2',3'cgamp

2',3'-cGAMP (2'-3'-cyclic GMP-AMP) 是细胞天然免疫中第二信使，在DNA结合条件下由 cGAMP 合成酶 (cGAS) 催化形成。2',3'-cGAMP 可与 STING 结合形成二聚体，诱导干扰素-β（IFN-β）及其他细胞因子的产生和表达。

2', 3'-cGAMP-C2-SH is a ADC cytotoxin.

2',3'-cGAMP-C2-PPA (45) is a cyclic di-nucleotide that acts as a STING agonist (US20210015941A1). It is a drug-linker conjugate for antibody-drug conjugates (ADC) used in the targeted treatment of cancer.

2',3'-cGAMP sodium (2'-3'-cyclic GMP-AMP sodium) 是细胞天然免疫中第二信使，在 DNA 结合条件下由 cGAMP 合成酶 (cGAS) 催化形成。2',3'-cGAMP sodium 可与 STING 结合形成二聚体，诱导 IFN-β 及其他细胞因子的产生和表达。

cAIMP作为STING激动剂，在体外的哺乳动物细胞中，与标准的小鼠（DMXAA）和人类（2',3'-cGAMP）STING激动剂相比，cAIMP类似物能更强烈地激活STING依赖的IRF和NF-κB信号通路。在人类血液的离体实验中，它们能诱导I型干扰素（IFNs）和促炎细胞因子的产生。

93-O17O is a chalcogen-containing cationic lipidoid.1,2It has been used in the generation of lipid nanoparticles (LPNs). LPNs containing 93-O17O localize to the spleen after intravenous injection into mice.1LPNs containing 93-O17O have been used for the delivery of Cre recombinase and ribonucleoproteins for genome editing in mice and for the intratumoral delivery of cGAMP to enhance cross-presentation of tumor antigens.3,2 1.Zhao, X., Chen, J., Qiu, M., et al.Imidazole-based synthetic lipidoids for in vivo mrna delivery into primary T lymphocytesAngew Chem.
