2-Difluoromethylene-4-methylenepentanoic Acid, A Paradoxical Probe Able To Mimic the Signaling Role of 2-Oxoglutaric Acid in Cyanobacteria
摘要:
2-Difluoromethylene-4-methylenepentanoic acid (DFMPA), a seemingly deviated analog of 2-oxoglutaric acid (2-OG), could surprisingly mimic its signaling function in cyanobacteria. Computer modeling revealed the favorable binding of DFMPA toward the 2-OG receptor, NtcA, via mutual conformational changes, suggesting that structural alteration of 2-OG is tolerated for it to exercise its signaling role. This extremely useful finding could be exploited for the design of affinity probes with which to study new 2-OG receptors In related signaling pathways.
A method of treating cancer is described. The method includes administering a therapeutically effective amount of a TET2 activating compound or pharmaceutically acceptable salt thereof to a subject in need of treatment. The TET2 activating compounds are a-ketoglutarate derivatives. A method of treating or preventing cancer in a subject that includes the step of analyzing a biological sample to determine if cells of the biological sample exhibit a TET2 mutation in addition to administering a TET2 activator is also described.
