Marine organisms are recognized as a source of compounds with interesting biological activities. Vibrio neocaledonicus has been reported on for its high effectiveness against corrosion in metals but it has been little studied for its chemical and biological activities. In this study, four compounds were isolated from V. neocaledonicus: indole (1); 1H-indole-3-carboxaldehyde (2); 4-hydroxybenzaldehyde (3) and Cyclo (-Pro-Tyr) (4); using a bioassay-guided method, since in a previous study it was found that the ethyl acetate extract was active on the enzymes acetylcholinesterase (AChE), alpha-glucosidase (AG) and xanthine oxidase (XO). The inhibitory activities of the three compounds against AChE, AG and XO was also evaluated. In addition, the enzymatic inhibitory activity of indole to the toxins from the venom of Bothrops asper was tested. Results showed that indole exhibited strong inhibitory activity to AG (IC50 = 18.65 +/- 1.1 mu M), to AChE, and XO (51.3% and 44.3% at 50 mu g/mL, respectively). 1H-indole-3-carboxaldehyde displayed strong activity to XO (IC50 = 13.36 +/- 0.39 mu M). 4-hydroxybenzaldehyde showed moderate activity to XO (50.75% at 50 mu g/mL) and weak activity to AChE (25.7% at 50 mu g/mL). Furthermore, indole showed a significant in vitro inhibition to the coagulant effect induced by 1.0 mu g of venom. The findings were supported by molecular docking. This is the first comprehensive report on the chemistry of V. neocaledonicus and the bioactivity of its metabolites.

Indole sesquiterpene sespendole, which has been isolated from the filamentous fungus Pseudobotrytis terrestris FKA-25, is a specific inhibitor of lipid droplet synthesis in mouse macrophages. The biosynthetic pathway that involves genes encoding six enzymes (spdEMBQHJ) was elucidated through heterologous expression of spd genes in Aspergillus oryzae, biotransformation experiments, and in vitro enzymatic reactions with a recombinant protein, thereby revealing the mechanism underlying the characteristic modification on the indole ring, catalyzed by a set of prenyltransferase (SpdE)/cytochrome P450 (SpdJ) enzymes. Functional analysis of the homologous genes encoding these enzymes involved in the biosynthesis of lolitrem allowed a biosynthetic pathway for the bicyclic ring skeleton fused to the indole ring to be proposed.

C7-Decorated indoles are important structural motifs present in a plethora of bioactive and pharmaceutical compounds. Early stage developments for C7 modifications were realized through directed metallation (DOM) and subsequent quenching with suitable electrophiles or by halogenation with Cu(ii) halides. Direct C-7 functionalization of indoles is comparatively difficult compared to functionalization at C-2 and C-3 positions owing to the inherent reactivity of the pyrrole-type ring. However, recently transition-metal-catalyzed auxiliary assisted site-selective C-7 functionalization of indoles has emerged as an elegant synthetic tool for carbon-carbon and carbon-heteroatom bond formation to diversify the indoles. This article covers the advancement, application and mechanistic underpinnings of the evolved transformations of the otherwise inert C7-H bond up to October 2018.

Due to their biological activity, indoles and substituted indoles have attracted considerable attention from both synthetic and medicinal scientists. Much effort has been directed toward the development of methods for the functionalization of the indole nucleus. The protocol uses a catalytic amount of catalyzed platinum as a promoting agent, producing N-allylated indoles in considerable yields. Moreover, water, with its large heat capacity, is one of the most abundant molecules on earth. The use of water as a solvent may bring about many environmental benefits. Herein, we have demonstrated that the platinum-catalyzed selective N-allylation of 2,3-disubstituted indoles proceeds in water. This method provides a simple, convenient, and efficient way to afford a high yield of N-allylated indoles.

Changes in the plant water status, biochemical and hormonal responses, were investigated in three olive cultivars (Arbequina, Arbosana and Chetoui) grown in a super-high-density orchard under partial root-zone drying (PRD) irrigation. Four irrigation treatments were applied during two growing seasons (2015 and 2016); control treatment (100 % ETc) irrigated at 100 % of crop evapotranspiration on both parts of the root-zone and three PRD irrigation treatments (100 % PRD, 75 % PRD and 50 % PRD) irrigated at 100 %, 75 %, and 50 % of crop evapotranspiration only on one alternated part of the root-zone. The results indicated that the three studied olive cultivars showed a clear difference in their response to PRD irrigation. Arbequina cultivar has shown a conservative strategy for using water since relative water content (RWC) and stem water potential (Psi(stem)) were reduced more in Arbosana and Chetoui under PRD irrigation. In fact, PRD irrigation has led to a strong activation of secondary metabolites with antioxidant properties such as pigments, phenols and flavonoids. Other metabolic changes, including the accumulation of soluble sugars and proline have been also triggered by PRD irrigation. Among the studied cultivars, Arbequina displayed the highest levels of proline, total soluble sugars, phenols and flavonoids, and the lowest ones for Malondialdehyde (MDA) and hydrogen peroxide (H2O2). The increase in Superoxide dismutase (SOD), catalase (CAT) and guaiacol peroxidase (POD) activity and the reduction in polyphenoloxidase (PPO) activity under PRD irrigation were more pronounced in 2016 season with highest activities obtained from cultivar Arbequina. For all the three cultivars, PRD irrigation increased phytohormones concentration in both, roots and leaves and the highest levels were recorded in 2016. In leaves, Arbequina showed the lowest levels of abscisic acid (ABA), and the highest levels of jasmonic acid (JA), salicylic acid (SA) and indole-3-acetic acid (IAA). PRD irrigation also induces a higher accumulation of ABA, JA and IAA in dried roots than in wetted ones. Taken together, physiological and biochemical mechanisms induced by PRD irrigation were more effective in Arbequina suggesting better protection of their foliar functions compared to other cultivars and its higher adaptability to PRD.

Catalytic transformation of alcohols via metal-catalyzed cross-coupling reactions is very important, but it typically relies on a multistep procedure. We here report a dynamic kinetic cross-coupling approach for the direct functionalization of alcohols. The feasibility of this strategy is demonstrated by a nickel-catalyzed cross-electrophile arylation reaction of benzyl alcohols with (hetero)aryl electrophiles. The reaction proceeds with a broad substrate scope of both coupling partners. The electron-rich, electron-poor, and ortho-/meta-/para-substituted (hetero)aryl electrophiles (e.g., Ar-OTf, Ar-I, Ar-Br, and inert Ar-Cl) all coupled well. Most of the functionalities, including aldehyde, ketone, amide, ester, nitrile, sulfone, furan, thiophene, benzothiophene, pyridine, quinolone, Ar-SiMe3, Ar-Bpin, and Ar-SnBu3, were tolerated. The dynamic nature of this method enables the direct arylation of benzylic alcohol in the presence of various nucleophilic groups, including nonactivated primary/secondary/tertiary alcohols, phenols, and free indoles. It thus offers a robust alternative to existing methods for the precise construction of diarylmethanes. The synthetic utility of the method was demonstrated by a concise synthesis of biologically active molecules and by its application to peptide modification and conjugation. Preliminary mechanistic studies revealed that the reaction of in situ formed benzyl oxalates with nickel, possibly via a radical process, is an initial step in the reaction with aryl electrophiles.
