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-α 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-α and 70-93% IL-6 inhibitory activity) at concentration of 10 μM with reference to standard dexamethasone (71% TNF-a and 84% IL-6 inhibitory activities at 1 μM) while the compounds 5b, 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 μg/mL.

A series of 2-styrylchromone analogs were synthesized and examined for their antiproliferative effects on a panel of carcinoma cells. Among the tested agents, only 4m exhibited a moderate activity with an IC50 value of 28.9 μM against PC-3 cells which indicates the selectivity of PC-3 cells in response to 2-styrylchromones. In addition, 4q demonstrated the most antiproliferative effect with an IC50 value of 4.9 μM against HeLa cells. Flow cytometric analysis and DAPI staining revealed that HeLa cells exposed to 4q as low as 5 μM induced cell death through sub-G1 arrest and DNA fragmentation. Furthermore, CoMFA analysis of tested 2-styrylchromones resulted in a q2 of 0.459 to generate a 3D-QSAR model on BT483 cell line. Together, these results suggest a potential structural optimization and pharmacological study of 2-styrylchromones.
