Biochem/physiol Actions

PF-06282999 is an orally active thiouracil class myeloperoxidase (MPO) suicide substrate (kinact/KI = 11600 M-1s-1) that targets MPO heme group for mechanism-based irreversible inactivation wtih high selectivity over thyroid peroxidase (TPO kinact/KI <3 M-1s-1) and heme-containing cytochrome P450 (CYP) isoforms (IC50 >100 μM). PF-06282999 effectively inhibits MPO activity in human blood stimulated by LPS ex vivo (IC50 = 1.9 μM) and in blood of LPS-treated cynomolgus monkeys in vivo (5-80 mg/kg p.o. 1hr post LPS i.v.) with good pharmacokinetics and oral availability (100%/86%/75%/76% in mice/rats/dogs/monkeys). PF-06282999 also exhibits weak PXR activating activity (EC50/Emax = 279 μM/9.36-fold vs.0.8 μM/19.6-fold with rifampin).

Myeloperoxidase (MPO) is a heme peroxidase that catalyzes the production of hypochlorous acid. Clinical evidence suggests a causal role for MPO in various autoimmune and inflammatory disorders including vasculitis and cardiovascular and Parkinson's diseases, implying that MPO inhibitors may represent

Tumor necrosis commonly exists and predicts poor prognoses in many cancers. Although it is thought to result from chronic ischemia, the underlying nature and mechanisms driving the involved cell death remain obscure. Here, we show that necrosis in glioblastoma (GBM)
