Hoechst 34580 tetrahydrochloride是一种细胞渗透性的荧光染料，用于DNA和核染色。

Hoechst 34580 tetrahydrochloride is a cell-permeable fluorescent dye for staining DNA and nuclei.

Solid

Amyloid-β

Hoechst 34580 prefers to locate near hydrophobic regions with binding affinity with the inhibition constant IC50 of 0.86±0.05 μM for Hoechst 34580. Hoechst 34580 is a good candidate for treating the Alzheimer’s disease by inhibiting Aβ formation. 50 μM Aβ42 solutions co-incubated with 100, 25, 12.5, 3.125, 0.78, and 0.1, 0.01 μM Hoechst 34580 at 37 °C for 70 h. Hoechst 34580 can inhibit the aggregation of Aβ42 in a dose-dependent manner. And the half-maximal concentration (IC50) is examined. The IC50 is obtained by measuring the concentration of Hoechst 34580 while maintaining the Aβ42 concentration which gave 0.86±0.05 μM for Hoechst 34580. has not independently confirmed the accuracy of these methods. They are for reference only.
