  • Patent number: 8932836
    Abstract: The disclosure provides transaminase polypeptides capable of converting the substrate, 2-(3,4-dimethoxyphenethoxy)cyclohexanone to the trans diastereomer product (1R,2R)-2-(3,4-dimethoxyphenethoxy)cyclohexanamine in at least a 2:1 diastereomeric ratio relative to the cis diastereomer (1R,2S)-2-(3,4-dimethoxyphenethoxy)cyclohexanamine. The disclosure also provides polynucleotides, vectors, host cells, and methods of making and using the transaminase polypeptides in processes for preparing (1R,2R)-2-(3,4-dimethoxyphenethoxy)cyclohexanamine and its analogs, which can product compounds can be further used to prepare the aminocyclohexylether compound, (3R)-1-[(1R,2R)-2-[2-(3,4-dimethoxyphenyl)ethoxy]cyclohexyl]pyrrolidin-3-ol, which is an ion channel blocker.

  • Publication number: 20090203922
    Abstract: The present invention describes an efficient and economical process for the preparation of a 2,3-disubstituted 2-phenyl-1h-phenantrho[9,10-d]imidazole derivative that is useful for the large scale production of material for preclinical and clinical use. The process of the present invention represents a convergent approach to generate the 2,3-disubstituted 2-phenyl-1h-phenantrho[9,10-d]imidazole derivative in high overall yield. The compound made by the process of the invention is an inhibitor of the microsomal prostaglandin E synthase-1 (mPGES-1) enzyme and is therefore useful to treat pain and/or inflammation from a variety of diseases or conditions, such as osteoarthritis, rheumatoid arthritis and acute or chronic pain.
