title: Structure determination of MS-444; a new myosin light chain kinase inhibitor.
abstract: MS-444 is a novel myosin light chain kinase inhibitor, isolated from the culture broth of Micromonospora sp. KY7123. The structure of MS-444 was determined to be 5,8-dihydroxy-3-methyl-(9H)-naphtho[2,3-c]furan-4-one by means of spectral analysis.
