KU-177 is a potent inhibitor of Hsp90 ATPase homologue 1 (Aha1), ablates Aha1-driven enhancement of Hsp90-dependent tau aggregation. KU-177 also disrupts Aha1/Hsp90 interactions (IC50=4.08 μM) without inhibition of Hsp90’s ATPase activity. KU-177 can be used for tauopathies research.

Description

KU-177 is a potent inhibitor of Hsp90 ATPase homologue 1 (Aha1), ablates Aha1-driven enhancement of Hsp90-dependent tau aggregation. KU-177 also disrupts Aha1/Hsp90 interactions (IC50=4.08 μM) without inhibition of Hsp90’s ATPase activity. KU-177 can be used for tauopathies research[1][2].

IC50 & Target

HSP90

 

In Vitro

KU-177 (50 μM; 48 h) hampers the proliferation of flow MRD-positive cells in both primary multiple myeloma (MM) and recurrent MM patient samples[1].
KU-177 (30 μM; 48 h) inhibits proteasome activity in AHSA1 WT/OE cells, PSMD2 WT/OE cells and ANBL6 WT/DR cells[1].
KU-177 abrogates the cellular proliferation and PI resistance induced by elevated AHSA1, and decreases the expression of CDK6 and PSMD2[1].
KU-177 (25 μM; 30 min; 37 ℃) inhibits recombinant P301L tau aggregation without inhibiting Hsp90 to refold luciferase[2].
KU-177 (10 μM; 24 h) exhibits the ability to disrupt interactions between Aha1 and Hsp90 in SH-SY5Y neuroblastoma cells and SK-BR-3 breast cancer cells, without significantly inhibition on Hsp90 client protein (Her2)[2].

Cell Proliferation Assay[1]

Cell Line: ARP1 and H929 WT and AHSA1-OE cells
Concentration: 1 nM-100 μM
Incubation Time: 24, 48, 72 hours
Result: Decreased multiple myeloma (MM) cell proliferation and PI resistance induced by AHSA1/HSP90 in vitro.

Cell Proliferation Assay[2]

Cell Line: SH-SY5Y neuroblastoma cells and Her2 overexpressing SK-BR-3 breast cancer cells
Concentration: 10 μM
Incubation Time: 24 hours
Result: Didn’t induce the degradation of Hsp90 client proteins Her2 (in SK-BR-3 cells), Cdk6, or pAktS473 (in SHSY5Y cells), nor induced the expression of Hsp70, a marker of the heat shock response.
In Vivo

KU-177 (1 mg/kg; i.p.; twice a week; 4 weeks), inhibits tumor growth and extends the survival of 5TMM3VT MM mice without significant toxicity. KU-177 shows stronger efficacy in vivo, combined with Bortezomib (HY-10227) (1 mg/kg; i.p.)[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 5TMM3VT mouse model (6-8 weeks old, C57BL/KaLwrij mice)[1]
Dosage: 1 mg/kg
Administration: Intraperitoneal injection; twice a week; sacrificed mice with hindlimb weakness immediately, about 4-5 weeks
Result: Inhibited the xenograft tumor growth of both ANBL6 WT/BTZ-DR cells.
Didn’t induce histopathological abnormities or lesions in main organs including heart, liver, spleen, lung and kidney.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
