In this issue of Chemistry & Biology, Arrendale and coworkers demonstrate a new prodrug strategy for intracellular delivery of an α, α-(difluoromethylene)phosphonate phosphoserine mimic. The deprotected pseudo-phosphopeptide releases the pro-apoptotic FOXO3a-transcription factor from its 14-3-3-adaptor protein complex, resulting in leukemic cell death.
在本期《化学生物学》中,阿伦代尔及其同事展示了一种用于细胞内递送α,α-(二氟亚甲基)膦酸酯磷酸丝氨酸模拟物的新前药策略。脱保护的假磷酸肽从其14-3-3衔接蛋白复合物中释放促凋亡的FOXO3a转录因子,从而导致白血病细胞死亡。
