S-72是一种微管聚合抑制剂，以1, 3, 10 µM的浓度在无细胞测定中抑制微管聚合，并在MCF-7和耐紫杉醇的MCF-7/T乳腺癌细胞中降低细胞活性（IC50分别为15.64和26.32 nM）。50 nM浓度的S-72能抑制MCF-7和MCF-7/T细胞的迁移和侵袭，并减少划痕实验中的伤口闭合百分比。100 nM的S-72在MCF-7/T细胞中诱导G2/M期的细胞周期阻滞以及凋亡，并在同一浓度下抑制这些细胞中干扰素基因激活剂（STING）的激活。以每天15 mg/kg的剂量，S-72抑制了耐紫杉醇的MCF-7/T和MX-1/T小鼠异种移植模型中的肿瘤生长。

STING-IN-7（化合物 21），作为一种STING抑制剂，具有11.5 nM的IC50值，能够抑制STING与干扰素调节因子 3 (IRF3) 的磷酸化。

93-O17S is a chalcogen-containing cationic lipidoid.1It has been used in the synthesis of lipid nanoparticles (LPNs) for the delivery of Cre recombinase and ribonucleoproteins for genome editing in mice. LPNs containing 93-O17S have been used for the intratumoral delivery of cGAMP to enhance cross-presentation of tumor antigens and stimulation of interferon genes (STING) activation in a B16 F10 murine melanoma model.2 1.Li, Y., Yang, T., Yu, Y., et al.Combinatorial library of chalcogen-containing lipidoids for intracellular delivery of genome-editing proteinsBiomaterials178652-662(2018) 2.Chen, J., Qiu, M., Ye, Z., et al.In situ cancer vaccination using lipidoid nanoparticlesSci.

ANA773 is a Toll-like Receptor 7 (TLR7) agonist prodrug with potential immunostimulating activity. Upon oral administration, ANA773 is metabolized into its active form that binds to and activates TLR7, thereby stimulating dendritic cells (DCs) and enhancing natural killer cell (NK) cytotoxicity. This activation results in the production of proinflammatory cytokines, including interferon alpha, and enhanced antibody-dependent cellular cytotoxicity (ADCC). TLR7 is a member of the TLR family, which plays a fundamental role in pathogen recognition and activation of innate immunity.

GSK-2245035 maleate is a selective Toll-like receptor 7 (TLR7) agonist with preferential Type-1 interferon (IFN)-stimulating properties.
