Toward the development of chemoprevention agents. Part II: Chemo-enzymatic synthesis and anti-inflammatory activities of a new class of 5-amino-2-substitutedphenyl-1,3-dioxacycloalkanes
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.
Toward the development of chemoprevention agents. Part 1: Design, synthesis, and anti-inflammatory activities of a new class of 2,5-disubstituted-dioxacycloalkanes
A newclass of 2,5-disubstituted-dioxacycloalkanes were designed and synthesized via stereoselective synthetic method as cancer chemoprevention agents. The anti-inflammatory activities of these compounds were tested using the xylene-induced mouse ear edema model. Some of these compounds exhibited comparable or better anti-inflammatory activities than that of aspirin suggesting that they can be further

The present invention discloses a series of benzoylamino-1,3-dioxacyclane compounds, of which compounds 1-21 were prepared via transacetalisation reaction between N-benzoylaminoglycol and 1,1,3,3-tetramethoxypropane; while compounds 22-48 were prepared via stereospecific acetalisation reaction between N-benzoylamino glycol and aromatic aldehyde, and if necessary, the nitro groups were reduced and further be salified with propane diacid and L-Arg or L-Lys. These compounds possess the structural type of PKC inhibitor and positive anti-inflammatory effect, and can be applied in medical fields as PKC inhibitor for corresponding therapy.
