LDN 57444 is a reversible competitive inhibitor of ubiquitin C-terminal hydrolase L1 (Uch-L1) with IC50 value of 0.88μM [1].
Besides Uch-L1, LDN 57444 also inhibits Uch-L3 with a higher IC50 value of 25μM. The inhibition of Uch enzymes subsequently causes the reduction of long-term potentiation and basal synaptic transmission, which is similar to the alterations induced by Aβ [1].
In rat insulinoma cell line INS 832/13, treatment of LDN 57444 leads to the cell apoptosis. The increased activity of caspase-3 can be seen when the concentration of LDN 57444 is above 30μM. LDN 57444 also induces nuclear CHOP, suggesting that the apoptosis induced by the inhibition of Uch-L1 is related to ER stress [2].
