  Synthesis and biological evaluation of novel piperazine derivatives of flavone as potent anti-inflammatory and antimicrobial agent

  摘要：

  A series of novel 6-methoxy-2-(piperazin-1-yl)-4H-chromen-4-one and 5,7-dimethoxy-2-(piperazin-1-ylmethyl)-4H-chromen-4-one derivatives of biological interest were prepared and screened for their pro-inflammatory cytokines (TNF-alpha and IL-6) and antimicrobial activity (antibacterial and antifungal). Among all the compound screened (5a-j and 10k-t), the compounds 5c, 5g, 5h, 10l, 10m, 10n and 10r found to have promising anti-inflammatory activity (up to 65-87% TNF-alpha and 70-93% IL-6 inhibitory activity) at concentration of 10 mu M with reference to standard dexamethasone (71% TNF-a and 84% IL-6 inhibitory activities at 1 mu M) while the compounds5b, 5i, 5j, 10s and 10t found to be potent antimicrobial agent showing even 2 to 2.5-fold more potency than that of standard ciprofloxacin and miconazole at the same MIC value of 10 mu g/mL.

• Syntheses and Evaluation of 2- or 3-(<i>N</i>-Cyclicamino)chromone Derivatives as Monoamine Oxidase Inhibitors

  A series of 2-(N-cyclicamino)chromone derivatives (1a-4c) and 3-(N-cyclicamino)chromone derivatives (5a-8c) were synthesized, and their monoamine oxidase (MAO) A and B inhibitory activities were studied as part of a structure-activity relationship investigation. Compounds 1a-4c showed no remarkable inhibition for MAO-A or MAO-B, whereas compounds 5a-8c (with a few exceptions) showed significant and selective inhibition of MAO-B. Of these compounds, 7c,7-methoxy-3-(4-phenyl-1-piperazinyl)-4H-1-benzopyran-4-one inhibited MAO-B the most potently and selectively, having IC50 of 15 nM and an MAO-B selectivity index of more than 6700; c.f, 50 nM and 2000, respectively, for safinamide. The mode of inhibition of 7c to MAO-B was competitive and reversible. Considering the IC50 values and selectivity indices of the other synthetic compounds, the presence of the methoxy group on the chromone ring (R-2) of 7c seemed to increase MAO-B inhibition. Molecular docking analysis also supports this hypothesis. Our results suggest that 3-(N-cyclicamino)chromones are useful lead compounds for the development of MAO-B inhibitors.
