Abstract
This paper reports on the modification of two synthetic steps in the usual protocol used for obtaining EMICORON. EMICORON is a benzo[ghi]perylen-diimide, which was synthesized for the first time in our laboratory in 2012, and has shown to have in vivo antitumor activities that interferes with the tumor growth and development using a multi-target mechanism of action. The provided modifications, which involved the reaction times, the reaction conditions, and the work-up procedures, allowed the global yield of the process to be increased from 28% to about 40%. Thus, this new procedure may be more suitable for recovering higher amounts of EMICORON to be used in further preclinical studies.

Abstract
Most drugs are small molecules because of their attractive pharmacokinetics, manageable development and manufacturing, and effective binding into the concave crevices of bio-macromolecules. Despite these features, they often fall short when it comes to effectively recognizing the surfaces of bio-macromolecules. One way to overcome the challenge of biomolecular surface recognition is to develop small molecules that become self-assembled ligands (SALs) prior to binding. Herein, we report SALs made from 8-aryl-2'-deoxyguanosine derivatives forming precise hydrophilic supramolecular G-quadruplexes (SGQs) with excellent size, shape, and charge complementarity to G-quadruplex DNA (QDNA). We show that only those compounds forming SGQs act as SALs, which in turn differentially stabilize QDNAs from selected oncogene promoters and the human telomeric regions. Fluorescence resonance energy-transfer melting assays are consistent with spectroscopic, calorimetric, and light scattering studies, showing the formation of a "sandwichlike" complex QDNA·SGQ·QDNA. These results open the door for the advent of SALs that recognize QDNAs and potentially the surfaces of other bio-macromolecules such as proteins.

Abstract
The interaction of the porphyrin derivative H2TCPPSpm4, having spermine pendants in the four meso positions, with the G-quadruplex (GQ) structure formed by the DNA aptamer TGGGAG has been investigated by means of UV, electronic circular dichroism and PAGE studies. The results reported here demonstrate that the porphyrin derivative is capable of stabilizing or destabilizing the higher-ordered structures of parallel GQs, depending on the method used to reach their relative stoichiometry (titration vs. single addition). Noteworthily, when two equivalents of H2TCPPSpm4 were mixed directly with one equivalent of the (TGGGAG)4 GQ to reach a 2 : 1 H2TCPPSpm4 : GQ ratio T1/2 higher than 80 °C was also observed confirming the presence of higher-ordered GQ structures.

Abstract
It is well known that G-quadruplexes are targets of great interest for their roles in crucial biological processes, such as aging and cancer. Hence, a promising strategy for anticancer drug therapy is the stabilization of these structures by small molecules. We report a high-throughput in silico screening of commercial libraries from several different vendors by means of a combined structure-based pharmacophore model approach followed by docking simulations. The compounds selected by the virtual screening procedure were then tested for their ability to interact with human telomeric G-quadruplex folding by circular dichroism, fluorescence spectroscopy, and fluorescence intercalator displacement. Our approach resulted in the identification of a 13-[(dimethylamino)methyl]-12-hydroxy-8H-benzo[c]indolo[3,2,1-ij][1,5]naphthyridin-8-one derivative as a novel promising stabilizer of G-quadruplex structures within the human telomeric and the c-myc promoter sequences.

Abstract
G-quadruplex-based drug delivery carriers (GDDCs) were designed to capture and release a telomerase inhibitor in response to a target mRNA. Hybridization between a loop on the GDDC structure and the mRNA should cause the G-quadruplex structure of the GDDC to unfold and release the bound inhibitor, anionic copper(II) phthalocyanine (CuAPC). As a proof of concept, GDDCs were designed with a 10-30-mer loop, which can hybridize with a target sequence in epidermal growth factor receptor (EGFR) mRNA. Structural analysis using circular dichroism (CD) spectroscopy showed that the GDDCs form a (3 + 1) type G-quadruplex structure in 100 mM KCl and 10 mM MgCl2 in the absence of the target RNA. Visible absorbance titration experiments showed that the GDDCs bind to CuAPC with Ka values of 1.5 × 105 to 5.9 × 105 M−1 (Kd values of 6.7 to 1.7 μM) at 25 °C, depending on the loop length. Fluorescence titration further showed that the G-quadruplex structure unfolds upon binding to the target RNA with Ka values above 1.0 × 108 M−1 (Kd values below 0.01 μM) at 25 °C. These results suggest the carrier can sense and bind to the target RNA, which should result in release of the bound drug. Finally, visible absorbance titration experiments demonstrated that the GDDC release CuAPC in response to the target RNA.

