Discovery of novel and potent lead molecules for the specific therapeutic targets by de novo drug design is still in infancy. Here, we disclose the unprecedented development of imidazopyri(mi)dine-based tumor pyruvate kinase M2 (PKM2) modulators by subsequent link and grow strategy. The most potent modulator 15n acts as a PKM2 activator with an AC50 of 90 nM, with considerable cancer cell-selectivity
通过从头 药物设计发现针对特定治疗靶点的新型有效先导分子仍处于起步阶段。 在这里,我们通过后续的链接和增长策略披露了基于咪唑并嘧啶 (mi)dine 的肿瘤丙酮酸激酶 M2 (PKM2) 调节剂的前所未有的发展。最有效的调节剂 15n 作为 PKM2 激活剂,AC 50 为 90 nM,具有相当大的癌细胞选择性和膜渗透性。NMR 代谢组学研究还表明,用15n处理会降低 MCF-7 细胞中的乳酸浓度。15n 与两个单体界面相邻的 PKM2 上先前报道的位点结合。在分子动力学 (MD) 模拟研究中,观察到15n在二聚体界面稳定 PKM2,有助于形成具有生物活性的四聚体构象。 还在 3-D 支架上生长的 MCF-7 乳腺癌细胞系上筛选了15n ,与对照相比,结果显示出更好的抗癌潜力,为未来的临床研究铺平了道路。
