Traditional cross-coupling reactions show some disadvantages like the use of organohalides or the production of stoichiometric amounts of waste. The dehydrative homo- or heterocoupling of alcohols therefore arises as an interesting approach for a highly atom-economical formation of carbon-carbon bonds, since water is produced as the only by-product. We herein report a simple and direct, metal-free protocol for the synthesis of olefins by applying catalytic amounts of a sulfonic acid and triphenylphosphane under air. A variety of olefins could be synthesized from benzylic alcohols under relatively mild conditions. Additionally, dehydrative hydroarylation of benzylic alcohols with electron-rich arenes was possible by using only Bronsted acid under otherwise same reaction conditions. We could show that phosphane additives are essential to overcome oligomerization as main side reaction by the occupancy of the reactive carbocation intermediate.

Cyperus esculentus tubers are the raw material to prepare tigernut milk (horchata), which can be marketed under Protected Designation of Origin (PDO) C hufa de Valencia. The aim of this study was to characterize commercial tigernut milks and compare PDO and non-PDO products. The following aspects were studied: (i) volatile profile, (ii) descriptive sensory profile, (iii) consumer satisfaction degree. The key volatile compounds were limonene, benzaldehyde, linalool and m-methoxyanisole. Principal component analysis indicated a mix of PDO and nonPDO samples in the groups formed. The highest consumer satisfactions were observed for 2 PDO samples. Penalty analysis showed that 80% of non-PDO samples needed improvements, while this percentage drastically decreased to 40% for PDO samples. The online study proved that a lot of people drink horchata, less people know the PDO Chufa de Valencia and even less people consume the protected product consciously. In conclusion, there was not a clear difference among protected and non-protected tigernut milks respect to volatile compounds but there were differences in the degree of consumer preference. So, it is clear that a lack of knowledge regarding the product and its PDO exists and needs attention.

VEGF/VEGFR-2 signaling plays a critical part in tumor angiogenesis. Inhibition of this pathway has been considered as a promising approach for cancer treatment. In this work, a series of 6,7-dimethoxy-4-anilinoquinazoline derivatives bearing diarylamide moiety were designed, synthesized and evaluated as potent inhibitors of VEGFR-2 kinase. Their in vitro antiproliferation activities against two human cancer cell lines Hep-G2 and MCF-7 have also been determined. Among them, compound 14b exhibited the most potent inhibitory activity against VEGFR-2 with IC50 value of 0.016 +/- 0.002 mu M and it showed the most potent antiproliferative effect against Hep-G2 and MCF-7 with IC50 values at low-micromolar range. Molecular docking studies revealed that these compounds represented by the most potent compound 14b could bind well to the ATP-binding site of VEGFR-2, which suggested that compound 14b could be a potential anticancer agent targeting VEGFR-2.

An electrosynthesis method for amide bond formation has been developed in an attempt to increase the atom economy for this class of reactions. This anion pool method electrochemically generates strong nucleophiles from amine substrates. The amine nucleophiles then react with acid anhydrides to generate amides, and the by- product from this reaction undergoes further chemical transformations to generate pharmaceutically relevant benzoic esters. These one- pot reactions are operationally simple, are performed at room temperature, and avoid rare transition metals and added bases. The amide synthesis is amenable to primary and secondary amines and a variety of anhydrides with yields up to 90% obtained. Atom economy and process mass index ( PMI) values calculated for this procedure indicate that this process can be considered greener compared to traditional amide synthesis routes used by industry. Furthermore, this electrochemical approach showed unique selectivity when substrates that contained two inequivalent amine moieties were examined.

A concise and divergent strategy for the synthesis of the naphterpin and marinone meroterpenoid families has been developed. The approach features a succession of pericyclic reactions-an aromatic Claisen rearrangement, a retro-6 pi-electrocyclization, and two Diels-Alder reactions-which facilitated the first total synthesis of naphterpin itself in five steps from 2,5-dimethoxyphenol, alongside similar syntheses of 7-demethylnaphterpin and debromomarinone. Late-stage oxidation and bromination reactions were also investigated, leading to the first total syntheses of naphterpins B and C and isomarinone.

