Discovery of [1,2,4]triazolo[1,5-a]pyrimidine-Imatinib Hybrids With Selective Cytotoxic Activity: A Mechanistically Divergent Series From Direct BCR-ABL1 Inhibition

Novel hybrid compounds targeting leukemia cells offer a fresh chemical scaffold worth exploring in drug discovery pipelines.

Six novel imatinib-triazolopyrimidine hybrid compounds were synthesized and evaluated in BCR-ABL1-positive CML cells; compound 2a showed cytotoxic activity through an ABL1-independent mechanism, establishing a structurally distinct scaffold with potential as an antimyeloproliferative lead. This is early-stage medicinal chemistry with a long translational path.
