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

This study examined the ability of netropsin and related minor groove binders to interfere with the actions of DNA topoisomerases II and I. We evaluated a series of netropsin dimers linked with flexible aliphatic chains of different lengths. These agents

Structural results with minor groove binding agents, such as netropsin, have provided detailed, atomic level views of DNA molecular recognition. Solution studies, however, indicate that there is complexity in the binding of minor groove agents to a single site. Netropsin
