Biochem/physiol Actions
PF-05480090 (PF-5480090; TMI-2) is an orally active, potent TACE (ADAM17) inhibitor (IC50 = 2 nM) with good selectivity over ADAM10 (IC50 = 1.09 μM), MMP-1/7 (IC50 = 2.47/0.96 μM) and MMP-8/9/13/14 (IC50 =35/ 777/96/582 nM). TMI-2 inhibits LPS-induced TNF production in cultrues (RAW/THP-1 IC50 = 200/430 nM), ex vivo (human whole blood IC50 = 1 μM) and in vivo (ED50 = 3 mg/kg; TMI-2 p.o. 1 hr prior to 40 ng LPS/mouse i.v.). TMI-2 is efficacious in a rat model of adjuvant-induced arthritis (AIA; 30 and 100 mg/kg p.o. b.i.d.) and a murine model of collagen-induced arthritis (CIA; 100 mg/kg p.o. b.i.d.).

The EGF receptor (EGFR)/a disintegrin and metalloproteinase 17 (ADAM17) signaling pathway mediates the shedding of growth factors and secretion of cytokines and is involved in chronic inflammation and tissue remodeling. Since these are hallmarks of cystic fibrosis (CF) lung disease

ADAM17 (a disintegrin and metalloproteinase-17) is a membrane-bound enzyme that regulates bioavailability of multiple transmembrane proteins by proteolytic processing. ADAM17 has been linked to several pathologies, but its role in thoracic aortic aneurysm (TAA) has not been determined. The objective

Myeloid-derived suppressor cells (MDSC) contribute to an immunosuppressive network that drives cancer escape by disabling T cell adaptive immunity. The prevailing view is that MDSC-mediated immunosuppression is restricted to tissues where MDSC co-mingle with T cells. Here we show that
