Cyclosporin A is a natural product and an active fungal metabolite, classified as a cyclic polypeptide immunosuppressant. It binds to cyclophilin and inhibits the activity of calcineurin (IC₅₀ = 7 nM) as well as CD11a/CD18 adhesion molecules. It is commonly used to induce uremia models.

Dexamethasone is a glucocorticoid receptor agonist and IL receptor modulator with anti-inflammatory, immunosuppressive, and apoptosis-inducing activities. It inhibits the production of inflammatory miRNA-155 exosomes in macrophages, significantly reduces inflammatory cytokine expression in neutrophils and monocytes, suppresses LPS-induced macrophage inflammation, and induces autophagy. It is commonly used to induce animal models of depression, muscle atrophy, and hypertension, and holds potential in COVID-19 research.

Dextran sulfate sodium salt (MW 4500-5500) is a polymer of dehydrated glucose and an inhibitor of complement and coagulation pathways. Dextran sulfate sodium salt (MW 4500-5500) can be used as an anticoagulant, antiviral agent and antilipidemic agent. Dextran sulfate sodium salt (MW 4500-5500) can prevent the HIV-1 virus from adsorbing onto host cells. Dextran sulfate sodium salt (MW 4500-5500) can inhibit NK cell-mediated cytotoxicity. Dextran sulfate sodium salt (MW 4500-5500) can inhibit the immediate blood-mediated inflammatory response (IBMIR).
