  • HY-139514
    RB-3

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

    MS181

    		PROTACs E1/E2/E3 Enzyme Cancer
    MS181 (compound 1) is a potent cereblon (CRBN)-recruiting and EED-binding polycomb repressive complex 1 (PRC1) PROTAC degrader. MS181 decreases the expression of EED, EZH2, SUZ12, BMI1 and RING1B. MS181 shows antiproliferative activity (Strtucture Note: Red, EED binder (HY-158771); Blue, CRBN ligand (HY-41547); Black, Linker HY-131717) [1].

    PRC1-IN-1

    		E1/E2/E3 Enzyme Others
    PRC1-IN-1 (compound RB-4) is an inhibitor of the polycomb repressive complex PRC1 (IC50=2.3 μM), targeting RING1B-BMI1, RING1A-BMI1, and RING1B-PCGF1 with IC50s of 2.8, 2.6, and 1.8 μM, respectively [1].

    MS147

    		PROTACs E1/E2/E3 Enzyme Cancer
    MS147 is a VHL-based PROTAC degrader of PRC1 (Polycomb Repressive Complex 1). The dissociation constants (Kd) of MS147 for EED (Embryonic Ectoderm Development) and VHL (Von Hippel-Lindau) are 3.0 μM and 450 nM, respectively. MS147 specifically binds to the EED protein through its EED-binding moiety; EED is a core component of PRC2 (Polycomb Repressive Complex 2) and interacts with the core components of PRC1, BMI1 (B-lymphoma Mo-MLV insertion region 1 homolog) and RING1B (Ring Finger Protein 1B). By this binding, MS147 is able to recruit BMI1 and RING1B near to VHL. Through the degradation of BMI1 and RING1B, MS147 reduces the level of H2AK119ub (histone H2A lysine 119 ubiquitination), affecting the proliferation of cancer cells. (Blue: VHL ligand (HY-125845), Black: linker ; Pink: PRC1 ligand (HY-158771)) [1].
