Dexamethasone-4,6α,21,21-d4 is the deuterium labeled Dexamethasone-4,6α,21,21. Dexamethasone (Hexadecadrol) is a glucocorticoid receptor agonist. Dexamethasone also significantly decreases CD11b, CD18, and CD62L expression on neutrophils, and CD11b and CD18 expression on monocytes. Dexamethasone is highly effective in the control of COVID-19 infection. Dexamethasone inhibits production of exosomes containing inflammatory microRNA-155 in lipopolysaccharide-induced macrophage inflammatory responses.
Olendalizumab (ALXN1007) is a mouse-derived and humanized IgG2-G4-κ antibody, targeting to Complement protein C5a (Ki=60 pM). Olendalizumab targets the complement inflammatory pathway. Moreover, Olendalizumab can be used for research of complement mediated disorder caused by corona virus[1][2].
Certepetide (CEND-1) is a bifunctional cyclic peptide (a.k.a. iRGD). Certepetide is a tumor-penetrating enhancer via RGD motif interaction with alphav-integrins and via activating NRP-1, and transforms the solid tumor microenvironment into a temporary drug conduit. Certepetide accumulates in tumors, and is used in the research of pancreatic cancer and other solid tumors[1][2][3].
Factor B-IN-4 (Example 13 target compound) is a potent complement factor B inhibitor, with an IC50 of 1 μM. Factor B-IN-4 can be used for the research of diseases related to inflammation and immunity[1].
Leukadherin-1 is a specific agonist of CR3 and the leukocyte surface integrin CD11b/CD18.
Factor D inhibitor 6 is a potent and selective, orally bioavailable inhibitor of Factor D with IC50 of 30 nM; is highly selective for human FD, showing no inhibition of factor B; efficiently block alternative pathway activation and prevent both C3 deposition onto, and lysis of, PNH erythrocytes; inhibits lipopolysaccharide-induced AP activation in FD-humanized mice.
C5a Receptor agonist, mouse, human is a biological active peptide. (This peptide is derived from the C-terminus of the chemokine, complement fragment 5 anaphylatoxin (C5a). This peptide functions as a C5a receptor agonist. C5a is a plasma protein involved in cellular inflammatory processes by inducing chemotaxis, degranulation of leukocytes, increased vascular permeability, and cytokine production. The cyclohexylalanine at position 5 is crucial to agonist function. Arg at the last position is of the d-isomer.)
TLQP-21, a VGF-derived peptide endowed of endocrine and extraendocrine properties, is a potent G-protein-coupled receptor complement-3a receptor 1 (C3aR1) agonist (EC50: mouse TLQP-21=10.3 μM; human TLQP-21=68.8 μM). TLQP-21 activates C3aR1 to induce an increase of intracellular Ca2+. TLQP-21 is used for the research in regulation of nociception and other relevant physiologic functions[1][2].
W-54011 is a potent, specific, and orally active CD88 (C5a receptor) antagonist. W-54011 inhibits the binding of 125I-labeled C5a to human neutrophils with a Ki value of 2.2 nM.IC50 value: 2.2 nM (Ki)Target: CD88 (C5a receptor)in vitro: W-54011 also inhibits C5a-induced intracellular Ca2+ mobilization, chemotaxis, and generation of reactive super oxide species in human neutrophils with IC50 alues of 3.1, 2.7, and 1.6 nM, respectively. In C5a-induced intracellular Ca2+ obilization assay with human neutrophils, W-54011 does not show agonistic activity at up to 10 μM and shifts rightward the concentration-response curves to C5a without depressing the maximal responses. in vivo: Examination on the species specificity of W-54011 reveals that it was able to inhibit C5a-induced intracellular Ca2+ mobilization in neutrophils of cynomolgus monkeys and gerbils but not mice, rats, guinea pigs, rabbits, and dogs. In gerbils, oral administration of W-54011 (3-30 mg/kg) inhibits C5a-induced neutropenia in a dose-dependent manner. The present report is the first description of an orally active non-peptide C5a receptor antagonist that could contribute to the treatment of inflammatory diseases mediated by C5a.
POT-4 (AL-78898A), a Compstatin derivative, is a potent inhibitor of complement factor C3 activation. POT-4 can be used for age-related macular degeneration research[1][2]
NRP1 antagonist 1 (compound 12a) is a potent NRP1 antagonist with an IC50 of 19.1 μM. NRP1 antagonist 1 has the potential for cancer research[1].
