Abstract
A series of novel derivatives of isaindigotone, which comes from the root of isaits indinatca Fort, were synthesised (Compound 1-26). Four human gastrointestinal cancer cells (HCT116, PANC-1, SMMC-7721, and AGS) were employed to evaluate the anti-proliferative activity. Among them, Compound 6 displayed the most effective inhibitory activity on AGS cells with an IC50 (50% inhibitory concentration) value of 2.2 μM. The potential mechanism study suggested that Compound 6 induced apoptosis in AGS cells. The collapse of mitochondrial membrane potential (MMP) in AGS cells was proved. In docking analysis, good affinity interaction between Compound 6 and AKT1 was discovered. Treatment of AGS cells with Compound 6 also resulted in significant suppression of PI3K/AKT/mTOR signal pathway. The collapse of MMP and suppression of PI3K/AKT/mTOR signal pathway may be responsible for induction of apoptosis. This derivative Compound 6 could be useful as an underlying anti-tumour agent for treatment of gastric cancer.

Abstract
The combination of heterocycles offers a new opportunity to create novel multicyclic compounds having improved biological activity. Coumarins are ubiquitous natural heterocycle widely adopted in the design of various biologically active compounds. Fusing different heterocycles with coumarin ring is one of the interesting approaches to generating novel hybrid molecules having highlighted biological activities. In the efforts to develop heterocyclic-fused coumarins, a wide range of 3,4-heterocycle-fused coumarins have been introduced bearing outstanding biological activity. The effect of heterocycles annulation at 3,4-positions of coumarin ring on the biological activity of the target structures were discussed. This review focuses on the important progress of 3,4-heterocycle-fused coumarins providing better insight for medicinal chemists on the design and preparation of biologically active heterocycle-fused coumarins with a significant therapeutic effect in the future.

Abstract
(E)-2-[1'-((Diphenylamino)styryl)quinolizinium (3a) and 2,2'-{(phenylimino)-bis[(E)-1'',1'''-styryl]}-bis[quinolizinium] (3b) were synthesized, and their interactions with duplex DNA and quadruplex DNA were investigated with a particular focus on their ability to operate as DNA-sensitive fluorescent probes. Due to the significantly different size and steric demand of these quinolizinium derivatives they exhibit different binding modes. Thus, 3a intercalates into duplex DNA and binds through π stacking to quadruplex DNA, whereas 3b favours groove binding to both DNA forms. The emission intensity of these compounds is very low in aqueous solution, but it increases drastically upon association with duplex DNA by a factor of 11 (3a) and >100 (3b) and with quadruplex DNA by a factor of >100 (3a) and 10 (3b), with emission bands between 600 and 750 nm.

Abstract
The interactions of a triangle-shaped [2.2.2]heptamethinecyanine dye 1, namely 1,5,7-tris-[3-methylbenzothiazol-2-yl]-[2.2.2]heptamethindiium, with quadruplex DNA were studied with photometric and fluorimetric titrations, thermal DNA denaturation, CD and (1)H-NMR spectroscopy. The ligand binds to the quadruplex DNA with moderate affinity (K = 8 × 10(5) M(-1)), mainly by terminal π stacking. Remarkably, the ligand 1 exhibits a selectivity for quadruplex DNA relative to duplex DNA. Whereas the cyanine dye is very weakly fluorescent in aqueous solution, the emission intensity increases by a factor of >100 upon association with quadruplex DNA. Thus, it is shown that trinuclear cyanine derivatives may be employed as selective probes for the fluorimetric detection of quadruplex DNA.

Abstract
We report herein a solvent-free and microwaved-assisted synthesis of several water soluble acyclic pentaheteroaryls containing 1,2,4-oxadiazole moieties (1-7). Their binding interactions with DNA quadruplex structures were thoroughly investigated by FRET melting, fluorescent intercalator displacement assay (G4-FID) and CD spectroscopy. Among the G-quadruplexes considered, attention was focused on telomeric repeats together with the proto-oncogenic c-kit sequences and the c-myc oncogene promoter. Compound 1, and to a lesser extent 2 and 5, preferentially stabilise an antiparallel structure of the telomeric DNA motif, and exhibit an opposite binding behaviour to structurally related polyoxazole (TOxaPy), and do not bind duplex DNA. The efficiency and selectivity of the binding process was remarkably controlled by the structure of the solubilising moieties.

