STING agonist 1a is an agonist of stimulator of interferon genes (STING).1It induces expression of an IRF-inducible SEAP reporter gene in a cell-based assay (EC50= 16.77 μM). STING agonist 1a (12.5-100 μM) induces expression of IFN-β, IL-6, and chemokine (C-X-C motif) ligand 10 (CXCL10) in THP-1 cells, an effect that can be reversed by STING knockout or the STING inhibitor H-151 . 1.Hou, H., Yang, R., Liu, X., et al.Discovery of triazoloquinoxaline as novel STING agonists via structure-based virtual screeningBioorg.

STING agonist 12b is an agonist of stimulator of interferon genes (STING).1It binds to STING (Kd= 26.4 μM) and induces interferon reporter gene expression in cells expressing human or mouse STING (EC50s = 7.45 and 10.23 μM, respectively). STING agonist 12b (40 μM) induces expression of TNF-a, IL-6, IP-10, and IL-1b in THP-1 cells. 1.Hou, S., Lan, X.-j., Li, W., et al.Design, synthesis and biological evaluation of acridone analogues as novel STING receptor agonistsBioorg.

PD-1 PD-L1-IN 6 (compound A13) 是有效的PD-1 PD-L1相互作用抑制剂（IC50为 132.8 nM）。PD-1 PD-L1-IN 6 显示出显著的免疫调节活性。 在 Hep3B OS-8 hPD-L1 与 CD3 T 细胞共培养模型中，PD-1 PD-L1-IN 6显著提高干扰素 -γ 分泌，且无明显毒性作用。 在 T 细胞-肿瘤共培养模型中，PD-1 PD-L1-IN 6恢复免疫应答。

Ezabenlimab (BI-754091) 是一种抗PD-1单克隆抗体，结合PD-1的 Kd 为 6 nM (CHO 细胞)。Ezabenlimab 能够阻断PD-1与PD-L1和PD-L2的相互作用。Ezabenlimab 还增加 T 细胞内的 γ 干扰素分泌，抑制体内肿瘤生长。

STING激动剂D61（D61）是干扰素基因刺激剂(STING)的激动剂。它在基于细胞的分析中诱导IFN3诱导的分泌性碱性磷酸酶(SEAP)报告基因和IFN-β诱导的报告基因的表达（EC50分别为52.9和116 nM）。D61（4, 6, 和8 µM）增加了编码IFN-β和化学因子（C-X-C基序）配体10（CXCL10）的mRNA的表达以及TANK结合激酶1（TBK1）、IRF3和STING在THP-1单核细胞中的磷酸化。在体内，D61（每隔一天0.25 mg/kg）在CT26小鼠结肠癌模型中减少肿瘤体积，而不影响体重。

STING agonist C11 is an agonist of the stimulator of interferon genes (STING) pathway.1 It induces secretion of type I IFN from THF and MM6 cells when used at a concentration of 50 μM. STING agonist C11 induces phosphorylation of IFN regulatory factor 3 (IRF3) and increases expression of IFIT1 and viperin, but not IL-1β, IL-6, or IL-8 in THF cells in a STING-dependent manner. It reduces viral titers of chikungunya, Venezuelan equine encephalitis, o'nyong-nyong, Mayaro, and Ross River viruses grown in THF cells (EC90s = 16.44, 16.7, 18.84, 25.19, and 22.57 μM, respectively), an effect that is dependent on the presence of STING and the IFN-α β receptor (IFNAR).References1.

MRT67307 is an inhibitor for TBK1, IKKε , MARK1-4 and NUAK1 with IC50 value of 19, 160, 27-52 and 230nM , respectively [1]. It is an inhibitor for ULK1and ULK2 with IC50 value of 45 and 38nM, respectively [2]. Also, it is a salt inducible kinase (SIK) inhibitor with IC50 value of 250, 67 and 430nM for SIK1, SIK2 and SIK3, respectively.
SIKs prevent the formation of regulatory macrophages and their inhibition induces increasing in some markers of regulatory macrophages, such as IL-10 and other anti-inflammatory molecules. IKKε and TBK-1 mediate the phosphorylation of interferon regulatory factor 3 (IRF3). MARK1 is a Serine threonine-protein kinase.
In macrophages, MRT67307 prevented the production of IFNβ and the phosphorylation of IRF3 without suppressing the activation of NF-κB, which showed that MRT67307 blocked the induction of Pellino 1 through inhibiting TBK1 IKKε kinase activity [1] [3]. Also, MRT67307 completely blocked the TBK1- or IKKε-induced decrease in the mobility of Pellino 1 [3]. Exposed macrophages to MRT67307 increased the levels of the anti-inflammatory cytokines IL-1ra and IL-10 and decreased the levels of proinflammatory cytokines (such as IL-6, IL-12, and TNF) in response to bacterial lipopolysaccharide (LPS) [4].
