  • Publication number: 20150368223
    Abstract: A process for synthesis of enatiomerically pure or enatiomerically enriched or racemic mixture of (+and/or?) epicatechin echm and its intermediates, comprising the steps of: (i) obtaining penta-protected quercetin; (ii) reducing the penta-protected quercetin obtained from step (i); (iii) optionally deprotecting the compound of step (ii); (iv) reducing the compound obtained from step (ii) or step (iii) in the presence of a chiral/achiral reducing agent to obtain a chiral intermediate; (v) deprotecting and/or hydrogenation of the chiral intermediate obtained from step (iv) to obtain (?)-epicatechin; (vi) optionally simultaneously deprotecting and by drogenation of the compound obtained from step (ii) to obtain racemic epicatechin.

  • Patent number: 9187448
    Abstract: The present invention relates to compounds, compositions, and methods for treatment of conditions related to mitochondrial function. In various aspects, the present invention comprises administering one or more epicatechin derivatives in an amount effective to stimulate mitochondrial function in cells. The compounds, compositions, and methods described herein provide for reducing infarct size in the heart following permanent ischemia or ischemia/reperfusion event or method for delaying, attenuating or preventing adverse cardiac remodeling, and can assist in prevention of impaired mitochondria biogenesis and thus prevention of the consequences of impaired mitochondrial biogenesis in various diseases and conditions, as well as provide for the active therapy of mitochondrial depletion that may have already occurred.
