Background

Target: Hsp70

IC50: N/A

TRC 051384, belonging to substituted 2-propen-1-one class, is a potent inducer of heat shock protein 70 (HSP70) [1]. Induction of HSP70 is a natural response of stressed cells that protects neuronal cells from a variety of insults including acute ischemia. Therefore, induction of HSP70 provides a potential target for the treatment of stroke [1].

In vitro: Induction of HSP70 by TRC 051384 (6.25, and 12.5 μM) involved heat shock factor-1 (HSF1) activation in HeLa cells and led to increasing chaperone and anti-inflammatory activity [1]. Moreover, TRC 051384 (10-50 μM) dose-dependently induced HSPA1B overexpression in endothelial cells as well as leucocyte origin [2].

In vivo: TRC 051384 (9 mg/kg, intra-peritoneal administration) treatment significantly decreased stroke-associated neuronal injury, disability, and increased survival in a rat model of transient ischemic stroke [1]. In addition, TRC 051384 (9 mg/kg, intra-peritoneal administration) delayed thrombus formation without increasing bleeding risk in WT mice [2].

Protocol

Cell experiment:

HeLa cell transiently co-transfected with heat shock elements-luciferase reporter and normalization vector, β-galactosidase are treated with vehicle or TRC051384 (12.5 and 25 μM) for 4 hours. Cell lysates are then prepared and analyzed for luciferase and β-galactosidase activity[1].

Animal experiment:

Rats: Injured hemispheres from vehicle treated animals and TRC051384 treated animals are collected at 10-hour post-initiation of tMCAo. Total RNA from each brain sample is extracted followed by cDNA preparation. Each sample of cDNA is analyzed[1].
