  Macrocyclic Pyridyl Polyoxazoles: Selective RNA and DNA G-Quadruplex Ligands as Antitumor Agents

  摘要：

  The synthesis of a series of 24-membered pyridine-containing polyoxazole macrocycles is described. Seventeen new macrocycles were evaluated for cytotoxic activity against RPMI 8402, KB-3, and KB-3 cell lines that overexpress the efflux transporters MDR1 (KBV-1) and BCRP (KBH5.0). Macrocycles in which the pyridyl-polyoxazole moiety is linked by a 1,3-bis(aminomethyl)phenyl group with a 5-(2-aminoethyl)- (18) or a 5-(2-dimethylaminoethyl)- substituent (19) displayed the greatest cytotoxic potency. These compounds exhibit exquisite selectivity for stabilizing G-quadruplex DNA with no stabilization of duplex DNA or RNA. Compound 19 stabilizes quadruplex mRNA that encodes the cell-cycle checkpoint protein kinase Aurora A to a greater extent than the quadruplex DNA of a human telomeric sequence. These data may suggest a role for G-quadruplex ligands interacting with mRNA being associated with the biological activity of macrocyclic polyoxazoles. Compound 19 has significant in vivo anticancer activity against a human breast cancer xenograft (MDA-MB-435) in athymic nude mice.
