Description
Benzisoxazole Hsp90 inhibitor is an inhibitor of heat shock protein 90 (Hsp90; IC
50 = 30 nM in a fluorescence polarization assay). It is selective for Hsp90 over a panel of kinases (IC
50s = >20 μM). Benzisoxazole Hsp90 inhibitor inhibits the proliferation of HCT116, SK-BR-3, LNCaP, DU145, and H157 cancer cells (IC
50s = 0.28, 0.37, 0.17, 0.29, and 0.23 μM, respectively). It also induces degradation of the Hsp90 targets HER2 and the androgen receptor in SK-BR-3 and LNCaP cells, respectively, with an IC
50 value of 0.33 μM for both.
Definition
ChEBI: 4-chloro-6-{5-[(2-morpholin-4-ylethyl)amino]-1,2-benzisoxazol-3-yl}benzene-1,3-diol is a member of the class of 1,2-benzoxazoles carrying 2,4-dihydroxy-4-chlorophenyl and (2-morpholin-4-ylethyl)amino substituents at positions 3 and 5 respectively. It has a role as a Hsp90 inhibitor. It is a member of 1,2-benzoxazoles, a member of morpholines, a member of resorcinols, a member of monochlorobenzenes, a tertiary amino compound, a secondary amino compound and an aromatic amine.
