Description and Uses
The ubiquitin C-terminal hydrolase L1 (UCH-L1) is a member of a family of de-ubiquitinating enzymes that can generate free ubiquitin from ubiquitin precursors via its ubiquitin ligase activity. By associating with free ubiquitin, it also prevents its degradation. Neuronal UCH-L1 has been linked to Parkinson’s disease, the development of tumors, and neuropathic pain. 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). 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.
LDN 57444 is an inhibitor of UCH-L1, an enzyme expressed by certain lung tumor-derived cell lines, suggesting that this enzyme plays a role in tumor progression.
