The present invention relates to a non-canonical cyclic di-nucleotide containing an asymmetric 2'-5' and 3'-5' phosphodiester linkage and its use in a method for identifying a substance having an ability to modulate cGAS activity or bind to STING. Furthermore, the cyclic dinucleotide is used in a method of identifying a substance having an ability to modulate the activity of a 2'-5' phosphodiesterase.
本发明涉及一种含有不对称 2'-5'和 3'-5'
磷酸二酯连接的非经典环状二核苷酸及其在鉴定具有调节 cGAS 活性或与 STING 结合能力的物质的方法中的用途。此外,环状二核苷酸还可用于鉴定具有调节 2'-5'
磷酸二酯酶活性的物质的方法。
