Mechanism of Action

Information	Tanespimycin (17-AAG) is a potent N-terminal HSP90 inhibitor. It affects AKT/GSK3β, JAK/STAT, and MAPK signaling pathways by inhibiting HSP90 chaperone function and degrading client proteins, effectively inhibiting cell proliferation, migration, and viral replication, and promoting apoptosis.

Frequently Asked Questions

Question 1:
What kind of subtypes does this compound inhibit? HSP90α or HSP90β ?

Answer:
It can inhibit both HSP90α and HSP90β, but it is unclear how much they are affected respectively. You should note that Hsp90 derived from tumor cells has a 100-fold higher binding affinity for this compound than that from normal cells according to this paper. http://www.nature.com.ezp-prod1.hul.harvard.edu/nature/journal/v425/n6956/full/nature01913.html

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
