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 dinuclotides 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的环二核苷酸(CDN)免疫刺激剂,通过一种最近发现的细胞质受体STING(干扰素
基因刺激因子)激活DCs。具体而言,本发明的CDN以一种组合物的形式提供,其中包括一种或多种环
嘌呤二核苷酸,诱导人类STING依赖型I干扰素的产生,所述组合物中的环
嘌呤二核苷酸为2'-
氟取代的双3',5'CDNs,最好是一种或多种2',2"-二F-Rp,Rp,双3',5'CDNs。
