IFNAR Activator

Ternatumoside II is a flavonoid glycoside that can be isolated from R. crenulata. Ternatumoside II can stimulate IFN-γ expression. Ternatumoside II has radical-scavenging activities (IC₅₀s: 260.5 μM and 320.2 μM for DPPH and ABTS).

Cridanimod is a potent progesterone receptor (PR) activator mediated through induction of IFNα and IFNβ expression. Cridanimod is a small-molecule immunomodulator and interferon inducer.

HPK1-IN-43 (compound 9f) is a HPK1 kinase inhibitor with the IC₅₀ value of 0.32 nM. HPK1-IN-43 inhibits the phosphorylation of the downstream protein SLP-76 and enhances the secretion of interleukin-2 (IL-2) and interferon-γ (IFN-γ). HPK1-IN-43 can be used in cancer research.

Antitumor agent-210 (Compound 1778) is an NK cell activator. Antitumor agent-210 has a weak proliferative effect on NK92 cells, promoting the activation and degranulation of NK cells, and significantly enhancing the cytotoxicity of NK92 cells against tumor cells. Antitumor agent-210 promotes the release of cytokine granzyme B, perforin, and IFN-γ. Antitumor agent-210 reduces the number of lung metastatic lesions in mice and can be used for the study of melanoma lung metastasis.
