HUMAN HSP90 WITH 4-CHLORO-6-(4-PIPERAZIN-1-YL-1H-PYRAZOL-3-YL)-BENZENE-1,2-DIOL
|
OverviewOverview
Novel piperazinyl, morpholino and piperidyl derivatives of the, pyrazole-based Hsp90 inhibitor CCT018159 are described. Structure-activity, relationships have been elucidated by X-ray co-crystal analysis of the new, compounds bound to the N-terminal domain of human Hsp90. Key features of, the binding mode are essentially identical to the recently reported potent, analogue VER-49009. The most potent of the new compounds has a, methylsulfonylbenzyl substituent appended to the piperazine nitrogen, possesses an IC50 of less than 600 nM binding against the enzyme and, demonstrates low micromolar inhibition of tumour cell proliferation.
