The organic compound 2-phenylethanol (2PE) has a pleasant floral scent and is intensively used in the cosmetic and food industries. Microbial production of 2PE by phenylalanine bioconversion or de novo biosynthesis from sugar offer sustainable, reliable and natural production processes compared to chemical synthesis. Despite the ability of Saccharomyces cerevisiae to naturally synthesize 2PE, de novo synthesis in high concentration and yield remains a metabolic engineering challenge. Here, we demonstrate that improving phosphoenolpyruvate supply by expressing pyruvate kinase variants and eliminating the formation of p-hydroxy-phenylethanol without creating tyrosine auxotrophy significantly contributed to improve 2PE production in S. cerevisiae. In combination with the engineering of the aromatic amino acid biosynthesis and Ehrlich pathway, these mutations enabled better connection between glycolysis and pentose phosphate pathway optimizing carbon flux towards 2PE. However, attempts to further connect these two parts of central carbon metabolism by redirecting fructose-6P towards erythrose-4P by expressing a phosphoketolase-phosphotransacetylase pathway did not result in improved performance. The best performing strains were capable of producing 13mM of 2PE at a yield of 0.113 mol mol-1, which represents the highest yield for de novo produced 2PE in S. cerevisiae and other yeast species.

One of the fundamental and highly valuable transformations in organic chemistry is the nucleophilic substitution of alcohols. Traditionally, these reactions require strategies that employ stoichiometric hazardous reagents and are associated with difficulty in purification of the by-products. To overcome these challenges, here, we report a simple route toward the diverse conversion of alcohols via an SN2 pathway, in which blue light-promoted iodination is used to form alkyl iodide intermediates from simple unreactive alcohols. The scope of the process tolerates a range of nucleophiles to construct C-N, C-O, C-S, and C-C bonds. Furthermore, we also demonstrate that this method can be used for the preparation and late-stage functionalization of pharmaceuticals, as highlighted by the syntheses of thiocarlide, butoxycaine, and pramoxine.

A series of novel hybrid compounds between indolo[b]tetrahydrofuran and imidazolium salts were prepared from tryptophol by four steps of Sharpless epoxidation, amidation, coupling and salt formation. Their structures were confirmed by 1H NMR, 13C NMR, HRMS and X-ray crystallographic analysis. These compounds were evaluated in vitro against a panel of human tumor cell lines. The results showed that 1-((3aR,8aS)-3,3a-dihydro-3a-hydroxy-2H-furo[2,3-b]indol-8(8aH)-yl)etha-none-3-(2-(naphthalen-2-yl)-2-oxoethyl)-5,6-dimethyl-1H-benzo[d]-imidazol-3-ium bromide (20) and 1-((3aR,8aS)-3,3a-di-hydro-3a-hydroxy-2H-furo[2,3-b]indol-8(8aH)-yl)ethanone-3-(2-naphthylmethyl)-5,6-dimethyl-1H-benzo[d]imidazol-3-ium bromide (22) exhibited higher inhibitory activity selectively against SMMC-7721, MCF-7 and SW480 cell lines compared with DDP. In particular, 1-((3aR,8aS)-3,3a-dihydro-3a-hydroxy-2H-furo[2,3-b]indol-8(8aH)-yl)ethanone-3-(2-bromobenzyl)-5,6-dimethyl-1H-benzo[d]imidazol-3-ium bromide (24) was more selective to SW-480 cell lines with IC50 values 2.0-fold lower than DDP.

We have previously reported that squalene overproducing yeast self-downregulate the expression of the ethanol pathway (non-essential pathway) to divert the metabolic flux to the squalene pathway. In this study, the effect of co-production of squalene and ethanol on other non-essential pathways (fusel alcohol pathway, FA) of Saccharomyces cerevisiae was evaluated. However, before that, 13 constitutive promoters, like IRA1p, PET9p, RHO1p, CMD1p, ATP16p, USA3p, RER2p, COQ1p, RIM1p, GRS1p, MAK5p, and BRN1p, were engineered using transcription factor bindings sites from strong promoters HHF2p (?300 to ?669 bp) and TEF1p (?300 to ?579 bp), and employed to co-overexpress squalene and ethanol pathways in S. cerevisiae. The FSE strain overexpressing the key genes of the squalene pathway accumulated 56.20 mg/L squalene, a 16.43-fold higher than wild type strain (WS). The biogenesis of lipid droplets was stimulated by overexpressing DGA1 and produced 106 mg/L squalene in the FSE strain. AFT1p and CTR1p repressible promoters were also characterized and employed to downregulate the expression of ERG1, which also enhanced the production of squalene in FSE strain up to 42.85-(148.67 mg/L) and 73.49-fold (255.11 mg/L) respectively. The FSE strain was further engineered by overexpressing the key genes of the ethanol pathway and produced 40.2 mg/mL ethanol in the FSE1 strain, 3.23-fold higher than the WS strain. The FSE1 strain also self-downregulated the expression of the FA pathway up to 73.9%, perhaps by downregulating the expression of GCN4 by 2.24-fold. We demonstrate the successful tuning of the strength of yeast promoters and highest coproduction of squalene and ethanol in yeast, and present GCN4 as a novel metabolic regulator that can be manipulated to divert the metabolic flux from the non-essential pathway to engineered pathways.

