Vaccinium arboreum is adapted to soils with low organic matter and high pH. It is considered as a potential blueberry rootstock. The objective of this research was to establish a rapid mass propagation protocol of V. arboreum through axillary shoots proliferation with minimum somaclonal variation. Nodal segments from cuttings were cultured on Driver and Kuniyaki walnut medium (DKW) with different cytokinins for initial culture establishment. DKW, woody plant medium (WPM), and Long and Preece medium (LP) were compared for best shoot proliferation. Zeatin (ZT) concentrations from 0 to 4.56 mu M were evaluated for optimizing the concentration. Both in vitro and ex vitro rooting were evaluated. The pH tolerance of in vitro shoots was investigated by adjusting the media pH from 5 to 8.5. Best shoot proliferation was achieved by LP medium supplemented with 2.28 mu M ZT and 0.05 mu M indole-3-butyric acid (IBA). In vitro shoots proliferated best on medium pH 5, though the shoots could survive on pH 8. All the micropropagated shoots successfully rooted by ex vitro rooting after dipping with auxin. All rooted plantlets acclimatized and grew well in greenhouse. Micropropagation through axillary shoots proliferation is an efficient method to propagate true-to-type V. arboreum in large number for future use as rootstock.

Ethnopharmacological relevance: The dried and nearly ripe fruits of Tetradium ruticarpum (A. Juss.) T.G. Hartley (TR) have long been used in treating headache and gastrointestinal disorders in oriental medicine. TR is usually processed by stir-frying with licorice extract before use. Although processing procedure is considered as the way to relieve pungent smell, reduce toxicity, and improve efficacy, its effects on TR’s toxicity and efficacy and bioactive compound profiles are largely unknown. Aim of the study: The purposes of the study are to evaluate the acute toxicity, efficacy and variation of toxic and effective components of TR before and after processing, and to explore the possible mechanism of how the processing procedure affect the quality of TR as a herbal medicine. Materials and methods: Volatile oil, aqueous extract and ethanol extract of raw and processed TR were tested for their acute toxicity, analgesic, and anti-inflammatory effects in mouse models, respectively. To identify potential toxic and effective components, the extracts were analyzed with gas chromatography-mass spectrometry and ultra-performance liquid chromatography – quadrupole time-of-flight mass spectrometry, followed by foldchange-filtering analysis. Results: LD(50)( )and LD5 tests indicated that although the aqueous extract has higher toxicity than volatile oil and ethanol extract, the use of TR is safe under the recommended does. The processing procedure could effectively decrease the toxicity of all three extracts with the largest decrease in volatile oil, which is likely due to the loss of volatile compounds during processing. Analgesic and anti-inflammatory studies suggested that volatile oil and ethanol extract of TR have better efficacy than the aqueous extract and the processing procedure significantly enhanced the efficacy of these two former extracts, whereas processing showed no substantially effects on the bioactivities of aqueous extract. Integrated analysis of animal trial and chromatographic analyses indicated that indole and quinolone type alkaloids, limonoids, amides and 18p-glycyrrhetinic acid were identified as the potential main contributors of TR’s efficacy, whereas hydroxy or acetoxy limonoid derivates and coumarins could be the major causes of toxicity. Moreover, the reduced toxicity and improved efficacy of the processed TR are liked due to the licorice ingredients and altered alkaloids with better solubility. Conclusions: In summary, the integrated toxicity and efficacy analyses of volatile, aqueous and ethanol extracts of TR indicated that the processing procedure could effectively reduce its acute toxicity in all three extracts and enhance its analgesic and anti-inflammatory effects in volatile and ethanol extracts. The promising candidate compounds related to the toxicity and efficacy of TR were also identified. The results could expand our understanding of the value of the standard processing procedure of TR, be valuable to the quality control of TR manufacturing and administration, as well as support clinical rational and safety applications of this medicinal plant.

Herein, we report a base-promoted Zn(II)-bis(oxazoline)-catalyzed one-pot Friedel-Crafts alkylation/Michael addition of 3-(indol-4-yl)acrylonitrile derivatives with trans-beta-nitrostyrenes to yield the tricyclic core of the ergoline skeleton in up to 71% yield and 85% ee. During the purification of 3-(indol-4-yl)acrylonitrile, the key substrate for catalytic studies, a novel trans-cis-trans-cyclobutane derivative, thought to be formed via a [2+2] light-promoted cycloaddition, was identified by X-ray crystallographic analysis. Finally, a novel class of 4-substituted bis(indole)methane derivatives were serendipitously prepared in excellent yield by reacting 4-substituted indole derivatives with 4-nitrobenzaldehyde. One bis(indole)methane was characterized by X-ray crystallographic analysis.

