Definitions

  • the present application relates to prodrug derivatives of 5-chloro-N - ( ⁇ (5S) -3- [2-fluoro-4- (3-oxomorpholin-4-yl) phenyl] -2-oxo-1,3-oxazolidine -5-yl ⁇ methyl) thiophene-2-carboxamide, process for their preparation, their use for the treatment and / or prophylaxis of diseases and their use for the preparation of medicaments for the treatment and / or prophylaxis of diseases, in particular thromboembolic diseases.
  • Prodrugs are derivatives of an active substance which undergo a single or multistage biotransformation of enzymatic and / or chemical nature in vivo before the actual active substance is released.
  • a prodrug residue is usually used to improve the property profile of the underlying active ingredient [P. Ettmayer et al., J. Med. Chem. 47, 2393 (2004)].
  • the design of the prodrug remainder as well as the desired release mechanism must be tailored very closely to the individual drug, the indication, the site of action and the route of administration.
