SP-187, also known as N-9-DNJ and UV-4B, is an alpha-Glucosidase inhibitor potentially for the treatment of dengue fever and influenza infection. Proline-producing strains of Serratia marcescens were more osmotolerant than wild-type strains. Growth inhibition by proline analogs was significantly enhanced by increasing the osmotic stress of the medium.
