Biochem/physiol Actions

Paquinimod (ABR-215757) is an orally active quinoline-3-carboxamide (Q substance) class immunomodulator that targets S100A9 (Calgranulin B; MRP14) via direct binding and blocks its interaction with receptor for advanced glycation end products (RAGE) and Toll-like receptor 4 (IC50 = 26 μM & 23 μM against 100 nM hS100A9 from binding immobilized hRAGE & hTLR4/MD2, respectively). Paquinimod in vivo efficacy is demonstrated in murine models of autoimmune/inflammatory diseases, including liver fibrosis, collagen-induced osteoarthritis, peritonitis, EAE, type 1 diabetes, lupus (0.04-25 mg/kg/day p.o.), and atherosclerosis (10 mg/kg i.p.).

Quinoline-3-carboxamides (Q compounds) are immunomodulatory compounds that have shown efficacy both in autoimmune disease and cancer. We have in here investigated the impact of one such compound, paquinimod, on the development of diabetes in the NOD mouse model for type

Platelets play a critical role in atherogenesis and thrombosis-mediated myocardial ischemia, processes that are accelerated in diabetes. Whether hyperglycemia promotes platelet production and whether enhanced platelet production contributes to enhanced atherothrombosis remains unknown. Here we found that in response to

Quinoline-3-carboxamide compounds (Q compounds) have demonstrated efficacy in treating autoimmune disease in both humans and mice. However, the mode of action of these compounds is poorly understood. Here, we show that preventive treatment with the Q compound paquinimod (ABR-215757) during

Neutrophilic inflammation often persists for days despite effective antibiotic treatment and contributes to brain damage in bacterial meningitis. We propose here that myeloid-related protein 14 (MRP14), an abundant cytosolic protein in myeloid cells, acts as an endogenous danger signal, driving

Alarmins S100A8/A9 regulate pathology in experimental osteoarthritis (OA). Paquinimod is an immunomodulatory compound preventing S100A9 binding to TLR-4. We investigated the effect of paquinimod on experimental OA and human OA synovium. Two OA mouse models differing in level of synovial
