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.

P1209New

TLQP-21 TFA

LQP-21 TFA (TLQP-21 Trifluoroacetate) is a VGF-derived peptide that activates the C3aR1 receptor through a folding-upon-binding mechanism.

E1048New

JR14a

JR14a, a selective and potent human Complement C3a receptor antagonist, which is assessed by inhibition of intracellular calcium release (IC50=10 nM) induced in human monocyte-derived macrophages by C3a, inhibition of β-hexosaminidase secretion (IC50=8 nM) from human LAD2 mast cells degranulated by C3a, and selectivity for human C3aR over C5aR.

S8931

SB290157 trifluoroacetate

SB290157 trifluoroacetate (SB 290157 TFA) is a potent, competitive and selective antagonist of C3a receptor (C3aR) with IC50 of 200 nM for RBL-C3aR.

S0525

ADH-503 (GB1275)

ADH-503 (GB1275, (Z)-Leukadherin-1 choline) is the salt form of leukadherin-1 and acts as a potent allosteric agonist of CD11b.

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)).
