U7D-1
Based on 1 Customer Validation
U7D-1 is a USP7 PROTAC degrader that induces selective proteasomal degradation of USP7. U7D-1 destabilizes and downregulates the expression of variant PRC1 complex subunits PCGF1, RING1A and PCGF6, and also slightly reduces the protein level of KDM2B. U7D-1 decreases cell viability, arrests neuroblastoma cells at the G0/G1 cell cycle phase, and downregulates the expression of target genes of PAX3::FOXO1 in FP-RMS cells. U7D-1 increases the level of cleaved PARP in FP-RMS cells, induces cell apoptosis (apoptosis), and upregulates the expression of muscle differentiation markers MYH1 and MYF5. U7D-1 inhibits the growth and proliferation of p53 wild-type and mutant cancer cells, and regulates the apoptosis pathway and E2F pathway. U7D-1 is applicable to studies on neuroblastoma, fusion-positive rhabdomyosarcoma, p53-mutant cancers and cancer-related research.

U7D-1 reduces cellular viability, induces G0/G1 cell cycle arrest, and destabilizes variant PRC1 complex subunits including PCGF1, RING1A, and PCGF6 in neuroblastoma cell lines[1].
U7D-1 treatment does not significantly reduce mRNA expression of PRC1 complex subunits in neuroblastoma cell lines, indicating reduced protein levels occur post-transcriptionally[1].
U7D-1 (0.1-10 μM, 5-500 nM, 1 μM; 2-24 h, 20 h following 2 h pre-treatment) induces dose- and time-dependent, CRBN-, neddylation-, and proteasome-dependent USP7 degradation in RS4;11 cells with a DC50 of 33 nM[3].
U7D-1 exhibits high proteome-wide selectivity for USP7 degradation in RS4;11 cells[3].
U7D-1 (0.5 μM) degrades USP7 in RH30 FP-RMS cells, induces apoptosis, reduces levels of the PRC1.1 subunit KDM2B, downregulates PAX3::FOXO1 target genes, and promotes myogenic differentiation[2].
U7D-1 (79.4 nM-4948.0 nM, 0.1-1 μM, 1 μM; 3 days, 24 h, 0-24 h) inhibits growth of p53 wild-type OCI-ly10, RS4;11, MV4;11, Reh, and MOLT4 cells with IC50 values from 79.4 nM to 4948.0 nM, and this activity is not completely p53-dependent, as it remains effective in p53-knockdown RS4;11 shP53 cells[3].
U7D-1 (1 μM; 24 h, 0-72 h) exerts antiproliferative activity in p53 mutant Jeko-1 cells by triggering apoptotic and E2F pathway changes, including up-regulation of apoptotic genes and time-dependent cleavage of caspase-3[3].
U7D-1 (53.5 nM-10675.0 nM, 0.1-10 μM; 3 days, 7 days, 24 h) inhibits growth of p53 mutant Jeko-1, Mino, RPMI-8226, Jurkat, SU-DHL-6, and CCRF-CEM cells with IC50 values from 1034.9 nM to 10675.0 nM, and this activity is CRBN-dependent, as demonstrated by reduced potency and impaired USP7 degradation in Jeko-1 CRBN KO cells[3].
U7D-1 efficiently degrades USP7 with a DC50 of 33 nM and significantly inhibits the proliferation of both p53 wild-type and mutant cancer cells[4].
U7D-1 efficiently degrades USP7 (DC50 = 33 nM) and exerts potent anti-proliferative activity against p53 mutant Jeko-1 (IC50 = 1034.9 nM) and Mino (IC50 = 1175.3 nM) cancer cells by regulating USP7's non-enzymatic functional regions[5].
