The present review focused on the strategies aimed to possibly solve toxicity problems of distamycins. Distamycins are compounds characterized by an oligopeptidic pyrrolocarbamoyl frame ending with an amidino moiety. This class of compounds displays antiviral and antibiotic activity and shows interesting antiprotozoal activity related to the ability to reversibly bind to the minor groove of DNA with a high selectivity for TA-rich sequences. In consideration of their potential therapeutic properties, the synthesis of new distamycin derivatives and especially the development of controlled delivery strategies, could lead to important advantages in the clinical use of these molecules, possibly overcoming or mitigating the low solubility, specificity and toxicity problems associated with their use. To these aims an ensemble of the main synthetic distamycin derived compounds and of the potential drug delivery systems for distamycins described in literature is reviewed.
