Combination drug therapy has become an effective strategy for chronic metabolic disease, especially cardiovascular disease. In the present study, possible drug combinations were screened and the mechanism of the combinations against cardiac hypertrophy was examined within 1,8-cineole, β -caryophyllene, linalool, and β -pinene.H9c2 cells were treatment with 1,8-cineole, β -caryophyllene, linalool, and β -pinene individually or in combination for 24 h after isoprenaline stimulation. Cell viability was detected by the MTT assay. Subsequently, bioinformatic analysis and network pharmacology were used to reveal the multi-targeted synergistic therapeutic effect of the combination treatment compounds on cardiac hypertrophy. Ultimately, western blot and elisa was performed to analyses the protein expression in vivo . MTT results found that 1,8-cineole and β -caryophyllene synergistically increased cell viability with CalcuSyn software analyses. Specifically, bioinformatic and network pharmacology analysis showed PTGS2, TNF, IL-6, AKT1, NOS2, and CAT were identified as the key targets. P13K-AKT signaling pathway was involved in the reversal of cardiac hypertrophy by the combination of 1,8-cineole and β -caryophyllene. The in vitro results indicated that the combination synergistically treated the isoprenaline-induced mice against structural and functional myocardial damage via the P13K-AKT signaling pathway. Collectively, the combined application of 1,8-cineole and β -caryophyllene synergistically reverses cardiac hypertrophy in isoprenaline-induced H9c2 cells and mice.

Abstract In this study, a novel series of 7-azaindole-1,2,3-triazole bearing N -benzamide derivatives 3a – 3r were synthesized and fully characterized by 1 H NMR, 13 C NMR, and MS. The prepared compounds were tested against A549 and HepG2 cell lines by using MTT assay in vitro anticancer activity. Compounds 3d , 3l , 3q , and 3r exhibited the most promising, with IC 50 (7.83, 7.58, 9.47, and 8.65 μM, respectively) against A549 compared with Gefitinib (IC 50 , 6.77 μM) and IC 50 (6.98, 6.69, 10.18, and 7.97 μM, respectively) against HepG2 compared with Sorafenib (IC 50 , 5.65 μM). Further molecular docking studies showed that compounds 3d , 3l , 3q , and 3r can bind well to protein targets 3LXY, 4AGD, and 3WZE, so these compounds have the potential to be developed into multi-targeted kinase inhibitor.

To better treat gastric diseases and lower systemic side effect, it is essential to design new vectors to control drug release in stomach. Aiming to this challenge, we developed a new gastroretentive drug delivery system : nanomicelles-loaded gastroretentive beads. Firstly, the chitosan-coated emodin-loaded nanomicelles were developed and characterized. In vitro cytotoxicity of emodin-loaded nanomicelles, emodin suspensions and blank nanomicelles was evaluated with human gastric carcinoma SGC-7901 cells by MTT , indicating that the blank nanomicelles had null cytotoxicity and emodin-loaded nanomicelles had better antitumor efficacy compared with emodin suspensions. Secondly, nanomicelles-loaded floating mucoadhesive beads (NFM-Beads) were prepared, and the swelling, degradation, mucoadhesion and floating ability in vitro were separately investigated. FT-IR spectroscopy was applied to identify the formation of nanomicelles and NFM-Beads. Emodin release from NFM-Beads in vitro was fitted to anomalous transport mechanism. In vivo gastroretention behavior of NFM-Beads was evaluated by BaSO 4 -based X-ray imaging exams, showing that NFM-Beads can be retained in rabbit stomach for at least 8 h. Overall, the new NFM-Beads system could be an effective approach to improve the therapeutic potency of drug against gastric cancer.

In order to develop new natural product-based anticancer agents, a series of 1,3,4-oxadiazole analogues based on petiolide A were prepared and evaluated for their anticancer activities by MTT method. The structures of all analogues were characterized by various spectral analyses, and B9 was further confirmed by X-ray crystallography. Among all the synthesized compounds, B1 displayed the most promising growth inhibitory effect on colon cancer cells (HCT116) with the IC 50 value of 8.53 μM. Flow cytometric analysis exhibited that B1 arrested the cell cycle at G2 phase and induced apoptosis. Additionally, network pharmacology analysis calculated that B1 might target several key proteins, including AKT serine/threonine kinase 1 (AKT1), SRC proto-oncogene, non-receptor tyrosine kinase (SRC) and epidermal growth factor receptor (EGFR). Furthermore, molecular docking study indicated that B1 had potentially high binding affinity to these three target proteins. Given these results, analogue B1 could be deeply developed as potential anticancer agents.

