体内活性

方法:为研究对肥胖相关炎症和代谢疾病的作用,将 2',3'-cGAMP sodium (0.2 mg/kg) 腹腔注射给高脂肪饮食 (HFD) 或低脂肪饮食 (LFD) 的 C57BL/6?J 小鼠,每天一次,持续四周。 结果:在肥胖小鼠中, 2',3'-cGAMP 治疗显著降低了饮食诱导的肝脏和脂肪组织的促炎反应,并改善了代谢失调。 2',3'-cGAMP 对巨噬细胞、肝细胞和脂肪细胞发挥细胞类型特异性抗炎作用。[1]

体外活性

在肿瘤细胞接种后7天,小鼠分别用zebularine、 2',3'-cGAMP sodium和 两者的联合治疗(为期10天)。将最终浓度为2.5 mg/mL的zebularine加入饮用水中,直至收集小鼠进行后续实验。每次在肿瘤旁注射含有10μg 2',3'-cGAMP sodium的100 μL PBS。2',3'-cGAMP sodium治疗每隔4天重复一次,共进行三次。本研究揭示了zebularine在增强cGAS-STING途径,促进抗肿瘤免疫反应中的作用。[4]

溶解度

DMSO:0.9 mg/mL (1.25 mM);H2O:45.0 mg/mL (62.6 mM)
