LA1011
LA1011 is a heat shock protein (Hsps) co-inducer that selectively enhances heat shock-induced Hsp70, Hsp40, and Hsp27 expression. LA1011 exhibits neuroprotective effects in APPxPS1 transgenic Alzheimer's disease mice, preventing hippocampal neuronal loss, reducing tau pathology and neurofibrillary tangle accumulation in the hippocampus, decreasing amyloid plaque formation in the hippocampus, and increasing dendritic spine density in hippocampal CA1. LA1011 can be used for research on Alzheimer's disease.

In Vitro
LA1011 (5-10 µM) does not alter yeast Hsp90 ATPase activity[1].
LA1011 (5 µM; 30 min-17 h) co-induced Hsp70 promoter-driven YFP expression in SH-SY5Y-pHsp70-YFP cells under 42°C heat shock conditions[1].
LA1011 (5 µM; 1-16 h) selectively co-induces Hsp27, Hsp40, and Hsp70 in heat-shocked SH-SY5Y cells without altering Hsp levels under non-stressed conditions[1].
