This paper presents synthesis and structure–activity relationship of pyridine derivatives as inhibitors of mutant isocitrate dehydrogenase 2 ( IDH 2). A series of 2,4,6‐trisubstituted pyridine derivatives have been prepared and evaluated in vitro. Among these compounds, 14n exhibited excellent inhibition activity with the IC 50 of 54.6 n m , which is approximately onefold improvement compared to drug candidate AG ‐221 (Enasidenib) that is in Phase III trial. Exquisite selectivity of 14n for IDH 2 R140Q mutant isoform was demonstrated by the poor activity against the wild‐type IDH 1 and IDH 2.
