  Son of sevenless homologue 1 (SOS1) is a guanine nucleotide exchange factor that catalyzes the exchange of GDP for GTP on RAS. In its active form, GTP-bound RAS is responsible for numerous critical cellular processes. Aberrant RAS activity is involved in ∼30% of all human cancers; hence, SOS1 is an attractive therapeutic target for its role in modulating RAS activation. Here, we describe a new series

  七分之一同源基因1（SOS1）的儿子是鸟嘌呤核苷酸交换因子，它催化RAS上的GTP交换GDP。GTP结合的RAS以其活跃的形式负责众多关键的细胞过程。约30％的人类癌症都涉及RAS异常活动。因此，SOS1因其在调节RAS激活中的作用而成为有吸引力的治疗靶标。在这里，我们描述了一系列新的苯并咪唑衍生的SOS1激动剂。使用结构指导的设计，我们发现了小分子，可在亚微摩尔浓度下增加RAS在体外的核苷酸交换，以低的两位数纳摩尔亲和力与SOS1结合，迅速增强细胞RAS-GTP水平，并在ERK磷酸化中引起双相信号变化。 1/2。这些化合物代表了迄今为止报道的最有效的SOS1激动剂系列。
