标题:Electrochemical deblocking solution for electrochemical oligomer synthesis on an electrode array
发明人：MAURER KARL; COOPER JOHN J
权利人:CUSTOMARRAY INC
摘要:There is disclosed an electrochemical deblocking solution for use on an electrode microarray. There is further disclosed a method for electrochemical synthesis on an electrode array using the electrochemical deblocking solution. The solution and method are for removing acid-labile protecting groups for synthesis of oligonucleotides, peptides, small molecules, or polymers on a microarray of electrodes while substantially improving isolation of deblocking to active electrodes. The method comprises applying a voltage or a current to at least one electrode of an array of electrodes. The array of electrodes is covered by the electrochemical deblocking solution.

摘要:4-amino-6-tert.butyl-3-mercapto-1,2,4-triazin-5-one of the formula is produced by reacting pivaloyl cyanide and isobutylene in the presence of acetic acid and sulfuric acid, hydrolyzing the reaction mixture in the presence of water and reacting the trimethyl pyruvic acid formed with thiocarbohydrazide. The triazinone is an important intermediate product in the synthesis of the known herbicide 4-amino-6-tert.butyl-3-methylmercapto-1,2,4-triazin-5-one.

摘要:α-Ketocarboxylic acid N-acylamides of the formula n n R.sup.1 --CO--CO--NH--CO--R.sup.2 n n in which n R 1 is an optionally substituted aliphatic radical with up to 12 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 10 carbon atoms, an optionally substituted heterocyclic radical, and n R 2 is an optionally substituted aliphatic radical with up to 8 carbon atoms or an optionally substituted phenyl radical, n are prepared by reacting an acyl cyanide of the formula n n R.sup.1 --CO--CN n n with a carboxylic acid anhydride of the formula n n R.sup.2 --CO--O--CO--R.sup.2 n n in the presence of a strong acid, and then adding water to the reaction mixture. The products can be used directly in the synthesis of known herbicides.

权利人:BAYER AG
摘要:A process for the preparation of an α-ketocarboxylic acid N-tert.-butylamide of the formula n n R--CO--CO--NH--C(CH.sub.3).sub.3 n n in which n R is an aliphatic radical with up to 8 carbon atoms, a cycloalkyl radical with 3 to 6 carbon atoms, a phenyl or naphthyl radical or a heterocyclic radical, n comprising reacting an acyl cyanide of the formula n n R--CO--CN n n with tert.-butyl methyl ether of the formula n n (CH.sub.3).sub.3 C--O--CH.sub.3 n n at a temperature between about 0° and 80° C. in the presence of an acid which is capable of activating the ether of formula (III) under the reaction conditions to give a tert.-butyl carbonium ion, and then hydrolyzing the reaction mixture. Advantageously the acyl cyanide is pivaloyl cyanide or benzoyl cyanide and is reacted with an approximately equimolar amount of the ether in the presence of about 1.1 to 1.5 times the molar amount of concentrated sulphuric acid as the activating acid. The products are useful as intermediates in the synthesis of known herbicides.

标题:Use of non-canonical amino acids as metabolic markers for rapidly-dividing cells
发明人：TIRRELL DAVID; DIETERICH DANIELA C; LINK AARON J; SCHUMAN ERIN
权利人:CALIFORNIA INST OF TECHN
摘要:The invention provides methods, reagents and systems to preferentially mark fast-proliferating cells/tissues (such as cancer), by incorporating non-natural amino acids into proteins, preferably in vivo, using the endogenous protein synthesis machinery of an organism. The incorporated non-natural amino acids contain reactive groups for further chemical reagents, which may serve as a “handleâ€? to for a number of uses, such as imaging of cancer cells, targeting drugs to preferentially kill cancer cells, and proteomic analysis in the context of large scale or high throughput screening for candidate drug leads that affects the proliferation of a target cell, etc.

标题 :Reagents and methods for the highly-efficient synthesis and purification of biopolymers
发明人：SCHWARTZ DAVID A; WILLIAMS JIMMY H
权利人:OLIGO FOUNDRY INC
摘要:The present disclosure provides reagent compounds, reactive biopolymeric compounds, and methods of making and using these materials for the rapid and efficient synthesis and purification of biopolymeric compounds at low cost. The materials and methods yield highly pure synthetic biopolymeric compounds, including synthetic oligonucleotides and polypeptides, and reduce or eliminate the need for toxic solvents in the synthetic process.
