Abstract

Introduction: SOS1 is a crucial guanine nucleotide exchange factor for KRAS. It facilitates the transition of KRAS from inactive GDP-bound state to active GTP-bound state. The activation of KRAS triggers downstream signaling pathways, promoting tumor initiation and progression. Inhibiting SOS1 to prevent KRAS activation is an effective strategy for treating tumors driven by KRAS.

Areas covered: This review identified patents claiming to be SOS1 inhibitors or SOS1-KRAS interaction modulators published between January 2022 and June 2024 using Cortellis Drug Discovery Intelligence. A total of 15 patent applications from 5 different applicants were assessed.

Expert opinions: In KRAS-driven tumors, inhibiting SOS1 significantly affect cell proliferation and migration by modulating the RAS/MAPK and PI3K/AKT/mTOR signaling pathways. Since 2022, numerous patents for SOS1 inhibitors have been published. The majority of SOS1 inhibitors are currently in the preclinical phase of development, with only a few progressing to clinical trials. However, these inhibitors face significant challenges in clinical studies, including limited efficacy of monotherapies, safety concerns, and the necessity to enhance PK properties. Despite their excellent in vitro performance, SOS1 inhibitors must address issues related to safety, pharmacokinetics, and pharmacodynamics in clinical applications.

SOS1 抑制剂最新专利回顾(2022 年至今)。
简介SOS1 是 KRAS 的一个重要鸟嘌呤核苷酸交换因子。它能促进 KRAS 从非活性 GDP 结合态转变为活性 GTP 结合态。KRAS 的激活会触发下游信号通路,促进肿瘤的发生和发展。抑制 SOS1 以防止 KRAS 激活是治疗由 KRAS 驱动的肿瘤的有效策略:本综述利用 Cortellis Drug Discovery Intelligence 查找了 2022 年 1 月至 2024 年 6 月间公布的声称是 SOS1 抑制剂或 SOS1-KRAS 相互作用调节剂的专利。共评估了来自5个不同申请人的15项专利申请:在KRAS驱动的肿瘤中,抑制SOS1可通过调节RAS/MAPK和PI3K/AKT/mTOR信号通路,显著影响细胞的增殖和迁移。自 2022 年以来,SOS1 抑制剂的多项专利已经公布。目前,大多数 SOS1 抑制剂都处于临床前开发阶段,只有少数进入了临床试验阶段。然而,这些抑制剂在临床研究中面临着巨大的挑战,包括单一疗法的有限疗效、安全性问题以及增强 PK 特性的必要性。尽管 SOS1 抑制剂在体外表现出色,但在临床应用中必须解决与安全性、药代动力学和药效学相关的问题。
