Conformationally constrained 6‑aryl‑1‑(3,4,5‑trimethoxyphenyl)-1H-pyrazolo[3,4‑b]pyrazines as novel microtubule destabilizers: design, synthesis, and antitumor evaluation
Findings establish the pyrazolo[3,4‑b]pyrazine scaffold as a promising platform for microtubule‑targeting anticancer agents and identify 10t as a compelling lead for further development.
