    摘要: The present invention relates to compounds, compositions and methods for the prevention or treatment of mycobacterium infections. The compounds are naturally occurring and synthetic biflavonoids, flavonoids, chalcones and chalcone like compounds. The compounds were screened for anti-mycobacterium activity. Of the compounds showing anti-mycobacterium activity, eight were identified as particularly potent, exhibiting greater than 90% inhibition of the growth of Mtb at a concentration of 12.5 &mgr;g/mL. The actual minimum inhibitory concentrations (MIC), defined as the lowest concentration inhibiting 99% of the inoculum, for the preferred compounds ranged from 6.8 to 48.3 &mgr;M.

    摘要: Robustaflavone, intermediates and analogues thereof and a method for synthesizing the same are provided. The method involves constructing apigenin ethers containing functionalities at the 6- and 3′-positions which could be cross-coupled using transition metal catalysis. The method also involves development of a regioselective iodination of an apigenin derivative at the 6-position, formation of an apigenin 3′-boronate using a palladium-catalyzed exchange of the corresponding 3′-iodide with a diboron reagent. Finally, Suzuki coupling to form the sterically congested 6-3′″ biaryl bond of robustaflavone provides access to the desired biflavanoid system. Robustaflavone intermediates and analogues may be used to prepare analogues of other biflavanoids such as hinokifavone, rhusflavone and succedaneaflavone.

    摘要: An efficient and scalable method is reported for the isolation of costatolide (2), an HIV-1-specific nonnucleoside reverse transcriptase inhibitor (NNRTI), from the latex of Calophyllum plants such as C. teysmannii var. inophylloide. An overall yield of 10.6% of costatolide, with a purity of 96%, was obtained by repetitive recrystallization of the latex from a single organic solvent after the oily material was removed by treatment with hexane. A second major component of the latex, soulattrolide (3), another HIV-1 NNRTI, was also isolated. Both compounds were characterized by spectroscopic and chromatographic analyses and their in vitro anti-HIV activities were also confirmed. The results suggest that sufficient supplies of costatolide can be obtained in a relatively low-cost manner from natural sources.
