Dioxetane intermediates readily decompose to chemiluminescent triplet carbonyls, giving rise to what has been paradoxically called photochemistry in the dark. In this issue of Photochemistry and Photobiology, Bechara et al. report on mechanistic advances in such a reaction. With the use of horseradish peroxidase for isobutyraldehyde-derived triplet acetone, light emission from acetone and singlet oxygen can be quenched. The experiments reveal that the reaction depends on oxygen and the amino acid. The analysis reveals that free tryptophan is a target of this form of carbonyl stress, with the efficient formation of mono-, bi- and tricyclic compounds (N-formylkynurenine, indoline, 1 lambda(2)-indole and 3H-indoles).

A novel series of oxo-1,2,3,4-tetrahydropyrazino[1,2-a]indoles were synthesized via a two-step pathway. In the first step, Ugi-four-component condensation of 2-formylindole, amines, (E)-4-alkoxy-4-oxobut-2-enoic acids, and isocyanides gave the corresponding Ugi-adducts. This adduct underwent intramolecular hydroamination in the presence of K2CO3 in CH3CN at room temperature to afford diastereoselective synthesis of a range of oxo-1,2,3,4-tetrahydropyrazino[1,2-a]indoles. A comparison of experimentally observed CD and UV-visible spectra with the theoretical DFT calculated ECD spectra was used to predict the major diastereomer.

The limited bioavailability of plant-derived natural products with anticancer activity poses major challenges to the pharmaceutical industry. An example of this is camptothecin, a monoterpene indole alkaloid with potent anticancer activity that is extracted at very low concentrations from woody plants. Recently, camptothecin biosynthesis has been shown to become biotechnologically amenable in hairy-root systems of the natural producer Ophiorrhiza pumila. Here, time-course expression and metabolite analyses were performed to identify novel transcriptional regulators of camptothecin biosynthesis in O. pumila. It is shown here that camptothecin production increased over cultivation time and that the expression pattern of the WRKY transcription factor encoding gene OpWRKY2 is closely correlated with camptothecin accumulation. Overexpression of OpWRKY2 led to a more than three-fold increase in camptothecin levels. Accordingly, silencing of OpWRKY2 correlated with decreased camptothecin levels in the plant. Further detailed molecular characterization by electrophoretic mobility shift, yeast one-hybrid and dual-luciferase assays showed that OpWRKY2 directly binds and activates the central camptothecin pathway gene OpTDC. Taken together, the results of this study demonstrate that OpWRKY2 acts as a direct positive regulator of camptothecin biosynthesis. As such, a feasible strategy for the over-accumulation of camptothecin in a biotechnologically amenable system is presented.

This study investigated the plant growth-promoting effects of Leclercia adecarboxylata MO1 for Zn stress mitigation and plant growth improvement in Zn-contaminated soil. Results demonstrated that L. adecarboxylata MO1 produced siderophores that could solubilize Zn and silicate, had a tolerance to elevated levels of Zn supplementation (2 and 5 mM) in growth mediums, and produced significant amounts of indole-3-acetic acid (IAA). It was also found to promote plant growth under both control conditions and Zn toxicity (2 and 5 mM). Furthermore, L. adecarboxylata MO1 positively regulated physiochemical attributes by decreasing hydrogen peroxide (H2O2) and Zn uptake in both roots and shoots, improving antioxidant systems (e.g. catalase (CAT), peroxidase (POD), polyphenol peroxidase (PPO), superoxide anion (SOA), lipid peroxidation (MDA), and glutathione (GSH)), and reducing stress-responsive endogenous abscisic acid (ABA) and salicylic acid (SA) in plants grown under Zn toxicity of 2 and 5 mM, compared with non-inoculated plants.

Clostridium (Clostridioides) difficile infection (CDI) is associated with dysbiosis. C. difficile has a characteristic propensity to persist and recur 1 to 4 weeks after treatment, but the mechanism is unknown. We hypothesized that C. difficile may persist by manipulating the intestinal microenvironment, thereby hampering gut microbiota reconstitution following antibiotic-mediated dysbiosis. By screening stools from CDI patients for unique markers, a metabolite identified to be indole by mass spectrometry and Fourier transform infrared spectroscopy was identified. The average fecal indole concentration detected in CDI patients (n = 216; mean, 1,684.0 +/- 84.4 mu M) was significantly higher than in stools of patients with non-C. difficile diarrhea (n = 204; mean, 762.8 +/- 53.8 mu M). Certain intestinal bacteria, but not C. difficile, produce indole, a potent antimicrobial antioxidant. Remarkably, C. difficile induced other indole-producing gut microbes to produce increasing amounts of indole. Furthermore, a C. difficile accessory gene regulator 1 quorum sensing system mutant cannot induce indole, but complementation of the mutant strain with the wild-type gene restored its ability to induce indole production. Indole tolerance assays indicated that the amount of indole required to inhibit growth of most gut-protective bacteria was within the range detected in the CDI stools. We think that a high indole level limits the growth of beneficial indole-sensitive bacteria in the colon and alters colonization resistance and this might allow C. difficile to proliferate and persist. Together, these results reveal a unique mechanism of C. difficile persistence and provide insight into complex interactions and chemical warfare among the gut microbiota. IMPORTANCE Clostridium difficile infection is the leading cause of hospital-acquired and antibiotic-associated diarrhea worldwide. C. difficile flourishes in the colon after the diversity of the beneficial and protective gut microbiota have been altered by antibiotic therapy. C. difficile tends to persist, as does dysbiosis, encouraging recurrence a few days to weeks after treatment, and this further complicates treatment options. Here, we show that C. difficile might persist by manipulating the indigenous microbiota to produce indole, a bioactive molecule that inhibits the growth and reconstitution of the protective gut microbiota during infection. This discovery may explain a unique strategy C. difficile uses to control other bacteria in the colon and provide insight into the complex interactions and chemical warfare among the gut microbiota.
