Novel 3-(1-acetyl-5-(substituted-phenyl)-4,5-dihydro-1H-pyrazol-3-yl)-7-fluoro-2H-chromen-2-one Derivatives: Synthesis and Anticancer Activity
A series of novel coumarin derivatives containing 4,5-dihydropyrazole moiety as potential telomerase inhibitors were synthesized. The bioassay tests showed that compound 3b exhibited potentially high activity against human gastric cancer cell SGC-7901 with IC50 value was 2.98±0.16. Docking simulation was performed to position compound 3b into the telomerase (3DU6) active site to determine the probable binding model. The result shows that some coumarin containing 4,5-dihydropyrazole moiety can combine well with the telomerase active site and may have use as potential telomerase inhibitors.
