WB214
WB214 is an MDM2 and GSPT1 degrader with human MDM2 Ki >10 μM. WB214 induces a neo-interaction between MDM2 and the cereblon E3 ligase complex, triggering MDM2 ubiquitination, proteasomal degradation, and bystander p53 degradation, and does not bind MDM2’s p53 binding region. WB214 induces GSPT1 degradation, and exhibits anti-proliferative activity in leukemia cells. WB214 can be used for the research of leukemia.

WB214 (compound 11) (97 nM-10 μM; 72 h) potently inhibits RS4;11 human acute leukemia cell proliferation with an IC50 of 1.2 nM[1].
WB214 (1.2 nM-1 μM; 1-12 h) induces time- and dose-dependent degradation of MDM2 (DC50 = 4.1 nM) and p53 (DC50 = 29 nM) in RS4;11 human acute leukemia cells[1].
WB214 (100 nM; 6 h) mediated degradation of MDM2 and p53 in RS4;11 human acute leukemia cells depends on the CRBN E3 ligase and ubiquitin-proteasome system, with p53 degraded as a bystander due to its association with MDM2[1].
WB214 (97 nM-10 μM; 0.5 h) does not bind to the p53 binding pocket of purified MDM2 protein[1].
WB214 (100 nM) efficiently induces ternary complex formation between MDM2 and CRBN in RS4;11 human acute leukemia cells[1].
WB214 (increasing concentrations; 15 min) potently induces dose-dependent formation of ternary complexes between purified CRBN/DDB1 and MDM2 proteins[1].
WB214 (100 nM; 6 h) causes degradation of MDM2 and p53 that is abolished when co-treated with Lenalidomide (HY-A0003) or MG132 (HY-13259)[1].
WB214 (1.2-nM; 6-12 h) induces dose-dependent degradation of GSPT1 (DC50 = 0.64 nM) in RS4;11 human acute leukemia cells[1].

-
Result:Induced time-dependent degradation of MDM2 and p53, with detectable degradation observed as early as 4 h post-treatment with 100 nM, and near-complete MDM2 depletion by 8 h.
Exhibited dose-dependent degradation with a DC50 of 4.1 nM for MDM2 and 29 nM for p53 at 12 h.
Resulted in significant depletion of both MDM2 and p53 protein levels when treated at 1 μM for 6 h.
