2-Substituted 3-aroylquinolin-4(1H)-ones, prepared through a palladium-catalyzed carbonylative cyclization of N-(2-iodoaryl)enaminones, proved to inhibit efficiently the Hedgehog pathway through direct antagonism of the wild-type and drug-resistant form of the Smoothened receptor. Notably, these compounds repressed the Hh-dependent growth events and the proliferation of tumor cells with aberrant activation
通过钯催化的N-(2-碘芳基)烯胺酮的羰基环化反应制备的2-取代的3-aroylquinolin-4(1 H)-ones被证明可通过与野生型和药物的直接拮抗来有效抑制Hedgehog途径受体的抗性形式。值得注意的是,这些化合物通过异常激活Hh途径抑制Hh依赖性生长事件和肿瘤细胞的增殖,这在发育和肿瘤发生中起着至关重要的作用。
