Enantioselective Halocyclization of Indole Derivatives: Using 1,3-Dihalohydantoins with Anionic Chiral Co(III) Complexes

Highly enantioselective halocyclization reactions of indole derivatives, including tryptophols and tryptamines, have been accomplished by means of anionic chiral Co(III) complexes and 1,3-dihalohydantoins (as little as 0.50 equiv). 3-Halo-fused indolines were obtained in excellent yields (up to 98%) and enantioselectivities (up to 98% ee), employing the chiral anion phase-transfer-catalysis strategy.

The Primary Physiological Roles of Autoinducer 2 in Escherichia coli Are Chemotaxis and Biofilm Formation

Autoinducer 2 (AI-2) is a ubiquitous metabolite but, instead of acting as a universal signal, relatively few phenotypes have been associated with it, and many scientists believe AI-2 is often a metabolic byproduct rather than a signal. Here, the aim is to present evidence that AI-2 influences both biofilm formation and motility (swarming and chemotaxis), using Escherichia coli as the model system, to establish AI-2 as a true signal with an important physiological role in this bacterium. In addition, AI-2 signaling is compared to the other primary signal of E. coli, indole, and it is shown that they have opposite effects on biofilm formation and virulence.

AgSbF6-Catalyzed Tandem Reaction of 2-Alkynylanilines with Cyclic Enynones: Efficient access to 3-Furo[3,2-c]chromenylindoles and Related Scaffolds

A simple, mild, catalytic and efficient method for the straightforward synthesis of an interesting class of a range of 2-aryl/alkyl-substituted-3-(2-aryl/alkyl-4H-furo[3,2-c]chromen-4-yl)-1H-indoles in good to high yields is reported for the first time. This atom-efficient method proceeds via AgSbF6-catalyzed one-pot sequential intramolecular hydroamination (C-N bond formation) of 2-alkynylanilines followed by Friedel-Crafts alkylation/oxa-cyclization (creation of new C-C and C-O bonds) reaction between in situ generated 2-substituted indoles and several cyclic enynones.

Design, synthesis, in silico molecular modelling studies and biological evaluation of novel indole-thiazolidinedione hybrid analogues as potential pancreatic lipase inhibitors

Pancreatic lipase (PL) is a key enzyme responsible for the digestion of dietary triglycerides; hence its inhibition is considered as a promising target for the management and/or treatment of obesity. A new series of indole-thiazolidinedione (TZD) hybrid analogues were synthesized using a molecular hybridisation approach and evaluated for their anti-obesity effects via PL inhibition. The targeted analogues were synthesized via the condensation reaction between various substituted isatin with TZD in the presence of aqueous KOH in methanol. Amongst the synthesized analogues, 7k and 7m exhibited a potential PL inhibitory activity (IC50 – 7.30 and 9.51 mu M, respectively). Kinetic study of these potent analogues revealed their competitive mode of enzyme inhibition. This fact was confirmed via fluorescence spectroscopy which further suggested the presence of one binding site for the synthesized analogues. Molecular docking of the synthesized analogues was performed using human PL (PDB ID: ; 1LPB). The obtained MolDock scores were aligned with the in vitro PL inhibitory activity (Pearson’s r = 0.9108, p < 0.05). Moreover, a stable conformation of the 1LPB-ligands suggested the stability of these complexes in the dynamic environment. These studies provided a basis for the potential role of the indole-TZD hybrids in PL inhibition and further optimization might result in the development of new lead candidates for obesity treatment.

Synthesis and antibacterial activity of new hybrid derivatives of 5-sulfamoyl-1H-indole and 4-thiazolidinone groups

The synthesis of a series of new 3-phenyl-5-sulfamoyl-N-(7/8/9-(non)substituted-3-oxo-1-thia-4-azaspiro[4.4]non/[4.5]dec-4-yl)-1H-indole-2-carboxamide derivatives and their subsequent testing for antibacterial activity is described in this paper. 4-Sulfamoylbenzenediazonium chloride was synthesized from diazotization of sulfanilamide and sodium nitrite in the presence of HCl and was further allowed to condense with ethyl 2-benzylacetoacetate to produce ethyl 2-benzyl-2-(4-sulfamoylphenyl)hydrazonoacetate. This compound was cyclized to ethyl 5-sulfamoyl-3-phenyl-1H-indole-2-carboxylate employing the Fischer-indole procedure. The reaction of ethyl 5-sulfamoyl-3-phenyl-1H-indole-2-carboxylate with hydrazine hydrate yielded sulfamoyl-3-phenyl-1H-indole-2-carbohydrazide. Through a cyclization process, the spirothiazolidinone derivatives were obtained from the reaction of suitable cyclic ketones with 5-sulfamoyl-3-phenyl-1H-indole-2-carbohydrazide in the presence of thioglycolic acid/thiolactic acid. Structural elucidation of the novel compounds was achieved with the help of UV, IR,H-1 NMR, HSQC, ESI-MS, and as well as elemental analysis. Among all the synthesized compounds tested, four compounds displayed the most promising antibacterial activity. The influence of the substituents and their positions on the antibacterial activity was evaluated. [GRAPHICS] .

Indole alkaloids with self-activated sp(2) C-H bond from Alstonia scholaris

Alstoniascholarines T (1) and U (2), two novel monoterpenoid indole alkaloids from Alstonia scholaris, enabled an unexpected deuteration via activation of the sp(2) C-H bond without any catalysts under room temperature. Structurally, alkaloid 1 represented the rare nor-C-17 strychnan indole, and compound 2 possessing highly modified strychnan skeleton with an additional furan ring between C-16/19. This finding presented the detailed description of natural products with sp(2) C-H self activation and deuteration, which may shed a light on the C – H functionalization blocked by the expensive metal catalysts and/or rather harsh reaction conditions.

Oleanolic acid indole derivatives as novel alpha-glucosidase inhibitors: Synthesis, biological evaluation, and mechanistic analysis

Research efforts have been directed to the development of oleanolic acid (OA) based alpha-glucosidase inhibitors and various OA derivatives showed improved anti-alpha-glucosidase activity. However, the inhibitory effects of indole infused OA derivatives on alpha-glucosidase is unknown. Herein, we synthesized a series of indole-OA (2a-2o) and -OA methyl ester (3a-3 1) derivatives with various electron withdrawing groups inducted to indole benzene ring and evaluated their anti-alpha-glucosidase activity. Indole OA derivatives (2a-2o) exhibited superior alpha-glucosidase inhibitory effects as compared to OA methyl ester derivatives (3a-31) and OA (with IC50 values of 4.02 mu M-5.30 mu M v.s. over 10 mu M and 5.52 mu M, respectively). In addition, mechanistic studies using biochemical (kinetic assay), biophysical (circular dichroism), and computational (docking) methods revealed that OA-indole derivatives (2a and 2f) are mixed type of alpha-glucosidase inhibitors and their inhibitory effects were attributed to their capacity of forming the ligand-enzyme complex with alpha-glucosidase enzyme. Findings from this study support that OA indole derivatives are promising alpha-glucosidase inhibitors as a potential management of diabetes mellitus.
