Development of electrochemical and optoelectronic performance of new 7-{[1H-indol-3-ylmethylidene]amino}-4-methyl-2H-chromen-2-one dye

A new 7-{[1H-indol-3-ylmethylidene]amino}-4-methyl-2H-chromen-2-one dye (3) was synthesized by the reaction of 7-amino-4-methyl coumarin with indole-3-carbaldehyde in EtOH using GAA as a catalyst. The photophysical properties of the synthesized compound were studied using UV-visible and photoluminescence spectrophotometer. Redox onset potential for the dye compound was recorded through a cyclic voltammogram (CV), which aids to calculate the highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) values. The experimental and theoretical HOMO-LUMO values were calculated using the density functional theory (DFT). Moreover, the I-V characteristics were evaluated by two-sense Keithley source in dark and light medium by using a mercury lamp as a light source. The results of the I-V study showed that the compound (3) possesses good light-absorbing capability with a high molar absorption extinction coefficient (0.80 x 10(-5) epsilon). Therefore, the I-V characteristics suggest the efficiency of obtained dye for photovoltaic uses.

Transition-Metal-Free Synthesis of 1,2-Disubstituted Indoles

Herein, we report a new transition-metal-free robust and cost-effective method for synthesis of 1,2-disubstituted indoles from easily available unactivated (i.e. without EWG, PPh3 or SiR3 groups) tertiary amides. Scope of synthetic applicability of the presented protocol was shown on 23 examples of 1,2-disubstituted indoles with different substitution patterns obtained in good to excellent yields. The reported method turned out to be especially effective for synthesis of N-arylated 2-CF3-indoles. Moreover, this approach can be performed in a one-pot two-step manner directly from commercially available secondary amines. Mechanistic studies showed that acyl transfer might be an important step in the course of the reaction. Viability of the presented approach for benzofurans and benzothiophenes synthesis was also discussed.

Meta-topolin and liquid medium enhanced in vitro regeneration in Scaevola taccada (Gaertn.) Roxb

Scaevola taccada (Gaertn.) Roxb. is a hemi-sclerophyllous littoral shrub of the family Goodeniaceae. It is a salt-tolerant plant and used in soil reclamation and coastal landscaping programs to control beach erosion. The present article reports a reproducible in vitro regeneration system using meta-topolin (mT) through liquid medium employing nodal segment cultures. The highest number of axillary shoots (5.8 +/- 0.29) was differentiated on Murashige and Skoog’s (MS) medium containing meta-topolin (1.5 mg L-1). The amplification of shoots (49.8 +/- 0.37) and fresh growth was achieved by recurrent subcultures on liquid MS medium supplemented with 0.25 mg L(-1)mT and 0.15 mg L-1 indole-3-acetic acid (IAA) in the presence of additives (50 mg L-1 ascorbic acid + 25 mg L-1 citric acid, adenine sulphate and l-arginine). Rooting and acclimatization was simultaneously achieved using concurrent ex vitro rooting and acclimatization (CEVRA) technique by pulse treating the shoot base with 300 mg L-1 IBA for 5 min. The in vitro developed shoots represented a maximum percentage (100%) of rooting in autoclaved soilrite in a greenhouse. After 2 mo, the plantlets were established in the field with cent percentage survival success. The genetic fidelity analysis using inter simple sequence repeats (ISSR) DNA molecular markers developed maximum of 55 monomorphic bands and revealed the genetic homogeneity of in vitro regenerated plantlets with the mother plant.

A Facile Approach to 3,4-Oxepino-Fused Tricyclic Indoles from MBH-Acetates of Acetylenic Aldehydes via Successive Allylic Substitution/Intramolecular [3+2] Annulation(dagger)

Herein, we present our findings on the synthesis of 3,4-oxepino-fused indoles by a two-step reaction sequence involving an initial allylic substitution followed by Rh(III)-catalyzed intramolecular [3+2] annulation via C-H activation starting from Morita-Baylis-Hillman (MBH) acetates of acetylenic aldehydes. The strategy is amenable to broad range of MBH acetates providing a facile access to 3,4-oxepino-fused indoles in good yield.

Novel effective antibacterial small-molecules against Staphylococcus and Enterococcus strains

Background: Resistance developments against established antibiotics are an emerging problem for antibacterial therapies. Novel antibiotics are urgently needed. Materials & methods: We developed novel small-molecule antibacterials which are easily accessible in a simple one-pot synthesis. The central cyclopentaindole core is substituted with two indole residues. Various indole and cyclopentane substituents have been introduced. Additionally, first indole substituted propene compounds as ring-open variants of the cyclopentaindoles have been yielded and evaluated as antibacterials against Staphylococcus aureus and Enterococcus strains. Results: Most effective compounds have been those with a bromo cyclopentane and a chloro indole substitution. First lead compounds were identified with promising activities similar to that observed in vitro for last resort antibiotics, so that the novel compounds enriche the pool of perspective small-molecule antibacterial drug candidates.

