Synthesis, single-crystal characterization and preliminary biological evaluation of novel ferrocenyl pyrazolo[1,5-a]pyrazin-4(5H)-one derivatives

A series of novel ferrocenyl pyrazolo[1,5–a]pyrazin-4(5H)-one derivatives was synthesized and characterized by 1H NMR, 13C NMR, IR, HRMS and X-ray diffraction analysis. Preliminary evaluation of biological applications showed that the compounds 6c and 6f inhibit the growth of A549 cells in dosage-dependent manners through cell cycle arrest.
