  Synthesis and Evaluation of Silanediols as Highly Selective Uncompetitive Inhibitors of Human Neutrophil Elastase

  摘要：

  Chronic obstructive pulmonary disease (COPD) is an increasing health problem and is estimated to be the fifth leading cause of death in 2020 according to the World Health Organization. Current treatments are only palliative, and therefore the development of new medicine for the treatment of COPD is urgent. Human Neutrophil Elastase (HNE) is a serine protease that is heavily involved in the progression of COPD through inflammatory breakdown of lung tissue. Consequently, inhibitors of HNE are of great interest as therapeutics. In this article, the development of silanediol peptide isosters as inhibitors of HNE is presented. Kinetic studies revealed that incorporation of a silanediol isoster in the inhibitor structure resulted in an uncompetitive mechanism of inhibition, which further resulted in excellent selectivity. The peculiar mechanism of inhibition and the resulting selectivity makes the presented inhibitors promising leads for the development of new FINE-inhibitor-based therapeutics for the treatment of COPD.

  Further studies are reported on the utilization of the versatile reaction between chiral sulfinimines and alkyldiphenylsilyl lithium reagents with the goal of preparing a wide range of silanediol-based protease inhibitors. In particular, focus has been placed to demonstrate how a number of genetically encoded amino acid side chains such as serine, threonine, tyrosine, lysine, proline, arginine, aspartate

  Chiral alpha-silylsulfinamides, prepared by the treatment of an alkyldiphenylsilane with lithium followed by its addition to a sulfinimine, can be applied to the synthesis of 1,3-azasilaheterocycles as derivatives of cyclic alkaloids. This synthetic route, which involves intramolecular substitution of an amino alcohol or cyclization of an amino acid promoted by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC), represents a convenient means for accessing these silicon-containing heterocycles.
