For the first time, thiamine hydrochloride (VB1) has been employed as a catalyst for the synthesis of chalcones by metal-free Claisen–Schmidt condensation. Such an environmentally benign approach has several advantages such as a wide range of functional groups tolerance, a high yield of products, and the recoverability of this catalyst. Moreover, this unprecedented methodology enables the synthesis of the pharmaceutically important molecule 2′,4′-dihydroxy-6′-methoxy-3′,5′-dimethylchalcone (3f) and its derivatives. Moreover, 3f and its derivatives were screened for their preliminary in vitro neuroprotective activity against oxygen-glucose deprivation/reoxygenation (OGD/R)-induced apoptosis in SH-SY5Y cell lines. Most of the compounds exhibited the neuroprotective activity, and one of the prepared chalcones (3s), which incorporates prenyl moiety, showed the most potency by decreasing the expression of cleaved caspase-3, cleaved caspase-9, Bax, and p53 protein.

Background: A Chinese folk medicine plant Pleurospermum lindleyanum possesses pharmacological activities of heat-clearing, detoxifying and preventing from hepatopathy, coronary heart disease, hypertension, and high altitude sickness. We isolated and characterized its constituents to investigate its synergistic effects against human hepatoma SMMC-7721 cells. Objective: The aim of this study was to explore the synergistic anti-cancer activities of isolates from P. lindleyanum with 5-FU on hepatoma SMMC-7721 cells in vitro and their primary mechanisms. Methods: Sequential chromatographic techniques were conducted for the isolation studies. The isolates structures were established by spectroscopic analysis as well as X-ray crystallographic diffraction. Growth inhibition was detected by MTT assay. The isobologram method was used to assess the effect of drug combinations. Flow cytometry and western blot were used to examine apoptosis and protein expression. Results: A new coumarin (16), along with sixteen known compounds, were isolated from the whole plant of P. lindleyanum and their structures were elucidated by spectroscopic methods. Four coumarins (2, 3, 5, and 16), two flavonoids (8 and 9) and three phytosterols and triterpenes (12-14) were found to synergistically enhance the inhibitory effect of 5-FU against SMMC-7721 cells. Among them, compounds 3 and 16 exhibited the best synergistic effects with IC50 of 5-FU reduced by 16-fold and 22-fold possessing the minimum Combination Index (CI) 0.34 and 0.27. The mechanism of action of combinations might be through synergistic arresting for the cell cycle at G1 phases and the induction of apoptosis. Moreover, western blotting and molecular docking revealed that compounds 3 or 5 might promote 5-FU-induced apoptosis by regulating the expression of Caspase 9 and PARP. Conclusion: Constituents from P. lindleyanum may improve the treatment effectiveness of 5-FU against hepatocellular carcinoma cells.

