Description

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].

IC50 & Target

IRAK4

20 nM (IC50)

IRAK-1

24 nM (IC50)

CLK4

662 nM (IC50)

In Vitro

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].

Cell Viability Assay[1]

Cell Line: SK-OV-3, AN3-CA, H460, ES-2, SK-UT-1B, COLO205, Bx-PC-3
Concentration: 1 nM, 10 nM, 100 nM, 1 μM, 10 μM, and 10 μM+IL-1β (30 ng/ml)
Incubation Time: 24 h
Result: Inhibited cell survival by 21% for AN3-CA (pancreatic), and 13% for SKOV-3 (ovarian). The addition of IL-1β in conjunction with HS-243 increased cell death to 46% in SK-OV-3 (ovarian), 33% in AN3-CA (pancreatic), and 31% in H460 (colon).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
