Discovery of <i>N</i>-(2-Acetamidobenzo[<i>d</i>]thiazol-6-yl)-2-phenoxyacetamide Derivatives as Novel Potential BCR-ABL1 Inhibitors Through Structure-Based Virtual Screening.

ABSTRACT: BCR-ABL1 kinase is a critical driver of chronic myeloid leukemia (CML) pathophysiology. The approval of allosteric inhibitor asciminib brings new hope for overcoming drug resistance caused by mutations in the ATP-binding site. To expand the chemical diversity of BCR-ABL1 kinase inhibitors with positive anti-tumor effect with asciminib, structure-based virtual screening and molecular dynamics simulations were employed to discover novel scaffolds. This approach led to the identification of a series of N-(2-acetamidobenzo[d]thiazol-6-yl)-2-phenoxyacetamide derivatives as new BCR-ABL1 inhibitors. The most potent compound, 10m, demonstrated inhibition of BCR-ABL-dependent signaling and showed an anti-tumor effect against K562 cells, with an IC₅₀ value of 0.98 μM.
