Description:

A novel potent ubiquitin-specific protease USP1 inhibitor with IC50 of 78.1 nM, 5 times more potent than SJB2-043 in promoting ID1 degradation and cytoxicity in K562 cells; also increases the levels of Ub-FANCD2 and Ub-PCNA, and decreases the HR activity; triggers apoptosis in multiple myeloma cells via activation of caspase-3/8/9, degrades USP1 and downstream inhibitor of DNA-binding proteins as well as inhibits DNA repair via blockade of Fanconi anemia pathway and homologous recombination; downregulates multiple myeloma stem cell Notch-1, Notch-2, SOX-4, and SOX-2, and induces generation of more mature and differentiated plasma cells.

DC72826	Usp22i-S02	Usp22i-S02(USP22-IN-1, compound S02) is a potent inhibitor of ubiquitin specific peptidase 22 (USP22). It showed anticancer activity by suppressing Foxp3 expression in T-regulatory cells.
DC71668	Iu1-248	Iu1-248, a derivative of IU1, is a potent and selective ubiquitin specific peptidase 14 (USP14) inhibitor with an IC50 of 0.83 μM.
DC71045	FT709	FT709 is a potent and selective USP9X inhibitor, an IC50 of 82 nM. USP9X has been linked with centrosome function, chromosome alignment during mitosis, EGF receptor degradation, chemo-sensitization, and circadian rhythms.
DC70873	USP10 inhibitor Wu-5	USP10 inhibitor Wu-5 (Wu-5) is a novel small molecule USP10 inhibitor inducing the degradation of FLT3-mutated protein, directly interacts and inactivates USP10, the deubiquitinase for FLT3-ITD in vitro (IC50=8.3 uM) and in FLT3-ITD-positive AML cells.Wu-5 selectively inhibited the viability of FLT3 inhibitor-sensitive (MV4-11, Molm13) and -resistant (MV4-11R) FLT3-ITD-positive AML cells with IC50 of 3.794, 5.056, and 8.386 uM, respectively.Wu-5 (1-10 μM) dose-dependently induced apoptosis of MV4-11, Molm13, and MV4-11R cells through the proteasome-mediated degradation of FLT3-ITD.Combined treatment of Wu-5 and crenolanib produced synergistic cell death in FLT3-ITD-positive cells via the reduction of both FLT3 and AMPKα proteins.
DC70653	NJH-2-075	NJH-2-075 is an alkyne-functionalized probe of EN523, retains binding to OTUB1 in vitro.
DC70509	IMP-1710	IMP-1710 (IMP1710) is a potent, selective, covalent UCHL1 inhibitor with IC50 of 38 nM.IMP-1710 demonstrated exquisite selectivity in a cross-screening against 20 DUBs.IMP-1710 can profile activity of endogenous UCHL1 with excellent selectivity in cell types including endothelial cells (EA.hy926) and adenocarcinoma human alveolar basal epithelial cells (A549).IMP-1710 demonstrated >50% fibroblast–myofibroblast transition (FMT) inhibition (IC50=740 nM) in idiopathic pulmonary fibrosis (IPF), as well as αSMA inhibition.IMP-1710 is a powerful and selective probe to explore UCHL1 activity with potential application to substrate identification, mode of action studies, and cellular target profiling.
DC70503	iBAP-II	iBAP-II (BAP1 inhibitor II) is a next-generation, specific small molecule inhibitor of BAP1 histone H2A deubiquitinase activity with IC50 of <0.1 ug/mL.iBAP-II displays higher affinity for BAP1 than the closest UCH family member, UCHL5, and other deubiquitinases, such as USP5, USP7, USP8, TNFAIP3-catalytic domain, USP2-catalytic domain, Otubain-1, and Ataxin3.Inhibition of BAP1 via iBAP-II reduces ASXL3 protein stability in small cell lung cancer cells, without significant changes to ASXL1 and ASXL2 protein levels.iBAP-II suppresses ASCL1 expression in NCI-H1963 cells, along with the mRNA levels involving a handful of known ASCL1 transcriptional targeted genes, such as GRP, DMPK, RNF183, SCN3A, MYCL, and CACNA1A.iBAP-II exhibited more potent cell viability inhibition activity on four different BAP1-WT SCLC cell lines than iBAP.iBAP-II (50 mg/kg/d) significantly delayed the disease progression in SCLC xenograft model.
DC11506	USP25 and 28 inhibitor AZ-1	USP25 and 28 inhibitor AZ-1 (AZ1) is a potent, selective, dual USP25/28 inhibitor with IC50 of 0.7/0.6 uM, respectively; shows a high degree of selectivity over other deubiquitinases (USP4,7 etc.); demonstrates target engagement against both USP25 and USP28 in cells, elicits modulation of both the total levels and the half-life of the c-Myc oncoprotein in cells, and also induces apoptosis and inhibits cell viability in a range of cancer cell lines.
DC8319	Spautin 1	Spautin 1 is an inhibitor of autophagy; inhibits USP10 and USP13 activity (IC50 values are 0.6 and 0.7 μM respectively) and promotes degradation of Vps34 (class III PI 3-kinase) complexes.
DC10001	NSC632839	NSC632839 is a nonselective isopeptidase inhibitor, which inhibits USP2, USP7, and SENP2 with EC50s of 45±4 μM, 37±1 μM, and 9.8±1.8 μM, respectively.
