Losmapimod (Standard)
Losmapimod (GSK-AHAB; GW856553X) (Standard) is the analytical standard of Losmapimod (HY-10402). This product is intended for research and analytical applications. Losmapimod (GSK-AHAB; GW856553X) is an orally active p38α/β MAPK inhibitor, with pKi values of 8.1 and 7.6 for p38α and p38β, respectively. Losmapimod reduces DUX4 expression, thus exerting efficacy in facioscapulohumeral muscular dystrophy. By inhibiting MAPK/NF-κB, Losmapimod reduces apoptosis of epileptiform hippocampal neurons, and exhibits anti-allodynia and anti-hyperalgesic activities. Losmapimod blocks the entry and fusion of Lassa fever virus (LASV). Losmapimod overcomes tyrosine kinase inhibitor resistance in non-small cell lung cancer (NSCLC). Losmapimod inhibits myocardial senescence and inflammation, and possesses cardioprotective activity against cardiotoxicity.
