GSPT1 degrader-1
GSPT1 degrader-1 is a highly selective degrader targeting GSPT1. GSPT1 degrader-1 induces degradation via the ubiquitin-proteasome system. GSPT1 degrader-1 induces G0/G1 phase arrest, apoptosis (apoptosis) and inhibits proliferation in leukemia cells. GSPT1 degrader-1 reduces the levels of CDK6 and Cyclin B1, while increases the levels of activated caspase-3 and caspase-9 in leukemia cells. GSPT1 degrader-1 can be used in leukemia research.

GSPT1 degrader-1 (Compound 9q) (0-300 nM; 0-24 h) potently induces dose- and time-dependent degradation of GSPT1 in U937 acute myeloid leukemia cells, with a DC50 of 35 nM and the half-life of GSPT1 shortened to 6.3 h[1].
GSPT1 degrader-1 (0-300 nM; 6 h) potently induces dose-dependent degradation of GSPT1 in MOLT-4 acute lymphoblastic leukemia cells and MV4-11 acute myeloid leukemia cells[1].
GSPT1 degrader-1 (100 nM; 6 h) induces the degradation of GSPT1 in U937 acute myeloid leukemia cells via the ubiquitin-proteasome system[1].
GSPT1 degrader-1 (72 h) potently inhibits the proliferation of U937, MOLT-4 and MV4-11 leukemia cells, with IC50 values of 0.019, 0.006 and 0.027 μM, respectively[1].
GSPT1 degrader-1 (0-100 nM; 24 h) induces dose-dependent G0/G1 phase arrest and apoptosis in U937 acute myeloid leukemia cells, accompanied by decreased levels of CDK6 and cyclin B1, as well as increased levels of activated caspase-3 and activated caspase-9[1].
