  • Patent number: 11840497
    Abstract: Methods of treating or suppressing mitochondrial diseases, such as Friedreich's ataxia (FRDA), Leber's Hereditary Optic Neuropathy (LHON), mitochondrial myopathy, encephalopathy, lactacidosis, and stroke (MELAS), Kearns-Sayre Syndrome (KSS), are disclosed, as well as compounds useful in the methods of the invention, such as 4-(p-quinolyl)-2-hydroxybutanamide derivatives. Methods and compounds useful in treating other disorders such as amyotrophic lateral sclerosis (ALS), Huntington's disease, Parkinson's disease, and pervasive developmental disorders such as autism are also disclosed. Energy biomarkers useful in assessing the metabolic state of a subject and the efficacy of treatment are also disclosed.

  • Publication number: 20220017432
    Abstract: Conjugates derived from non-steroidal anti-inflammatory drugs (NSAIDs) and methods of use thereof are disclosed, useful for, inter alia, identifying and localizing the site of pathology and/or inflammation responsible for the sensation of pain in a patient; for identifying the sites of primary, secondary, benign, or malignant tumors; and for diagnosing infection or confirming or ruling out suspected infection. The NSAID-based conjugates contain an imaging moiety. The conjugates concentrate at sites of increased cyclooxygenase expression, thus revealing the sites of increased prostaglandin production, which is correlated with pain and inflammation, and correlated with tumor presence and/or location. Identifying areas of increased COX expressing can also aid in screening for infections.
