权利人:UMICORE AG & CO KG
摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

标题:Scale up synthesis of silicasome nanocarriers

摘要:In order to facilitate the approval and commercialization of silicasome drug delivery systems (e.g. irinotecan silicasomes) it is necessary to scale up synthesis of the drug-loaded silicasomes. In this regard, it was discovered that the synthesis protocols used for laboratory synthesis of drug-loaded silicasomes (e.g., 500 mg/batch) do not scale to large scale silicasome production, because the resulting products were too heterogeneous for use as pharmaceuticals. Accordingly, new methods are provided herein that effectively afford the large-scale production of mesoporous silica nanoparticles (MSNPs) and lipid bilayer coated MSNPs (silicasomes).

标 题 :Lyophilized preparation for synthesis of cell-free protein
发明人：ENDO YAETA; OGASAWARA TOMIO
权利人:CELLFREE SCIENCES CO LTD
摘要:Lyophilized preparations from cell extract for use in cell-free protein, which exhibit an activity for protein synthesis being in no way inferior to that exhibited in low-temperature storage; and a method of utilizing the same. In particular, preparations are formed by performing lyophilization after reducing the concentration of deliquescent substances in a solution containing cell extract for synthesis of cell-free protein to a level not detrimental to the quality of preparations after lyophilization.

标 题:Synthesis of pancratistatin prodrugs
发明人：PETTIT GEORGE R; ORR BRIAN; DUCKI SYLVIE
摘要:A new and efficient synthesis of the (+)-pancratistatin phosphate prodrug 2 a has been accomplished. Selective protection (tetraacetate 4 ) of (+)-pancratistatin ( 1 a ) was followed by phosphorylation (to 5 ) with dibenzyl chlorophosphite (prepared in situ from dibenzyl phosphite). Cleavage of the acetate (with sodium methoxide) and benzyl (by hydrogenolysis) protecting groups followed by concomitant reaction with two equivalents of sodium methoxide afforded good yield of disodium (+)-pancratistatin phosphate ( 2 a ). Further increases in yields of the prodrug ( 2 a ) were realized by avoiding heat in the final purification steps. Fourteen ( 2 b - o ) additional metal and ammonium derived phosphate prodrugs were also synthesized.

摘要:The invention relates to a new process for the synthesis of amorphous atorvastatin calcium, which consists of dissolving the salt of the formula (I) of atorvastatin acid formed with a basic amino acid (I); in a mixture of water and a water miscible organic solvent, adding an aqueous solution of a water soluble calcium salt to the solution and isolating the so obtained entirely amorphous atorvastatin calcium of high purity by filtration.
