Strictosidine synthase (STR1) catalyzes a Pictet-Spengler reaction (PSR) forming strictosidine, a likely biosynthetic key to all higher plant monoterpenoid indole alkaloids. Increasing the biocatalytic capacity of the enzyme may make it a powerful tool for generation of compound libraries with enhanced structural diversity and pharmaceutical activity. Herein two production routes of a rare class of azepino[3,4,5-cd]-indoles are developed: a complementary STR1-dependent chemoenzymatic and stereoselectively chemical route to an epimeric 1H-azepino[3,4,5-cd]indolyl strictosidine or vincoside, respectively. Mechanisms of the asymmetric catalysis are proposed based on computational calculations and X-ray analysis of STR1-ligand complexes. Further chemoenzymatic manipulation of the complementary PSR products resulted in several diverse and complex azepino-indole alkaloids, in which two alkaloids with the epimeric center directs the discovered antimalaria activity: 4a(S) with IC50 approximate to 3.4 mu M, 4 beta(R) with IC50 approximate to 6.1 mu M. The chemoenzymatic synthesis may significantly extend the applications of the enantiospecific STR1-based PSR in the future.

Efficient Copper-Catalysed Synthesis of Carbazoles by Double N-Arylation of Primary Amines with 2,2 ‘-Dibromobiphenyl in the Presence of Air

An efficient Cu-catalyzed synthesis of carbazole derivatives is reported, which proceeds by double C-N coupling reactions of 2,2 ‘-dibromobiphenyl and amines in the presence of air. The reaction is robust, proceeds in high yields, and tolerates a series of amines including neutral, electron-rich, electron-deficient aromatic amines and aliphatic amines.

Enhanced anaerobic degradation of quinoline and indole with dried Chlorella pyrenoidosa powder as co-metabolic substance

In coal gasification wastewater (CGW), nitrogen heterocyclic compounds (NHCs) are important refractory compounds. However, NHCs negatively impact human health and the environment due to its toxic, carcinogenic, and mutagenic properties. The main objective of this study was to determine the feasibility of Chlorella pyrenoidosa as a co-metabolite in enhancing anaerobic degradation of NHCs in CGW. So far, there have been few studies on enhanced anaerobic degradation with Chlorella pyrenoidosa as a cometabolic substance. It was speculated that Chlorella pyrenoidosa had certain feasibility in the enhanced degradation of NHCs. Anaerobic Reactor 1 was operated as a control, while Reactor 2 was operated with the addition of Chlorella pyrenoidosa. When the concentration of Chlorella pyrenoidosa was 100 mu g/L, Reactor 2 showed optimum degradation ratios on quinoline (100%) and indole (100%). Variations in the concentrations of Chlorella pyrenoidosa did not benefit the degradation efficiency of the reactor, whereby low dosages were not conducive for the microorganism’s growth and high dosages resulted in a competitive inhibition between the Chlorella powder and refractory compounds. In the effluent of Reactor 1, quinoline and indole concentrations were 12.79 +/- 1.21 and 18.45 +/- 1.11 mg/L, respectively. In Reactor 2, neither quinoline nor indole were detected. Acute bio-toxicity tests indicated a decrease in toxicity with the addition of Chlorella powder, hence reducing the inhibitions on seed germination and root elongation. The addition of Chlorella powder resulted in the increase of tryptophan protein and polysaccharide content in the extracellular polymeric substance of anaerobic sludge. In Reactor 2, bacterial community structures became more diverse and richer. Archaea communities became richer, but diversity declined. In the enhanced anaerobic degradation of NHCs, Chlorella pyrenoidosa powder was found to be an effective co-metabolite. (C) 2020 Published by Elsevier Ltd.

A Green Approach to the Synthesis of Novel Indole Substituted 2-Amino-4,5-dihydro-3-furancarbonitriles in Water

2-Amino-4,5-dihydro-3-furancarbonitriles (ADFCs) have attracted much attention due to their utility as valuable synthetic intermediates for the preparation of a series of acyclic and cyclic organic compounds. On the other hand, indoles substituted with furans are highly interesting compounds displaying a wide range of biological and pharmaceutical activities. However, to the best of our knowledge, indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles have not been previously reported. A new and efficient synthesis of indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles has been developed in two steps using water as a solvent. The first step of the sequence involves three-component reaction of phenylglyoxals, indoles and malononitrile under aqueous and catalyst-free conditions for the synthesis of indole substituted beta,beta-dicyanoketones. Reduction of the obtained beta,beta-dicyanoketones with sodium borohydride in water at room temperature afforded the indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles in good yields. Several substituted phenylglyooxals were reacted smoothly with indole or 2-methylindole and malononitrile to give the corresponding indole substituted beta,beta-dicyanoketones in good yields. Treatment of the obtained beta,beta-dicyanoketones with sodium borohydride in water furnished exclusively the indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles in good yields. We have developed an efficient straightforward access to indole substituted beta,beta-dicyanoketones by one-pot three-component reaction of phenylglyoxals, indoles and malononitrile. The synthetic utility of obtained indole substituted beta,beta-dicyanoketones has been outlined by the preparation of indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles. The advantage of catalyst-free, atom-economical and environmental benignity render it promising methods for preparation of indole substituted 2-amino-4,5-dihydro-3-furancarbonitriles.
