Field of application
KH-4-43 is a small moelcule E3 CRL4 inhibitor and exhibits antitumor potential, directly and selectively binds to the purified E3 ROC1-CUL4A CTD complex with Kd of 83 nM.KH-4-43 weakly binds to the purified, highly related E3 ROC1-CUL1 CTD complex with Kd of 9.4 uM, >100-fold less potent than ROC1-CUL4A CTD, showed little effect on Ub thiol ester formation with E1/E2 Cdc34.KH-4-43 inhibited the ubiquitination of CK1α by CRL4CRBN in vitro. Treatment of cells with KH-4-43 caused accumulation of the E3 CRL4 substrate CDT1.KH-4-43 inhibited cell viability against a panel of tumor lines, NB-4, MV4-11, OVCAR-3, and CAPAN-2 cell with IC50 of 1.8, 3.0, 3.9, and 4.8 uM, respectively.KH-4-43 suppress the growth of human tumor xenografts in mice.

DC70103 MS.001 MS.001 is a small molecule that inhibits both the chaperone binding and ubiquitin ligase activity of C-terminus of Hsc70 interacting protein (CHIP) at low micromolar concentrations (IC50=3.3 uM).
DC39084 Mezigdomide(CC-92480) Mezigdomide is a cereblon E3 ubiquitin ligase modulating agent with potential immunomodulating and antineoplastic activities. Mezigdomide specifically binds to cereblon (CRBN), thereby affecting the ubiquitin E3 ligase activity, and targeting certain substrate proteins for ubiquitination. This induces proteasome-mediated degradation of certain transcription factors, some of which are transcriptional repressors in T cells. This leads to modulation of the immune system, including activation of T lymphocytes, and downregulation of the activity of other proteins, some of which play key roles in the proliferation of certain cancer cell types.
DC10146 CC-122(Avadomide) CC-122 is a novel agent for DLBCL with antitumor and immunomodulatory activity.CC-122 binds CRBN and degrades Aiolos and Ikaros resulting in a mimicry of IFN signaling and apoptosis in DLBCL.
DC74306 T0467 T0467 is a small molecule activator of PINK1-Parkin signaling, activates Parkin mitochondrial translocation in dopaminergic neurons and myoblasts (20 uM, 3h), does not induce mitochondrial accumulation of PINK1.
DC74305 Skp2-2 Skp2-2 is a small molecule inhibitor of Skp2-Cks1 interaction with IC50 of 27.8 uM, significantly and dose-dependently reduces the protein expression of Skp2 in cancer cells.
DC74303 MN714 MN714 is a cell-premeable prodrug of MN551 containing a pivaloyloxymethyl (POM) and covalent inhibitor of E3 ligase suppressor of cytokine signaling 2 (SOCS2).
DC74302 MN551 MN551 is a Cys111-specific, covalent ligand targeting the E3 ligase SOCS2 with ITC Ki value of 2.2 uM, blocks recruitment of cellular SOCS2 protein to its native substrate.
DC74300 BC18813 BC18813 (BC 18813) is a small molecule inhibitor of the E3 ubiquitin ligase subunit DCAF7, potently inhibits SARS-CoV-2 infection with IC50 of 48 nM in cell-based assays.
DC74299 BC18630 free base BC18630 free base (BC 18630) is a small molecule inhibitor of the E3 ubiquitin ligase subunit DCAF7, potently inhibits SARS-CoV-2 infection with IC50 of 39 nM in cell-based assays.
DC74298 BC18630 BC18630 (BC 18630) is a small molecule inhibitor of the E3 ubiquitin ligase subunit DCAF7, potently inhibits SARS-CoV-2 infection with IC50 of 39 nM in cell-based assays.
