ADH-503 (GB1275) is an orally available, allosteric CD11b small molecule agonist that can lead to repolarization of tumor-associated macrophages, reduction in the number of tumor-infiltrating immunosuppressive myeloid cells, and enhancement of dendritic cell responses.

BCX 1470 hydrochloride is a potent serine protease inhibitor with anti-inflammatory activity that inhibits the ester hydrolysis and haemolytic activity of factor D and C1s, and can be used to study oedema.

EG01377 2HCl is a potent, bioavailable and selective inhibitor of neuropilin-1 (NRP1) with a Kd value of 1.32 μM and an IC50 value of 609 nM for both EG01377 2HCl against NRP1-a1 and NRP1-b1.EG01377 exhibits anti-angiogenic, antimigratory and antitumor activities.

Complement C5-IN-1 is a small-molecule inhibitor of complement component 5 protein (C5).

SB290157 trifluoroacetate is a potent and selective antagonist of the C3a receptor, with an IC50 of 200 nM.

CP-447697, a lipophilic C5a receptor antagonist, exhibits an IC50 of 31 nM. It is utilized in inflammation research.

Complement factor D-IN-2 is an inhibitor that reduces the excessive activation of Complement factor D.

C3a Receptor Agonist (C3a receptor agonist 1) binds the G protein-coupled C3a receptors (C3aRs) in the immune system complement pathway. Activation of C3aR prevents neutrophils from being mobilized in a model of intestinal ischemia-reperfusion injury. C3aRs are expressed on neural progenitor cells and immature neurons in adult mice. C3a stimulates differentiation of neural progenitor cells in vitro.
