  Medicinal Chemistry of Dihydropyran-Based Medium Ring Macrolides Related to Aspergillides: Selective Inhibition of PI3Kα

  摘要：

  A set of nine trans-disubstituted dihydropyran-based medium ring macrolides has been synthesized using D-glucal as chiral pool and evaluated against a panel of three human cancer cell lines and a normal cell line. The synthetic route to the targeted molecule is simple, concise, and high yielding compared to other reported methods. Bioevaluation studies have resulted in the identification of a potent cytotoxic molecule (10) exhibiting dose-dependent growth inhibition against HL-60 cell line with an IC50 value of 1.10 +/- 0.075 mu M, which is lower than that of naturally occurring molecules of this class and of comparable activity to the synthetic drug fludarubin. Compound 10 inhibits the PI3K/AKT signaling pathway by selectively targeting the p110 alpha subunit of PI3K alpha. This leads to mitochondrial stress that causes translocation of cytochrome c from mitochondria to cytosol, which in turn activates caspase-mediated apoptotic cell death. Further in silico docking simulations of four macrolides with p110 alpha subunits have been carried out to visualize the orientation pattern.