Highly enantioselective C2 alkylation and inverse-electron-demand [3 + 2]-cycloaddition of 3-methylindoles with 2,2′-diester aziridine were accomplished. The chemodivergent synthesis provided an access to two kinds of chiral indole derivatives in good yields and stereoselectivities in the presence of the chiral N,N’-dioxide/Tm(OTf)(3) or N,N’-dioxide/Ho(OTOf)(3) complexes. An eight-coordinated mode of N,N’-dioxide/Tm(OTf)(3) complex was confirmed by X-ray crystal diffraction to interpret the roles of additives H2O and 1,4-dioxane. In addition, the control experiments indicated that the substituent of the indole nitrogen atom determined the conversion patterns in the divergent reactions.

Indole-3-acetic acid (IAA) is an imperative phytohormone for plant growth and development. Ectomycorrhizal fungi (ECM) are able to produce IAA. However, only a few studies on IAA biosynthesis pathways in ECM fungi have been reported. This study aimed to investigate the IAA biosynthesis pathway of six ECM cultures including Astraeus odoratus, Gyrodon suthepensis, Phlebopus portentosus, Pisolithus albus, Pisolithus orientalis and Scleroderma suthepense. The results showed that all ECM fungi produced IAA in liquid medium that had been supplemented with L-tryptophan. Notably, fungal IAA levels vary for different fungal species. The detection of indole-3-lactic acid and indole-3-ethanol in the crude culture extracts of all ECM fungi indicated an enzymatic reduction of indole-3-pyruvic acid and indole-3-acetaldehyde, respectively in the IAA biosynthesis via the indole-3-pyruvic acid pathway. Moreover, the tryptophan aminotransferase activity confirmed that all ECM fungi synthesize IAA through the indole-3-pyruvic acid pathway. Additionally, the elongation of rice and oat coleoptiles was stimulated by crude culture extract. This is the first report of the biosynthesis pathway of IAA in the tested ECM fungi.

UV-vis absorption and fluorescence spectra of a series of merocyanines with varying heterocyclic donor and carbonyl-comprising acceptor groups have been studied in frozen ethanol at 77 K. Due to a greater polarity of a frozen solvent matrix in comparison with the liquid solvent, the electronic structure of donor-pi-acceptor molecules in the former becomes much more dipolar. The resulting spectral effects depend on the donor-acceptor abilities of the terminal groups. In the case of positively solvatochromic indole-based dyes comprising the 1,3-indandione or barbituric acceptors, going from 293 to 77 K results in a narrowing and bathochromic shifts of absorption bands. Vice versa, for more dipolar reversely and negatively solvatochromic merocyanines comprising the thiobarbituric acceptor-group, the solvent freezing leads to a broadening and hypsochromic shifts of the absorption bands, which is very unique, taking into account that the solute vibrations/rotations should decrease in a frozen solvent. In all cases, the fluorescence bands are shifted hypsochromically at cryotemperature and are closely mirror-like to the absorption ones, which, along with the smaller Stokes shifts, has been explained by the inhibited solvent rearrangement in the frozen matrix, resulting in a greater similarity of the ground state S-0 and the fluorescent excited state S-1. The deductions about the electronic structure of the studied dyes in the ground and excited states and its dependence on the donor-acceptor properties of the end groups correlate well with the results of the PCM/(TD)-DFT calculations performed within the four-level diagram of electronic transitions.

A versatile dual H-bonds and pi-pi-interaction strategy that enables enantioselective remote C6-selective C-H functionalization of 2,3-disubstituted indoles was first reported. The N-H bond of indole was pivotal to achieve the C6 functionalization with excellent yield and enantioselectivity. Furthermore, this methodology leads to the efficient construction of numerous enantioenriched C6-functionalized indole products under mild reaction conditions employing different electrophiles. Preliminary cell proliferation investigations revealed that the synthesized chiral C6-substituted indole derivatives had potential anticancer activities.
