Arthrobacter pascens ZZ21 is a plant-beneficial, fluoranthene-degrading bacterial strain found in the rhizosphere. The production of the phytohormone indole-3-aectic acid (IAA) by ZZ21 is thought to contribute to its ability to promote plant growth and remediate fluoranthene-contaminated soil. Using genome-wide analysis combined with metabolomic and high-performance liquid chromatography-mass spectrometry (HPLC-MS) analyses, we characterized the potential IAA biosynthesis pathways in A. pascens ZZ21. IAA production increased 4.5-fold in the presence of 200 mgL(-1) tryptophan in the culture medium. The transcript levels of prr and aldH, genes which were predicted to encode aldehyde dehydrogenases, were significantly upregulated in response to exogenous tryptophan. Additionally, metabolomic analysis identified the intermediates indole-3-acetamide (IAM), indole-3-pyruvic acid (IPyA), and the enzymatic reduction product of the latter, indole-3-lactic acid (ILA), among the metabolites of ZZ21, and subsequently also IAM, ILA, and indole-3-ethanol (TOL), which is the enzymatic reduction product of indole-3-acetaldehyde, by HPLC-MS. These results suggest that the tryptophan-dependent IAM and IPyA pathways function in ZZ21.

Indole is an important chemical that can be directly obtained from wash oil mixtures. In this work, several tetraethyl ammonium amino acid (TAAA) ionic liquids (ILs) were designed to separate indole from model wash oil through forming hydrogen bonds. The effects of important factors, such as stirring time, TAAA type, indole concentration, temperature, and TAAA:indole mole ratio, on indole separation were investigated. It is found that these TAAAs can separate indole from model wash oil with separation efficacy up to 98.0% (for tetraethylammonium L-alanine ionic liquid), and the ultimate indole concentration is 1.6 g/dm(3). This separation process takes less than 5 min. Also, for one kind of TAAA, the ultimate indole concentrations are almost constant despite different initial indole concentrations. The maximum distribution coefficients of indole are 200.9 at the studied conditions. We have also found that water content in TAAA shows a negative effect on indole separation, which inspired us to design a process for TAAA regeneration using water. After regeneration, TAAA can be reused, and the separation efficacy of indole is not significantly reduced. The FT-IR results show that there are hydrogen bonds between TAAAs and indole. Finally, we compared the TAAA method to other methods and demonstrated the advantages.

Green and Efficient Synthesis of 3-Pyrazolyl Indoles in Water

A green and efficient synthesis of 3-pyrazolyl indoles was developed by the cyclocondensation reaction of beta-ethylthio-beta-indolyl-alpha, beta-unsaturated ketones with semicarbazide hydrochloride as hydrazine equivalent in the presence of 3 equiv. of PEG-400(1a/PEG mole ratio of 1:3) in reflux water. This procedure did not require toxic hydrazine and product purification, eliminating the use of toxic liquid chemicals.

Computational design of an intramolecular photocyclization reaction with state-selective reactivity: a strategy for indole synthesis

The development of a convenient and environmentally friendly indole synthesis method is of great methodological and pharmaceutical interest. In this work, we discovered an intramolecular photocyclization of carbonyls and tertiary amines for indole synthesis without relying on photocatalysts. A wide range of functional indoles were prepared with moderate to excellent yields under mild reaction conditions. Furthermore, our extensive quantum mechanics (QM) calculations and synthesis experiments revealed the ‘state-selective reactivity’ feature of this reaction, and different substrate types can achieve different yields through this feature. This new insight into the interplay between the ‘state-selective reactivity’ and the yields emphasizes its importance and gives guidance regarding the ‘state-selective reactivity’ for the high yield of various indole derivatives.
