and hydrolysis with a t1/2 = 44 min. A highly potent and selective inhibitor of protein tyrosine phosphatase 1B (PTP1B) with a nanomolar Ki has been reported, but this bis(difluoromethylphosphonate) lacks potential utility due to its exceedingly low membrane permeability at physiological pH. A prodrug of this inhibitor has been synthesized and evaluated in a cell-based assay. The prodrug exhibits nanomolar
我们的实验室最近报道了磷酸酪氨酸模拟物在细胞内递送的新型前药化学的发展。现在已经将该化学方法用于合成前药,该前药可在细胞内递送不可水解的二氟甲基膦酸酯部分。前药的活化产生二氟甲基膦酰胺酸根阴离子,该阴离子随后进行环化和水解,时间为t1 / 2 = 44分钟。已经报道了具有纳摩尔摩尔数的蛋白酪氨酸磷酸酶1B(PTP1B)的高效抑制剂,但是这种双(二氟甲基膦酸酯)由于在生理pH下具有极低的膜渗透性而缺乏潜在的实用性。该抑制剂的前药已经合成,并在基于细胞的分析中进行了评估。在此分析中,前药显示出纳摩尔PTP1B抑制活性,