Abstract Abstract 3842 Poster Board III-778 Background and Rationale Vascular disrupting agents (VDAs) act via selectively disrupting established tumor vasculature and have shown remarkable clinical success as anti-cancer therapies. NPI-2358 is a novel VDA with a distinct structure and mechanism of action from other available VDAs. NPI-2358 binds to the colchicine-binding site of beta-tubulin preventing polymerization and disrupting the cytoplasmic microtubule network, thereby causing loss of vascular endothelial cytoskeletal function, and inducing cytotoxicity in cancer cells. Here, we examined the anti-angiogenic and anti-tumor activity of NPI-2358 in multiple myeloma (MM) cells using both in vitro and in vivo model systems. Material and Methods We utilized MM.1S, MM.1R, RPMI-8226, U266, and INA-6 human MM cell lines, as well as purified tumor cells from MM patients relapsing after prior anti-MM therapies. Cell viability/apoptosis assays were performed using MTT, trypan blue exclusion, and Annexin V/PI staining. Angiogenesis was measured in vitro using Matrigel capillary-like tube structure formation assays: Since human vascular endothelial cells (HUVECs) plated onto Matrigel differentiate and form capillary-like tube structures similar to in vivo neovascularization, this assay measures anti-angiogenic effects of drugs/agents. Migration assays were performed using transwell insert assays. Immunoblot analysis was performed using antibodies to caspase-8, caspase-9, caspase-3, PARP, Bcl-2, Bax, pJNK and GAPDH. Statistical significance was determined using a Student t test. Results Treatment of MM.1S, RPMI-8226, MM.1R, INA-6, and KMS-12BM with NPI-2358 for 24h induces a dose-dependent significant (P < 0.005) decrease in viability of all cell lines (IC50 range: 5-8 nM; n=3). To determine whether NPI-2358-induced decrease in viability is due to apoptosis, MM cell lines were treated with NPI-2358 for 24h; harvested, and analyzed for apoptosis using Annexin V/PI staining. A significant increase in NPI-2358-induced apoptosis was observed in all MM cell lines (% Annexin V+/PI- apoptotic cells: MM.1S, 48 ± 2.3%; MM.1R, 46.6 ± 3.1%; RPMI-8226, 61.7 ± 4.5%; and INA-6, 59.9 ± 3.2%; P < 0.05; n=3). Importantly, NPI-2358 decreased viability of freshly isolated MM cells from patients (IC50 range: 3-7 nM; P < 0.005), without affecting the viability of normal peripheral blood mononuclear cells, suggesting specific anti-MM activity and a favorable therapeutic index for NPI-2358. Examination of in vitro angiogenesis using capillary-like tube structure formation assay showed that even low doses of NPI-2358 (7 nM treatment for 12h; IC50: 20 nM at 24h) significantly decreased tubule formation in HUVECs (70-80% decrease; P < 0.05). Transwell insert assays showed a marked reduction in serum-dependent migration of NPI-2358-treated MM cells (42 ± 2.1% inhibition in NPI-2358-treated vs. control; P < 0.05). NPI-2358 at the concentrations tested (5 nM for 12h) in the migration assays did not affect survival of MM cells (> 95% viable cells). A similar anti-migration activity of NPI-2358 was noted against HUVEC cells (48 ± 1.7% decrease in migration; P < 0.05). Mechanistic studies showed that NPI-2358-induced apoptosis was associated with activation of caspase-8, caspase-9, caspase-3 and PARP. Importantly, treatment of MM.1S cells with NPI-2358 (5 nM) triggered phosphorylation of c-Jun amino-terminal kinase (JNK), a classical stress response protein, without affecting Bcl-2 family members Bax and Bcl-2. Blockade of JNK using dominant negative strategy markedly abrogated NPI-2358-induced apoptosis. Conclusion Our preclinical data provide evidence for remarkable anti-angiogenic and anti-tumor activity of NPI-2358 against MM cells, without significant toxicity in normal cells. Ongoing studies are examining in vivo anti-MM activity of NPI-2358 in animal models. Importantly, a Phase-1 study of NPI-2358 as a single agent in patients with advanced malignancies (lung, prostrate and colon cancer) has already established a favorable pharmacokinetic, pharmacodynamic and safety profile; and, a Phase-2 study of the combination of NPI-2358 and docetaxel in non-small cell lung cancer showed encouraging safety, pharmacokinetic and activity data. These findings, coupled with our preclinical studies, provide the framework for the development of NPI-2358-based novel therapies to improve patient outcome in MM.

Objective To investigate the protective effects of dexmedetomidine (DEX) in oxygen-glucose deprivation/reoxygenation (OGD/R) injury, which is involved in a number of ischaemic diseases. Methods An in vitro OGD/R injury model was generated using mouse Neuro 2A neuroblastoma (N2A) cells. Different concentrations of DEX were administrated to OGD/R cells. CV-65 was used to inhibit p38 microtubule associated protein kinase/extracellular signal-regulated kinases (MAPK/ERK) signalling. Cell proliferation, cell cycle, apoptosis, and the levels of proteins related to p38 MAPK/ERK signalling and apoptosis were evaluated using Cell Counting Kit-8, flow cytometry, TdT-UTP nick end labelling and Western blot analysis, respectively. Results DEX treatment of OGD/R cells promoted cell survival and attenuated OGD/R-induced cell apoptosis. It also activated the p38 MAPK/ERK signalling pathway, increased the levels of Bcl-2, and decreased the levels of Bax and cleaved caspase-3. Treatment with the p38 MAPK/ERK inhibitor CV-65 inhibited the activation of p38 MAPK/ERK and abrogated the DEX-induced effects on cell survival and apoptosis. Conclusions DEX protects N2A cells from OGD/R-induced apoptosis via the activation of the p38 MAPK/ERK signalling pathway. DEX might be an effective agent for the treatment of ischaemic diseases.

