专利号:US-2006234990-A1 优先权日:1999-04-30 标题 :Compositions of boswellic acids derived from Boswellia serrata gum resin, for treating lymphoproliferative and autoimmune conditions 发明人:MAJEED MUHAMMED; BADMAEV VLADIMIR 权利人:SAMI LABS LTD 摘要:A method of treatment of lymphoproliferative and autoimmune disorders with a new composition of four boswellic acids including β-boswellic acid, 3-O-acetyl-β-boswellic acid, 11-keto-β-boswellic acid, and 3-O-acetyl-11-keto-β-boswellic acid. Boswellic acids of invention have been obtained in a novel industrial process from the gum resin of Boswellia serrata tree, providing standardized composition which inhibits DNA, RNA and protein synthesis of the target cell without cytotoxic effects. The composition of invention provides advantage of irreversible cytostatic therapy, equivalent to biological effects of a cytotoxic therapy without killing body cells.

In addition, the invention relates to the use of pentacyclic triterpenoic acids and derivatives thereof for producing a medicament for the treatment of PGE2-mediated diseases.
专利号:US-9458479-B2 优先权日:2009-12-11 标题 :Method for late introduction of the (8R) hydroxyl group carbapenem β-lactam antibiotic synthesis 发明人:TOWNSEND CRAIG ARTHUR; BODNER MICAH JEFFREY; PHELAN RYAN MARTIN; FREEMAN MICHAEL FRANCIS 权利人:UNIV JOHNS HOPKINS 摘要:The presently disclosed subject matter demonstrates that ThnG and ThnQ enzymes encoded by the thienamycin gene cluster in Streptomyces cattleya oxidize the C-2 and C-6 moieties of carbapenems, respectively. ThnQ stereospecifically hydroxylates PS-5 giving N-acetyl thienamycin. ThnG catalyzes sequential desaturation and sulfoxidation of PS-5, giving PS-7 and its sulfoxide. The ThnG and ThnQ enzymes are relatively substrate selective, but give rise to the oxidative diversity of carbapenems produced by S. cattleya , and orthologues likely function similarly in allied streptomyces.
