Pyrrolepolyamide- -deoxyguanosine hybrids (Hybrid 2 and Hybrid 3) incorporating the 3-aminopropionyl or 3-aminopropyl linker were designed and synthesized on the basis of previously reported results of a pyrrolepolyamide-adenosine hybrid (Hybrid 1). Evaluation of the DNA binding sequence selectivity of pyrrolepolyamide- -deoxyguanosine hybrids was performed by CD spectral and analyses. It was shown that Hybrid 3 possessed greater binding specificity than distamycin A, Hybrid 1 and Hybrid 2.