Abstract
Several ligands can bind to the non-canonical G-quadruplex DNA structures thereby stabilizing them. These molecules can act as effective anticancer agents by stabilizing the telomeric regions of DNA or by regulating oncogene expression. In order to better interact with the quartets of G-quadruplex structures, G-binders are generally characterized by a large aromatic core involved in π-π stacking. Some natural flexible cyclic molecules from Traditional Chinese Medicine have shown high binding affinity with G-quadruplex, such as berbamine and many other alkaloids. Using the structural information available on G-quadruplex structures, we performed a high throughput in silico screening of commercially available alkaloid derivative databases by means of a structure-based approach based on docking and molecular dynamics simulations against the human telomeric sequence d[AG3(T2AG3)3] and the c-myc promoter structure. We identified 69 best hits reporting an improved theoretical binding affinity with respect to the active set. Among them, a berberine derivative, already known to remarkably inhibit telomerase activity, was related to a better theoretical affinity versusc-myc.

Abstract
The redox mechanism of two trisubstituted triazole-linked phenyl derivatives (CL41 and CL42) and a disubstituted triazole-linked phenyl derivative (CL2r50) were studied using cyclic, differential pulse and square wave voltammetry at a glassy carbon electrode. The CL41, CL42 and CL2r50 oxidation is a complex, pH-dependent irreversible process involving the formation of electroactive products that undergo two consecutive reversible oxidation reactions. The DNA interaction with CL41, CL42 and CL2r50 was investigated by differential pulse voltammetry using the dsDNA-electrochemical biosensor and in DNA/trisubstituted triazole incubated solutions. All three trisubstituted triazole-linked phenyl derivatives interacted with dsDNA causing morphological and oxidative damage to the dsDNA structure in a time-dependent manner. The DNA-electrochemical biosensor enabled the detection of oxidative damage to DNA following the occurrence of the 8-oxoGua and/or 2,8-oxoAde oxidation peaks.

Abstract
INTRODUCTION G-quadruplexes (G4s) are targets of great interest because of their roles in crucial biological processes, such as aging and cancer. G4s are based on the formation of G-quartets, stabilised by Hoogsteen-type hydrogen bonds and by interaction with cations between the tetrads. These biologically relevant conformations were first discovered in eukaryotic chromosomal telomeric DNA, but have also been found in the proximal location of promoters in a number of human genes. Therefore, the extensive analysis of an intriguing target could move towards the rational drug design of new selective anticancer agents. AREAS COVERED The authors review G4 structural characterisation, with detailed insight related to the polymorphism issue. The authors describe the topologically distinct G4 structural forms and the factors involved in their interconversion mechanisms, such as the sequence of the oligonucleotides, the strand stoichiometry and orientation, the syn-anti conformation of the guanine glycosidic bonds and the G4 loop types and the environmental factors. Furthermore, the authors report several studies related to folding and unfolding kinetic profiles in order to understand the conformational view of monomolecular G4 formations. EXPERT OPINION G4 unimolecular nucleic acids can be considered as valid targets for the rational drug development of novel anticancer agents. Structural biology represents an essential link between the biology and medicinal chemistry knowledge in this field. In silico methods have already been demonstrated to be useful, especially if well integrated with biophysical tests. If this proves successful, the G4-targeting paradigm could also be extended to drug discovery beyond neoplastic pathologies.

