central protein in the innate immune response to cytosolic DNA, has emerged as a hot target for the development of vaccine-adjuvants and anticancer drugs. The discovery of potent human-STING (hSTING) agonist is expected to revolutionize the current cancer immunotherapy. Inspired by the X-ray crystal structure of DMXAA (5,6-dimethylxanthenone-4-acetic acid) and hSTINGG230I complex, we designed various DMXAA
STING是先天性的对胞质DNA免疫反应的核心蛋白,已成为开发疫苗佐剂和抗癌药物的热门目标。强大的人类STING(hSTING)激动剂的发现有望彻底改变当前的癌症免疫疗法。受到DMXAA(5,6-二甲基黄嘌呤酮4-乙酸)和hSTING G230I的X射线晶体结构的启发我们设计了各种DMXAA衍生物,在C7位上含有氢键供体/受体或卤化物。虽然7-溴和7-羟基-DMXAA与小鼠STING(mSTING)表现出显着结合,但我们新合成的C7-官能化DMXAA衍生物未与hSTING结合。尽管如此,我们为DMXAA的C7功能化而新开发的合成方案仍可适用于访问其他C7取代的DMXAA类似物作为潜在的hSTING激动剂。