Abstract Background Glufosfamide (β-d-glucosylisophosphoramide mustard, GLU) is an alkylating cytotoxic agent in which ifosforamide mustard (IPM) is glycosidically linked to the β-d-glucose molecule. GLU exerted its cytotoxic effect as a targeted chemotherapy. Although, its cytotoxic efficacy in a number of cell lines, there were no experimental or clinical data available on the oncolytic effect of oxazaphosphorine drugs in hepatocellular carcinoma. Therefore, the main objective of the current study is to assess the cytotoxic potential of GLU for the first time in the hepatocellular carcinoma HepG2 cell line model. Methods Cytotoxicity was assayed by the MTT method, and half-maximal inhibitory concentration (IC50) was calculated. Flow cytometric analysis of apoptosis frequencies was measured by using Annexin V/PI double stain, an immunocytochemical assay of caspase-9, visualization of caspase-3, and Bcl2 gene expression were undertaken as apoptotic markers. Mitochondrial membrane potential was measured using the potentiometric dye; JC-1, as a clue for early apoptosis as well as ATP production, was measured by the luciferase-chemiluminescence assay. Results Glufosfamide induced cytotoxicity in HepG2 cells in a concentration- and time-dependent manner. The IC50 values for glufosfamide were significantly lower compared to ifosfamide. The frequency of apoptosis was much higher for glufosfamide than that of ifosfamide. The contents of caspase-9 and caspase-3 were elevated following exposure to GLU more than IFO. The anti-apoptotic Bcl2 gene expression, the mitochondrial membrane potential, and the cellular ATP levels were significantly decreased than in case of ifosfamide. Conclusions The current study reported for the first time cytotoxicity activity of glufosfamide in HepG2 cells in vitro. The obtained results confirmed the higher oncolytic activity of glufosfamide than its aglycone ifosfamide. The generated data warrants further elucidations by in vivo study.

Xylopia aromatica (Lam.) Mart. (Annonaceae) is a typical species from the Brazilian cerrado that presents medicinal properties. The plant is distinguished by its large white flowers which produce a pleasant fragrance. X. aromatica is characterized by a wide range of medicinal application. These characteristics have motivated us to investigate the flowers volatile organic compounds (VOCs) via in vivo and in vitro protocols by a headspace solid-phase microextraction (HS‑SPME) technique combined with gas chromatography-mass spectrometry (HS-SPME/GC‑MS). Four different fibers, extraction times and temperatures were the parameters changed to lead to the maximum profiling of the volatile constituents. Data were analyzed using principal component analysis (PCA). A total of 77 VOCs were extracted from the floral scent, with 52 and 68 extracted from in vivo and in vitro sampling, respectively, of which 48 were reported for the first time in the literature as volatile constituents from X. aromatica flowers. The extraction and identification of VOCs were successfully performed through HS-SPME/GC-MS. The PCA data allowed the identification of parameters that led to the maximum number of VOCs, which were polyacrylate (PA) and carboxen/polydimethylsiloxane (CAR/PDMS) fibers, 60 min extraction time and temperature of 29.0 °C. Among the volatile constituents identified, sesquiterpenes predominated, comprising about 61.04%.

