Synthesis of 5,6-dihydro-4H
-benzo[d
]isoxazol-7-one and 5,6-dihydro-4H
-isoxazolo[5,4-c
]pyridin-7-one Derivatives as Potential Hsp90 Inhibitors
摘要:
A novel class of 5,6‐dihydro‐4H‐benzo[d]isoxazol‐7‐ones and 5,6‐dihydro‐4H‐isoxazolo[5,4‐c]pyridin‐7‐ones was designed, synthesized, and assayed to investigate the affinity toward Hsp90 protein. The synthetic route was based on a 1,3‐dipolar cycloaddition of nitriloxides, generated in situ from suitable benzaldoximes, with 2‐bromocyclohex‐2‐enones or 3‐bromo‐5,6‐dihydro‐1H‐pyridin‐2‐ones. Whereas all the compounds bearing a benzamide group on the bicyclic scaffold were devoid of activity, the derivatives carrying a resorcinol‐like fragment showed a remarkable inhibitory effect on Hsp90. Docking calculations were performed to investigate the orientation of the new compounds within the binding site of the enzyme.
