GSPT1 degrader-19 is a molecular glue degrader targeting GSPT1, IKZF1 and IKZF3, with DC₅₀ values of 0.88 nM, 11.54 nM and 13.84 nM, respectively, in MM.1S multiple myeloma cells. GSPT1 degrader-19 induces cereblon (CRBN)-dependent ubiquitination and proteasomal degradation of IKZF1, IKZF3, GSPT1 and GSPT2, and also reduces ZFP91 protein levels via a CRBN-dependent pathway. GSPT1 degrader-19 exerts antiproliferative effects on cancer cells, induces global proteomic changes including downregulation of novel substrates, and exhibits activity against multiple myeloma and leukemia cell lines. GSPT1 degrader-19 can be used in research related to multiple myeloma and leukemia.

GSPT1 degrader-19 (1.0 μM; 18 h) potently downregulates IKZF3, GSPT1, and GSPT2, and significantly decreases ZFP91 and IKZF1 levels in MM.1S multiple myeloma cells^[1].
GSPT1 degrader-19 (1-10 μM; 96 h) exerts anti-proliferative activity in MM.1S multiple myeloma cells in a CRBN-dependent manner, as activity is abolished in CRBN knockout cells^[1].
GSPT1 degrader-19 (0.1-1.0 μM; 18 h) induces neosubstrate degradation in MM.1S multiple myeloma cells in a CRBN-dependent manner, as no degradation of GSPT1, IKZF1, or IKZF3 is observed in CRBN knockout cells^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
