摘要:
A novel route is described for the synthesis of N-methyl-3-hydroxy-3-(2-thienyl)propylamine IV, which can be used as a starting compound for the preparation of duloxetine. N-methyl-3-hydroxy-3-(2-thienyl)propylamine is synthesized via novel thiophene derivatives containing carbamate groups, I and IIa, as intermediates.

In addition, the invention relates to pharmaceutical preparations containing at least one of the compounds of the abovementioned formula or their salts or N-oxides with physiologically tolerable inorganic or organic acids and, if appropriate, pharmaceutically utilizable vehicles and/or diluents or excipients and also administration forms of the compounds of the abovementioned formula containing at least one of the compounds of this formula or their salts in the form of tablets, coated tablets, capsules, solutions for infusion or ampoules, suppositories, patches, powder preparations which can be employed by inhalation, suspensions, creams and ointments
摘要:
The invention relates to a method for determining the isoform composition of erythropoietin, comprising the following steps: a) isoelectrical focusing of a sample comprising erythropoietin in a gel over a pH range having a lower limit of 2.5 to 3.5 and an upper limit of 5 to 8, wherein the sample comprising erythropoietin originates from a culture supernatant of erythropoietin producing eukaryotic cells; b) transferring of the proteins comprised and separated in the gel to a membrane; c) verifying the erythropoietin bound to the membrane by specific antibodies; and to a method for in-process control of culture supernatants of erythropoietin producing eukaryotic cells during the fermentative production process.
摘要:
The present invention relates to a process for the fermentative continuous production of erythropoietin, where eukaryotic erythropoietin-producing cells are cultured in a perfusion reactor while retaining the cells, the glucose concentration in the culture supernatant being adjusted via the perfusion rate and the cell number via the cell retention rate and/or the outward transferal of defined amounts of cell-containing culture medium from the bioreactor within preset zones.