In wine phenolics analysis, extraction induces many artefacts due to oxidation, isomerization or hydrolysis. Moreover, extraction is never exhaustive as wine is actually a partially colloidal solution; as a consequence, the recovery of many substances is low. The assay of many phenolics, based upon a recovery ratio determined from the extraction of an artificial mixture, is then generally wrong. The analysis via direct injection of wine into the chromatographic column avoids most of these difficulties, but requires an efficient and thermostated column, a perfectly adapted gradient and the use of a diode array detector. In some cases confirmation may be obtained by electrochemical or fluorometric detection. Up to 30 compounds may be identified and assayed including catechins and proanthocyanidins, caffeic, p-coumaric and ferulic acids and their combinations with tartaric acid, vanillic, gallic, protocatechuic, p-hydroxybenzoic, syringic acids, tyrosol, tryptophol, flavonols and flavonol glycosides, resveratrol, etc.

The transition metal-catalyzed transformation of otherwise inert C-H bonds into substituted alkenes offers a versatile tool for the synthesis of value added olefinic molecules. Recent developments in the directing group assisted C-H activation approach ensured high levels of positional selectivity. A vast number of coordinating groups have been utilized in directed C-H alkenylation, which are often not removable after the desired transformation. However, the concept of easily removable or traceless directing group strategy overcomes this limitation and enables site-selective C-H alkenylation of relevance to academia and the practitioners in industry. Various easily removable or transformable directing groups utilized in the transition metal-catalyzed oxidative C-H alkenylations are discussed in this review until February 2017.

The determination of appropriate dietary strategies for the prevention of chronic degenerative diseases, cancer, diabetes, and cardiovascular diseases remains a challenging and highly relevant issue worldwide. Epidemiological dietary interventions have been studied for decades with contrasting impacts on human health. Moreover, research scientists and physicians have long debated diets encouraging alcohol intake, such as the Mediterranean and French-style diets, with regard to their impact on human health. Understanding the effects of these diets may help to improve in the treatment and prevention of diseases. However, further studies are warranted to determine which individual food components, or combinations thereof, have a beneficial impact on different diseases, since a large number of different compounds may occur in a single food, and their fate in vivo is difficult to measure. Most explanations for the positive effects of Mediterranean-style diet, and of the French paradox, have focused largely on the beneficial properties of antioxidants, among other compounds/metabolites, in foods and red wine. Wine is a traditional alcoholic beverage that has been associated with both healthy and harmful effects. Not withstanding some doubts, there is reasonable unanimity among researchers as to the beneficial effects of moderate wine consumption on cardiovascular disease, diabetes, osteoporosis, and longevity, which have been ascribed to polyphenolic compounds present in wine. Despite this, conflicting findings regarding the impact of alcohol consumption on human health, and contradictory findings concerning the effects of non-alcoholic wine components such as resveratrol, have led to confusion among consumers. In addition to these contradictions and misconceptions, there is a paucity of human research studies confirming known positive effects of polyphenols in vivo. Furthermore, studies balancing both known and unknown prognostic factors have mostly been conducted in vitro or using animal models. Moreover, current studies have shifted focus from red wine to dairy products, such as cheese, to explain the French paradox. The aim of this review is to highlight the contradictions, misconceptions, and scientific facts about wines and diets, giving special focus to the Mediterranean and French diets in disease prevention and human health improvement. To answer the multiplicity of questions regarding the effects of diet and specific diet components on health, and to relieve consumer uncertainty and promote health, comprehensive cross-demographic studies using the latest technologies, which include foodomics and integrated omics approaches, are warranted.
