A series of 7-azaindol derivatives were designed based on the homologous 3D model of human acrosin. These compounds were synthesized and evaluated for their human acrosin inhibitory activities in vitro. Compounds 7a, 7i, 7j, 7k and 7n showed highly inhibitory activity against human acrosin. The three-dimensional structure-activity relationship was investigated through a CoMFA model, which provided valuable information to further study of potential human acrosin inhibitors.

An optimised cost-effective synthesis of the new antitussive drug, DF1012, is herewith reported. The new synthetic route to the key intermediate DF1005 is based on the unusual deprotection step of the 1-tert-butyl-3-cyano-7-azaindole intermediate, which can also be regarded as a convenient way for the industrial production of the expensive 7-azaindole 1. The second key intermediate, endo-tropanamine 6, was obtained in high yield by a novel one-pot stereoselective process using a Pd-catalysed reductive amination procedure.
