YM-01

YM-01 is an allosteric Hsp70 inhibitor. It binds with in Hsp70's nucleotide binding domain, adjacent to ATP/ADP binding pocket. It inhibits J-stimulated ATP turnover rate. It blocks Hsc70-bag1 interaction both in vitro and in vivo and enhances binding of Hsp70 to misfolded proteins. It reduces tau levels in tau-overexpressed HeLa cells, endogenous tau in neuroblastoma cells, and endogenous tau in primary neuron from rTg4510 mice, with EC50's of low micromolar. It recovers long-term potentiation deficits in brain slices from rTg4510 mice. It also has anti-cancer activity, with an EC50 value of low micromolar against several cancer cell lines. It destabilizes oncoproteins in cells, including Akt and Raf-1. Looking for more information on HSP70? Visit our new HSP70 Scientific Resource Guide at http://www.HSP70.com.
