ifn-α

IFN-α Receptor Recognition Peptide 1, associated with receptor interactions, is a peptide of IFN-α.

IFN-γ Antagonist 1 (AYCRDGKIGPPKLDIRKEEKQI), an interferon γ (IFN γ) antagonist, effectively inhibits IFN-γ induced HLR/DR antigen expression in Colon 205 cells, demonstrating an IC50 of approximately 35 μM. This compound shows promise for applications in immune regulation [1].

IFN-γ Antagonist 1 (AYCRDGKIGPPKLDIRKEEKQI) acetate, an interferon γ (IFN γ) antagonist, effectively inhibits the expression of HLR/DR antigen in Colon 205 cells induced by IFN-γ, with an IC50 of approximately 35 μM. This compound holds promise for applications in immune regulation [1].

Delmitide acetate (RDP58) is an orally active d-isomer decapeptide with potent anti-inflammatory properties, suppressing TNF-α, IFN-γ, and interleukin (IL)-12 production, while enhancing heme oxygenase 1 activity. It is utilized in research related to ulcerative colitis [1] [2].

Delmitide, a TNF-alpha production inhibitor, is used potentially for the treatment of Crohn's disease and ulcerative colitis.

Defensin HNP-1, human acetate is an antimicrobial peptide and human α -defensin found mainly in neutrophils with broad-spectrum antimicrobial activity against bacteria and viruses, triggers NF-κB and IRF1 thereby increasing IFN-α, induces apoptosis in tumor cells, inhibits vascular endothelial cell function, mediates immunity to infections and more.

Interphotoreceptor retinoid-binding protein (651-670) (IRBP651-670), a peptide fragment of retinoid-binding protein 3 (also known as IRBP), plays a crucial role in the visual cycle by facilitating the transport of retinol and retinal between photoreceptor cells and the retinal pigment epithelium. This transport is essential for the regeneration of pigments necessary for vision. When administered at a dose of 300 µg/animal, IRBP651-670 induces autoimmune uveoretinitis in C57BL/6 mice, a model possessing the H-2b haplotype. This immunization leads to increased levels of ocular cytokines including IL-1β, IL-6, IL-17, TNF-α, and IFN-γ, promotes immune cell infiltration into the eye, and results in photoreceptor cell damage.

Eps8 peptide 327 is an HLA-A*2402-restricted peptide antigen derived from the Eps8 protein. It exhibits potent antitumor activity and significant cytotoxicity. Eps8 peptide 327 effectively inhibits cancer cell proliferation, induces apoptosis, and disrupts the EGFR signaling pathway by inhibiting the expression of downstream signals such as IL-2, TNF-α, and IFN-γ, as well as impeding the Eps8/EGFR interaction. It significantly suppresses tumor growth in HT-29 xenograft models.

TAT-327 is a cell-penetrating peptide known for selectively inserting into cancer cell membranes and exhibiting potent anti-tumor activity. It effectively inhibits cancer cell proliferation, induces apoptosis, and disrupts the EGFR signaling pathway by suppressing the expression of downstream signals (such as IL-2, TNF-α, and IFN-γ) and the interaction between Eps8 and EGFR. Additionally, TAT-327 significantly inhibits tumor growth in HT-29 xenograft models.
