    PDE4A1, IC50:0.7 nM
描述 Phosphodiesterases (PDEs) are a family of enzymes that catalyze the hydrolysis of cyclic adenosine monophosphate and cyclic guanosine monophosphate. Roflumilast is a potent inhibitor of both human PDE4B and PDE4D with IC50 values of 0.84 and 0.68nM, respectively, while it showed much less inhibitory activity against other forms of PDEs (IC50 values > 10μM)[7]. In A549 cells, roflumilast at the dose of 1μM prevented EGF-stimulated increase in MUC5AC mRNA and protein production but did not change the basal MUC5AC expression, and also inhibited EGF-induced phosphorylation of tyrosine residues of different intracellular proteins (i.e. EGF receptor, phospho-p38- and p44/42-MAPK) and the upregulation of EGFR expression. In human isolated bronchus, the presence of 1μM roflumilast inhibited EGF-induced MUC5AC mRNA and protein expression[8]. In A/J mice expressing wild type cystic fibrosis transmembrane conductance regulator (CFTR) and exposed to cigarette smoke or air, acute roflumilast (30nM) treatment increased CFTR-dependent chloride transport in both smoke- and air-exposed mice as compared to vehicle-treated group. Oral administration of roflumilast (5mg/kg/day, once per day) for five weeks activated CFTR and completely reversed cigarette smoke-induced adverse effects in vivo[9].
作用机制 The difluromethoxy group of roflumilast binds at the Q1 pocket of enzyme, while the cyclopropyl methoxy group binds at the Q2 pocket[7].
