The interactions of three cationic water soluble copper(II) porphyrins, differing in peripheral substituents, with calf thymus DNA are described. Tetrakis(N-methylpyridinium-4-yl)porphinecopper(II) behaves as a simple intercalator under the conditions investigated, whereas tetrakis(4-N,N%,Nยฆ-trimeth
