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′-fluoro substituted, bis-3′,5′CDNs, and most preferably one or more 2′,2″-diF-Rp,Rp, bis-3′,5′CDNs.
本发明提供了高活性环状二核苷酸(CDN)免疫刺激剂,它能通过最近发现的一种称为 STING(干扰素
基因刺激器)的细胞质受体激活直流细胞、本发明的 CDN 以包含一种或多种环状
嘌呤二核苷酸的组合物的形式提供,该组合物能诱导人类 STING 依赖性 I 型干扰素的产生、其中组合物中的环
嘌呤二核苷酸是2′-
氟取代的双-3′,5′CDN,最优选的是一种或多种2′,2″-diF-Rp,Rp,双-3′,5′CDN。
