BRAF is a serine/threonine kinase that is mutated in a range of cancers, including 50−70% of melanomas, and has been validated as a therapeutic target. We have designed and synthesized mutant BRAF inhibitors containing pyridoimidazolone as a new hinge-binding scaffold. Compounds have been obtained which have low nanomolar potency for mutant BRAF (12 nM for compound 5i) and low micromolar cellular potency
BRAF是一种丝氨酸/苏氨酸激酶,在多种癌症(包括50%至70%的黑色素瘤)中都会发生突变,并且已被证实可作为治疗靶标。我们已经设计并合成了含有吡啶并咪唑酮作为新型铰链结合支架的BRAF突变体抑制剂。已经获得对突变BRAF具有低纳摩尔效能(对于化合物5i为12nM )和对突变BRAF黑色素瘤细胞系WM266.4具有低微摩尔细胞效能的化合物。该系列得益于极低的新陈代谢,以及可以通过咪唑酮的NH基团的甲基化来调节的药代动力学(PK),从而使化合物具有更少的H-供体和更好的PK谱。这些化合物在治疗突变型BRAF黑色素瘤中具有巨大潜力。