Introduction: Longan is a crop plant of very high economic value, and both its fruit and flower are beneficial for human health. Longan has been increasingly cultivated in Vietnam due to the increasing demand for domestic consumption as well as export of its fruit. However, the widespread emergence and spread of anthracnose, a group of fungal disease affecting a wide range of plant species, in longan has seriously affected both the longan fruit yield and quality in Vietnam. Current methods for the prevention of anthracnose in longan depend mainly on the use of fungicides which are very harmful to human health as well as disruptive to microbial community structures in different ecosystems. In order to obtain an environmentally friendly method of control for this disease, the agent causing anthracnose in longan must first be identified. Therefore, the aim of this study was to isolate and identify the causal anthracnose agent in longan in Vietnam. Methods: Experiments were first carried out with pieces of anthracnose longan leaves pressed onto the surface of potato-dextrose agar (PDA) and incubated for days at 30◦C. Colonies, varying in appearance, were repeatedly isolated and purified on PDA agar, and the anthracnose-causing agent was initially recognized on the basis of colony characteristics and cell morphology. The suspected isolate was then tested for its ability to decompose healthy longan leaf in vitro, and its rDNA region was cloned and sequenced to determine its taxonomy. Antifungal activity testing was performed using the co-culture method. Results: We obtained a fungal isolate with septate hyphae, ovoid appressoria, and conidia (which were cylindrical in shape with rounded ends). This isolate showed a clear ability to decompose healthy longan leaves. At the molecular level, the isolate was determined to be a fungal species belonging to genus Colletotrichum, and therefore named Colletotrichum sp. strain BKHCM. We also found that its growth was inhibited when co-cultured with Streptomyces flaveus, an actinomycete originating from soil. Conclusion: For the first time, we isolated a fungal species belonging to genus Colletotrichum from anthracnose-infected longan leaves in Vietnam. We also showed that the growth of this fungus could potentially be biocontrolled.

This study explored the effects of indole-3-carbinol on the proliferation of human nasopharyngeal carcinoma, both in vitro and in vivo, and the underlying mechanisms in inducing apoptosis of CNE1 cells. Proliferation, apoptosis, malondialdehyde, superoxide dismutase, glutathione peroxidase, expressions of caspase-9, and caspase-3 in human nasopharyngeal carcinoma cells CNE1 were examined. Indole-3-carbinol suppressed proliferation, induced apoptosis, decreased malondialdehyde level, increased the activity of superoxide dismutase and glutathione peroxidase, and up-regulated the expression of active fragments of caspase-9 and caspase-3 both in vitro and in vivo. It was concluded that indole-3-carbinol could inhibit proliferation and induce apoptosis of CNE1 cells and inhibit tumor growth in mice. Increased activity of superoxide dismutase and glutathione peroxidase and activated expression of caspase-9 and caspase-3 were also observed in indole-3-carbinol–treated tumors or tumor cells, suggesting that stress- and apoptosis-related molecules are involved in the indole-3-carbinol–induced apoptosis and inhibition of tumor growth.

Neurodegenerative diseases (NDDs) are chronic conditions that have drawn robust interest from the scientific community. Phytotherapeutic agents are becoming an important source of chemicals for the treatment and management of NDDs. Various secondary metabolites have been isolated from Melicope lunu-ankenda plant leaves, including phenolic acid derivatives. However, their neuroprotective activity remains unclear. Thus, the aim of this study is to elucidate the in vitro neuroprotective activity of 7-geranyloxycinnamic acid isolated from Melicope lunu-ankenda leaves. The neuroprotective activity was evaluated in differentiated human neuroblastoma (SH-SY5Y) cells by monitoring cell viability using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). Moreover, the potential to impair apoptosis in differentiated cells was investigated employing the Annexin V-FITC assay, acridine orange and propidium iodide (AO/PI) staining, and fluorescence microscopy. Morphological assessment and ultrastructural analysis were performed using scanning and transmission electron microscopy to evaluate the effect of 7-geranyloxycinnamic acid on surface morphology and internal features of the differentiated cells. Pre-treatment of neuronal cells with 7-geranyloxycinnamic acid significantly protected the differentiated SH-SY5Y cells against H2O2-induced apoptosis. Cytoskeleton and cytoplasmic inclusion were similarly protected by the 7-geranyloxycinnamic acid treatment. The present findings demonstrate the neuroprotective potential of 7-geranyloxycinnamic acid against H2O2-induced neurotoxicity in neuronal cells, which is an established hallmark of neuronal disorders.
