First in Class, Potent, and Orally Bioavailable NADPH Oxidase Isoform 4 (Nox4) Inhibitors for the Treatment of Idiopathic Pulmonary Fibrosis
摘要:
We describe the design, synthesis, and optimization of first-in-class series of inhibitors of NADPH oxidase isoform 4 (Nox4), an enzyme implicated in several pathologies, in particular idiopathic pulmonary fibrosis, a life-threatening and orphan disease. Initially, several moderately potent pyrazolopyridine dione derivatives were found during a high-throughput screening campaign. SA R investigation around the pyrazolopyridine dione core led to the discovery of several double-digit nanomolar inhibitors in cell free assays of reactive oxygen species (ROS) production, showing high potency on Nox4 and Nox1. The compounds have little affinity for Nox2 isoform and are selective for Nox4/1 isoforms. The specificity of these compounds was confirmed in an extensive in vitro pharmacological profile, as well as in a counterscreening assay for potential ROS scavenging. Concomitant benefits are good oral bioavailability and high plasma concentrations in vivo, allowing further clinical trials for the potential treatment of fibrotic diseases, cancers, and cardiovascular and metabolic diseases.

Methods of preserving and/or protecting pancreatic beta cells by inhibiting NOX-1. In a further aspect, NOX-1 inhibitors are administered to a subject in order to preserve and/or protect beta cells in the prevention or treatment of diabetes. NOX-1 inhibitors are also disclosed; The method can be used to preserve beta cell/islet survival in vitro, or in vivo in cells exposed to stressful stimuli including but not limited to inflammation, inflammatory cytokines, high glucose, or elevated free fatty acids.
