We report the design of optimal linker geometries for the synthesis of stapled DNA-minor-groove-binding molecules. Netropsin, distamycin, and lexitropsins bind side-by-side to mixed-sequence DNA and offer an opportunity for the design of sequence-reading molecules. Stapled molecules, with two molecules covalently linked side-by-side, provide entropic gains and restrain the position of one molecule relative to its neighbor. Using a free-atom simulated annealing technique combined with a discrete mutable atom definition, optimal lengths and atomic composition for covalent linkages are determined, and a novel hydrogen bond 'zipper' is proposed to phase two molecules accurately side-by-side.
