  2,6-bis[4-(4-carboxyoxazol-2-yl)-oxazol-2-yl]pyridine 、 二乙烯三胺 在 copper(II) bis(trifluoromethanesulfonate) 、 2,6-二甲基吡啶 、 1-羟基苯并三唑 、 盐酸-N-乙基-Nˊ-(3-二甲氨基丙基)碳二亚胺 作用下， 以 N,N-二甲基甲酰胺 为溶剂， 反应 3.0h， 以15%的产率得到3,7,21,25-Tetraoxa-11,14,17,31,32,33,34,35-octazahexacyclo[25.3.1.12,5.16,9.119,22.123,26]pentatriaconta-1(31),2(35),4,6(34),8,19,22(33),23,26(32),27,29-undecaene-10,18-dione

  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.

  macrocyclic lactams comprised of a pyridine, four oxazoles and a phenyl ring. A derivative having a 2-(dimethylamino)ethyl chain attached to the 5-position of the phenyl ring was recently identified as a selective G-quadruplex stabilizer with excellent cytotoxic activity, and good in vivo anticancer activity against a human breast cancer xenograft in mice. Here we detail the synthesis of eight new
