Kava analogues as agents for treatment of periodontal diseases: Synthesis and initial biological evaluation
摘要:
Six kava analogues of the structural type 3-oxocyclohex-1-en-1-yl benzoates (and corresponding benzamides) were synthesized and evaluated for their affect on periodontal deconstruction in collagen anti-body primed oral gavage model of periodontitis. The compounds were prepared through an acylation or amidation of the enolizable cyclic 1,3-diketone. We have learned that three of the analogues are responsible for the reduction of inflammatory cell counts within soft tissue. These novel kava-like molecules where the lactone is replaced by an alpha,beta-unsaturated ketone show promise in the prevention and treatment of inflammation and alveolar bone loss associated with periodontitis.

Structure-activity relationship studies were employed to synthesize a series of 3- and 3,4-substituted benzamides from 3-amino-2-cyclohexenones. An improved method for the synthesis of benzamides from 3-amino-2-cyclohexenones is presented which provided significantly higher yields (71-79%) for the reported compounds. NMR and X-ray structural analyses were undertaken to note the possible intra- and intermolecular

A comparison of enaminones from various unsubstituted and p-substituted benzamides to the analogous benzylamines has been undertaken with the aim of elucidating the essential structural parameters necessary for anticonvulsantactivity. Initial studies on methyl 4-N-(benzylamino)-6-methyl-2-oxocyclohex-3-en-1-oate, 3a, 3-N-(benzylamino)cyclohex-2-en-1-one, 3p, and 5,5-dimethyl-3-N-(benzylamino)-cyclohex-2-en-1-one
