Thiazotropsin B (AcImPyiPr ThDp) shows similar self-assembly characteristics to thiazotropsin A (FoPyPyiPr ThDp), although it is engineered, by incorporation of imidazole in place of N-methyl pyrrole, to swap its DNA recognition target from 5'-ACTAGT-3' to 5'-ACGCGT-3'. Replacement of the formamide head group in thiazotropsin A by nicotinamide in AIK-18/51 results in a measureable difference in solution-phase self-assembly character and substantially enhanced DNA association characteristics. The structures and associated thermodynamic parameters of self-assembled ligand aggregates and their complexes with their respective DNA targets are considered in the context of cluster targeting of DNA by minor-groove complexes.
