Abstract
DNA-binding polyamides are synthetic oligomers of pyrrole/imidazole units with high specificity and affinity for double-stranded DNA. To increase their synthetic diversity, we report a mild methodology based on 4-methyltrityl (Mtt) solid phase peptide synthesis (SPPS), whose building blocks are more accessible than the standard Fmoc and Boc SPPS ones. We demonstrate the robustness of the approach by preparing and studying a hairpin with all precursors. Importantly, our strategy is orthogonal and compatible with sensitive molecules and could be readily automated.

Abstract
Pyrrole-imidazole polyamides (Py-Im polyamides) are cell-permeable compounds that bind to the minor groove of double-stranded DNA in a sequence-specific manner without causing denaturation of the DNA. These compounds can be used to control gene expression and to stain specific sequences in cells. Here, we review the history, structural variations, and functional investigations of Py-Im polyamides.

Abstract
Two advances in the synthesis of hairpin pyrrole-imidazole polyamides (PAs) are described. First, the application of a convergent synthetic strategy is shown, involving the Boc-based solid phase synthesis of a C-terminal fragment and the solution phase synthesis of the N-terminal fragment. Second a new hybrid resin is developed that allows for the preparation of hairpin PAs lacking a C-terminal β-alanine tail. Both methods are compatible with a range of coupling reagents and provide a facile, modular route to prepare PA libraries in high yield and crude purity.

Abstract
This review analyses the literature concerning non-fluorescent and fluorescent probes for nucleic acid imaging in fixed and living cells from the point of view of their suitability for imaging intracellular native RNA and DNA. Attention is mainly paid to fluorescent probes for fluorescence microscopy imaging. Requirements for the target-binding part and the fluorophore making up the probe are formulated. In the case of native double-stranded DNA, structure-specific and sequence-specific probes are discussed. Among the latest, three classes of dsDNA-targeting molecules are described: (i) sequence-specific peptides and proteins; (ii) triplex-forming oligonucleotides and (iii) polyamide oligo(N-methylpyrrole/N-methylimidazole) minor groove binders. Polyamides seem to be the most promising targeting agents for fluorescent probe design, however, some technical problems remain to be solved, such as the relatively low sequence specificity and the high background fluorescence inside the cells. Several examples of fluorescent probe applications for DNA imaging in fixed and living cells are cited. In the case of intracellular RNA, only modified oligonucleotides can provide such sequence-specific imaging. Several approaches for designing fluorescent probes are considered: linear fluorescent probes based on modified oligonucleotide analogs, molecular beacons, binary fluorescent probes and template-directed reactions with fluorescence probe formation, FRET donor-acceptor pairs, pyrene excimers, aptamers and others. The suitability of all these methods for living cell applications is discussed.

Abstract
Aberrant gene expression is responsible for a myriad of human diseases from infectious diseases to cancer. Precise regulation of these genes via specific interactions with the DNA double helix could pave the way for novel therapeutics. Pyrrole-imidazole polyamides are small molecules capable of binding to pre-determined DNA sequences up to 16 base pairs with affinity and specificity comparable to natural transcription factors. In the three decades since their development, great strides have been made relating to synthetic accessibility and improved sequence specificity and binding affinity. This perspective presents a brief history of early seminal developments in the field and highlights recent reports of the utility of polyamides as both genetic modulators and molecular probes.

Abstract
Fluorophores that are conjugated with N-methylpyrrole-N-methylimidazole (Py-Im) polyamides postulates versatile applications in biological and physicochemical studies. Here, we show the design and synthesis of new types of pyrene-conjugated hairpin Py-Im polyamides (1-5). We evaluated the steady state fluorescence of the synthesized conjugates (1-5) in the presence and absence of oligodeoxynucleotides 5'-CGTATGGACTCGG-3' (ODN 1) and 5'-CCGAGTCCATACG-3' (ODN 2) and observed a distinct increase in emission at 386nm with conjugates 4 and 5. Notably, conjugate 5 that contains a β-alanine linker had a stronger binding affinity (K(D)=1.73×10(-8)M) than that of conjugate 4 (K(D)=1.74×10(-6)M). Our data suggests that Py-Im polyamides containing pyrene fluorophore with a β-alanine linker at the γ-turn NH(2) position can be developed as the competent fluorescent DNA-binding probes.

Abstract
Recently, the versatility of N-methylpyrrole (Py)-N-methylimidazole (Im) polyamide conjugates, which have been developed from the DNA-binding antibiotics distamycin A and netropsin, has been shown. These synthetic small molecules can permeate cells to bind with duplex DNA in a sequence-specific manner, and hence can influence gene expression in vivo. Accordingly, several reports demonstrating the sequence specificity and biological activity of Py-Im polyamides have accumulated. However, the benefits of Py-Im polyamides, in particular those conjugated with fluorophores, has been overlooked. Moreover, clear directions for the employment of these attractive artificial small molecules have not yet been shown. Here, we present a detailed overview of the current and prospective applications of Py-Im polyamide-fluorophore conjugates, including sequence-specific recognition with fluorescence emission properties, and their potential roles in biological imaging.

Abstract

Microwave synthesis was utilized to rapidly build Py-Im polyamides in high yields and purity using Boc-protection chemistry on Kaiser oxime resin. A representative polyamide targeting the 5′-WGWWCW-3′ (W = A or T) subset of the consensus Androgen and Glucocorticoid Response Elements was synthesized in 56% yield after 20 linear steps and HPLC purification. It was confirmed by Mosher amide derivatization of the polyamide that a chiral α-amino acid does not racemize after several additional coupling steps.

Abstract
Methods for sequence-specific detection in double-stranded DNA (dsDNA) are becoming increasingly useful and important as diagnostic and imaging tools. Recently, we designed and synthesized pyrrole (Py)-imidazole (Im) polyamides possessing two pyrene moieties, 1, which showed an increased excimer emission in the presence of (CAG)(12)-containing oligodeoxynucleotides (ODN) 1 and 2. In this study, we synthesized bis-pyrenyl Py-Im polyamides with rigid linkers 2, 3, and 4 to improve their fluorescence properties. Among the conjugates, 2 showed a marked increase in excimer emission, which was dependent on the concentration of the target ODN and the number of CAG repeats in the dsDNA. Unlike conjugate 1, which has flexible linkers, the excimer emission intensity of 2 was retained at over 85%, even after 4h. Py-Im polyamides have the potential to be important diagnostic molecules for detecting genetic differences between individuals.
