HS-243 is a potent and selective IRAK-4 and IRAK-1 inhibitor, with IC50 values of 20 and 24 nM. HS-243 shows minimal TAK1 (transforming growth factor β-activated kinase 1) inhibition activity, with a IC50 of 0.5 μM. HS-243 shows anti-inflammatory and anticancer activity[1].
HS-243 (0-10 μM, 24 h) inhibits cell survival by 21% for AN3-CA (pancreatic cancer cell), and 13% for SKOV-3 (ovarian cancer cell)[1].
HS-243 (10 μM, 24 h) potently reduces the proinflammatory response of RA cells and macrophages, significantly reduces the secretion of 15 cytokines, including IL-8, CD14, GRO-α, MIP-1a, MIP-3a, uPAR, Osteopontin, MMP-9, MCP-1, I-TAC, TIM-3, IP-10, GDF-15, and RANTES[1].
HS-243 shows minimal to no percentage of inhibition against IRAK-4 Y262T or Y262A mutants at 0.3 and 1 μM[1].

A highly selective inhibitor of interleukin-1 receptor-associated kinases 1/4 (IRAK-1/4) delineates the distinct signaling roles of IRAK-1/4 and the TAK1 kinase
J Biol Chem 2020 Feb 7;295(6):1565-1574.PMID:31914413DOI:PMC7008364
Interleukin-1 receptor-associated kinase-1 (IRAK-1) and IRAK-4, as well as transforming growth factor β-activated kinase 1 (TAK1), are protein kinases essential for transducing inflammatory signals from interleukin receptors. IRAK family proteins and TAK1 have high sequence identity within the ATP-binding pocket, limiting the development of highly selective IRAK-1/4 or TAK1 inhibitors. Beyond kinase activity, IRAKs and TAK1 act as molecular scaffolds along with other signaling proteins, complicating the interpretation of experiments involving knockin or knockout approaches. In contrast, pharmacological manipulation offers the promise of targeting catalysis-mediated signaling without grossly disrupting the cellular architecture. Recently, we reported the discovery of takinib, a potent and highly selective TAK1 inhibitor that has only marginal activity against IRAK-4. On the basis of the TAK1-takinib complex structure and the structure of IRAK-1/4, here we defined critical contact sites of the takinib scaffold within the nucleotide-binding sites of each respective kinase. Kinase activity testing of takinib analogs against IRAK-4 identified a highly potent IRAK-4 inhibitor (HS-243). In a kinome-wide screen of 468 protein kinases, HS-243 had 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 evaluated 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. Our results indicate that HS-243 specifically inhibits intracellular IRAKs without TAK1 inhibition and that these kinases have distinct, nonredundant signaling roles.
