Synthesis of Phosphatase-Stable, Cell-Permeable Peptidomimetic Prodrugs That Target the SH2 Domain of Stat3
摘要:
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.
Disclosed are 4-(difluoromethylene)phosphonate cinnamic acid derivatives as a molecular scaffold for the preparation of protein tyrosine phosphatase inhibitors. The invention also relates to a process for the combinatorial preparation of protein tyrosine phospatase inhibitors possessing a 4-(difluoromethylene)phosphonate cinnamic acid/ester molecular scaffold.
