    Product Description

    LDN-57444 is an inhibitor of UCH-L1 activity (IC50 = 0.88, Ki = 0.4 μM) that demonstrates selectivity for UCH-L1 compared to UCH-L3 (IC50 = 25 μM).1 Loss of UCH-L1 activity causes cell death through the apoptosis pathway due to an impaired ubiquitin-proteasome pathway. LDN-57444-induced reduction of free ubiquitin has been shown to create dramatic alterations in synaptic structure and function, increasing spine size while decreasing spine density in hippocampal neurons.2
