LDN-91946是一种有效的非竞争性的选择性泛素羧基末端水解酶-L1(UCH-L1)抑制剂，Kiapp为2.8μM.
LDN-91946 is a potent, selective and uncompetitive ubiquitin C-terminal hydrolase-L1 (UCH-L1) inhibitor with a Ki app of 2.8 μM[1].
LDN-91946 is inactive against UCH-L3 at 20 μM. LDN-91946 demonstrates no activity against TGase 2, Papain, and Caspase-3 at 40 μM[1]. There is no cytotoxicity when serum-starved Neuro 2A (N2A) cells are treated with LDN-91946 at concentrations as high as 0.1 mM[1].
