azabenzimidazole (ABI) series of SYK inhibitors by mining activity data of 86,000 compounds from legacy biochemical assays with SYK and other homologous kinases as target enzymes. A structure-based design and hybridization approach was then used to improve the potency and kinase selectivity of the hits. Lead compound 23 from this novel ABI series has a SYK IC50 = 0.21 nM in a biochemical assay and inhibits growth
脾酪氨酸激酶(SYK)是一种经过广泛研究的酶,在肿瘤学和自身免疫性疾病中具有治疗应用。通过从传统生化分析中以SYK和其他同源激酶作为目标酶的86,000种化合物的活性数据的挖掘,我们确定了氮杂苯并咪唑(ABI)系列的SYK抑制剂。然后使用基于结构的设计和杂交方法来提高命中的效力和激酶选择性。来自该新型ABI系列的先导化合物23 在生化分析中的SYK IC 50 = 0.21 nM,并在GI 50 = 210 nM时抑制SUDHL-4细胞的生长。
