A new series of optically pure 5-amino-2-substitutedphenyl-1,3-dioxacyclozilkanes were designed and synthesized via a chemo-enzymatic combined method to develop new chemoprevention agents. Twenty-four of newly synthesized compounds significantly inhibited xylene-induced rat ear edema and exhibited comparable or better anti-inflammatory activities than the reference drug aspirin. Treatment of these anti-inflammatory agents did not prolong the tail bleeding time in rat. In addition, 5-amino-2-substitutedphenyl- I 3-dioxacycloalkanes exhibited good membrane permeability based on in vitro Caco-2 cell monolayer permeability assay. Furthermore, some preliminary structure-activity relationships were further analyzed among these compounds. Taken together, 5-amino-2-substitutedphenyl-1,3-dioxacycloalkanes may represent a new class of anti-inflammatory drugs with safer pharmacological profile. (c) 2007 Elsevier Ltd. All rights reserved.
