Biochem/physiol Actions

Netropsin is an unusual n-methylpyrrole-containing oligopeptide that binds to AT-rich sequences of dsDNA, especially in the minor groove. Thus, it protects such regions from DNase I and other endonucleases, and also inhibits topoisomerases. Netropsin disrupts the cell cycle, prolonging G and arresting in G.

Caution

Protect from light.

With a growing understanding of the microstructural variations of DNA, it has become apparent that subtle conformational features are essential for specific DNA molecular recognition and function. DNA containing an A-tract has a narrow minor groove and a globally bent

We use a variety of biophysical techniques to determine thermodynamic profiles, including hydration, for the unfolding of DNA stem-loop motifs (hairpin, a three-way junction and a pseudoknot) and their interaction with netropsin and random cationic copolymers. The unfolding thermodynamic data

A furan amino acid, inspired by the recently discovered proximicin natural products, was incorporated into the scaffold of a DNA-binding hairpin polyamide. While unpaired oligomers of 2,4-disubstituted furan amino acids show poor DNA-binding activity, furan (Fn) carboxamides paired with N-methylpyrrole

The specific DNA binding ligand netropsin selectively blocks dA-dT base pairs in clusters containing two or more consecutive thymine residues at the dNAase I cleavage sites of DNA. Using CD and UV absorption measurements it is shown, that at various
