- Mapping the substrate scope of monoamine oxidase (MAO-N) as a synthetic tool for the enantioselective synthesis of chiral amines
-
A library of 132 racemic chiral amines (α-substituted methylbenzylamines, benzhydrylamines, 1,2,3,4-tetrahydronaphthylamines (THNs), indanylamines, allylic and homoallylic amines, propargyl amines) was screened against the most versatile monoamine oxidase (MAO-N) variants D5, D9 and D11. MAO-N D9 exhibited the highest activity for most substrates and was applied to the deracemisation of a comprehensive set of selected primary amines. In all cases, excellent enantioselectivity was achieved (e.e. >99%) with moderate to good yields (55–80%). Conditions for the deracemisation of primary amines using a MAO-N/borane system were further optimised using THN as a template addressing substrate load, nature of the enzyme preparation, buffer systems, borane sources, and organic co-solvents.

- INHIBITOR OF JAK1 AND JAK2
-
The present invention provides an amino pyrazole compound, which is 3-[(lR)-6-fluoro-2,3-dihydro-1H-inden-l-yl]-N-(3- methyl-IH- pyrazol-5-yl)-3H-imidazo[4,5-b]pyridin-5-amine, or a pharmaceutically acceptable salt thereof, that inhibits JAK1 and JAK2 and, therefore may be useful in treating cancer.
