标 题 :Green chemistry synthesis of the malaria drug amodiaquine and analogs thereof
发明人：FORTUNAK JOSEPH MARIAN; KULKARNI AMOL ANANT; KING CHRISTOPHER

摘要:Methods are provided for a green chemistry one-pot synthesis of amodiaquine and amodiaquine analogs. The methods have a lower environmental impact, lower investment cost, reduced amounts of byproducts and impurities, and a shorter synthesis time, compared to current conventional synthesis methods. The methods reduce the total number of steps in the synthesis from four to five down to two, thereby simplifying production; and allow a reduced number of solvents and reagents to be used in production, thereby reducing the waste generated in the synthesis. The methods can reduce the waste to about 3-5 kilograms of waste generated per kilogram of product produced; and surprisingly improve the overall yield from 60-65% to greater than 90% as compared to the current conventional synthesis methods for amodiaquine and its analogs.

摘要:Provided herein is a simple, one-step, non-enzymatic synthesis of O-Acetyl-ADP-ribose (OAADPR) from NAD and sodium acetate in acetic acid. The extension of this reaction to other carboxylic acids, demonstrates that the reaction between NAD, and NAD analogs produces mixtures of the corresponding 2′- and 3′-carboxylic esters. Included are O-carboxyl-ADP-ribose compounds and corresponding methods of synthesis (e.g., O-propionyl-ADP-ribose, O-succinyl-ADP-ribose, O-malonyl-ADP-ribose), as well as non-adenosine nucleoside compounds.

摘要:The invention is directed to isopsoralen compound compositions that contain a variety of substitutions which yet permit their binding to nucleic acid polymers. Reaction conditions that activate these bound isopsoralens results in covalent crosslinking to the nucleic acid polymers. The resultant complex is inhibited from being a template for the template-directed enzymatic synthesis of a complementary nucleic acid polymer. Beside the isopsoralens compositions, the invention includes their synthesis, the nucleic acid complex production and detection, and the above inhibitory method of use of the isopsoralens.

摘要:The present invention relates to a method for promoting acetylglucosamine synthesis of Bacillus subtilis, which belongs to the field of genetic engineering. The present invention adopts the recombinant Bacillus subtilis BSGNKAP2 as a starting strain, exogenously introducing pyruvate carboxylase BalpycA derived from Bacillus cereus, eliminating the central carbon metabolism overflow of the Bacillus subtilis and avoiding the synthesis of the by-product acetoin; further, five exogenous reducing force metabolic reactions are introduced to replace the reaction of generating NADH in glycolysis pathway and tricarboxylic acid cycle to reconstruct intracellular reducing force metabolism, which specifically comprise glyceraldehyde-3-phosphate ferredoxin dehydrogenase, isocitrate NAD+ dehydrogenase, a malate quinone dehydrogenase, a ketoacid ferredoxin oxidoreductase and a nitrogenase ferritin. In a shake-flask fermentation process using a complex medium, acetylglucosamine yield of the recombinant strain BSGNKAP8 is 24.50 g/L, acetylglucosamine/glucose yield is 0.469 g/g, respectively 1.97 times and 2.13 times of those of the starting strain BSGNKAP2.
