  • Patent number: 6716865
    Abstract: Benzoxa- and benzthiazoles substituted at the 2 position and carrying a sulfamic acid ester group bound via oxygen to the phenyl part of the ring structure, such as the compounds of formula (I) wherein the symbols have various significances, possess interesting pharmacological activity. They can be prepared by sulfamoylation of a corresponding compound carrying a hydroxy group on the phenyl part of the ring structure, or by N-substitution. They are indicated for use as steroid sulfatase inhibitors in the prevention and treatment of illnesses responsive to steroid sulfatase inhibition, such as acne.

  • Patent number: 6706727
    Abstract: The composition of formula I wherein the substituents have various significances, whereby one of R2 to R4 is ethyl. They can be prepared by fermentation, or by replacement of hydroxy with chloro under simultaneous or concomitant epimerization. They are indicated for use as pharmaceuticals in the prevention or treatment of inflammatory conditions and of conditions requiring immunosuppression, optionally in combination or association with further pharmaceutically active and compatible agents, e.g. macrolactam macrolides such as pimecrolimus.
