  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.

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antitumor phospholipid ET-18-OMe (1-octadecyl-2-methoxy-rac-glycero-3-phosphocholine), in which the 1-ether oxygen has been replaced by an amido group, have been prepared and evaluated for in vitro cytotoxic effects and for inhibition of protein kinase C. The title compounds exhibit cytotoxic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