Abstract
Thiophenol (PhSH), a highly reactive aromatic thiol, plays an essential role as a common industrial raw material in food, pesticides, pharmaceuticals, and cosmetics. In this work, we designed and constructed two fluorescent probes CM-PhSH and CM-Ratio-PhSH by a rational strategy. Specifically, coumarin fluorophores with excellent optical properties were modified, and olefinic unsaturated bonds served as reaction sites for the detection of PhSH. Based on this, the introduction of the nitro group at specific positions of the CM-PhSH changed the fluorescence emission of the CM-Ratio-PhSH, eventually obtaining a novel ratiometric fluorescent probe CM-Ratio-PhSH for PhSH detection. Surprisingly, these two probes exhibited advantages such as high specificity and low limit of detection (LOD) for CM-PhSH 32.3 nM and CM-Ratio-PhSH 40.2 nM, respectively. Furthermore, subsequent experiments demonstrated CM-PhSH and CM-Ratio-PhSH could be successfully used for highly selective and rapid detection of PhSH in aqueous solutions, live cells, and complex food samples.

Abstract
Thiophenol (PhSH) is widely used in industry, however, it is extremely harmful to the environment and human health due to its high toxicity. In this work, we developed a new FRET-ICT-based ratiometric fluorescent and colorimetric probe (DMNP) for detecting PhSH. DMNP had an ultrahigh energy transfer efficiency (99.7%) and clear spacing of two emission peaks (133 nm). DMNP achieved a fast response to PhSH and exhibited drastic enhancement (over 2100 folds) of the fluorescence intensity ratio upon addition of PhSH. DMNP showed good linear response in the PhSH concentration ranges of 0.5-13 μM and 17.0-22.0 μM. Meanwhile, DMNP could also be applied to monitor PhSH in a variety of real water samples.

Abstract
Abstract
Background
The increase in resistance of pathogenic organisms to the available chemotherapeutic agents are critical challenges in drug design and development, motivating researchers to look for novel compounds that can combat multidrug-resistant organisms. Recently, chalcones have been proved to be attractive moieties in drug discovery.
Results
Eight novel triphenylamine chalcones with different substitution patterns were successfully synthesized via the conventional Claisen–Schmidt condensation reaction in an alkaline medium at room temperature, and recrystallized using ethanol, the percentage yield of the compounds were between 30 and 92%. The structures of the synthesized chalcones were successfully characterized and confirmed using FT-IR, NMR spectroscopic and GC–MS spectrometric techniques.
Conclusions
The results of the biological studies showed that all the synthesized chalcones possess remarkable activities against the tested microbes, by showing a significant zone of inhibitions relative to that of the standard drugs used. The investigation revealed that 1b showed highest ZOI (30 mm), lowest MIC (12.5 µg/ml) and MBC/MFC (50 µg/ml) on Aspergillus niger. Therefore, displayed better antifungal potential as compared to the rest of the compounds, and can be a potential antifungal drug candidate.

Abstract
BACKGROUND Poly (ADP-ribose) polymerase (PARP) plays a key role in DNA damage repair. A novel compound (E)-N'-(2,3-dibromo-4,5-dihydroxyphenyl)-N-(phenylcarbamothioyl)formimidamide (DDPF-20) with excellent PARP inhibitory activity was synthesized. OBJECTIVE In this study, we aimed to clarify the mechanism of the novel PARP inhibitor DDPF-20 against lung cancer by inducing DNA damage and inhibiting angiogenesis. METHOD The cytotoxic effect of DDPF-20 on A549 cell line was determined with an MTT assay. Cell cycle and apoptosis was determined by flow cytometer. The γH2AX foci was detected by immunofluorescence. Capillary-like tube formation assay and chick chorioallantoic membrane (CAM) assay was used to detect angiogenesis inhibitory effect of DDPF-20. The expressions of related proteins were detected by western blot. The anticancer activity of DDPF-20 in vivo was also detected. RESULTS With an IC50 value of 52.42 ± 15.13 nM, DDPF-20 inhibited the proliferation, induced G2/M cycle arrest and induced apoptosis of human lung cancer A549 cells. Further research showed that DDPF-20 induced DNA double-strand breaks (DSBs). Interestingly, DDPF-20 inhibited the tube formation of HUVEC cells, as well as inhibited the neovascularization of CAM, proving the angiogenesis inhibitory ability of DDPF-20. Mechanism studies proved that DDPF-20 inhibited the PI3K/Akt/VEGF signaling pathway. In an in vivo study, DDPF-20 inhibited tumor growth of an A549 xenograft. Analysis of the molecular mechanism underlying this effect revealed that the PI3K/Akt/VEGF pathway was involved in DDPF-20-induced cell death and inhibited angiogenesis in vivo. CONCLUSION This study suggested that the novel PARP inhibitor DDPF-20 may have therapeutic potential in treating lung cancer.

