  • Publication number: 20220331273
    Abstract: Methods of quantifying a N2-(1-carboxyethyl)-2?-deoxyguanosine (CEdG) levels in biological samples and comparing those levels to known normal levels can diagnose a number of metabolic disorders or complications associated therewith, including diabetes, its associated complications, and cancer. Methods can also determine whether therapies for disorders are effective by measuring CEdG levels before and after treatment. Measurement of CEdG levels is achieved by using liquid chromatography electrospray ionization tandem mass spectrometry.

  • Patent number: 8580854
    Abstract: Accelerated formation of advanced glycation/lipoxidation end products (AGEs/ALEs) has been implicated in the pathogenesis of various diabetic complications. Several natural and synthetic compounds have been proposed and tested as inhibitors of AGE/ALE formation. We have previously reported the therapeutic effects of several new AGE/ALE inhibitors on the prevention of nephropathy and dyslipidemia in streptozotocin (STZ)-induced diabetic rats. In this study, we investigated the effects of various concentrations of LR-90 on the progression of renal disease and its effects on AGE and receptor for AGE (RAGE) protein expression on the kidneys of diabetic STZ-rats. In vitro studies were also performed to determine if LR-90 could inhibit the expression of various pro-inflammatory mediators in human monocytic cells.

  • Patent number: 7652037
    Abstract: This invention relates to methods for lowering lipid levels in mammals using compounds that inhibit advanced glycation endproducts (AGEs), LR-9, LR-74 and LR-90. These compounds, which inhibit non-enzymatic protein glycation, also inhibit the formation of advanced lipoxidation endproducts (ALES) on target proteins by trapping intermediates in glycoxidation and lopoxidation and inhibiting oxidation reactions important in the formation of AGEs and ALEs.
