HPLC of Formula: 89972-77-0. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 4-(p-Tolyl)-2,2:6,2-terpyridine, is researched, Molecular C22H17N3, CAS is 89972-77-0, about Synthesis, structure, and DNA binding studies of copper(II) complexes of terpyridine derivatives.
Two Cu(II) complexes, [Cu(ttpy)2](ClO4)2 (1, ttpy = 4′-(p-Tolyl)-2,2′:6′,2”-terpyridine) and [Cu(Brphtpy)2](ClO4)2 (2, Brphtpy = 4′-p-Bromophenyl-2,2′:6′,2”-terpyridine), were synthesized and characterized for their DNA binding and cleaving ability. The crystal structure of complex 1 reveals an axially compressed six-coordinate geometry around Cu(II). In spite of having an axially compressed geometry, the polycrystalline EPR spectrum of complex 1 at 298 K shows g‖ > g⊥, indicating a dx2-y2 ground state for the Cu(II) complex. Both complexes 1 and 2 bind to CT DNA intercalatively with moderate binding strength (Kb = (8.4 ± 0.2) × 103 and (10.9 ± 0.2) × 104 M-1 (1 M = mol dm-3), resp.). Both of these complexes cleave plasmid DNA efficiently in the presence of peroxide.
