Materials and MethodsMaterials Tripeptide Synthesis. Synthesis of lysyl-5-fluoro-dL-tryptophyllysine was performed by the solid-phase method (Merrifield, 1964; Steward & Young, 1969) on Boc-L-Lys-(Cl-Z)-O-resin (Peninsula Laboratories, 2113R). The tert-butyloxycarbonyl (Boc) 1 derivative of 5-fluoro-DL-tryptophan1 Abbreviations: Boc, tert-butyloxycarbonyl; Z, benzyloxycarbonyl; CMC, carboxymethylcellulose; HPLC, high-pressure liquid chromatography; COSY, two-dimensional correlated spectroscopy; NOESY, twbdimensional nuclear Overhauser enhancement spectroscopy; CT DNA, calf thymus deoxyribonucleic acid (double stranded); EDTA, ethylene-diaminetetraacetic acid; SIS, solvent-induced shift (s);,, spin-lattice relaxation time; NOE, nuclear Overhauser effect; FTrp, 5-fluoro-DL-tryptophan; 5FTA, 5-fluorotryptamine; Tri (L), lysyl-5-fluoro-L-tryptophyllysine; Tri (o), lysyl-5-fluOro-D-tryptophyllysine; Tm, temperature at which the helix-to-coil transition ofDNA is 50% complete; TFA, tri-fluoroacetic acid; Tris, tris (hydroxymethyl) aminomethane; TBA, tert-butylamine.
