Shedding light on the interaction of polydatin and resveratrol with G-quadruplex and duplex DNA: a biophysical, computational and biological approach. Int J Biol Macromol 2019; 151:1163-1172. [PMID: 31747572 DOI: 10.1016/j.ijbiomac.2019.10.160] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 10/09/2019] [Accepted: 10/18/2019] [Indexed: 12/17/2022]
Abstract
Among polyphenols, trans-resveratrol (tRES) and trans-polydatin (tPD) exert multiple biological effects, particularly antioxidant and antiproliferative. In this work, we have investigated the interaction of tPD with three cancer-related DNA sequences able to form G-quadruplex (G4) structures, as well as with a model duplex, and compared its behaviour with tRES. Interestingly, fluorescence analysis evidenced the ability of tPD to bind all the studied DNA systems, similarly to tRES, with tRES displaying a higher ability to discriminate G4 over duplex with respect to tPD. However, neither tRES nor tPD produced significant conformational changes of the analyzed DNA upon binding, as determined by CD-titration analysis. Computational analysis and biological data confirmed the biophysical results: indeed, molecular docking evidenced the stronger interaction of tRES with the promoter of c-myc oncogene, and immunoblotting assays revealed a reduction of c-myc expression, more effective for tRES than tPD. Furthermore, in vitro assays on melanoma cells proved that tPD was able to significantly reduce telomerase activity, and inhibit cell proliferation, with tRES producing higher effects than tPD.

Abstract
RATIONALE As a key signal transducer and transcription activator, STAT3 plays a very important role in many cell processes. We found that there were many G-rich sequences existing in the STAT3 gene including its promoter, intron, exon and 3'-flanking regions. These G-rich tracts can form G-quadruplexes under near physiological conditions. In this research, we systemically studied the G-quadruplexes in the STAT3 gene at a whole gene scale for the first time. METHODS In this research, the formation of G-quadruplexes in the STAT3 gene was probed by electrospray ionization mass spectrometry (ESI-MS) and circular dichroism (CD). Their structures were constructed and refined by a molecular modeling method. We also used ESI-MS to study the recognition of the G-quadruplexes in the promoter of the STAT3 gene by flexible molecules which do not have a planar core like the other common quadruplex ligands. RESULTS The results based on ESI-MS suggested that the G-quadruplexes in the promoter of the STAT3 gene formed and were further recognized by some small molecules. CONCLUSION Our research proved that the G-rich sequences in the STAT3 gene could form G-quadruplexes under near physiological conditions. This provides a promising target to study the regulation of cell signal transduction in vivo and drug design that aims to target STAT3 G-quadruplexes. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
A novel copper(II) complex with mixed ligands including β-[(3-formyl-5-methyl-2-hydroxy-benzylidene)amino]propionic acid anion and 1,10'-phenanthroline was synthesized, and its crystal structure was thoroughly characterized. It exerted excellent inducing apoptosis, anti-angiogenesis and antiproliferative properties in vitro. The complex can bind human serum albumin (HSA) at physiological pH conditions. Remarkably, it can induce formation of the mixed parallel/antiparallel G-quadruplex structures in the G-rich sequence of the proximal vascular endothelial growth factor (VEGF) promoter, and stabilize these G-quadruplex structures, which provide an opportunity for anti-angiogenesis chemotherapeutics. Furthermore, the complex showed a strong uptake, and exhibited multiple anticancer functions by inhibiting the expression of p-Akt and p-Erk1/2 proteins and by upregulating the levels of reactive oxygen species (ROS). Because of the reported results, this new copper(II) complex qualifies itself as a potential anticancer drug candidate.

Abstract
CONTEXT Polydatin, also named piceid (3,4',5-trihydroxystilbene-3-β-d-glucoside, PD), is a monocrystalline compound isolated from Polygonum cuspidatum Sieb. et Zucc. (Polygonaceae), but is also detected in grape, peanut, hop cones, red wines, hop pellets, cocoa-containing products, chocolate products and many daily diets. There are numerous investigations reported of PD in the past 22 years, but they are usually scattered across various publications, which may block further research and clinical use of PD. OBJECTIVE The article summarizes and evaluates the published scientific information of PD pharmacological effects and pharmacokinetics since 1990. MATERIALS AND METHODS The information from 98 cases included in this review was compiled using major databases such as MEDLINE, Elsevier, Springer, PubMed, Scholar and CNKI. RESULTS Numerous pharmacological investigations of PD mainly focus on cardiovascular effects, neuroprotection, anti-inflammatory and immunoregulatory effects, anti-oxidation, anti-tumor, liver and lung protection, etc. CONCLUSION A great number of pharmacological and pharmacokinetic investigations in the past 22 years have demonstrated that PD has favorable therapeutic properties, indicating its potential as an effective material. However, further research is needed to explore its molecular mechanisms of action and definitive target proteins.

Abstract
In this study, electrospray ionization mass spectrometry (ESI-MS) was used to investigate the binding interaction of six alkaloids with parallel intermolecular G-quadruplex [d(TGGGGT)](4), and five alkaloids including berberine, jatrorrhizine, palmatine, tetrandrine, and fangchinoline showed complexation with the target DNA. Relative binding affinities were estimated on the basis of mass spectrometric data. The slight differences in chemical structures of berberine, jatrorrhizine, and palmatine had little influence on their binding affinities to [d(TGGGGT)](4). Tetrandrine and fangchinoline selectively bound to [d(TGGGGT)](4) versus duplex DNA. Collision-induced dissociation (CID) experiments showed that the complexes with berberine, jatrorrhizine, and palmatine dissociated via strand separation and ligand retaining in the strand while the complexes with tetrandrine and fangchinoline were dissociated via ligand elimination. A comparison of dissociation patterns in CID experiments of complexes with the alkaloids to those with the traditional G-quadruplex DNA binders suggested an end-stacking binding mode for tetrandrine and fangchinoline and an intercalation binding mode for berberine, jatrorrhizine, and palmatine to the target DNA. The current work not only provides deep insight into alkaloid/[d(TGGGGT)](4) complexes and useful guidelines for design of efficient anticancer agents but also demonstrates the utility of ESI-MS as a powerful tool for evaluating interaction between ligand and quadruplex DNA.

Abstract
In this study, electrospray ionization mass spectrometry (ESI-MS) and circular dichroism (CD) spectroscopy were used to investigate selective recognition of G-quadruplex in the vascular endothelial growth factor (VEGF) gene with 12 small-molecule natural products. We found that kaempferol, a natural flavonol, shows the highest binding affinity among the 12 natural molecules. The results from ESI-MS and CD spectra indicated that kaempferol could enhance the thermal stability of the VEGF–G-quadruplex and showed selective recognition for the G-quadruplex in a solution consisting of the G-quadruplex and the corresponding duplex DNA.
