Hsp90-IN-45
Hsp90-IN-45 is a Hsp90 inhibitor. Hsp90-IN-45 competitively binds to the ATP-binding site of purified Hsp90α with a Kd of 70 nM, blocks ATP hydrolysis, and disrupts Hsp90 client signaling. Hsp90-IN-45 inhibits ATPase activity of purified Hsp90α. Hsp90-IN-45 will be radiolabeled with 76/77Br for use as a radiotheragnostic agent for PET imaging and Meitner-Auger electron therapy. Hsp90-IN-45 can be used for the research of cancer.

Biological Activity
|
HSP90α |
Hsp90-IN-45 (Compound 21) (1-32 μM; 90 min) dose-dependently inhibits the Ahsa1-stimulated ATPase activity of purified Hsp90α[1].
Hsp90-IN-45 (5-320 nM; overnight) competitively binds to the ATP-binding site of purified Hsp90α with high affinity (Kd = 70 nM)[1].
Hsp90-IN-45 (1-100 μM; 24 h) penetrates MDA-MB-231 cells, induces a heat shock response (measured by Hsp27 upregulation) at 1 and 10 μM after 24 h, and inhibits Hsp90 client protein signaling (measured by p-ERK1/2 downregulation) at 100 μM after 24 h[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:MDA-MB-231 breast cancer cells
-
Concentration:1, 10, 100 μM
-
Incubation Time:24 h
-
Result:Strongly reduced p-ERK1/2 levels at 100 μM, indicating inhibition of Hsp90 client protein signaling.
Induced a significant increase in Hsp27 levels at 1 μM and 10 μM, triggering the heat shock response at lower concentrations than those required for client signaling inhibition.
