonate linkages. These conjugates have shown promising in vitro anti-HIV-1 activity. Also, the conjugates have a 5-10-fold reduction in cell cytotoxicity compared to AZT alone. The most active compound, an amidoalkyl ether lipid-AZT conjugate, 4A, was found to have a differential selectivity of 1793 in a syncytial plaque assay. In comparison, AZT alone has a value of 1281.

  Synthesis and evaluation of neoplastic cell growth inhibition of 1-N-alkylamide analogs of glycero-3-phosphocholine

  摘要：

  Previously unreported analogues of the synthetic antitumor phospholipid ET-18-OMe (1-octadecyl-2-methoxy-rac-glycero-3-phosphocholine), in which the 1-ether oxygen has been replaced by an amido group, have been prepared and evaluated for in vitro cytotoxic effects and for inhibition of protein kinase C. The title compounds exhibit cytotoxic effects against several tumor cell lines and are approximately equipotent to ET-18-OMe. The compounds were also found to inhibit protein kinase C in an in vitro assay. This work is a continuation of our previous structure-activity studies on thio-substituted derivatives of ET-18-OMe.

  The oral route is the preferred route of delivery for a large number of drug molecules. However, the intestinal epithelium presents a formidable barrier for delivery of drugs into systemic circulation. Phospholipids are among compounds that enhance the absorption of drugs across the intestinal epithelium. In this paper, we describe structure-activity relationships for phospholipid derivatives as enhancers of paracellular permeability across Caco-2 cell monolayers. in a series of 2-alkoxy-3-alkylamidopropylphosphocholine derivatives, compounds with a long chain at C-3 (R-3) and short chain at C-2 (R-2) were potent in causing a decrease in transepithelial electrical resistance (TEER) and an increase in mannitol transport, but also showed significant cytotoxicity. Compounds with 9-11 carbons at C-3 and 6-10 carbons at C-2 provided good separation (up to 2.7-fold) between activity and cytotoxicity. Notably, a good correlation (r(2) = 0.93) was observed between EC50 (TEER) [concentration that caused a drop in TEER to 50% of its control (untreated) value] and EC10X (mannitol) [concentration that caused 10-fold increase in mannitol transport over the control (untreated) value], confirming that a decrease in TEER is associated with enhanced permeability of the hydrophilic compounds across Caco-2 cell monolayers. Compounds with medium to long carbon chains at C-2 and C-3, and the total carbons in the alkyl chains > 20, showed poor activity and no cytotoxicity.
