  • 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: 6289914
    Abstract: This invention refers to a microsplitter in flow systems especially used for separation techniques in analytical chemistry such as microliquid chromatography (MLC), high pressure liquid chromatography (HPLC) and ancillary techniques. The splitter system comprises a microsplitter and a micromixer which are connected by a microbore tubing. A high collection rate and high resolution of the sample peak are achieved by the proper choice of tubing length and diameters and the use of a back pressure regulator to obtain a controlled split ratio.
