  • Patent number: 11708376
    Abstract: The disclosure provides compounds of Formula (I-A) and (I-B) and the pharmaceutically acceptable salts thereof. The variables, R, R2, R3, X1, X2, X3, Y1, Y, and Z are defined herein. Certain compounds of Formula (I-A) and (I-B) act as selective mitochondrial protonophore uncouplers that do not affect plasma membrane potential. These compounds are useful for treating or decreasing the risk of conditions responsive to mitochondrial uncoupling, such as cancer, obesity, type II diabetes, fatty liver disease, insulin resistance, Parkinson's disease, ischemia reperfusion injury, heart failure, non-alcoholic fatty liver disease (NALFD), and non-alcoholic steatohepatitis (NASH), Because mitochondrial uncouplers decrease the production of reactive oxygen species (ROS), which are known to contribute to age-related cell damage, the compounds are useful for increasing lifespan. Compounds and salts of Formulae (I-A) and (I-B) are also useful for regulating glucose homeostasis or insulin action in a patient.

  • Patent number: 7169818
    Abstract: The present invention is directed to compositions comprising lysophosphatidic acid analogs and methods of using such analogs as agonist or antagonists of LPA receptor activity. In addition the invention is directed to LPA receptor agonists that vary in the degree of selectivity at individual LPA receptors (i.e. LPA1, LPA2 and LPA3). More particularly the present invention is directed to LPA analogs wherein the glycerol is replaced with ethanolamine and a variety of substitutions have been linked at the second carbon atom.