Abstract
The sequence d(GGGCGGGGAGGGGGAAGGGA) occurs in the promoter region of the B-raf gene. An X-ray crystallographic study has found that this forms an unprecedented dimeric quadruplex arrangement, with a core of seven consecutive G-quartets and an uninterrupted run of six potassium ions in the central channel of the quadruplex. Analogy with previously reported promoter quadruplexes had initially suggested that in common with these a monomeric quadruplex was to be expected. The structure has a distorted G·C·G·C base quartet at one end and four flipped-out adenosine nucleosides at the other. The only loops in the structure are formed by the cytosine and by the three adenosines within the sequence, with all of the guanosines participating in G-quartet formation. Solution UV and circular dichroism data are in accord with a stable quadruple arrangement being formed. 1D NMR data, together with gel electrophoresis measurements, are consistent with a dimer being the dominant species in potassium solution. A single-chain intramolecular quadruplex has been straightforwardly constructed using molecular modeling, by means of a six-nucleotide sequence joining 3' and 5' ends of each strand in the dimer. A human genomic database search has revealed a number of sequences containing eight or more consecutive short G-tracts, suggesting that such intramolecular quadruplexes could be formed within the human genome.

Abstract
Following previous studies on anthraquinone and acridine-based G-quadruplex ligands, here we present a study of similar aromatic cores, with the specific aim of increasing G-quadruplex binding and selectivity with respect to duplex DNA. Synthesized compounds include two and three-side chain xanthone and xanthene derivatives, as well as a dimeric “bridged” form. ESI and FRET measurements suggest that all the studied molecules are good G-quadruplex ligands, both at telomeres and on G-quadruplex forming sequences of oncogene promoters. The dimeric compound and the three-side chain xanthone derivative have been shown to represent the best compounds emerging from the different series of ligands presented here, having also high selectivity for G-quadruplex structures with respect to duplex DNA. Molecular modeling simulations are in broad agreement with the experimental data.

Abstract
Tetra-substituted naphthalene diimide (ND) derivatives with positively charged termini are potent stabilizers of human telomeric and gene promoter DNA quadruplexes and inhibit the growth of human cancer cells in vitro and in vivo. The present study reports the enhancement of the pharmacological properties of earlier ND compounds using structure-based design. Crystal structures of three complexes with human telomeric intramolecular quadruplexes demonstrate that two of the four strongly basic N-methyl-piperazine groups can be replaced by less basic morpholine groups with no loss of intermolecular interactions in the grooves of the quadruplex. The new compounds retain high affinity to human telomeric quadruplex DNA but are 10-fold more potent against the MIA PaCa-2 pancreatic cancer cell line, with IC50 values of ~10 nM. The lead compound induces cellular senescence but does not inhibit telomerase activity at the nanomolar dosage levels required for inhibition of cellular proliferation. Gene array qPCR analysis of MIA PaCa-2 cells treated with the lead compound revealed significant dose-dependent modulation of a distinct subset of genes, including strong induction of DNA damage responsive genes CDKN1A, DDIT3, GADD45A/G, and PPM1D, and repression of genes involved in telomere maintenance, including hPOT1 and PARP1.

Abstract
Based on previous work on both perylene and coronene derivatives as G-quadruplex binders, a novel chimeric compound was designed: N,N'-bis[2-(1-piperidino)-ethyl]-1-(1-piperidinyl)-6-[2-(1-piperidino)-ethyl]-benzo[ghi]perylene-3,4:9,10-tetracarboxylic diimide (EMICORON), having one piperidinyl group bound to the perylene bay area (positions 1, 12 and 6, 7 of the aromatic core), sufficient to guarantee good selectivity, and an extended aromatic core able to increase the stacking interactions with the terminal tetrad of the G-quadruplex. The obtained "chimera" molecule, EMICORON, rapidly triggers extensive DNA damage of telomeres, associated with the delocalization of telomeric protein protection of telomeres 1 (POT1), and efficiently limits the growth of both telomerase-positive and -negative tumor cells. Notably, the biological effects of EMICORON are more potent than those of the previously described perylene derivative (PPL3C), and more interestingly, EMICORON appears to be detrimental to transformed and tumor cells, while normal fibroblasts expressing telomerase remain unaffected. These results identify a new promising G-quadruplex ligand, structurally and biologically similar on one side to coronene and on the other side to a bay-monosubstituted perylene, that warrants further studies.

