In recent years, several organocatalytic asymmetric hydroarylations of activated, electron-poor olefins with activated, electron-rich arenes have been described. In contrast, only a few approaches that can handle unactivated, electronically neutral olefins have been reported and invariably require transition metal catalysts. Here we show how an efficient and highly enantioselective catalytic asymmetric intramolecular hydroarylation of aliphatic and aromatic olefins with indoles can be realized using strong and confined IDPi Bronsted acid catalysts. This unprecedented transformation is enabled by tertiary carbocation formation and establishes quaternary stereogenic centers in excellent enantioselectivity and with a broad substrate scope that includes an aliphatic iodide, an azide, and an alkyl boronate, which can be further elaborated into bioactive molecules.

Histamine acts through four different receptors (H1R-H4R), the H3R and H4R being the most explored in the last years as drug targets. The H3R is a potential target to treat narcolepsy, Parkinson’s disease, epilepsy, schizophrenia and several other CNS-related conditions, while H4R blockade leads to anti-inflammatory and immunomodulatory effects. Our group has been exploring the dihydrobenzofuranyl-piperazines (LINS01 series) as human H3R/H4R ligands as potential drug candidates. In the present study, a set of 12 compounds were synthesized from adequate (dihydro)benzofuran synthons through simple reactions with corresponding piperazines, giving moderate to high yields. Four compounds (1b, 1f, 1g and 1h) showed high hH(3)R affinity (pK(i) > 7), compound 1h being the most potent (pK(i) 8.4), and compound if showed the best efficiency (pKi 8.2, LE 0.53, LLE 5.85). BRET-based assays monitoring G alpha(i) activity indicated that the compounds are potent antagonists. Only one compound (2c, pK(i) 7.1) presented high affinity for hH(4)R. In contrast to what was observed for hH(3)R, it showed partial agonist activity. Docking experiments indicated that bulky substituents occupy a hydrophobic pocket in hH(3)R, while the N-allyl group forms favorable interactions with hydrophobic residues in the TM2, 3 and 7, increasing the selectivity towards hH(3)R. Additionally, the importance of the indole NH in the interaction with Glu5.46 from hH(4)R was confirmed by the modeling results, explaining the affinity and agonistic activity of compound 2c. The data reported in this work represent important findings for the rational design of future compounds for hH(3)R and hH(4)R.

Herbivore-induced plant volatiles (HIPVs) can mediate tritrophic interactions by attracting natural enemies of insect herbivores such as predators and parasitoids. Whether HIPVs can also mediate tritrophic interactions by influencing the attractiveness of the herbivores themselves remains unknown. We explored this question by studying the role of indole, a common HIPV in the plant kingdom. We found that herbivory-induced indole increases the recruitment of the solitary endoparasitoid Microplitis rufiventris to maize plants that are induced by Spodoptera littoralis caterpillars. Surprisingly, however, indole reduces parasitoid recruitment when the caterpillars themselves are present on the plants. Further experiments revealed that indole exposure renders S. littoralis caterpillars unattractive to M. rufiventris, leading to an overall reduction in attractiveness of plant-herbivore complexes. Furthermore, indole increases S. littoralis resistance and decreases M. rufiventris parasitization success. S. littoralis caterpillars are repelled by indole in the absence of M. rufiventris but specifically stop avoiding the volatile in the presence of the parasitoid. Our study shows how an HIPV can undermine tritrophic interactions by reducing the suitability and attractiveness of caterpillars to parasitoids.

