cis-6-oxo-hexahydro-2-oxa-1,4-diazapentalene and cis-6-oxo-hexahydropyrrolo[3,2-c]pyrazole based scaffolds: design rationale, synthesis and cysteinyl proteinase inhibition.

Abstract:

:The 5,5-bicycles cis-6-oxo-hexahydro-2-oxa-1,4-diazapentalene 3 and cis-6-oxo-hexahydropyrrolo[3,2-c]pyrazole 4 were designed as rotationally restricted templates towards the preparation of inhibitors of CAC1 cysteinyl proteinases. The design strategy was exemplified through the solution and solid phase preparation of potent inhibitors of human cathepsin K and may potentially be applied to inhibitors of other CAC1 proteinases.
