FL2-14
FL2-14 is a CRBN-dependent selective molecular glue degrader of GSPT2. FL2-14 specifically degrades GSPT2 by recruiting the CRBN E3 ligase to recognize the G-loop sequence on the target protein GSPT2. FL2-14 can be used in related research on colorectal cancer.

In Vitro
FL2-14 (10 μM; 16 h) downregulates the non-essential proteins GSPT2, FAM83F, and ZBTB39 in RKO WT cells, with preferential degradation of GSPT2. It loses the activity to degrade GSPT2 in RKO CRBN KO cells, indicating that its function is CRBN-dependent. It exhibits GSPT2-degrading activity in RKO cells stably overexpressing wild-type GSPT2 (GSPT2WT), but shows no degradation activity in cells overexpressing the GSPT2G566N mutant. It does not exert IKZF1-degrading activity in MV4.11 cells[1].
FL2-14 (1 nM-10 µM; 1-16 h) induces GSPT2 degradation in a concentration-dependent manner in RKO WT cells and HEK293T cells, and significant GSPT2 degradation is observed starting at 5 h post-treatment[1].
FL2-14 (1 nM-10 µM; 72 h) exhibits no significant cytotoxicity in RKO WT cells and HEK293T cells[1].

Cell Line:RKO WT, RKO CRBN KO, HEK293T cell lines
-
Concentration:1 nM, 10 nM, 100 nM, 1 µM, 10 µM
-
Incubation Time:1, 2, 3, 4, 5, 6, 8, 16 h
-
Result:Significantly downregulated the protein levels of GSPT2, FAM83F, and ZBTB39, and preferentially degraded GSPT2.
Failed to degrade GSPT2, proving that its action was dependent on CRBN in RKO CRBN KO cells.
Induced the degradation of GSPT2 in a concentration-dependent manner.
Obviously induced the degradation of GSPT2 after 5 h of treatment.
