| Abstract: | We present a simple method based on the Cu2+ induced unfolding of G‐quadruplex (G4) of human telomere sequence dAG3(T2AG3)3] to screen a number of 3,6‐bis(1‐methyl‐4‐vinylpyridinium)carbazole diiodide (BMVC) analogues for better G4 stabilizers. Using circular dichroism (CD), the screening results suggest that the tri‐cations of 9‐substituted BMVC derivatives are better G4 stabilizers than the bi‐cations of BMVC. In addition, 3,6‐bis(1‐methyl‐4‐vinylpyrazinium)carbazole diiodide (BMVC4) is likely a better core molecule than BMVC for G4 stabilizers. |
