HY-139514

RB-3	E1/E2/E3 Enzyme	Cancer
RB-3, a polycomb repressive complex 1 (PRC1) inhibitor, binds to RING1B-BMI1f, with a K_d of 2.8 μM .

HY-18643

TZ9 2 Publications Verification	E1/E2/E3 Enzyme Apoptosis	Cancer
TZ9 is a selective Rad6 inhibitor. TZ9 inhibits Rad6B-induced histone H2A ubiquitination, downregulates intracellular β-catenin, induces G2-M arrest and apoptosis, and inhibits the proliferation and migration of metastatic human breast cancer cells .

HY-160924

MS147	PROTACs BMI1 E1/E2/E3 Enzyme Histone Methyltransferase	Cancer
MS147 is a VHL-based PROTAC degrader of BMI1 and RING1B (polycomb repressive complex 1 core components). MS147 directly binds EED and VHL E3 ligase, recruiting the ligase to the EED-BMI1/RING1B complex to induce time-dependent, ubiquitination-mediated degradation of BMI1 and RING1B. MS147 reduces histone H₂A Lys119 mono-ubiquitination without altering histone H₃ Lys27 tri-methylation and inhibits cancer cells proliferation. MS147 can be used for the research of cancer, such as chronic myelogenous leukemia and b-cell lymphoma . (Pink: BMI1/RING1B ligand (HY-183634); Blue: VHL ligand (HY-125845); Black: linker)

HY-151799

P62-RNF168 agonist-1	p62 E1/E2/E3 Enzyme Apoptosis	Cancer
P62-RNF168 agonist-1 (compound 5a) is a low cytotoxicity P62-RNF168 agonist that enhances the interaction between P62 and RNF168. P62-RNF168 agonist-1 induces a reduction in *H2A* ubiquitination mediated by RNF168 and impairs homologous recombination-mediated DNA repair. P62-RNF168 agonist-1 also inhibits the growth of xenograft tumors in mice in a dose-dependent manner .

HY-163518

Antitumor agent-153	E1/E2/E3 Enzyme	Cancer
Antitumor agent-153 (compound 11b) is an optimized *H2A* histone ubiquitination inhibitor based on PRT4165 (HY-19817). Antitumor agent-153 inhibits the viability of human osteosarcoma U2OS cells and reduces histone H2A monoubiquitination, exhibiting anticancer activity .

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
