maintain their rapid growth and proliferation. Glutaminase 1 (GLS1) has been viewed as a promising target in the glutamine metabolism pathway for the treatment of malignant tumors. Using structure-based drug design approaches, a novel series of GLS1 allosteric inhibitors were designed and synthesized. Compound 41a (LWG-301) with an alkane chain “tail” group had potent biochemical and cellular GLS1 activity
肿瘤细胞通常表现出代谢重编程以维持其快速生长和增殖。谷氨酰胺酶 1 (GLS1) 已被视为谷氨酰胺代谢途径中用于治疗恶性肿瘤的有前途的靶标。使用基于结构的药物设计方法,设计并合成了一系列新的 GLS1 变构抑制剂。具有烷烃链“尾”基团的化合物41a ( LWG-301 ) 具有强大的生化和细胞 GLS1 活性,并改善了代谢稳定性。LWG-301在 HCT116 异种移植模型中表现出中等抗肿瘤作用,体内TGI 为 38.9% 。机械上,LWG-301可显着阻断谷氨酰胺代谢,导致细胞内相应氨基酸水平发生变化,诱导细胞内ROS水平呈浓度依赖性升高,并诱导细胞凋亡。综上所述,本文为GLS1变构抑制剂的开发提供了更多的结构参考和新的设计策略。
