چکیده

Groove specificity. Pyrrole-imidazole polyamides are well-known for their specific interactions with the minor groove of DNA. Here we demonstrate that polyamides do not similarly bind duplex RNA, and offer a structural rationale for the molecular-level discrimination of nucleic acid duplexes by minor groove binding ligands.

Binding of hairpin pyrrole and imidazole polyamides to DNA: relationship between torsion angle and association rate constants

N-methylpyrrole (Py)-N-methylimidazole (Im) polyamides are small organic molecules that bind to DNA with sequence specificity and can be used as synthetic DNA-binding ligands. In this study, five hairpin eight-ring Py-Im polyamides 1-5 with different number of Im rings were synthesized, and their binding behaviour was investigated with surface plasmon resonance assay. It was found that associat...

Synthetic pyrrole-imidazole polyamide inhibits expression of the human transforming growth factor-beta1 gene.

Pyrrole-imidazole (Py-Im) polyamides can bind to the predetermined base pairs in the minor groove of double-helical DNA with high affinity. These synthetic small molecules can interfere with transcription factor-DNA interaction and inhibit or activate the transcription of corresponding genes. In the present study, we designed and synthesized a Py-Im polyamide to target -545 to -539 base pairs o...

Tumor Repression of VCaP Xenografts by a Pyrrole-Imidazole Polyamide

Pyrrole-imidazole (Py-Im) polyamides are high affinity DNA-binding small molecules that can inhibit protein-DNA interactions. In VCaP cells, a human prostate cancer cell line overexpressing both AR and the TMPRSS2-ERG gene fusion, an androgen response element (ARE)-targeted Py-Im polyamide significantly downregulates AR driven gene expression. Polyamide exposure to VCaP cells reduced proliferat...

RNA polymerase II senses obstruction in the DNA minor groove via a conserved sensor motif.

RNA polymerase II (pol II) encounters numerous barriers during transcription elongation, including DNA strand breaks, DNA lesions, and nucleosomes. Pyrrole-imidazole (Py-Im) polyamides bind to the minor groove of DNA with programmable sequence specificity and high affinity. Previous studies suggest that Py-Im polyamides can prevent transcription factor binding, as well as interfere with pol II ...

Toward rules for 1:1 polyamide:DNA recognition.

Polyamides composed of four amino acids, imidazole (Im), pyrrole (Py), hydroxypyrrole (Hp), and beta-alanine (beta), are synthetic ligands that form highly stable complexes in the minor groove of DNA. Although specific pairing rules within the 2:1 motif can be used to distinguish the four Watson. Crick base pairs, a comparable recognition code for 1:1 polyamide:DNA complexes had not been descri...
