摘要:The present invention discloses a computer-implemented method for engineering fluorinase enzymes towards the synthesis of fluorophenyl compounds. Limited or no mechanistic details of fluorinase enzymes have hindered progress in understanding their catalytic mechanisms for synthesizing synthetic organofluorine compounds. Through a comprehensive computational screening process, specific methionine-sulfonium phenyl substrates, including [(3S)-3-amino-3-carboxypropyl][2,5-difluoro-4-(4-methoxy-2,4-dioxobutyl)phenyl]methylsulfonium, were designed and optimized using quantum chemical optimization techniques. This methodology uncovers crucial information on F— ion attack conformation and the catalytic mechanism of the substrate, leading to the formation of Methyl 3-oxo-4-(2,4,5-trifluorophenyl)butanoate. Furthermore, a protein sequence and 3D modeling-based enzyme screening process was employed to identify the most suitable enzyme for this substrate. The identified enzyme was then engineered using the mechanistic insights gained from the studies, resulting in improved substrate scope, stability and catalytic efficiency. This computer-based approach offers an efficient and precise alternative to traditional trial-and-error methods, advancing the field towards the successful synthesis fluorophenyl compounds.

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.

摘要:The invention relates to commercially viable process for the synthesis of key intermediates for the preparation of statins, in particular Rosuvastatin and Pitavastatin or respective pharmaceutically acceptable salts thereof. A new simple and short synthetic route for key intermediates is presented which benefits from the use of cheap and readily available starting materials, by which the conventionally most frequently used DIBAL-H as reducing agent can be avoided.

摘要:The present invention is based on the discovery that 2-deoxyribose-5-phosphate aldolase (DERA, EC 4.1.2.4) and variants thereof can be used to catalyze sequential asymmetric aldol reactions between a wide variety of donor and acceptor aldehydes. The reaction products typically contain at least two new stereogenic centers and can be produced in enantiomerically pure form. As such, DERA catalyzed asymmetric aldol chemistry can be exploited to produce synthons for the synthesis of a variety of bioactive molecules.
