MG-277, a molecular glue degrader, effectively induces degradation of a translation termination factor, GSPT1, with a DC50 of 1.3 nM. MG-277 potently inhibits tumor cell growth in a p53-independent manner, with IC50s of 3.5 nM for RS4;11 cells and 3.4 nM for p53 mutant RS4;11/IRMI-2 cells, respectively. Anticancer activity[1].
MG-277 (0.03-10 nM; 24 hours; RS4;11 cells) treatment inhibits cell growth and degrades GSPT1[1].MG277 has a significantly decreased potency in reducing the level of MDM2 protein in cells and fails to activate wild-type p53. MG-277 is highly potent and effective in inhibition of cell growth in cancer cell lines with wild-type p53, mutated p53, or deleted p53, indicating a p53-independent mechanism. MG-277 induces rapid GSPT1 degradation in cancer cells in a p53- and MDM2-independent manner but in a manner dependent upon cereblon, CUL4 E3 ubiquitin ligase, and proteasomes[1].

Simple Structural Modifications Converting a Bona fide MDM2 PROTAC Degrader into a Molecular Glue Molecule: A Cautionary Tale in the Design of PROTAC Degraders
J Med Chem 2019 Nov 14;62(21):9471-9487.PMID:31560543DOI:PMC7354697
Inducing protein degradation by proteolysis targeting chimeras (PROTACs) has gained tremendous momentum for its promise to discover and develop new therapies. Based upon our previously reported PROTAC MDM2 degraders, we have designed and synthesized additional analogues. Surprisingly, we found that simple structural modifications of MD-222, a bona fide MDM2 PROTAC degrader, converts it into a "molecular glue", as exemplified by MG-277. MG-277 induces only moderate MDM2 degradation and fails to activate wild-type p53 but is highly potent in inhibition of tumor cell growth in a p53-independent manner. Our mechanistic investigation established that MG-277 is not a PROTAC MDM2 degrader but instead works as a molecular glue, inducing degradation of a translation termination factor, GSPT1 to achieve its potent anticancer activity. Our study provides the first example that simple structural modifications can convert a bona fide PROTAC degrader into a molecular glue compound, which has a completely different mechanism of action.
