PU-11
PU-11 is a Hsp90α/Hsp90β inhibitor with IC50 values of 18.6 μM and 89.8 μM and Kd values of 2 and 4.2 μM. PU-11 binds to the ATP-binding pocket of Hsp90α and Hsp90β and displays selective binding preference for Hsp90α over Hsp90β, mediated by the nonconserved Hsp90α Ser52 residue. PU-11 can be used for the research of neurodegenerative disorders.

In Vitro
PU-11 (Compound PU-11-trans) (30.1-50.7 μM) binds to purified human Hsp90α NTD with a Kd of 2.0 ± 0.14 μM and an IC50 of 18.6 μM, exhibiting selective affinity for this paralog[1].
PU-11 (93.3-97.8 μM) binds to purified human Hsp90β NTD with a Kd of 4.2 ± 0.74 μM and an IC50 of 89.8 μM, showing lower affinity than for Hsp90α[1].
PU-11 (33.0-41.8 μM) binds to purified human Hsp90αS52A mutant NTD with a Kd of 4.2 ± 0.03 μM, matching its affinity for wild-type Hsp90β[1].
PU-11 shows IC50 values of 111.4 ± 9.7 and 172.9 ± 7.3 μM for Grp94 and Trap-1[1].

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
