title: Synthesis of 2-styrylchromones as a novel class of antiproliferative agents targeting carcinoma cells.
abstract: 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 IC(50) value of 28.9 microM 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 IC(50) value of 4.9 microM against HeLa cells. Flow cytometric analysis and DAPI staining revealed that HeLa cells exposed to 4q as low as 5 microM induced cell death through sub-G1 arrest and DNA fragmentation. Furthermore, CoMFA analysis of tested 2-styrylchromones resulted in a q(2) 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.
