20100136635 | Method of Inducing Chirality to Epoxides Using 2,3:4,6 di-O-isopropylidene-2-keto-L-gulonic Acid Monohydrate - The present invention relates to a recyclable method to prepare chirally pure epoxides directly from olefins using a novel chiral acid 2,3:4,6-di-O-isopropylidene-2-keto-L-gulonic acid monohydrate as chiral inducer and anhydrous hydrogen peroxide in the form of urea hydrogen peroxide adduct (UHP) as oxidant and lipase enzyme as catalyst. Under the influence of lipase, the chiral acid 2,3:4,6-di-O-isopropylidene-2-keto-L-gulonic acid monohydrate is converted to per-acid in situ by the oxidant urea hydrogen peroxide which in turn transfers oxygen to olefin inducing chirality to the product epoxide. Using this technique, important epoxide building blocks of different industrially important compounds can be prepared with good yield and moderate enantioselectivity. Chiral epoxidation of olefins with environment friendly catalytic system that can be recycled is highly desirable in the context of Green Chemistry for preparation of many industrially important compounds. | 06-03-2010 |

20150218556 | COMPOSITIONS AND METHODS FOR TREATING PERIPHERAL ARTERIAL DISEASE - The present application discloses roles for miR-93 in treating hypoxia and ischemia. Endothelial cells (HUVEC) and myocytes (C2C12) expressed miR-93 and up-regulated miR-93 in response to hypoxia and serum starvation. Over-expression of miR-93 in HUVECs promoted cell proliferation, prevented hypoxia-induced apoptosis, and enhanced endothelial cell tube formation. miR-93 knockdown in HUVECs resulted in increased hypoxia-induced apoptosis and decreased tube formation. Over-expression or knockdown of miR-93 in myocytes resulted in reduced or increased hypoxia-induced apoptosis, respectively. Down-regulation of miR-93 in C57BL/6 mice with antagomiR resulted in attenuated perfusion recovery (% non-ischemic leg at day-21: Scramble 85.22.9 vs. AntagomiR-93 67.96). Over-expression of miR-93 in BALB/C mice improved perfusion recovery (% non-ischemic leg at day 21: PremiR-93 757.5 vs. Scramble 59.62.5). The present invention encompasses the use of miR-93 and regulation of miR-93 to treat and prevent hypoxia, ischemia, and other injuries, diseases, disorders, and conditions associated with ischemia. | 08-06-2015 |
