Key words
brensocatib - AZD7986 - dipeptidyl dipeptidase 1 inhibitor - cathepsin C inhibitor - COVID-19
Significance
Cathepsin C (CatC) is a cysteine dipeptidyl amino-peptidase that activates most tissue-degrading elastase-related serine proteases. The highlighted paper describes the discovery of brensocatib (AZD7986), a CatC inhibitor. Brensocatib is now a clinical candidate to impair protease-driven tissue degradation in COVID-19 (B.

Comment
While the paper includes some synthetic details, the potential manufacturing route depicted is taken from an earlier patent (WO 2015 110826 A1). The notable feature is the one-pot amidation (E → G) and amide dehydration reactions (G → H) used to construct the amidoacetonitrile moiety.
