Water-soluble PDE4 inhibitors for the treatment of dry eye.
Bioorg.Med.Chem.Lett., 20:2928-2932, 2010

PubMed Abstract: PDE4 inhibitors have the potential to alleviate the symptoms and underlying inflammation associated with dry eye. Disclosed herein is the development of a novel series of water-soluble PDE4 inhibitors. Our studies led to the discovery of coumarin 18, which is effective in a rabbit model of dry eye and a tear secretion test in rats.
