AI Technical Summary
Current STING inhibitors, such as H-151 and SN-011, are metabolically unstable, have poor water solubility, and lack selectivity, posing challenges in treating autoimmune and autoinflammatory diseases associated with abnormal STING activation.
Development of novel compounds, such as those of formula I, I-a, and I-b, or their salts, which act as potent and selective STING inhibitors, modulating STING pathway activity to reduce activation and associated cytokine release.
The compounds provide high potency and low toxicity, effectively inhibiting STING activation, reducing TBK1 activity, and alleviating conditions like systemic lupus erythematosus, Crohn's disease, and various inflammatory and autoimmune disorders.