In this project, nano-MnO2@zeolite-Y (NMOZ) was successfully prepared via hydrothermal technique and its structure was confirmed using FT-IR, XRD, FE-SEM, EDX and BET analyses. MnO2 nanoparticles stabilized on zeolite-NaY were used as nanocatalyst for efficient solventless preparation of 3,4-disubstituted isoxazole-5(4H)-one scaffolds via one-pot three-component reaction of ethyl acetoacetate, hydroxylamine hydrochloride, and aromatic aldehydes at 100 degrees C. One of the advantages of this new method is the non-use of a metal oxidant such as KMnO4 (greener method) and the stabilization of MnO2 to the zeolite-Y surface via ion bonding. This causes the MnO2 not be leached from the zeolite during the processes of nanocatalyst recycling in organic reactions. This simple approach also has promising features as like as safe, inexpensive and recyclable nanocatalyst, solvent-free reaction, short reaction times, high to excellent yields, and easy isolation of the products.

The cobalt alkyne complex [(prop-2-ynyl)-2-acetoxybenzoate]dicobalthexacarbonyl (Co-ASS) is an auspicious lead, which exhibits its anticancer activity mainly by inhibition of both cyclooxygenases (COX-1 and COX-2). Since COX-2 participates in carcinogenesis, a selective inhibition of that isoenzyme is aimed. To study if fluorination increases the COX-2/COX-1 inhibition ratio of the lead, substitution was respectively performed in the positions 3, 4, 5, and 6 of the aromatic moiety. The complexes 3/4/5F-Co-ASS and to a much lower extent also 6F-Co-ASS showed cytotoxic, antimetabolic, and apoptotic effects in COX-1/2-positive HT-29 and MDA-MB-231 cells and remarkably less activity in the COX-1/2-negative MCF-7 cell line. The metabolic activity in MCF-7 cells was even unaffected up to a concentration of 40 mu M. With exception of 6F-Co-ASS, the complexes strongly reduced the PGE(2) synthesis in HT-29 cells and all complexes inhibited COX-2 more effectively than COX-1 in an assay at isolated enzymes. These findings point to an interference in the COX cascade as part of the mode of antitumor action. The limited cellular effects of 6F-Co-ASS are related to its poor uptake as determined by HR CS AAS/MAS. Moreover, the cellular uptake studies confirm fluorination as beneficial tool for bioanalytical labeling. The higher quantification of fluorine by HR CS MAS makes this method about 5-fold more sensitive than HR CS AAS measuring cobalt. As a further positive result, 3/4/5/6-Co-ASS demonstrated high selectivity to tumor cells due to lack of antimetabolic activity against the non-tumorigenic bone marrow stromal cell line HS-5.

Nrf2 is a transcription factor regulating expression of the Phase II Antioxidant Response and plays an important role in neuroprotection and detoxification. Nrf2 activation is inhibited by interaction with Keap1. Covalent Keap1 inhibitors such as dimethyl fumarate (DMF) and RTA-408 are either on the market or in late stage clinical trials which implies potential benefit of Nrf2 activation. Activation of Nrf2 by disrupting Nrf2-Keap1 interaction through a non-covalent small molecule is an attractive approach with the promise of greater selectivity. However, there are no known non-covalent Nrf2 activators with acceptable pharmacokinetic properties to test the hypothesis in vivo. Based on our early reported work, using structural-based design, followed by extensive SAR exploration, we have identified a novel series of non-covalent Nrf2 activators, with sub-nanomolar binding affinity on Keap1 and single digit nanomolar activity in an astrocyte assay. A representative analog shows excellent oral PK and good Nrf2-dependent gene inductions in kidney. These results provide a peripheral in vivo tool compound to validate the biology of non-covalent activation of Nrf2.

Fucosylated chondroitin sulfates (FuCSs) are a unique type of polysaccharides occurring in sea cucumber that show a variety of biological activities. In particular, well-defined FuCS oligosaccharides, consisting of a trisaccharide repeating unit of beta-D-GalNAc(4,6-diS)-(1 -> 4)-[alpha-L-Fuc(2,4-diS)-(1 -> 3)]-beta-D-GlcUA, display potent anticoagulant activity via selective inhibition of the intrinsic tenase, which could be developed into anticoagulant drugs without bleeding risk. Herein, we report an effective approach to the synthesis of FuCS oligosaccharides, as demonstrated by the successful elaboration of FuCS tri-, hexa-, and nonasaccharides. The syntheses employ an orthogonally protected trisaccharide as a pivotal building block that can be readily converted into the donor and acceptor for glycosidic coupling. In addition, the internal patterns of protecting groups, involving N-trichloroacetyl for N-acetyl group, benzylidene and benzyl groups for sulfonated hydroxyl groups, and benzoyl and methyl esters for free hydroxyl and carboxylic acid, respectively, ensure stereoselective formation of the glycosidic linkages and sequential transformation into the desired FuCS oligosaccharides.
