  • Patent number: 6458837
    Abstract: The invention discloses stable diesters of chelating agents of divalent metal ions, processes for their preparation and pharmaceutical compositions thereof. Most preferred compounds according to the present invention are stable lipophilic diesters comprising a covalent conjugate of a BAPTA and a pharmaceutically acceptable alcohol. The diesters are useful in a method for treating a condition or disease related to an excess of divalent metal ions, and in particular for the treatment of a condition or disease related to elevated levels of intracellular calcium ions, such as in brain or cardiac ischemia, stroke, epilepsy, Alzheimer's disease or cardiac arrhythmia and in open heart surgery.

  • Patent number: 6413949
    Abstract: The invention relates to a pharmaceutically acceptable prodrug which is a covalent conjugate of a pharmacologically active compound and an intracellular transporting adjuvant, characterized by the presence of a covalent bond which is scission-sensitive to intracellular enzyme activity. The prodrug may be used in a technique for treating a condition or disease in a mammal related to supranormal intracellular enzyme activity, whereby on administering it to a human having such condition or disease, the bond is broken in response to such activity, and the pharmacologically active compound is activated selectively within cells having such supranormal intracellular enzyme activity.
