  • Patent number: 10888553
    Abstract: There is disclosed a platinum ion chelating dipyridoxyl compound according to Formula (I), or a pharmaceutically acceptable salt thereof, wherein the dipyridoxyl compound is uncoordinated or coordinated with a metal ion which is not a transition metal, for prevention or treatment of chemotherapy drug induced peripheral sensory neuropathy in a patient, wherein the chemotherapy drug comprises platinum ions. An example of such a chemotherapy drug is oxaliplatin. The drawbacks of previous metal complexed compounds containing manganese ions are eliminated. A more frequent use of the drug is possible since the problem in the prior art with accumulated manganese neurotoxicity is eliminated. The compounds can be administered both temporally and spatially separately from chemotherapy.
    Type: Grant

  • Patent number: 10869938
    Abstract: A method of determining the amount of intracellular manganese in the myocardium of an individual pre-administered with a manganese contrast agent, or a pharmaceutically acceptable salt thereof, comprising subjecting, the individual to a MRI procedure to assess the signal intensity (SI) of images, or more preferably the longitudinal relaxation rate, R1 throughout the myocardium.

  • Publication number: 20020090341
    Abstract: The invention provides a method of detecting myocardial ischemia in a human or a non-human body, said method comprising administering to said body a physiologically acceptable manganese complex or salt thereof, subjecting said body to a magnetic resonance imaging procedure capable of generating images with time intervals of less than 0.5 seconds and thereafter providing a series of images of the myocardium of said body whereby to identify regions of abnormal blood flow. The method in accordance with the invention is of use not only in detecting myocardial ischemia, but also in discriminating between reversibly and irreversibly injured myocardial tissues, thereby providing important information about myocardial viability, e.g. during or following a severe heart attack or coronary occlusion. The method of the invention also provides an effective means of monitoring reperfusion of the myocardium.

  • Patent number: 6147094
    Abstract: The invention relates to the use of certain chelating agents and their metal chelates and to the use of certain manganese containing compounds, in particular manganese chelates, in the manufacture of a therapeutic agent for use in reducing the cardiotoxicity of an antitumor agent. Such compounds are particularly effective in reducing the side-effects of anthracycline drugs and/or paclitaxel.
