  Structure−Activity Relationship for Enhancement of Paracellular Permeability across Caco-2 Cell Monolayers by 3-Alkylamido-2-alkoxypropylphosphocholines

  摘要：

  Paracellular permeability enhancers have been used to improve the oral bioavailability of hydrophilic drugs; however, the mechanism of action of many enhancers is poorly understood. In this study, highly potent enhancers of paracellular permeability were identified in the 3-alkylamido-2-alkoxypropylphosphocholine series, and a structure-activity relationship was developed for enhancement of paracellular permeability across Caco-2 cell monolayers. Compounds with short (<5 carbons) hydrocarbon chains at both C-2 and C-3 were generally inactive. The potency exhibited a parabolic relationship with respect to the chain length at either C-2 or C-3. Linear molecules (i.e., compounds with a short hydrocarbon chain at C-2 or C-3 and a long hydrocarbon chain on C-3 or C-2, respectively) were more potent than the corresponding branched molecules with the same carbon load. The efficacy of 3-alkylamido2-alkoxypropylphosphocholines as enhancers of paracellular permeability was not dependent on their existence in micellar form or their ability to alter the fluidity of cell membrane. Previously, a correlation-between the potency of alkylphosphocholines as enhancers of paracellular permeability and the inhibitors of phospholipase C (PLC) was established in Madine Darby canine kidney (MDCK) cell monolayers. The potencies of selected 3-alkylamido-2-alkoxypropylphosphocholines as inhibitors of PLC and enhancers of paracellular permeability fit well into this correlation. Therefore, phosphocholines are likely to increase paracellular permeability by modulating the signal transduction pathway initiated by a PLC-catalyzed reaction rather than by physically altering the cell membrane.

  methyl decreased activity slightly. In the nonphosphorus compounds, many nitrogen heterocycles and also a sulfonium moiety were incorporated without changing the degree of activity; however, a thiazolium group decreased activity. The most active compound, 29 [N-[3-(hexadecyloxy)-2-methoxypropyl]-3-(hydroxymethyl)pyridinium bromide], was approximately twice as active as the reference standard, ET-18-OMe

  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antitumor phospholipid ET-18-OMe (1-octadecyl-2-methoxy-rac-glycero-3-phosphocholine), in which the 1-ether oxygen has been replaced by an amido group, have been prepared and evaluated for in vitro cytotoxic effects and for inhibition of protein kinase C. The title compounds exhibit cytotoxic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.