Targeting the gut microbial metabolic pathway with small molecules decreases uremic toxin production

Uremic toxins are a class of toxins that accumulate in patients with chronic kidney disease (CKD). Indoxyl sulfate (IS), a typical uremic toxin, is not efficiently removed by hemodialysis. Modulation of IS production in the gut microbiota may be a promising strategy for decreasing IS concentration, thus, delaying CKD progression. In the present study, we identified isoquercitrin (ISO) as a natural product that can perturb microbiota-mediated indole production without directly inhibiting the growth of microbes or the indole-synthesizing enzyme TnaA. ISO inhibits the establishment of H proton potential by regulating the gut bacteria electron transport chain, thereby inhibiting the transport of tryptophan and further reducing indole biosynthesis. This non-microbiocidal mechanism may enable ISO to be used as a therapeutic tool, specifically against pathologies triggered by the accumulation of the microbial-produced toxin IS, as in CKD. Herein, we have shown that it is possible to inhibit gut microbial indole production using natural components. Therefore, targeting the uremic toxin metabolic pathway in gut bacteria may be a promising strategy to control host uremic toxin production.

Longitudinal relationship of amino acids and indole metabolites with long-term body mass index and cardiometabolic risk markers in young individuals

Amino acid metabolites in biofluids are associated with high body mass index (BMI) and cardiometabolic abnormalities. However, prospective investigations regarding these associations are few, particularly among young individuals. Moreover, little is presently known about the impact of long-term high BMI. Using data from the DOrtmund Nutritional and Anthropometric Longitudinally Designed study (111 males and 107 females), we prospectively investigated relations between repeatedly measured urinary levels of 33 metabolites and (1) previously identified long-term BMI trajectory groups from childhood into late adolescence and (2) cardiometabolic risk markers in late adolescence-young adulthood, in sex-specific linear mixed regression models. Males with long-term overweight had lower indole-3-acetic acid when compared to others. Further, methionine, isoleucine, tryptophan, xanthurenic acid, and indole-3-carboxaldehyde were negatively associated with C-reactive protein (CRP), but 5-hydroxyindole-3-acetic acid was positively associated with CRP. No associations were observed in females. Long-term overweight from childhood into late adolescence is associated with decreased urinary levels of gut bacteria-derived indole-3-acetic acid, and several urinary amino acids, including gut bacteria-derived indole-3-carboxaldehyde are associated with elevated CRP later on in life. Taken together, our data suggest that indole metabolites, and their gut bacteria producers play potentially important roles in overweight-related inflammation.

Direct Preparation of Indole Hemiaminals through Organocatalytic Nucleophilic Addition of Indole to Aldehydes

Hemiaminals are common in natural products as well as bio-active compounds. Hemiaminals with an indole moiety are particularly attractive due to the significant bioactivity of indoles. Herein, we reported an efficient organocatalyzed indole N-1 nucleophilic addition of alpha-oxoaldehydes to deliver various indole hemiaminals in good yields (up to 92%) and excellent regioselectivities with DABCO or triethylamine as the catalyst. The method is characterized by mild reaction conditions, widely available reagents, and general substrate scope, and it is also applicable to late-stage transformations without affecting the hemiaminal group. In addition, we carried out this reaction in an enantioselective fashion in good yields and high ee values with two general substrates.

Sub-minimum inhibitory concentration ceftazidime inhibits Escherichia coli biofilm formation by influencing the levels of the ibpA gene and extracellular indole

Escherichia coli is a common pathogen of bacterial biofilm infections. Sub-minimum inhibitory concentration ceftazidime (sub-MIC CAZ) could inhibit the biofilm formation of E. coli. Deletion of the ibpAB genes could increase the extracellular indole concentration of E. coli and then inhibit biofilm formation. Therefore, we speculated that sub-MIC CAZ might inhibit biofilm formation via ibpAB. In this study, the results showed that sub-MIC CAZ could significantly inhibit biofilm formation, swimming motility and the expression of the ibpA gene, while it could increase the expression of tnaA gene and extracellular indole concentration. Knockout of the ibpA gene resulted in a decrease in biofilm formation and swimming motility and an increase in the indole concentration. When treated with sub-MIC CAZ, the tnaA gene expression, indole concentration, biofilm formation and swimming motility of MG1655 ?ibpA were similar to those of the control group. The results indicated that sub-MIC CAZ might inhibit the biofilm formation of E. coli by increasing the extracellular indole concentration and downregulating the ibpA gene.