Abstract
Polycyclic azoniahetarenes were employed to determine the effect of the structure of unsubstituted polyaromatic ligands on their quadruplex-DNA binding properties. The interactions of three isomeric diazoniadibenzo[b,k]chrysenes (4 a-c), diazoniapentaphene (5), diazoniaanthra[1,2-a]anthracene (6), and tetraazoniapentapheno[6,7-h]pentaphene (3) with quadruplex DNA were examined by DNA melting studies (FRET melting) and fluorimetric titrations. In general, penta- and hexacyclic azoniahetarenes bind to quadruplex DNA (K(b) ≈10(6) M(-1)) even in the absence of additional functional side chains. The binding modes of 4 a-c and 3 were studied in more detail by ligand displacement experiments, isothermal titration calorimetry, and CD and NMR spectroscopy. All experimental data indicate that terminal π stacking of the diazoniachrysenes to the quadruplex is the major binding mode; however, because of different electron distributions of the π systems of each isomer, these ligands align differently in the binding site to achieve ideal binding interactions. It is proposed that tetraazonia ligand 3 binds to the quadruplex by terminal stacking with a small portion of its π system, whereas a significant part of the bulky ligand most likely points outside the quadruplex structure, and is thus partially placed in the grooves. Notably, 3 and the known tetracationic porphyrin TMPyP4 exhibit almost the same binding properties towards quadruplex DNA, with 3 being more selective for quadruplex than for duplex DNA. Overall, studies on azonia-type hetarenes enable understanding of some parameters that govern the quadruplex-binding properties of parent ligand systems. Since unsubstituted ligands were employed in this study, complementary and cooperative effects of additional substituents, which may interfere with the ligand properties, were eliminated.

Abstract
12-N-Methylated and non-methylated 5,6-dihydrobenzo[c]acridine derivatives were designed and synthesized as new series of c-myc G-quadruplex binding ligands. Their interactions with c-myc G-quadruplex were evaluated using fluorescence resonance energy transfer (FRET) melting assay, circular dichroism (CD) spectroscopy, surface plasmon resonance (SPR), polymerase chain reaction (PCR) stop assay, and molecular modeling. Compared with the non-methylated derivatives, 12-N-methylated derivatives had stronger binding affinity and stabilizing ability to c-myc G-quadruplex structure, and could more effectively stack on the G-quartet surface. All these derivatives had high selectivity for c-myc G-quadruplex DNA over duplex DNA. The reverse transcription (RT) PCR assay showed that compound 21c could down-regulate transcription of c-myc gene in Ramos cell line containing NHE III(1) element, but had no effect in CA46 cell line with NHE III(1) element removed.

Abstract
Some of the most serious diseases are characterized by the presence of a specific secondary structure within DNA or RNA, often in the promoter or the coding region of the responsible gene, that enhances or disrupts expression of the protein. Structural elements that impact cellular function may also be formed in other genomic regions such as telomeres. Compounds that interact with such structural elements may be useful in diagnosis or treatment of patients. In this report, we present a FRET melting assay that allows testing of libraries of compounds against four different nucleic acid structures. Compounds are tested to determine whether they stabilize preformed secondary structures (i.e., whether they cause an increase in melting temperature (T(m))). This property is described by the ΔT(m) parameter, which is the difference between the T(m) of the compound-stabilized structure and the T(m) of the unbound structure. Model oligonucleotides are labeled with FAM as a fluorescent donor and TAMRA as an acceptor. The intensity of FAM fluorescence is recorded as a function of temperature. Melting temperatures are determined by the FRET method in 96-well plates; this assay could easily be converted into 384-well format.
