A facile methodology powerful in obtaining a set of compounds sellekchem monofluorinated at different positions (fluorine scan) by chemical synthesis is reported. Direct and nonselective fluorination reactions of our lead compound la and essential intermediate 2a worked efficiently Ferroptosis to afford a complete of six monofluorinated derivatives. All of the derivatives kept their physicochemical properties compared with all the lead la and one of them had enhanced Raf/MEK inhibitory exercise. Maintaining physicochemical properties may be regarded as a benefit of monofluorinated derivatives in contrast with chlorinated derivatives, iodinated derivatives, methylated derivatives, and so forth. This critical discovering led towards the identification of compound 14d, which had potent tumor growth inhibition in a xenograft model, superb PKselleck profiles in 3 animal species, and no significant toxicity.