To better understand the toxicological activities of perfluorooctanoic acid (PFOA), we examined the effects of PFOA on apoptosis and its molecular mechanism in SMMC-7721 hepatoma cells. Cell viability was evaluated by MTT assay and apoptosis was determined by flow cytometry. Western blot and quantitative real-time PCR were used to examine the protein and gene expressions of Bax and Bcl-2. Our results showed that PFOA inhibited SMMC-7721 cell growth and induced apoptosis. PFOA treatment increased Bax expression and increased Bcl-2 expression at both gene and protein levels. Our study demonstrated that PFOA had toxic effects on SMMC-7721 cells, such as inhibiting cell proliferation and inducing apoptosis. Furthermore, we showed that PFOA-mediated induction of apoptosis involved inducing Bax and decreasing Bcl-2 expression as a molecular mechanism of its toxicological effects.

Cell viability detection plays a crucial role in apoptosis and anticancer drug research. Compared with conventional colorimetric assays and organic fluorescent probe-based imaging, it is greatly desired to develop a simple and facile fluorescent probe for in situ real-time detection of cell viability. Herein, MoS2 nanoflakes are employed as fluorescent probes for detecting cancer cell viability by using their inherent tunable photoluminescence (PL) properties by ion intercalation. The appropriate amount of MoS2 nanoflakes for A549 lung cancer cells was firstly determined by MTT assay. After MoS2 nanoflakes successfully covered cells, the effects of the nanoflakes on cell morphology and mechanical properties were studied by atomic force microscopy (AFM). Then, the modulation of PL by potassium ions (K+) from cells was investigated at different cell viabilities. The results showed that PL intensity increased as cell viability decreased. Finally, the nanoflakes were further used as fluorescent probes to assess the cell viability change induced by anticancer drugs. The results showed that with the increase of drug concentration, the fluorescence intensity increased, indicating a decrease in cell viability. The ion-modulated PL of MoS2 nanoflakes makes MoS2 a promising candidate for applications in anticancer drug screening.

In this study, we will report on the synthesis and application of efficient botanical agrochemicals from turpentine for sustainable crop protection. Two series of turpentine derived secondary amines were synthesized and identified by FT-IR, 1H NMR, 13C NMR, and HRMS. The herbicidal activities against Echinochloa crus-galli were evaluated. The potential toxicity of the synthesized compounds was tested by MTT cytotoxicity analysis. The effect of structure of the synthesized secondary amines and corresponding Schiff base compounds on their activities was investigated by quantitative structure–activity relationship (QSAR) study. All target products were found to be low toxicity, with similar or higher herbicidal activities than commercial herbicides diuron and Glyphosate. Results of QSAR study showed that a best four-descriptor QSAR model with R2 of 0.880 and Rloo2 of 0.818 was obtained. The four descriptors most relevant to the herbicidal activities are the min valency of a N atom, the max total interaction for a C−H bond, the relative number of aromatic bonds, and the min partial charge (Qmin).

Nitrogen and phosphorus co-doped carbon dots (NPCDs) were synthesized by a microwave method, using citric acid monohydrate and diammonium hydrogen phosphate as raw materials. The morphology, structures and elemental compositions of NPCDs were characterized by transmission electron microscopy, X-ray diffractometry, and X-ray photoelectron spectroscopy. It was found that NPCDs show good selectivity to Hg2+ over other metal ions. And the fluorescence of the NPCDs-Hg2+ system can be recovered in the presence of glutathione (GSH). As such, a “turn-off-on” fluorescence probe can be constructed for the detection of Hg2+ and GSH. Under the optimum working conditions, the linear response of NPCDs to Hg2+ was in the range 0.10–30 μM with a detection limit of 9.9 nM. The linear range of GSH was 0.50–32 μM with a limit of detection of 11.2 nM. The proposed method has been successfully applied to the detection of Hg2+ and GSH in various biological samples. What is more, NPCDs have low cytotoxicity verified by the MTT assay. Using NPCDs as a probe, fluorescence images were obtained for HepG2 cells, which indicated that it could monitor the levels of Hg2+ and GSH in biological systems.

