A small set of aggrecanase inhibitors based on the pyrrolo[3,4-c]quinolin-1-one or oxoisoindoline frameworks bearing a 4-(benzyloxy)phenyl substituent and different zinc binding groups were rationally designed and evaluated in silico by docking studies using the crystal structure of the ADAMTS-5 catalytic domain (PDB code: 3B8Z). The designed compounds were synthesized via straightforward routes and tested for their potential inhibitory activity against ADAMTS-5 and ADAMTS-4. Among the compounds containing the pyrrolo[3,4-c]quinolinone tricyclic system, hydroxamate derivative 2 b (I) inhibited both ADAMTS-5 and ADAMTS-4, with IC50 values in the submicromolar range and an inhibitory profile very similar to that of reference carboxylate derivative 11. Conversely, the corresponding carboxylate derivative 2 a was significantly less active and unable to discriminate between ADAMTS-5 and -4. The structure-activity relationship anal. of pyrroloquinolinone derivatives 2 a-i suggests that the carboxylate or hydroxamate groups of compounds 2 a,b play a key role in the interaction of these compounds with ADAMTS-5 and -4. On the other hand, the oxoisoindoline derivatives 3 a,b lack significant ADAMTS-4 inhibitory activity and inhibit ADAMTS-5 showing IC25 values in the micromolar range.
