    A novel dioxo-triazine series of cathepsin K inhibitors was identified from HTS. A rapid exploratory programme led to the discovery of potent and selective cathepsin K inhibitors, typified by compound 24 which displayed IC(50) values of 17nM against catK and >10,000nM in catL, catB and catS assays.
