Identifying cancer-related molecular targets of Nandina domestica Thunb. by network pharmacology-based analysis in combination with chemical profiling and molecular docking studies

Ethnopharmacological relevance: The fruits of Nandina domestica Thunb. have served as folk medicines in Chinese and Japanese tradition for treatment of several tumors including pharynx tumor and tooth abscess for many years, yet its exact mechanism of action is not yet known. Aim of the study: The study targets the identification of the main constituents of the fruits extracts and investigation of their mode of action in cancer therapy via pharmacology-based analysis and molecular docking. Materials and methods: The different extracts of N. domestica Thunb. were analyzed via UPLC?MS/MS for identification of their active constituents. STITCH, DAVID, KEGG and STRING database were utilized for construction of compound-target and compound-target-pathway networks using Cytoscape 3.2.1. Molecular docking analysis of the top hit compounds was performed against the identified top hit molecular targets in the constructed networks. In vitro-testing of Nandina domestica Thunb. against colorectal cancer cell lines was carried out and correlated to the chemical profile of the extract to identify important biomarkers. The ADME properties of the active compounds were also evaluated. Results: 22 compounds were identified by UPLC?MS/MS analysis and were forwarded to network pharmacology-based analysis. Results showed the enrichment of 5 compounds and 4 molecular targets in the network namely; AKT1, CASP3, MAPK1 and TP53. The pathway analysis of the identified targets revealed that 15 cancer-related pathways were enriched including colorectal cancer, endometrial cancer and small-cell lung cancer. In-vitro testing of the extracts against colo-rectal cancer cell lines revealed the fractions enriched in the identified hit compounds were indeed the most active as revealed from the HCA-heat-map. ADME results showed that all compounds were drug-like candidates showing acceptable values according to Lipinski’s rule. Conclusions: Network pharmacology analysis revealed that the compounds isoquercitrin, quercitrin, berberine, chlorogenic acid and caffeic acid showed strong synergistic interactions with the cancer-related targets and pathways. It could be concluded that N. domestica Thunb. constituents affect both apoptosis and Akt-signaling pathways during the stages of early and intermediate adenoma through interaction with the targets CASP3 and MAPK1 (ErC2) while during the stages of late adenoma and carcinoma, the compounds acts through the p53 and ErbB signaling pathways.

Solvent dependent energy transfer of N-bridged naphthalimide- bisindolymaleimide fluorescent dyes

Double build-in chromophores, naphthalimide (NIM) and bisindolymaleimide (BIM), were synthesized and characterized. Absorption and emission properties of double chromophores dye were fully investigated in various solvents. The priority of through bond energy transfer (TBET) to NTM or BIM is solvent dependent. There appears large different emission wavelength change in CHCl 3 and DMF with alkyl attached to BIM. However, the product of cyclohexyl substitution leads to a different emission behavior, which is non-sensitivity to solvent polarity. Quantum chemical calculation for the molecular orbital reveals that intramolecular charge transfer (ICT) is the key factor for their different opto-electronic properties.

Polybenzimidazole (PBI)-functionalized silica nanoparticles modified PBI nanocomposite membranes for proton exchange membranes fuel cells

Polybenzimidazole (PBI) has been chemically bonded to silica nanoparticles (SNPs) through an ozone-mediated process using N-(p-carboxyphenyl)maleimide (pCPM) functionalized SNPs (SNP-pCPM) as precursors, to enhance the interfacial compatibility between SNPs and PBI in PBI/SNP nanocomposites. The PBI-functionalized SNPs (SNP-PBI) have been well characterized and used as inorganic nanofillers for preparation of PBI/SNP-PBI membranes for fuel cells. Addition of PBI-SNP to PBI membranes enhances their thermal and mechanical properties as well as decreases their phosphoric acid uptakes. For the PBI/SNP-PBI membrane with 10wt% of SNP-PBI, it shows a proton conductivity of about 50mScm-1 at 160C, which is 25% higher compared to the pristine PBI membrane. Consequently, the PBI/SNP-PBI membrane demonstrates a maximum power density of 650mWcm-2 in a single cell test, compared to the value of 530mWcm-2 read from the test for pristine PBI membrane.

