生物活性

製品説明	HS-243 is a highly potent interleukin-1 receptor-associated kinase (IRAK) inhibitor with IC50 of 24 nM, 20 nM and 0.5 μM for IRAK-1, IRAK-4 and TAK1, respectively.
in vitro	HS-243 has exquisite selectivity toward both IRAK-1 (IC50 = 24 nM) and IRAK-4 (IC50 = 20 nM), with only minimal TAK1-inhibiting activity (IC50 = 0.5 μM). Using HS-243 and takinib, we evaluates the consequences of cytokine/chemokine responses after selective inhibition of IRAK-1/4 or TAK1 in response to lipopolysaccharide challenge in human rheumatoid arthritis fibroblast-like synoviocytes. HS-243 specifically inhibits intracellular IRAKs without TAK1 inhibition and these kinases have distinct, nonredundant signaling roles.^[1]

キナーゼアッセイ	Activity of purified IRAK-4 protein
キナーゼアッセイ	In brief, IRAK-4 (20 ng/well) is incubated with 2 mM ATP containing radiolabeled [32P]ATP in the presence of 300 μM substrate peptide in a final volume of 40 μl in the presence of buffer and HS-243. The reaction is terminated at 20 min with 10 μl of 1 M H3PO4. The remaining activity is measured using a scintillation counter. Dose–response curves are repeated two times and averaged.
細胞アッセイ	細胞株	RA-FLS cells, THP-1 cells
	濃度	10 μM
	反応時間	24 h
	実験の流れ	RA-FLS cells or THP-1 cells are treated with 10 μM HS-243 or vehicle (DMSO), and 24 h after treatment, supernatant is added to human cytokine XL proteome array in accordance with the manufacturer’s protocol. Chemiluminescence is used to visualize protein quantities.
