报道了针对STAT3的SH2结构域的前体药物的合成。采用收敛策略,合成了磷酸酪氨酸替代物5-氯苯基-4-膦-二氟甲基肉桂酸酯的丙戊酰氧甲基膦双酯,并将其用于固体载体上制备的模拟肽片段的酰化反应。本文描述的两种前药抑制乳腺肿瘤细胞中STAT3的磷酸化。
The synthesis of prodrugs targeted to the SH2 domain of Stat3 is reported. Using a convergent strategy, the pivaloyloxymethyl phosphonodiester of pentachlorophenyl 4-phosphonodifluoromethylcinnamate, a phosphotyrosine surrogate, was synthesized and used to acylate peptidomimetic fragments that were prepared on solid supports. Two prodrugs described here inhibited the phosphorylation of Stat3 in breast tumor cells.
