The linkage of an heterocycle, like N-methylimidazole, to minor DNA groove binders containing two or three pyrroles lead to a new class of oligopeptides with reduced antitumor activity both in vitro and in vivo if compared to tallimustine (CAS 115308-98-0) and its tetrapyrrole homologue 9. In the present paper is reported the correlation between the cytoxicity of tallimustine and its derivatives 9-11 with their ability to inhibit polymerase chain reaction (PCR) amplification of oestrogen receptor and Ha-ras gene sequences, containing A + T rich and G + C rich regions, respectively. Tallimustine and its tetrapyrrole homologue 9 were found to have higher sequence selectivity for the human oestrogen receptor (ER) gene with respect to the relative imidazole-containing analogues
