Abstract

The synthesis of three potent new antitumor agents is described: the A83586C-citropeptin hybrid (1), the A83586C-GE3 hybrid (2), and l-Pro-A83586C (3). Significantly, compounds 1 and 2 function as highly potent inhibitors of ß-catenin/TCF4 signaling within cancer cells, while simultaneously downregulating osteopontin (Opn) expression. A83586C antitumor cyclodepsipeptides also inhibit E2F-mediated transcription by downregulating E2F1 expression and inducing dephosphorylation of the oncogenic hyperphosphorylated retinoblastoma protein (pRb).
