3-Hydroxykynurenamine, also known as 3-Hydroxy-L-kynurenamine or 3-HKA, is a biogenic amine produced via an alternative pathway of tryptophan metabolism. In vitro, 3-HKA has an anti-inflammatory profile by inhibiting the IFN-γ mediated STAT1/NF-κΒ pathway in both mouse and human dendritic cells (DCs) with a consequent decrease in the release of pro-inflammatory chemokines and cytokines, most notably TNF, IL-6, and IL12p70. 3-HKA has protective effects in an experimental mouse model of psoriasis by decreasing skin thickness, erythema, scaling and fissuring, reducing TNF, IL-1β, IFN-γ, and IL-17 production, and inhibiting generation of effector CD8+ T cells. Similarly, in a mouse model of nephrotoxic nephritis, besides reducing inflammatory cytokines, 3-HKA improves proteinuria and serum urea nitrogen, overall ameliorating immune-mediated glomerulonephritis and renal dysfunction.This compound is unstable in powder form and other related salt forms are recommended.
A-9758 is a RORγ ligand and a selective RORγt inverse agonist (IC50: 5 nM) and exhibits robust potency against IL-17A release. It is effective in suppressing both Th17 differentiation and Th17 effector function. A-9758 significantly attenuates IL-23 drive
AS2863619 free base enables the conversion of antigen-specific effector/memory T cells into Foxp3+ regulatory T (Treg) cells. It is a potent, orally active CDK8 and CDK19 inhibitor (IC50s: 0.61 nM and 4.28 nM). STAT5 activation enhanced by AS2863619 free base inhibition of CDK8/19, which consequently activates the Foxp3 gene.
PRN694 shows extended target residence time on ITK and RLK, enabling durable attenuation of effector cells in vitro and in vivo. PRN694 is an irreversible, highly selective, and effective covalent interleukin-2-inducible T-cell kinase (ITK) and resting ly
