Herein, an organocatalytic method for photochemical C-O bond cleavage of lignin systems is reported. The use of photochemistry enabled fragmentation of the ss-O-4 linkage, the primary linkage in lignin, provides the fragmentation products in good to high yields. The approach was merged with reported oxidation conditions in a one-pot, two-step platform without any intermediary purification, suggesting its high fidelity. The future utility of the organocatalytic method was illustrated by applying the visible light-mediated protocol to continuous flow processing.

With the aim of expanding the scope of SAR on piperlongumine (PL), a naturally occurring anticancer molecule, we have designed a novel hybrid molecule bearing 3,4-dihydroisoquinolin-1(2H)-one and trans-cinnamic acids. The structure, based on hybridization strategy, is used for hybridization of naturally occurring scaffolds. We have synthesized 14 hybrid molecules by coupling 3,4-dihydroisoquinolin-1(2H)-one core with cinnamic acids using the mix anhydride approach. The newly synthesized inhibitors were evaluated for cell viability against breast cancer MCF-7 and cervical cancer HeLa cell lines. Furthermore, the active compounds were screened for their potential in breast cancer MDA-MB-231, cervical cancer C33A cell lines, prostate cancer DU-145, PC-3, and normal VERO cells. From the series, compound 10g was seen to inhibit MCF-7 cell growth significantly with GI(50) < 0.1 mu M along with growth inhibition in MDA-MB-231 (GI(50) = 20 mu M) and C33A (GI(50) = 3.2 mu M). While the inhibitor 10i inhibits MCF-7 breast cancer cell growth GI(50) = 3.42 mu M along with inhibition of cell growth in MDA-MB-231 (GI(50) = 30 mu M), HeLa (GI(50) = 7.67 mu M), C33A (GI(50) = 13 mu M), DU-145 (GI(50) = 6.45 mu M), PC-3 (GI(50) = 8.68 mu M), and VERO (GI(50) = 2.93 mu M), respectively. Furthermore, molecular docking study demonstrated these compounds could bind tightly to the colchicine domain of tubulin through a network of favorable steric and electrostatic interactions and thus act as a tubulin polymerization inhibitor.

Approximately 60% of human cancers exhibit enhanced activity of ERK1 and ERK2, reflecting their multiple roles in tumor initiation and progression. Acquired drug resistance, especially mechanisms associated with the reactivation of the MAPK (RAF/MEK/ERK) pathway represent a major challenge to current treatments of melanoma and several other cancers. Recently, targeting ERK has evolved as a potentially attractive strategy to overcome this resistance. Herein, we report the design and synthesis of novel series of fused naphthofuro[3,2-c] quinoline-6,7,12-triones 3a-f and pyrano[3,2-c]quinoline-6,7,8,13-tetraones 5a,b and 6, as potential ERK inhibitors. New inhibitors were synthesized and identified by different spectroscopic techniques and X-ray crystallography. They were evaluated for their ability to inhibit ERK1/2 in an in vitro radioactive kinase assay. 3b and 6 inhibited ERK1 with IC50s of 0.5 and 0.19 mu M, and inhibited ERK2 with IC50s of 0.6 and 0.16 mu M respectively. Kinetic mechanism studies revealed that the inhibitors are ATP-competitive inhibitors where 6 inhibited ERK2 with a K-i of 0.09 mu M. Six of the new inhibitors were tested for their in vitro anticancer activity against the NCI-60 panel of tumor cell lines. Compound 3b and 6 were the most potent against most of the human tumor cell lines tested. Moreover, 3b and 6 inhibited the proliferation of the BRAF mutant A375 melanoma cells with IC50s of 3.7 and 0.13 mu M, respectively. In addition, they suppressed anchorage-dependent colony formation. Treatment of the A375 cell line with 3b and 6 inhibited the phosphorylation of ERK substrates p-90RSK and ELK-1 and induced apoptosis in a dose dependent manner. Finally, a molecular docking study showed the potential binding mode of 3b and 6 within the ATP catalytic binding site of ERK2.

