Protein kinase C iota (PKC-ι) is an atypical kinase implicated in the promotion of different cancer types. A biochemical screen of a fragment library has identified several hits from which an azaindole-based scaffold was chosen for optimization. Driven by a structure–activity relationship and supported by molecular modeling, a weakly bound fragment was systematically grown into a potent and selective inhibitor against PKC-ι.

蛋白质激酶C Iota抑制剂的基于片段的药物发现

蛋白激酶C iota（PKC-1）是一种非典型激酶，与促进不同类型的癌症有关。片段文库的生化筛选已鉴定出多个命中，从中选择了基于氮杂吲哚的支架进行优化。在结构-活性关系的驱动下，并在分子模型的支持下，弱结合的片段被系统地生长为有效且选择性的针对PKC-1的抑制剂。
