Scientific Background Thiolutin is a sulfur antibiotic. Studies show the potential transcriptional inhibition on yeast degradation. By calculating the mRNA decay rates of transcription at different times after inhibition, it was evident that the effect of Thiolutin on the various degradation pathways of mRNA compromises the stability of the mRNA and the mechanism of gene expression (1). In pharmacology is known to inhibit endothelial cell adhesion by perturbing Hsp 27 interactions with components of the actin and intermediate filament cytoskeleton (2). Studies shown the inhibition of tumor cell-induced angionegesis in vivo, adhesion of endothelial cells to vitronectin ( IC50=0.83 µM) (3). Potentially inhibits developmental angiogenesis in zebrafish (2). Cell permeable. Active in vivo. Looking for more information on HSP27? Visit our new HSP27 Scientific Resource Guide at