Tissue culture has been widely used for the propagation of papaya (Carica papaya L.). Generally, agar-based media supplemented with the appropriate amount of indole-3-butyric acid (IBA) is used for the in-vitro rooting and root elongation of the papaya explants. However, it is usually resulted in a difficulty in adventitious root (AR) formation and turns into callus formation. The AR formation was influenced by miscellaneous factors, however little is known of the related regulative mechanisms. In this study, RNA-seq was performed on samples collected from leaf-inoculation (LI) and stem-inoculation (SI) GZY6 shoot explants to reveal their different rooting phenotypes. Here, we found that the ARs were induced from in GZY6 (79.17%), GZG4 (63.33%), and GZM26 (37.23%) hermaphroditic papaya shoot explants obtained by LI method after 2 weeks of culture in root-induction medium, but calli were formed rather than AR from the explants obtained by SI method in root-induction medium. The SI and LI shoot explant samples of GZY6 genotypes (the rooting percentage was highest in the three genotypes) were used for the transcriptomic analyses. A total of 2498 differentially expressed genes (DEGs) were identified in the LI vs. SI samples and annotated into 73 Gene ontology (GO) terms. The GO analysis revealed that oxidative-stress, defense-response, and stimulus-response GO terms were significantly different between the LI and SI shoot explants and that the genes are involved in anaerobic respiration and reactive oxygen species (ROS) metabolism pathways. Twelve selected anaerobic and ROS metabolic pathways-related DEGs were used to validate the RNA-seq data by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The activity of superoxide dismutase (SOD) and peroxidase (POD) and the concentration of hydrogen peroxide (H2O2) increased in the SI explants. ARs formation and development were significantly higher in the SI explants in perlite medium than in agar medium, when both were not supplemented with IBA. Papaya shoot explants absolutely formed ARs in peat medium after stem bases dipping in 1 mg mL(-1) IBA for 3 s. Our results indicate that the root-induction medium supplemented with agar and IBA would be mostly limited AR emergence and induced callus formation in SI explants, respectively. This study provides basic data for establishing a healthy and functional rooting system for in vitro papaya propagation.

The first total synthesis of the caged monoterpene indole alkaloid cymoside is reported. This natural product displays a unique hexacyclic-fused skeleton whose biosynthesis implies an early oxidative cyclization of strictosidine. Our approach to the furo[3,2-b]indoline framework relied on an unprecedented biomimetic sequence which started by the diastereoselective oxidation of the indole ring into a hydroxyindolenine which triggered the addition of an enol ether and was followed by the trapping of an oxocarbenium intermediate.

A series of novel indole-based oxalamide and aminoacetamide derivatives were designed, synthesized, and evaluated for antiproliferative activities. Preliminary results revealed that compound 8g exhibited significant antiproliferative effect against PC-3, HeLa and HCT-116 cell lines. Flow cytometric analysis of the cell cycle demonstrated the compound 8g induced the cell cycle arrest at G2/M phase in HeLa cell lines. Immunocytochemistry revealed loss of intact microtubule structure in cells treated with 8g and inhibition of tubulin polymerization. Additionally, molecular docking analysis suggested that 8g formed stable interactions in the colchicine-binding site of tubulin. These preliminary results demonstrated that a new class of novel indole-based oxalamide and aminoacetamide derivatives described in the investigation could be developed as potential scaffolds to new anticancer agents.

PEST rich protein sequences are intrinsically disordered and serve as degradation hotspots in eukaryotic cells. The structure of PEST degrons in proteins and their mechanism of action remain poorly understood. Deregulation or overexpression of human transcription factor c-Myc causes cancer. The PEST region in c-Myc is implicated for its rapid degradation. Here, we investigate how the structure of 77-residue PEST fragment of c-Myc and its mutant (M1, Trp inserted) are affected by the formation of a covalent dimer. DLS and size exclusion data indicated a similar to 30% increase in Stokes radius upon the formation of the dimer. CD showed an increase in helix and strand content with dimer formation in both Wt and mutant. However, counterintuitively, Trp fluorescence anisotropy decay was marginally faster in the dimer compared to monomer. This anomaly was traced to Trp-Trp Forster resonance energy homotransfer in M1 dimer, suggesting close interaction between two chains in the dimer. Our data suggest that indole rings in the PEST M1 dimer are no further than 24 A apart. These results may hold the key to higher stability of c-Myc in tumours and the poorly understood physiological role of c-Myc oligomer in cells.