Abstract
Thiophenol and hydrosulphite are a group of toxic environmental pollutants, which contaminate land, water and food exhibiting a serious risk to human health. Herein, we reported a xanthene dye-based sensor (DSF) with dual well-known response sites for visual detecting PhSH and HSO3-. Specifically, when DSF reacted with PhSH firstly, the color of the solution changed to blue with bright red fluorescence emission. After added with HSO3-, the color of the solution became yellow, and emitted yellow fluorescence signal. However, DSF was first added with HSO3-, the color of the solution changed to purple with no-fluorescence emission, and then PhSH was added, the color of the solution changed to yellow with a bright yellow fluorescence. Notably, DSF exhibited high sensitivity and selectivity for PhSH and HSO3- detection with a very low detection limits of 2.27 nM and 22.91 nM, respectively. More importantly, DSF could detect PhSH and HSO3- in water, real-food and biological systems. Therefore, the experimental results showed DSF as a robust new logical monitoring tool for the detection of PhSH and HSO3- in water, real-food samples and biological systems.

Photophysical Study and Biological Applications of Synthetic Chalcone-Based Fluorescent Dyes. Molecules 2021; 26:molecules26102979.

Abstract
A chalcone series (3a–f) with electron push–pull effect was synthesized via a one-pot Claisen–Schmidt reaction with a simple purification step. The compounds exhibited strong emission, peaking around 512–567 nm with mega-stokes shift (∆λ = 93–139 nm) in polar solvents (DMSO, MeOH, and PBS) and showed good photo-stability. Therefore, 3a–f were applied in cellular imaging. After 3 h of incubation, green fluorescence was clearly brighter in cancer cells (HepG2) compared to normal cells (HEK-293), suggesting preferential accumulation in cancer cells. Moreover, all compounds exhibited higher cytotoxicity within 24 h toward cancer cells (IC50 values ranging from 45 to 100 μM) than normal cells (IC50 value >100 μM). Furthermore, the antimicrobial properties of chalcones 3a–f were investigated. Interestingly, 3a–f exhibited antibacterial activities against Escherichia coli and Staphylococcus aureus, with minimum bactericidal concentrations (MBC) of 0.10–0.60 mg/mL (375–1000 µM), suggesting their potential antibacterial activity against both Gram-negative and Gram-positive bacteria. Thus, this series of chalcone-derived fluorescent dyes with facile synthesis shows great potential for the development of antibiotics and cancer cell staining agents.

The sensing of various analytes including metal ions and anions is at an incredible speed due to their widespread use in biological processes. Various small molecular species have been reported for the detection of various analytes, with the advantage of low cost and high sensitivity. Among various classes of organic molecules, chalcones are suitable candidates for the design of new chemosensors for targeted ions. In this review, using extensive examples of chalcone-based chemosensors, we explore the design, mechanism, and performance of various chemosensors for the detection of different ions. We believe that this review will provide new insight for researchers in related areas to develop chemosensors for various targeted ions.
