Description:	ML346 is an activator of Hsp70 expression and HSF-1 activity, with an EC50 of 4.6 μM for Hsp70. ML346 restores protein folding in conformational disease models, without significant cytotoxicity or lack of specificity. ML346 induces specific increases in genes and protein effectors of the heat shock response (HSR), including chaperones such as Hsp70, Hsp40, and Hsp27[1].
In Vivo:	ML346 suppress the aggregation of polyQ35 in a C. elegans model, suggesting the probe has efficacy in modifying protein aggregation and associated toxicity[1].
In Vitro:	ML346 is an activator of Hsp70, with an EC50 of 4600 nM in HeLa cells. ML346 (10 μM) restores proteostasis, restores CFTR-mediated iodide conductance, and enhances the correct folding of proteins expressed in two different cellular compartments[1]. ML346 (Compound F1) induces multiple responses and strongly induces Hsp70, the oxidative stress response genes (HO1 and GCLM), and a 2.5-fold upregulation of BiP in WT MEF cells. ML346 (0.5-25 μM) exhibits cytoprotective effects in cells after a 35 min severe heat shock, and also causes a two-fold protection from H2O2-induced apoptosis[2].
