摘要：

Tetraguanidines (1 and 2) with an aromatic multilayered structure exhibit potent binding to a specific site of DNAs with binding constants of the order of 10(7) M-1 as deduced from Scatchard analysis of ultrafiltration data and simulation of CD titration curves. NMR spectra of the complexes indicated that 1 and 2 bind DNAs sequence-specifically at the minor groove, as predicted by computational docking studies. (C) 1998 Elsevier Science Ltd.