Abstract
Ligand-induced stabilization of the G-quadruplex DNA structure derived from the single-stranded 3'-overhang of the telomeric DNA is an attractive strategy for the inhibition of the telomerase activity. The agents that can induce/stabilize a DNA sequence into a G-quadruplex structure are therefore potential anticancer drugs. Herein we present the first report of the interactions of two novel bisbenzimidazoles (TBBz1 and TBBz2) based on Tröger's base skeleton with the G-quadruplex DNA (G4DNA). These Tröger's base molecules stabilize the G4DNA derived from a human telomeric sequence. Evidence of their strong interaction with the G4DNA has been obtained from CD spectroscopy, thermal denaturation, and UV-vis titration studies. These ligands also possess significantly higher affinity toward the G4DNA over the duplex DNA. The above results obtained are in excellent agreement with the biological activity, measured in vitro using a modified TRAP assay. Furthermore, the ligands are selectively more cytotoxic toward the cancerous cells than the corresponding noncancerous cells. Computational studies suggested that the adaptive scaffold might allow these ligands to occupy not only the G-quartet planes but also the grooves of the G4DNA.

Abstract
Telomeric DNA and C-myc22 are DNA G-quadruplex (G4)-forming sequences associated with tumorigenesis. Ligands that can facilitate the formation and increase the stabilization of G4 can halt tumor cell proliferation and have been regarded as potential anti-cancer drugs. In the present study, we have investigated the interaction of 11 natural alkaloids with G4 formed by telomeric DNA and C-myc22 sequences. Our results indicated that sanguinarine (San), palmatine (Pal), and berberine (Beb) of the first series (S1) can induce the formation of G4 as well as increase the stabilization ability. Daurisoline (S2-1), O-methyldauricine (S2-2), O-diacetyldaurisoline (S2-3), daurinoline (S2-4), dauricinoline (S2-5), N,N'-dimethyldauricine iodide (S2-6), and N,N'-dimethyldaurisoline iodide (S2-7) of the second series (S2) showed similar stabilization ability. We found that unsaturated ring C, N(+) positively charged centers, and conjugated aromatic rings are key factors to increase the stabilization ability of S1, and we gave some advice on structure modification to S2 through structure-activity study. Besides, we found San and Pal to be cell cycle blocker in G(1). San was speculated to bind to G4 through intercalation or end stacking.

Abstract
Perylene bisimides are among the most valuable functional dyes and have numerous potential applications. As a result of their chemical robustness, photostability, and outstanding optical and electronic properties, these dyes have been applied as pigments, fluorescence sensors, and n-semiconductors in organic electronics and photovoltaics. Moreover, the extended quadrupolar π system of this class of dyes has facilitated the construction of numerous supramolecular architectures with fascinating photophysical properties. However, the supramolecular approach to the formation of perylene bisimide aggregates has been restricted mostly to organic media. Pleasingly, considerable progress has been made in the last few years in developing water-soluble perylene bisimides and their application in aqueous media. This Review provides an up-to-date overview on the self-assembly of perylene bisimides through π-π interactions in aqueous media. Synthetic strategies for the preparation of water-soluble perylene bisimides and the influence of water on the π-π stacking of perylene bisimides as well as the resulting applications are discussed.

Abstract
The burgeoning knowledge about the structure of telomeres and the roles of various factors involved in telomere maintenance provides several possible targets for pharmacological intervention. To date the area that has received major attention regarding drug discovery is the targeting the telomeric G-quadruplex (G4) structure. G4 ligands were initially designed to counteract telomerase action at telomeres. Surprisingly, their antiproliferative effects can occur in telomerase negative cells and follow kinetics, which cannot be merely explained by telomere shortening, suggesting that these compounds affect other pathways, not necessarily related to telomere biology. Impressively, it has been shown that polyaromatic compounds featuring end-stacking binding properties trigger a strong DNA damage response at telomeres. This is typical of the telomere deprotection occurring during cellular senescence or upon telomere injury. It emerged that the G4-interacting agents are more than simple telomerase inhibitors and that their direct target is rather telomere than telomerase. This review summarizes the most valid experimental approaches for studying the pharmacological telomere damage induced by G4-ligand complexes.

