Novel DNA threading intercalators

摘要

The invention is directed to a compound having the general formula (I): wherein each of L_a and L_b is an independently selected from a linking moiety comprising 0 to 10 main chain atoms, optionally substituted; each of Z_a and Z_b is an independently selected complexing moiety comprising at least one nitrogen atom; either both or one of Z_a and/or Z_b is coordinatively bonded to a respective transition metal complex M_aV_a and M_bV_b through said nitrogen atom, wherein each of M_a and M_b is an independently selected transition metal, and each of V_a and V_b is an independently selected valence group.