Characterization of isoquinolin alkaloids from Fumaria agraria and evaluation of their antiproliferative activity against human breast cancer cell lines

Fumaria agraria (Fumariaceae) is an annual plant used traditionally in Algeria for various medicinal purposes. Alkaloids extracts from areal parts were subjected to solvent fractionation and GCMS analysis. Rates of alkaloids recorded were respectively of 700 mg/100 g of Dry Weight of total alkaloids ?TA?, 400 mg/100 g DWof neutral fraction ?NF?, 40 mg/100 g DW of acid fraction ?AF? and 250 mg/100 g DWof the basic fraction ?BF?. Protopine was found to be the most potent alkaloid of the total extract (41.55%). Fractionation showed that Protopine was found essentially in the BF fraction (60.7%). Antiproliferative activities of total alkaloids extract and BF fraction were assessed on MCF-7 and MDAMB- 231 breast cancer and MCF10A mammary normal cell lines, by trypan blue exclusion essay. Both TA extract and BF fraction showed potent antiproliferative activities against MCF-7 breast cancer cells in varying degrees with respective IC50 of 47.8 ¡À 1.8 mug/ml and 17.6 ¡À 0.4 muM, without cell death induction but no impact was observed on normal MCF-10A cell growth. MCF7 Cell line was most sensitive (IC50 of 17,6 ¡À 0,4muM) to BF fraction effect than MDAMB-231 one (IC50 of 36,4 ¡À 0,6muM). Isoquinolein alkaloids of Fumaria agraria and specially the fraction which contain Protopine showed potent antiproliferative activity against breast cancer cells.

Preparation of polybenzoxazine-functionalized Fe3O4 nanoparticles through in situ Diels-Alder polymerization for high performance magnetic polybenzoxazine/Fe3O4 nanocomposites

Hybrids and nanocomposites of polymer and magnetic Fe3O4 nanoparticles have been utilized as magnetically-responsive materials and magnetically-directed nanoparticles. In this work, we prepare polymer-functionalized Fe3O4 nanoparticles through in situ Diels-Alder polymerization using maleimide-functionalized Fe3O4 nanoparticle as a precursor. Polybenzoxazine-functionalized Fe3O4 nanoparticles (MNP-PBz) have been obtained and characterized with Fourier Transform Infrared, X ray photoelectron, and Raman spectroscopies. The high saturation magnetization value of 51.9emu g-1 of the MNP-PBz nanoparticles demonstrates its superparamagnetism. Moreover, MNP-FBz has been utilized as a nanofiller for preparation of cured PBz/MNP-PBz nanocomposites, which contain various MNP-PBz contents of 67, 50, 33, and 17wt.%. The sample of PBz/MNP-PBz-67 shows a storage modulus of 8.0GPa, a saturation magnetization value of 37.6emu g-1, and a glass transition temperature above 380C. As a result, the PBz/MNP-PBz nanocomposites could be classified as magnetically-responsive high performance materials.

Characterization in dual activation by oxaliplatin, a platinum-based chemotherapeutic agent of hyperpolarization-activated cation and electroporation-induced currents

Oxaliplatin (OXAL) is regarded as a platinum-based anti-neoplastic agent. However, its perturbations on membrane ionic currents in neurons and neuroendocrine or endocrine cells are largely unclear, though peripheral neuropathy has been noted during its long-term administration. In this study, we investigated how the presence of OXAL and other related compounds can interact with two types of inward currents; namely, hyperpolarization-activated cation current (Ih) and membrane electroporation-induced current (IMEP). OXAL increased the amplitude or activation rate constant of Ih in a concentration-dependent manner with effective EC50 or KD values of 3.2 or 6.4 muM, respectively, in pituitary GH3 cells. The stimulation by this agent of Ih could be attenuated by subsequent addition of ivabradine, protopine, or dexmedetomidine. Cell exposure to OXAL (3 muM) resulted in an approximately 11 mV rightward shift in Ih activation along the voltage axis with minimal changes in the gating charge of the curve. The exposure to OXAL also effected an elevation in area of the voltage-dependent hysteresis elicited by long-lasting triangular ramp. Additionally, its application resulted in an increase in the amplitude of IMEP elicited by large hyperpolarization in GH3 cells with an EC50 value of 1.3 muM. However, in the continued presence of OXAL, further addition of ivabradine, protopine, or dexmedetomidine always resulted in failure to attenuate the OXAL-induced increase of IMEP amplitude effectively. Averaged current-voltage relation of membrane electroporation-induced current (IMEP) was altered in the presence of OXAL. In pituitary R1220 cells, OXAL-stimulated Ih remained effective. In Rolf B1.T olfactory sensory neurons, this agent was also observed to increase IMEP in a concentration-dependent manner. In light of the findings from this study, OXAL-mediated increases of Ih and IMEP may coincide and then synergistically act to increase the amplitude of inward currents, raising the membrane excitability of electrically excitable cells, if similar in vivo findings occur.
