General description

A cell-permeable symmetrical sulfone compound that acts as a potent and ATP-competitive inhibitor of p38α/β MAPK (IC50 = 130 and 550 nM, respectively), while exihibiting much reduced activity (≤23% inhibition at 1 µM) against p38γ/δ, ERK1/2, and JNK1/2/3. Shown to be more effective than SB 203850 (Cat. Nos. 559389, 559395, and 559398) in inhibiting LPS-induced IL-1β release from hPBMC (100% vs. 50% inhibition with 100 µM respective inhibitor).

Histamine receptor 1 (HRH1) belongs to the rhodopsin-like G-protein-coupled receptor family. Its activation by histamine triggers cell proliferation, embryonic development, and tumor growth. We recently established that HRH1 is up-regulated in basal and human epidermal growth factor receptor 2 (HER2)-enriched
