Matrix metalloproteinases (MMPs) are well-established targets for several pathologies. In particular, MMP-2 and MMP-13 play a prominent role in cancer progression. In this study, a structure-based screening campaign was applied to prioritize metalloproteinase-oriented fragments. This computational model was applied to a representative fragment set from the publically available EDASA Scientific compound

Selective inhibitors of phosphoinositide 3-kinase delta are of interest for the treatment of inflammatory diseases. Initial optimization of a 3-substituted indazole hit compound targeting the kinase PIM1 focused on improving selectivity over GSK3 beta through consideration of differences in the ATP binding pockets. Continued kinase cross-screening showed PI3K delta activity in a series of 4,6-disubstituted indazole compounds, and subsequent structure activity relationship exploration led to the discovery of an indole-containing lead compound as a potent PI3K delta inhibitor with selectivity over the other PI3K isoforms.
