Burkholderia cepacia lipase is an excellent enzyme for the enantioselective hydrolysis of β-heteroaryl-β-amino esters
摘要:
The enantioselective (E > 200) lipase PS-catalysed hydrolysis of beta-heteroaryl-beta-amino esters is described. The reactions were performed with H2O (0.5 equiv) in either diisopropyl ether or tert-butyl methyl ether at 25 degrees C. The resulting beta-heteroaryl-substituted beta-amino acid enantiomers were formed in high enantiomeric excess (ee >= 97%) and in good yield (>= 40%). (c) 2009 Elsevier Ltd. All rights reserved.

The present invention relates to novel compounds of formula (I), and compositions capable of inhibiting PHD1 enzyme activity selectively over other isoforms, for example, PHD2 and/or PHD3 enzymes. The invention also relates to compounds of formula (I) for use in disorders such as muscle degeneration, colitis, IBD, and certain ischemias.
Disclosed are small molecule inhibitors of the formula (I): and the pharmaceutical compositions thereof and processes of making the same. The compounds are useful in treating various diseases and conditions involving chymase.
