Abstract

The synthesis of a 24-membered macrocyclic hexaoxazole via ring-closing metathesis is described. The target compound selectively stabilizes G-quadruplex DNA with no detectable stabilization of duplex DNA. An MTT cytotoxicity assay indicated that this unsaturated macrocyclic hexaoxazole exhibits significant cytotoxicity toward P388, RPMI 8402, and KB3-1 cell lines with IC50 values of 45, 25, and 38 nM, respectively.
