Scientific context
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 more.

Additional description
Tissue, pathway, proteinase, peptidase, protease ,acrosin, lipoprotein, activator, caspase, trypsin, papain, esterase inhibitors are proteins or receptor ligands or receptor antagonists that bind to an enzyme receptor and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. Not all receptor antagonist that bind to enzymes are inhibitors; enzyme activator ligands or agonists bind to enzymes and increase their enzymatic activity, while enzyme substrates bind and are converted to products in the normal catalytic cycle of the enzyme.
