  Synthesis and evaluation of new chalcones, derived pyrazoline and cyclohexenone derivatives as potent antimicrobial, antitubercular and antileishmanial agents

  摘要：

  A series of chalcones (1-8) were prepared by Claisen-Schmidt condensation of 3-nitroacetophenone with various aldehydes. These chalcones on cyclization with hydrazine hydrate in the presence of glacial acetic acid, hydrazine hydrate in absolute ethanol and ethyl acetoacetate in the presence of barium hydroxide gave corresponding N-acetyl pyrazolines (9-16), N-unsubstituted pyrazolines (17-19) and cyclohexenone derivatives (20-22). All the synthesized compounds were evaluated for their in vitro antibacterial and antifungal activity by using broth microdilution method, and many compounds showed promising activity against various tested bacteria and fungi. Among various tested compounds, 16 and 19 exhibited strongest activities against Streptococcus pyogenes and Pseudomonas aeruginosa; both have MIC value of 25 mu g/mL, which is fourfold greater than the standard drug. Many compounds showed good activity against Candida albican. Analogs 11, 12, 15-17 and 19 displayed two- to fivefold greater activity against C. albican as compared to the standard drug. Results of antitubercular evaluation revealed that compounds 4 and 19 displayed strong antimycobacterial activity against H(37)Rv having MIC of 25 and 62.5 mu g/mL, respectively. All analogs were found to be inactive against Leishmania braziliensis except analogs 4 and 5 which exhibited strong leishmanicidal activity against Leishmania promastigotes with IC50 values of 9.3 and 8.9 mu g/mL, respectively.

  Synthesis, anticancer and antioxidant activities of 2,4,5-trimethoxy chalcones and analogues from asaronaldehyde: Structure–activity relationship

  摘要：

  2,4,5-Trimethoxy chalcones and analogues were synthesized from asaronaldehyde derived from beta-asarone. These novel compounds when tested against three human tumour cell lines (MCF-7, SW-982 and HeLa) using MTT assay, revealed that chalcones possessing electron donor groups in para position to carbonyl moiety of phenyl ring A, showed better inhibitory activity (2, 3, 4, 6, 7, 10, 17). When evaluated for antioxidant activities, compound 15 exhibited better free radical scavenging property in DPPH assay while compounds 2, 3, 5, 7, 9, 10, 11, 16, and 18 showed significant NO scavenging activity. All compounds exhibited very good phenyl hydrazine induced haemolysis of erythrocytes in phenylhydrazine assay. Structure activity relationship (SAR) study using in-silico analysis matched well with in-vitro tumour cell inhibitory activity. (C) 2013 Elsevier Masson SAS. All rights reserved.

  Falcipain-2 (FP-2) is a key cysteine protease from the malaria parasite Plasmodium falciparum. Many previous studies have identified FP-2 inhibitors; however, none has yet met the criteria for an antimalarial drug candidate. In this work, we assayed an in-house library of non-peptidic organic compounds, including (E)-chalcones, (E)-N'-benzylidene-benzohydrazides and alkylesters of gallic acid, and assessed the activity toward FP-2 and their mechanisms of inhibition. The (E)-chalcones 48, 54 and 66 showed the lowest IC50 values (8.5 +/- 0.8 mu M, 9.5 +/- 0.2 mu M and 4.9 +/- 1.3 mu M, respectively). The best inhibitor (compound 66) demonstrated non-competitive inhibition, and using mass spectrometry and fluorescence spectroscopy assays, we suggest a potential allosteric site for the interaction of this compound, located between the catalytic site and the hemoglobin binding arm in FP-2. We combined structural biology tools and mass spectrometry to characterize the inhibition mechanisms of novel compounds targeting FP-2.
