20150284338 | INDUSTRIAL PROCESS FOR THE SYNTHESIS OF PYRIMIDINYL-PIPERAZINE DERIVATIVES - Our invention relates to trans-(4-{4-[2-(4-amino-cyclohexyl)-ethyl]-piperazin-1-yl}-5,6-dichloro-pyrimidin-2-yl)-methylamine dihydrochloride monohydrate, the process for the synthesis of this compound, the new (4,5-dichloro-6-piperazin-1-yl-pyirimidin-2-yl)-methylamine monohydrochlorid used as starting material in this synthesis, as well as the industrial process for the synthesis of trans-N-(4- {2-[4-(5,6-dichloro-2-methyl-amino-pyirimidin-4-yl-)piperazin-1-yl]-ethly}cyclohexyl-propionamide starting from trans-(4-{4-[2-(4-amino-cyclohexyl)-ethyl]-piperazin-1-yl}-5,6-dichloro-pyrimidin-2-yl)-methylamine dihydrochloride monohydrate. | 10-08-2015 |
20150057439 | METHODS FOR REFOLDING G-CSF FROM INCLUSION BODIES - New methods for the refolding of recombinant granulocyte colony stimulating factor (G-CSF) from inclusion bodies are disclosed. The methods comprise two refolding steps. In particular, the methods comprise the solubilising of G-CSF with a solubilising agent, the oxidative refolding (first refolding step) of G-CSF in the presence of the solubilising agent and an oxidizing agent, the efficient removal of the solubilising agent, and a second refolding step to complete the folding of G-CSF in the absence of the solubilising agent. Various methods are described for the efficient removal of the solubilising agent from partially refolded G-CSF. | 02-26-2015 |