Abstract
Thirteen compounds with diverse chemical structures have been identified as selective telomeric G-quadruplex-binding ligands through screening the NCI Diversity Set II, the NCI Natural Products Set II and the NCI Mechanistic Diversity Set libraries containing a total of 2307 members against a human telomeric G-quadruplex using a FRET-based DNA melting assay. These compounds show significant selectivity towards a telomeric G-quadruplex compared to duplex DNA, fall within a molecular weight range of 327-533, and are generally consistent with the Lipinski Rule of Five for drug-likeness. Thus they provide new chemical scaffolds for the development of novel classes of G-quadruplex-targeting agents.

Abstract
G-quadruplex (G4) is a characteristic secondary structure of nucleic acids containing repetitive tandem guanines. G4-forming sequences are found prevalent in the human genome by bioinformatics analysis. Accumulating evidence has suggested that G4s are involved in many biological processes. Selective isolation of G4s would be an effective tool in the study of G4s. In this paper, we prepared four affinity matrixes using hemin or a perylene derivative (N,N'-Bis-(2-(amino)ethyl)-3,4,9,10-perylenetetracarboxylic acid diimide, Pery01) as ligand, and investigated the retention behaviors of different G4s on these matrixes. Our experimental results suggest that the π-π stacking interaction between ligand and G-tetrad plays a key role in the selective isolation of G4s, whereas the electrostatic interaction between DNA and matrix causes the nonspecific binding. One matrix prepared by immobilizing Pery01 on polyglycidylmethacrylate (PGMA) beads through an aminocaproic acid spacer exhibits good selectivity for parallel structure G4s and has been successfully used to directly isolate a spiked parallel G4 from plasma.

Abstract
G-quadruplexes are special secondary structures formed from G-rich sequences of DNA, and have proven to play important roles in a number of biological systems, including the regulation of gene transcription and translation. The highly distinctive nature of G-quadruplex structures and their functions suggest that G-quadruplexes can act as novel targets for drug development. As a highly sensitive analytical tool, mass spectrometry has been widely used for the analysis of G-quadruplex structures. Electrospray-ionization mass spectrometry, in particular, has found captivating applications to probe interactions between small molecules and G-quadruplex DNA. In this review, we will discuss: (1) mass spectrometry probing of the formation, binding affinity, and stoichiometry between G-quadruplexes and small molecules; (2) stabilization and collision-dissociation behavior of G-quadruplex DNA; (3) the exploration of the equilibrium transfer between a G-quadruplex and duplex DNA; and (4) the ESI-MS analysis of the conversion of intramolecular and intermolecular G-quadruplexes. Finally, we will also introduce the application of new techniques in the analysis of G-quadruplex conformation, such as ion-mobility and infrared multiphoton-dissociation mass spectrometry. We believe that, with the new technical developments, mass spectrometry will play an unparalleled role in the analysis of the G-quadruplex structures.

Abstract
Previous studies indicate that some perylene bisimide derivatives can drive the assembly of DNA G-quadruplexes, thus suggesting the possible advantage in the adoption of perylene-conjugated G-rich oligonucleotides in biological and biotechnological applications. Nevertheless, the typical poor solubility of perylene bisimides strongly limits the number of suitable chemical strategies to prepare perylene-conjugated oligonucleotides. In order to overcome these difficulties, we employed the earlier described core twisted perylene derivatives possessing unique optical and electronic properties, besides good solubility in common solvents. As a first result, the large-scale synthesis of a new dibromoperylene derivative (PEOEBr) phosphoramidite building block is herein reported. Furthermore, the structural behavior of the conjugated PEOEBr-GGGTTAGGG (HTRp2) human telomeric repeat was investigated by using CD, UV, fluorescence, and gel electrophoresis techniques in desalted water and in K(+)- and Na(+)-containing buffers. We observed that the peculiar property of PEOEBr moieties to form dimers instead of extended aggregates drives the HTRp2 strands toward dimerization and mainly promotes the formation of quadruplex species having both the 5'-ends located at the same side of the structures. However, the counterions present in solutions (K(+) or Na(+)) as well as the strand concentration, also contribute to influence the topology and the stoichiometry of formed structures. Furthermore, unlike the unmodified sequence GGGTTAGGG (HTR2), HTRp2 strands quickly associate into G-quadruplexes even in desalted water, as assessed by CD experiments.
