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.
