hypothesized to render immune infiltrates more effective at countering tumor growth. To test this hypothesis, a family of benzoxazines was optimized to provide LYC-55716 (37c), a potent, selective, and orally bioavailable small-molecule RORγ agonist. LYC-55716 decreases tumor growth and enhances survival in preclinical tumor models and was nominated as a clinical development candidate for evaluation in
视黄酸受体相关孤儿受体 γ(RORc、RORγ 或 NR1F3)是核受体主转录因子,可驱动产生 IL-17 的 T 辅助细胞 (Th17)、细胞毒性 T 细胞 (Tc17) 和细胞的功能和发育。先天淋巴细胞的亚群。假设肿瘤微环境中 RORγ + T 细胞的激活可以使免疫浸润更有效地对抗肿瘤生长。为了检验这一假设,对苯并嗪家族进行了优化,以提供 LYC-55716 ( 37c ),这是一种有效的、选择性的、口服
生物可利用的小分子 RORγ 激动剂。 LYC-55716 可减少临床前肿瘤模型中的肿瘤生长并提高生存率,并被提名为用于实体瘤患者评估的临床开发候选药物。
