SHR-1806 is a OX40 agonist and a NF-κB activator, with antitumor activity. SHR-1806 mediates ADCC and CDC effects, enhances the function and expansion of effector T cells, suppresses regulatory T cells, and increases γ-interferon secretion. SHR-1806 exhibits typical pharmacokinetic characteristics and favorable safety profiles. SHR-1806 can be used in studies related to solid tumors and colon cancer.

Vonlerolizumab (Pogalizumab; MOXR 0916) is a humanized IgG1 monoclonal antibody targeting OX40 (CD134). Pogalizumab partially blocks the interaction between OX40 and its natural ligand OX40L upon binding, thereby activating the NF-κB signaling pathway. Pogalizumab enhances T cell activation and proliferation and has shown antitumor activity in mouse models.

Ordastobart (INBRX-106; ES-102) is a hexavalent OX40 agonist antibody. Ordastobart enhances OX40 receptor clustering, signaling, and downstream activation, thereby increasing the proliferation and activation of CD4⁺ and CD8⁺ T cells in vitro and in vivo. Ordastobart exhibits anti-tumor effects and improves survival in mouse models of cancer. Ordastobart is indicated for research in cancers such as fibrosarcoma and colorectal cancer.

Cleminorexton is an orally active orexin-2 receptor (OX2R) agonist with a pEC₅₀ between 9 and 10.4. Cleminorexton can be used for narcolepsy and other conditions associated with orexin deficiency and/or excessive sleepiness.

Anti-Mouse OX40/CD134 Antibody (OX-86) is an anti-mouse OX40/CD134 IgG1 monoclonal antibody. Anti-Mouse OX40/CD134 Antibody (OX-86) can enhance the anti-tumor function of CD8⁺ T cells. Anti-Mouse OX40/CD134 Antibody (OX-86) can reverse immune suppression, enhance antigen presentation and T cell activation. Anti-Mouse OX40/CD134 Antibody (OX-86) can be used for research on cancer such as papilloma and leukemia.

Efizonerimod alfa (MEDI-6383) is a recombinant human OX40L IgG4P Fc fusion protein that assembles into a hexameric structure and exerts potent agonist activity upon binding to OX40. The activity of Efizonerimod alfa is enhanced by Fcγ receptor-mediated aggregation. Efizonerimod alfa binds to OX40 on the surface of activated T cells, induces NF-κB promoter activity in OX40-expressing T cells, and triggers the production of Th1-type cytokines, T cell proliferation, and resistance to regulatory T cell (Treg)-mediated suppression. Efizonerimod alfa enhances the cytolytic activity of tumor-reactive T cells and slows tumor growth in immunodeficient mice. Efizonerimod alfa induces the proliferation of CD4, CD8, and B cells in the peripheral blood of healthy non-human primates. Efizonerimod alfa can be used in the research of advanced solid malignancies and melanoma.

(R,R)-Suntinorexton is a isomeride of Suntinorexton (HY-137452). Suntinorexton is a orexin type 2 receptor agonist.

(S)-YNT-3708, the S-enantiomer of YNT-3708, with low activity for OX1R and OX2R (EC₅₀ = 3595 nM and 1661 nm, respectively).

YNT-3708 is an orexin receptor (OXR) agonist, with EC₅₀ values of 14.6 nM and 277 nm for OX1R and OX2R, respectively.

Xenopus orexin B is a neuropeptides that identified as an endogenous ligands for an orphan G-protein-coupled receptor. Xenopus orexin B is a potent agonist of OX₂R.

Orexin B, human is an endogenous agonist at Orexin receptor with K_is of 420 and 36 nM for OX1 and OX2, respectively.

OX2R agonist 1 is an OX2R antagonist with an EC₅₀ of less than 100 nM. OX2R agonist 1 can be used in research related to excessive daytime sleepiness or narcolepsy.

Anti-Mouse OX40/CD134 (LALA-PG) Antibody (OX86) is an anti-mouse OX40/CD134 (LALA-PG) IgG2a monoclonal antibody. Anti-Mouse OX40/CD134 (LALA-PG) Antibody (OX86) is a chimeric antibody of the original OX86 antibody (HY-P990115). Anti-Mouse OX40/CD134 (LALA-PG) Antibody (OX86) can significantly enhance the generation of antigen-specific effector T cells. Anti-Mouse OX40/CD134 (LALA-PG) Antibody (OX86) can be used for research on cancer .
