lipophilic ligand efficiency as a key metric to track changes in the physicochemical properties of our analogs, which led to improvements in overall compound quality. In parallel, structural information guided advancements in JAK1 selectivity by informing on new vector space, which enabled the discovery of a unique key amino acid difference between JAK1 (Glu966) and JAK2 (Asp939). This difference was
描述了一种适用于临床评估的有效的选择性低剂量Janus激酶1(JAK1)抑制剂的发现。作为将剂量降至最低的总体目标的一部分,我们奉行了一种药物化学策略,其重点是优化影响剂量大小(包括降低人体内C1代谢)的关键参数。并提高内在效力,生物利用度和溶解度。为了同时影响这些多个参数,我们使用亲脂性配体效率作为跟踪类似物理化性质变化的关键指标,从而改善了整体化合物的质量。同时,结构信息通过通知新的载体空间来指导JAK1选择性的发展,从而发现了JAK1(Glu966)和JAK2(Asp939)之间唯一的关键氨基酸差异。利用这种差异来始终如一地生产出具有JAK1选择性,功效和预计的人剂量最佳平衡的类似物,最终导致化合物28的发现。
