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. Compound 10m displayed powerful synergistic anti-proliferation and pro-apoptotic effects when combined with asciminib, highlighting its potential as a promising lead for the development of potential BCR-ABL inhibitors.

Detection of Black Holes
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...
