The synthesis of 3,3-dimethyl-2-(1-aryl-1H-pyrazol-4-yl)-3H-indoles

2,3,3-Trimethylindolenine and 5-chloro-2,3,3-trimethylindolenine were converted into beta-diformyl compounds by the action of the Vilsmeier reagent at 50 C. The dialdehydes reacted with various arylhydrazines and 2-pyridylhydrazine to produce mono-hydrazones as mixtures of cis and trans isomers. Heating the hydrazones in refluxing ethanol produced 3,3-dimethyl-2-(1-aryl-1H-pyrazol-4-yl)-3H-indoles in excellent yields. Reaction of the beta-diformyl compounds with hydrazine itself led directly to 3,3-dimethyl-2-(pyrazol-4-yl)-3H-indoles.

Green synthesis of predominant (1 1 1) facet CuO nanoparticles: Heterogeneous and recyclable catalyst for N-arylation of indoles

Well faceted CuO nanoparticles were synthesized by thermal-assisted green strategy at reflux temperature in a short period of time. A possible growth mechanism of such highly faceted nanostructures based on typical biomolecule-crystal interactions in aqueous solution is tentatively proposed. The large surface area (223.36 m2/g) and rich exposed active sites are expected to endow such nanostructures with excellent performances in catalysis as demonstrated here for remarkable catalytic activity with respect to the N-arylation of indoles. Nanoparticles were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Both the activity and selectivity of the N-arylation reactions could be tuned by varying the concentration of CuO nanoparticles. Nanoparticles catalyst were recycled and reused for further catalytic reactions with minimal loss in activity. A variety of indole derivatives afforded corresponding N-arylation product with excellent yields (up to 98%).

Identification of the binding modes of N-phenylphthalimides inhibiting bacterial thymidylate synthase through X-ray crystallography screening

To identify specific bacterial thymidylate synthase (TS) inhibitors, we exploited phenolphthalein (PTH), which inhibits both bacterial and human enzymes. The X-ray crystal structure of Lactobacillus casei TS (LcTS) that binds PTH showed multiple binding modes of the inhibitor, which prevented a classical structure-based drug design approach. To overcome this issue, we synthesized two phthalimidic libraries that were tested against TS enzymes and then we performed X-ray crystallographic screening of the active compounds. Compounds 6A, 8A, and 12A showed 40-fold higher affinity for bacterial TS than human TS. The X-ray crystallographic screening characterized the binding mode of six inhibitors in complexes with LcTS. Of these, 20A, 23A, and 24A showed a common unique binding mode, whereas 8A showed a different, unique binding mode. A comparative analysis of the LcTS X-ray complexes that were obtained with the pathogenic TS enabled the selection of compounds 8A and 23A as specific compounds and starting points to be exploited for the specific inhibition of pathogen enzymes.

Synthesis and evaluation of carbocyanine dyes as PRMT inhibitors and imaging agents

Protein arginine methylation regulates multiple biological processes. Deregulation of protein arginine methyltransferase (PRMT) activities has been observed in many disease phenotypes. Small molecule probes that target PRMTs with strong affinity and selectivity can be used as valuable tools to dissect biological mechanisms of arginine methylation and establish the role of PRMT proteins in a disease process. In this work, we report synthesis and evaluation of a class of carbocyanine compounds containing indolium, benz[e]indolium or benz[c,d]indolium heterocyclic moieties that bind to the predominant arginine methyltransferase PRMT1 and inhibit its methyltransferase activity at low micromolar potencies. In particular, the developed molecules have long wavelength colorimetric and fluorometric photoactivities, which can be used for optical and near-infrared fluorescence imaging in cells or biological tissues. Together, these new chemical probes have potential application in PRMT studies both as enzyme inhibitors and as fluorescent dyes for microscope imaging.

The Selective N-Functionalization of Indoles via aza-Michael Addition in the Ligand Sphere of a Chiral Nickel(II) Complex: Asymmetric Synthesis of (S)-1H-Indole-Alanine Derivatives

The selective addition of electrophilic C=C double bonds to the N?H bond of indoles is a challenging task due to the high nucleophilicity of indoles at their C3-position. Herein, we report the successful selective intermolecular N-functionalization of various indoles via aza-Michael addition of C=C double bond of a dehydroalanine Schiff base, which takes place in the ligand sphere of a chiral NiII complex in the presence of sodium hydride. The resulting hydroaminated NiII complexes were isolated in 55?82 % yields with excellent diastereoselectivity (dr > 99:1) (8 examples). And the actual products of interest, namely (S)-2-amino-3-(1H-indol-1-yl)propanoic acids, were subsequently released from the NiII complexes via aqueous HCl treatment of the NiII complexes and isolated with excellent enantioselectivity (> 99 % ee). The chiral auxiliary [(S)-BPB = (S)-2-(N-benzylprolyl)aminobenzophenone] and NiII ions can be easily recovered after the acidic complex cleavage step and reused for the synthesis of the starting NiII complex. Moreover, the indole?s preference for nucleophilic attack via its N1- over its C3-position was rationalized by DFT calculations.