Selaginella doederleiniiHieron has been traditionally used as a folk antitumor herbal medicine in China. In this paper, the phytochemical components of the total biflavonoids extract fromS. doederleiniiwere studied by using high-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry (HPLC-ESI-QTOF MS/MS) in negative ion mode, and their in vitro and in vivo anticancer effects were evaluated. Four types of biflavonoids fromS. doederleinii, including IC3′–IIC8′′, IC3′–IIC6′′, IC3′–IIC3′′′, and C–O linked biflavonoids were examined originally using QTOF MS/MS. The fragmentation behavior of IC3′–IIC3′′′ linked biflavonoids was reported for the first time. A total of twenty biflavonoids were identified or tentatively characterized and eight biflavonoids were found fromS. doederleiniifor the first time. Furthermore, the 3-(4,5-Dimethyl-2-thizolyl)-2,5-diphenyltertazolium bromide (MTT) assay and xenograft model of mouse lewis lung cancer(LLC) in male C57BL/6 mice revealed favorable anticancer properties of the total biflavonoids extracts fromS. doederleinii. The results of this work could provide useful knowledge for the identification of biflavonoids in herbal samples and further insights into the chemopreventive function of this plant.Keywords:Selaginella doederleinii;HPLC-ESI-QTOF MS/MS;biflavonoids;murine B16 melanoma cell;mouse lewis lung cancer (LLC) cell;LLC mouse model

The aim of the present study was to investigate the cytotoxic effects and underlying molecular mechanisms of nitidine chloride (NC) in hepatocellular carcinoma cells via quantitative proteomics. MTT assays were used to detect the inhibitory effects of NC in Bel-7402 liver cancer cells, and the number of apoptotic cells was measured by flow cytometry. Quantitative proteomics technology based on iTRAQ was used to discover differential expressed proteins after NC treatment, and bioinformatic techniques were further used to screen potential targets of NC. Molecular docking was applied to evaluate the docking activity of NC with possible upstream proteins, and their expression was detected at the mRNA and protein levels by quantitative reverse transcription PCR and western blotting. NC inhibited the proliferation of Bel-7402 cells after 24 h of treatment and stimulated apoptosis in vitro. The proteomics experiment showed that NC triggers mitochondrial damage in HCC cells and transcription factor AP-1 (c-Jun) may be a potential target of NC (fold change = 4.36 ± 0.23). Molecular docking results revealed the highest docking score of NC with c-Jun N-terminal kinase (JNK), one of the upstream proteins of c-Jun. Moreover, the mRNA and protein expression of c-Jun and JNK were significantly increased after NC treatment (p

Two new rhein-organotin complexes Ph 3 Sn(O 2 CC 14 H 7 O 4 ) ( RS01 ) and Cy 3 Sn(O 2 CC 14 H 7 O 4 ) ( RS02 ) were synthesized and characterized by elemental analysis, IR, 1 H NMR, 13 C NMR, 119 Sn NMR, X-ray crystallography and thermo-gravimetric analysis. Both complexes has a triclinic crystal system P -1 space group and one-dimensional supramolecular chain structure. The MTT results demonstrated that rhein's anticancer activity was effectively increased by introducing organotin, RS01 and RS02 exhibited excellent anticancer activity in vitro, significantly superior to cisplatin and mitoxantrone. Interestingly, despite the fact that RS01 and mitoxantrone share the same 9,10-anthraquinone scaffold structure, RS01 not only showed high anticancer activity but also much lower nephrotoxicity than mitoxantrone. Flow cytometry showed that RS01 could significantly induce cell apoptosis and arrest cell cycle in G2 phase. Molecular docking and UV–Vis absorption spectra suggested that RS01 may be intercalation with DNA. Furthermore, western blot results showed that RS01 activated the DNA damage critical protein γ -H 2 AX and regulated the expression level of the mitochondrial apoptotic pathway critical protein (Bax/Bcl-2). Thus, RS01 induced cell death may be mediated through DNA damage and mitochondrial pathways. As a result, RS01 has significant development and application potential as an anticancer agent.

Drug delivery carriers hold tremendous promise for improving cancer treatment, and polyrotaxane (PR) has shown excellent drug-carrying properties. However, there have been some reports that, when used as a drug carrier, water-soluble PR is not easily labeled with organic fluorescent dyes. Herein, we synthesized a drug-loaded fluorescent porphyrin-terminated PR (PR-COOH) which can be used as a tracer material in drug and gene delivery. The structure, morphology and zeta potential of PR-COOH were characterized by nuclear magnetic resonance, high-resolution transmission electron microscopy and zeta potentiometry. In this research, cisplatin (CDDP) is used as a model drug. The zeta potential, drug encapsulation efficiency and drug release of CDDP-loaded PR (PR-COOH-Pt) were studied. Confocal laser scanning microscopy showed that PR-COOH could be internalized by HeLa and CT26 cells. The antitumor efficacy of PR-COOH-Pt was investigated in vitro by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and in vivo by a xenograft tumor model. The results showed that PR-COOH-Pt could significantly inhibit tumor growth; thus PR-COOH-Pt has a promising role in cancer therapy.
