  • Title: B-Z transition of (dA-T)(n) duplexes induced by a spermine porphyrin-conjugate via an intermediate DNA conformation.
    Author: Sasaki H, Sasaki S.
    Journal: Chem Commun (Camb); 2013 Oct 11; 49(79):9024-6. PubMed ID: 23979223.
    Abstract:
    The spermine conjugate of the cationic porphyrin ligand (1) selectively induced the B-Z transition of the [(dA-T)n]2 sequence at low salt concentrations. The [(dG-C)n]2 sequence was not transformed into the Z-form. The B-Z transition was induced via an intermediate DNA conformation, which was formed by the external binding and formation of an assembly of 1 onto B-DNA.
