MT16-001

MT16-001 is a selective, covalent inhibitor of deubiquitinating enzyme UCHL1 with IC50 of 580 nM, no inhibitory effect against UCHL3 (IC50>30 uM).MT16-001 inhibits structurally unrelated DUB USP30 with similar potency.MT16-001 showed cytotoxicity in human embryonic kidney cells (HEK293) with EC50 of 730 nM, effectively engaged UCHL1 in cells with EC50 of 550 nM.MT16-001 showed excellent selectivity for UCHL1 across the UCH family: UCHL1, UCHL3, UCHL5 and BAP1.
