A synthetic benzoxazine dimer derivative targets c-Myc to inhibit colorectal cancer progression. [PDF]

open access: yesMol Oncol
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.
