It has been previously demonstrated that therapeutic inhibition of the prostaglandin E2 (PGE2)-degrading enzyme, 15-prostaglandin dehydrogenase (15-PGDH), was able to improve muscle strength in aged mice. Researchers from Epirium Bio Inc. have now reported the discovery and preclinical characterization an orally bioavailable small molecule inhibitor of 15-PGDH – MF-300 – being developed for the treatment of neuromuscular dysfunction.