In current work, a class of novel 4,5-dihydro-1H-pyrazole-1-carboxylate derivatives (E01-E28) were designed, synthesized and evaluated. Among them, the most potent compound E24 exhibited comparable activity against a panel of cancer cells (GI(50) ranging 0.05-0.98 mu M) and tubulin polymerization inhibition (IC50 = 1.49 mu M) with reference drug CA-4(P) (GI(50) ranging 0.019-0.32 mu M, IC50 = 2.18 mu M). The following assays indicated that compound E24 disturbed the dynamics of tubulin catastrophe and rescue, which triggered G2/M arrest, leading to ROS accumulation, cleavage of PARP and apoptosis. Molecular dynamics simulation validated that compound E24 could tightly bind into tubulin heterodimers with beta Lys 254 and beta Cys 241 of tubulin in the docking pose. Metabolic stability and pharmacokinetics parameters were also determined. The half time (t(1/2)) displayed species differences in three microsomes. The plasma elimination half-life (t(1/2)), peak plasma concentration (C-max), mean retention time (MRT), the area under the curve (AUC(0-infinity),) and distribution volume (V-z) of E24 after intravenous administration were 0.90 +/- 0.22 h, 594.50 +/- 97.23 ng/mL, 1.09 +/- 0.22 h, 413.67 +/- 105.64 ng/mL*h and 5.03 +/- 1.82 L/kg, respectively. In HeLa-xenografts, compound E24 exhibited obvious antitumor efficacy via the suppression of tumor growth without weight loss of body or organ. In brief, compound E24 might be a hopeful candidate with excellent properties for oncotherapy as tubulin polymerization inhibitor. (C) 2018 Elsevier Masson SAS. All rights reserved.

Agarwood is known to have a sedative effect and the less studied volatile aromatic constituents it contains may have contribution to the activity. In this study, two Kyara grade (highest-grade agarwood in Japan) samples were extracted using headspace-solid phase microextraction (HS-SPME) and analyzed through gas chromatography-mass spectrometry (GC-MS). Six low molecular weight aromatic compounds (LACs) and one structurally simple compound (diethylene glycol monoethyl ether) present in the aromas were individually evaluated for inhalational sedative activity in mice through open field test. Doses of 0.0001 g/L to 1 g/L were prepared for each compound and administered to mice (n = 6/dose/compound). Results revealed all compounds decreased spontaneous motor activity at almost all doses. Strongest sedative activity of each compound reduced total spontaneous motor activity by more than half against control, demonstrating their contribution to agarwood aroma and potential as independent sedating agents. Mixtures of compounds using their most effective dose were made and evaluated again for inhalational sedative effect. Interestingly, the combination of all compounds showed no significant effect and even caused stimulation in mice movements. This result suggests antagonistic-like interaction between the compounds, which is probably due to structural similarities. Consequently, it implies the other constituents present in agarwood, along with LACs, are also important to the overall sedative activity.

The synthesis of nitrogen- and oxygen-containing heterocycles has found many applications in the preparation of biomedical intermediates, yet actual synthetic procedures display limitations such as high-loading catalysts, harsh reaction conditions and tedious preparation of heterogeneous catalysts. Alternatively, photocatalysis allows to access functional products with minimum synthetic procedures and waste generation. Here, we present an efficient, simple, green protocol for the synthesis of N- and O-containing six-membered-ring compounds under mild conditions under visible blue light. Various aldehydes and 1,3-diketones can be reacted to afford eight series of corresponding 1,4-dihydropyridines and 4H-benzo[b]pyrans. This protocol has some merits such as the use of abundant and sustainable aqueous ethanol as solvent, short reaction time (within 60 min), no need of catalyst and broad functional group tolerance to afford 81 different series of target molecules in 75-96% yield under mild conditions.

This study investigates the active sites in natural organic matter (NOM) that are important for the removal of Cr (VI), by using Fe3O4 magnetic nanoparticles (MNPs) modified by NOM (Fe3O4@NOM). NaBH4 is used to selectively reduce carbonyl groups in Fe3O4@NOM MNPs to demonstrate the role of carbonyl structures in the reduction of Cr(VI), especially under irradiation. Results observed using NOM and low molecular weight compounds further demonstrated that carbonyl structures in Fe3O4@NOM MNPs, especially aromatic ketones, can strongly promote Cr(VI) reduction. This phenomenon corresponds well to a model in which charge transfer interactions occur between donors and acceptors in NOM.
