On March 16, 2018, Ishoey, Mette; Chorn, Someth; Singh, Natesh; Jaeger, Martin G.; Brand, Matthias; Paulk, Joshiawa; Bauer, Sophie; Erb, Michael A.; Parapatics, Katja; Muller, Andre C.; Bennett, Keiryn L.; Ecker, Gerhard F.; Bradner, James E.; Winter, Georg E. published an article.COA of Formula: C14H10N2O6 The title of the article was Translation Termination Factor GSPT1 Is a Phenotypically Relevant Off-Target of Heterobifunctional Phthalimide Degraders. And the article contained the following:
Protein degradation is an emerging therapeutic strategy with a unique mol. pharmacol. that enables the disruption of all functions associated with a target. This is particularly relevant for proteins depending on mol. scaffolding, such as transcription factors or receptor tyrosine kinases (RTKs). To address tractability of multiple RTKs for chem. degradation by the E3 ligase CUL4-RBX1-DDB1-CRBN (CRL4CRBN), we synthesized a series of phthalimide degraders based on the promiscuous kinase inhibitors sunitinib and PHA665752. While both series failed to induce degradation of their consensus targets, individual mols. displayed pronounced efficacy in leukemia cell lines. Orthogonal target identification supported by mol. docking led us to identify the translation termination factor G1 to S phase transition 1 (GSPT1) as a converging off-target, resulting from inadvertent E3 ligase modulation. This research highlights the importance of monitoring degradation events that are independent of the resp. targeting ligand as a unique feature of small-mol. degraders. The experimental process involved the reaction of 2-(2,6-Dioxopiperidin-3-yl)-1,3-dioxoisoindoline-5-carboxylic acid(cas: 1216805-11-6).COA of Formula: C14H10N2O6
