The present invention provides highly active cyclic-di-nucleotide (CDN) immune stimulators that activate DCs via a recently discovered cytoplasmic receptor known as STING (Stimulator of Interferon Genes). In particular, the CDNs of the present invention are provided in the form of a composition comprising one or more cyclic purine dinucleotides induce human STING-dependent type I interferon production, wherein the cyclic purine dinucleotides present in the composition are 2′- or 3′-mono-fluoro substituted, or 2′3′-di-fluoro substituted mixed linkage 2′,5′-3′,5′ CDNs.
本发明提供了高活性环状二核苷酸(CDN)免疫刺激剂,可通过最近发现的一种称为 STING(干扰素基因刺激器)的细胞质受体激活 DC。特别是,本发明的 CDN 以组合物的形式提供,该组合物包含一种或多种环状嘌呤二核苷酸,可诱导人类 STING 依赖性 I 型干扰素的产生、其中组合物中的环状嘌呤二核苷酸是2′-或3′-单氟取代的,或2′3′-二氟取代的混合连接2′,5′-3′,5′CDN。
