A series of diarylurea ligands were designed to interact selectively with G-quadruplexes and were synthesised using copper(I) catalysed ‘click’ chemistry to incorporate the 1,4-substituted 1,2,3-triazole ring into the core of the ligands; the optimal ligands demonstrate a high degree of selective telomeric G-quadruplex stabilisation and are not cytotoxic in several cancer cell lines.
设计了一系列二芳基脲配体,以选择性地与G-四重螺旋相互作用,并采用铜(I)催化的“点击”化学合成这些配体,将1,4-取代的1,2,3-三唑环引入配体的核心;最佳配体在稳定端粒G-四重螺旋方面表现出高度选择性,并且在多种癌细胞系中无细胞毒性。
