Dexamethasone (MK-125)

Dexamethasone (MK-125, NSC 34521, Hexadecadrol, Prednisolone F) is a potent synthetic member of the glucocorticoid class of steroid drugs, and an interleukin receptor modulator that has anti-inflammatory and immunosuppressant effects. Dexamethasone induces autophagy and mitophagy. Dexamethasone is tested in hospitalized patients with COVID-19 and is found to have benefits for critically ill patients.

S2286

Cyclosporin A (NSC 290193)

Cyclosporin A (Cyclosporine A, Cyclosporine, Ciclosporin, CsA) is an immunosuppressive agent, binds to the cyclophilin and then inhibits calcineurin with IC50 of 7 nM in a cell-free assay, widely used in organ transplantation to prevent rejection.

S4028

Dexamethasone Sodium Phosphate

Dexamethasone (Dexamethasone 21-phosphate disodium salt) is a potent synthetic member of the glucocorticoid class of steroid drugs, and an interleukin receptor modulator that has anti-inflammatory and immunosuppressant effects.

S3124

Dexamethasone Acetate

Dexamethasone (NSC 39471) is a potent synthetic member of the glucocorticoid class of steroid drugs, and an interleukin receptor modulator that has anti-inflammatory and immunosuppressant effects.

S3240New

Phaseoloidin

Phaseoloidin, a homogentisic acid glucoside from Nicotiana attenuata trichomes, contributes to the plant's resistance against lepidopteran herbivores. Phaseoloidin has anti-complement effects.

S0803

Danicopan (ACH-4471)

Danicopan (ACH-4471, ACH-0144471, ACH-CFDIS, ALXN 2040) is a potent, selective and orally active inhibitor of factor D with Kd of 0.54 nM for human Factor D. Danicopan inhibits alternative pathway of complement (APC) activity, and has potential to block the alternative pathway of complement in paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS).

S8522

Compstatin

Compstatin binds to complement component C3 and inhibits complement activation with IC50 of 12 μM.

S9138

Picfeltarraenin IA

Picfeltarraenin IA is an AChE inhibitior, and an potential PI3K and EGFR inhibitor. It also acts as an inhibitor on both the classical and alternative pathways of the complement system.

S3612

Rosmarinic acid

Rosmarinic acid (RA, Rosemary acid) is a naturally occurring hydroxylated compound. It has the ability to block complement fixation, inhibit lipoxygenase and cyclooxygenase activity and inhibit the expression of CCL11 and CCR3 by suppressing the IKK-β activity in NF-κB activation signaling.

S8931

SB290157 trifluoroacetate

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

S0525

ADH-503

ADH-503 ((Z)-Leukadherin-1 choline) is an orally active and allosteric agonist of CD11b. ADH-503 leads to the repolarization of tumor-associated macrophages, reduction in the number of tumor-infiltrating immunosuppressive myeloid cells, and enhances dendritic cell responses.

S8306

Leukadherin-1

Leukadherin-1 (LA1) is a small molecule agonist that enhances CD11b/CD18-dependent cell adhesion to its ligand ICAM-1(an agonist for the complement receptor 3 (CD11b/CD18)).
