The first synthetic route developed for Podocarflavone A reported from Podocarpus macrophyllus and its analogs in 7 steps. Computational analysis for binding with the pantothenate kinase (3AVO) of Mycobacterium tuberculosis showed their docking score (ds) in the range of ?8.9 to ?9.3 Kcal/mol. MD simulations delineated the stability of the protein-ligand complexes in the TIP3P model. MMGBSA and MMPBSA values of 8d were ?42.46 Kcal/mol and ?14.58 Kcal/mol, respectively. Further in-vitro antitubercular screening of compounds 8a, 8d, and 8e against M. tuberculosis H37Ra using XRMA protocol exhibited promising antimycobacterial activity with IC50 values 21.82μg/mL, 15.55 μg/mL, and 16.56 μg/mL, respectively. Compounds 8a, 8d, and 8e showed antibacterial activity with IC50 values 41.56 μg/mL, 24.72 μg/mL, and 72.45 μg/mL respectively against the Staphylococcus aureus. 8a and 8d showed inhibition with IC50 values 39.6 μg/mL and 27.64 μg/mL, respectively, against Bacillus subtilis. The present study could help in the further development of lead molecules against tuberculosis.

Novel series of chalcones were synthesized and were evaluated as possible anti-inflammatory agents targeting the cyclooxygenase-1 and 2 (COX-1 and 2), β-glucuronidase, trypsin, and TNF-α. Amongst the tested chalcones the compound 4k was found to be most effective inhibitor of TNF-α exhibiting 85% inhibition activity (IC50 = 0.1 μM). The compounds 4a, 4f, 4l, and 4m were found to inhibit the COX-1 activity in as a range of 79.95-68.47% and COX-2 inhibition ranging 84.45-74.77%. The compounds 4l (81.71%) and 4f (72.10%) were found to be excellent inhibitors of trypsin and β-glucuronidase, respectively. Springer Science+Business Media, LLC 2011.
Regioselective monobromination of (E)-1-(2′-hydroxy-4′, 6′-dimethoxyphenyl)-3-aryl-2-propen-1-ones using bromodimethylsulfonium bromide and synthesis of 8-bromoflavones and 7-bromoaurones

A wide variety of monobrominated compounds 2a-l have been prepared in good yields from (E)-1-(2′-hydroxy-4′,6′-dimethoxyphenyl)-3-aryl-2- propen-1-ones (1a-l) through regioselective ring bromination using 1.5 equiv of bromodimethylsulfonium bromide (BDMS)

Chagas' disease, a parasitic infection widely distributed throughout Latin America, is a major public health problem with devastating consequences in terms of human morbidity and mortality. The enzyme cruzain is the major cysteine protease from Trypanosoma cruzi, the etiologic agent of American trypanosomiasis or Chagas' disease, and has been selected as an attractive target for the development of novel trypanocidal drugs. In the present work, we describe the synthesis and inhibitory effects of a series of thirty-three chalcone and seven hydrazide derivatives against the enzyme cruzain from T. cruzi. Most of the compounds showed promising in vitro inhibition (IC50 values in the range of 20-60 μM), which suggest the potential of these compounds as lead candidates for further development. Twelve compounds have not been reported before, and four of them (7, 13, 16 e 18) are among the most potent inhibitors of the series.

Searching for leading compounds of new drugs for cancer therapy, we studied the toxicity of 13 hydroxychalcones never tested before toward melanoma cell line (B16-F10). The compounds were obtained by aldolic condensation between aldehydes and hydroxylated

(matrix presented) Vanadium pentoxide very effectively promotes the bromination of organic substrates, including selective bromination of some aromatics, by tetrabutylammonium bromide in the presence of hydrogen peroxide; mild conditions, high selectivity, yield, and reaction rate, and redundancy of bromine and hydrobromic acid are some of the major advantages of the synthetic protocol.
