权利人:Monroe Mary Beth; PETRYK NATALIE M
摘要:A degradable polyurethane (PUr) having degradation rates useful for hemostatic dressings for controlling bleeding in traumatic wounds. Degradable PUrs may be synthesized from degradable monomers based on hydrolytically labile esters and oxidatively labile thioethers using rapid click-chemistry reactions. Monomers may include trimethylolpropane tris(3-mercaptopropionate) (TMPMP), dipentaerythritol hexakis(3-mercaptopropionate) (DPEHMP), dipentaerythritol hexakis(3-mercaptopropionate) (DPEHMP) or 2,2'-(ethylenedioxy) diethanethiol reacted with hydroxyethyl acrylate, 3-buten-1-ol, 3-methyl-3-buten-1-ol, or 3-buten-2-ol. Synthesis of these monomers is rapid and has no byproducts or toxic catalysts that require removal, enabling polyol synthesis and immediate use in further polymerization

标 题:Synthesis of isoprenoids and derivatives

摘要:This disclosure generally relates to the use of enzyme combinations or recombinant microbes comprising same to make isoprenoid precursors, isoprenoids and derivatives thereof including prenylated aromatic compounds. Novel metabolic pathways exploiting Claisen, aldol, and acyioin condensations are used instead of the natural mevalonate (MVA) pathway or 1-deoxy-d-xylulose 5-phosphate (DXP) pathways for generating isoprenoid precursors such as isopentenyl pyrophosphate (IPP), dimethylallyl pyrophosphate (DMAPP), and geranyl pyrophosphate (GPP). These pathways have the potential for better carbon and or energy efficiency than native pathways. Both decarboxylative and non-carboxylative condensations are utilized, enabling product synthesis from a number of different starting compounds. These condensation reactions serve as a platform for the synthesis of isoprenoid precursors when utilized in combination with a variety of metabolic pathways and enzymes for carbon rearrangement and the addition/removal of functional groups. Isoprenoid alcohols are key intermediary products for the production of isoprenoid precursors in these novel synthetic metabolic pathways.

标题:Annatto extract compositions, including geranyl geraniols and methods of use

摘要:Annatto extract composition (AEC), including cis and trans geranyl geraniols (GG) and tocopherol-free C-5 unsubstituted tocotrienols (T3), increases the de novo synthesis of intermediate isoprenoid and distal protein products, including endogenous coenzyme Q10 (CoQ10), dolichols (DL) and all subsequent GG-prenylated and DL-glycosylated proteins, including GG-porphyrinated hemes. This intermediate and distal product replenishment by AEC reverses maladies of myotoxicity (of both drug and non-drug origins), including maladies that affect the muscle, kidney, eye, GI tract and skin, nerve, blood, and CoQ10-related syndromes of energetics and LDL protection. AEC anabolically increases the endogenous de novo CoQ10 synthesis via GG elongation/prenylation of side-chain and conversely CoQ10 catabolically increases the endogenous de novo GG synthesis via beta-oxidation of CoQ10. Also, such AEC decreases de novo synthesis and increases disposal of triglycerides (TG) in humans via PPAR activation and SREBP deactivation. Such drop in TG by AEC reverses maladies of insulin resistance (IR) and metabolic syndrome (MS), prediabetes, diabetes and diabetes-related cardiovascular diseases (CVD). GG activates PPAR and down regulates SREBP transcription factors. This AEC, containing GG, inhibits cancer growth whether or not GG involvement in protein prenylation is required.
