pd 1 in 20

PD-1-IN-20 [476690-36-9] is the less active enantiomer of PD-1-IN-1 [1346528-06-1].

PD-1 PD-L1-IN-20 is a small molecule inhibitor of PD-1 PD-L1 protein-protein interaction, blocking the interaction with an IC50 of 5.29 nM. PD-1 PD-L1-IN-20 can be used to study cancer, infectious diseases, and autoimmune diseases.

Pixatimod (also known as PG-545) is a synthetic carbohydrate-modified heparan sulfate mimetic and a Toll-like receptor 9 (TLR9) agonist. It exhibits potential immunostimulatory, antitumor, and antiviral effects. Pixatimod effectively inhibits SARS-CoV-2 by disrupting the spike protein-ACE2 interaction. Additionally, it blocks various cancer-promoting processes such as cell proliferation, invasion, metastasis, angiogenesis, and epithelial-mesenchymal transition. These effects have demonstrated significant efficacy in numerous mouse cancer models, including about 30 xenograft models and 20 syngeneic models. Pixatimod has been tested in combination with several approved anticancer compounds, showing clinical potential when used with gemcitabine, paclitaxel, sorafenib, platinum compounds, and anti-PD-1 antibodies.

TPP-1, a peptide inhibitor, targets the interaction between programmed cell death protein 1 (PD-1) and its ligand (PD-L1), binding specifically to PD-L1 with a dissociation constant (Kd) of 94.67 nM. At a concentration of 20 µM, TPP-1 effectively counteracts the PD-L1-induced suppression of IFN-γ production in anti-CD3-stimulated isolated human CD4+ T cells. Furthermore, TPP-1 demonstrates significant efficacy in reducing tumor volume in a mouse xenograft model of HL-60 leukemia. This model involved HL-60 cells co-cultured with anti-CD3-activated isolated human CD4+ T cells, with TPP-1 administration at a dosage of 4 mg/kg showing notable antitumor activity.

H-20 is a PD-1 agonist that reduces the required dosage of morphine for analgesia. It can be used in studies related to chronic pain.
