Abstract
This article includes a thorough examination of the inhibitory potential of quinoline-based drugs on cancer cells, as well as an explanation of their modes of action. Quinoline derivatives, due to their various chemical structures and biological activity, have emerged as interesting candidates in the search for new anticancer drugs. The review paper delves into the numerous effects of quinoline-based chemicals in cancer progression, including apoptosis induction, cell cycle modification, and interference with tumor-growth signaling pathways. Mechanistic insights on quinoline derivative interactions with biological targets enlightens their therapeutic potential. However, obstacles such as poor bioavailability, possible off-target effects, and resistance mechanisms make it difficult to get these molecules from benchside to bedside. Addressing these difficulties might be critical for realizing the full therapeutic potential of quinoline-based drugs in cancer treatment.

Abstract
Organic small molecules that can recognize and bind to G-quadruplex and i-Motif nucleic acids have great potential as selective drugs or as tools in drug target discovery programs, or even in the development of nanodevices for medical diagnosis. Hundreds of quadruplex-interactive small molecules have been reported, and the challenges in their design vary with the intended application. Herein, we survey the major achievements on the therapeutic potential of such quadruplex ligands, their mode of binding, effects upon interaction with quadruplexes, and consider the opportunities and challenges for their exploitation in drug discovery.

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
Selective and sensitive detection of G-quadruplex DNA structures is an important issue and attracts extensive interest. To this end, numerous small molecular fluorescent probes have been designed. Here, we present a series of N-alkylated styrylquinolinium dyes named Ls-1, Ls-2 and Ls-3 with varying side groups at the chain end. We found that these dyes exhibited different binding behaviors to DNAs, and Ls-2 with a sulfonato group at the chain end displayed sensitivity and selectivity to G-quadruplex DNA structures in vitro. The characteristics of this dye and its interaction with G-quadruplex DNA were comprehensively investigated by means of UV-vis spectrophotometry, fluorescence, circular dichroism and molecular docking. Furthermore, confocal fluorescence images and MTT assays indicated dye Ls-2 could pass through membrane and enter the living HepG2 cells with low cytotoxicity.

Abstract
G-quadruplex DNAs are highly prevalent in the human genome and involved in many important biological processes. However, many aspects of their biological mechanism and significance still need to be elucidated. Therefore, the development of fluorescent probes for G-quadruplex detection is important for the basic research. We report here on the development of small molecular dyes designed on the basis of carbazole scaffold by introducing styrene-like substituents at its 9-position, for the purpose of G-quadruplex recognition. Results revealed that the side group on the carbazole scaffold was very important for their ability to selectively recognize G-quadruplex DNA structures. 1a with the pyridine side group displayed excellent fluorescence signal turn-on property for the specific discrimination of G-quadruplex DNAs against other nucleic acids. The characteristics of 1a were further investigated with UV-vis spectrophotometry, fluorescence, circular dichroism, FID assay and molecular docking to validate the selectivity, sensitivity and detailed binding mode toward G-quadruplex DNAs.

Abstract
Guanine-rich nucleic acid sequences able to form four-stranded structures (G-quadruplexes, G4) play key cellular regulatory roles and are considered as promising drug targets for anticancer therapy. On the basis of the organization of their structural elements, G4 ligands can be divided into three major families: one, fused heteroaromatic polycyclic systems; two, macrocycles; three, modular aromatic compounds. The design of modular G4 ligands emerged as the answer to achieve not only more drug-like compounds but also more selective ligands by targeting the diversity of the G4 loops and grooves. The rationale behind the design of a very comprehensive set of ligands, with particular focus on the structural features required for binding to G4, is discussed and combined with the corresponding biochemical/biological data to highlight key structure-G4 interaction relationships. Analysis of the data suggests that the shape of the ligand is the major factor behind the G4 stabilizing effect of the ligands. The information here critically reviewed will certainly contribute to the development of new and better G4 ligands with application either as therapeutics or probes.

Abstract
A series of 2-arylethenyl-N-methylquinolinium derivatives were designed and synthesized based on our previous research of 2-arylethenylquinoline analogues as multifunctional agents for the treatment of Alzheimer's disease (AD) (Eur. J. Med. Chem. 2015, 89, 349-361). The results of in vitro biological activity evaluation, including β-amyloid (Aβ) aggregation inhibition, cholinesterase inhibition, and antioxidant activity, showed that introduction of N-methyl in quinoline ring significantly improved the anti-AD potential of compounds. The optimal compound, compound a12, dramatically attenuated the cell death of glutamate-induced HT22 cells by preventing the generation of ROS and increasing the level of GSH. Most importantly, intragastric administration of a12•HAc was well tolerated at doses up to 2000 mg/kg and could traverse blood-brain barrier.

Abstract
Up-regulation of a disintegrin and metalloproteinase 10 (ADAM10) to prevent the formation of β-amyloid (Aβ) peptides might be a promising strategy to treat Alzheimer's disease (AD). RNA G-quadruplex motif within the 5'-UTR of the ADAM10 mRNA is an inhibitory element for ADAM10 translation. Thus, mitigation of the suppressive effect of this motif using an RNA G-quadruplex-forming G-rich sequence (QGRS) binder might be a new approach for AD therapy. Herein, a series of new methylquinolinium derivatives were synthesized and screened by surface plasmon resonance (SPR) and the dual-luciferase reporter assay. Among them, compound 24 showed selective affinity for the QGRS of ADAM10 and could strongly up-regulate the translation of it. Moreover, treatment with 24 led to a significant increase of the secretion of sAPPα, consequently decreasing the Aβ40 in cellular. These results illustrate that the interaction between the RNA QGRS and a small molecule may be a new molecular strategy to modulate the translation of ADAM10.

Abstract
BACKGROUND Farnesyl pyrophosphate synthase (FPPS) is a key regulatory enzyme in the biosynthesis of cholesterol and in the post-translational modification of signaling proteins. It has been reported that non-bisphosphonate FPPS inhibitors targeting its allosteric binding pocket are potentially important for the development of promising anti-cancer drugs. METHODS The following methods were used: organic syntheses of non-bisphosphonate quinoline derivatives, enzyme inhibition studies, fluorescence titration assays, synergistic effect studies of quinoline derivatives with zoledronate, ITC studies for the binding of FPPS with quinoline derivatives, NMR-based HAP binding assays, molecular modeling studies, fluorescence imaging assay and MTT assays. RESULTS We report our syntheses of a series of quinoline derivatives as new FPPS inhibitors possibly targeting the allosteric site of the enzyme. Compound 6b showed potent inhibition to FPPS without significant hydroxyapatite binding affinity. The compound showed synergistic inhibitory effect with active-site inhibitor zoledronate. ITC experiment confirmed the good binding effect of compound 6b to FPPS, and further indicated the binding ratio of 1:1. Molecular modeling studies showed that 6b could possibly bind to the allosteric binding pocket of the enzyme. The fluorescence microscopy indicated that these compounds could get into cancer cells. CONCLUSIONS Our results showed that quinoline derivative 6b could become a new lead compound for further optimization for cancer treatment. GENERAL SIGNIFICANCE The traditional FPPS active-site inhibitors bisphosphonates show poor membrane permeability to tumor cells, due to their strong polarity. The development of new non-bisphosphonate FPPS inhibitors with good cell membrane permeability is potentially important.
