Experimental and Theoretical Photoemission Study of Indole and Its Derivatives in the Gas Phase

The valence and core-level photoelectron spectra of gaseous indole, 2,3-dihydro-7-azaindole, and 3-formylindole have been investigated using VUV and soft X-ray radiation supported by both an ab initio electron propagator and density functional theory calculations. Three methods were used to calculate the outer valence band photoemission spectra: outer valence Green function, partial third order, and renormalized partial third order. While all gave an acceptable description of the valence spectra, the last method yielded very accurate agreement, especially for indole and 3-formylindole. The carbon, nitrogen, and oxygen is core-level spectra of these heterocycles were measured and assigned. The double ionization appearance potential for indole has been determined to be 21.8 +/- 0.2 eV by C is and N is Auger photoelectron spectroscopy. Theoretical analysis identifies the doubly ionized states as a band consisting of two overlapping singlet states and one triplet state with dominant configurations corresponding to holes in the two uppermost molecular orbitals. One of the singlet states and the triplet state can be described as consisting largely of a single configuration, but other doubly ionized states are heavily mixed by configuration interactions. This work provides full assignment of the relative binding energies of the core level features and an analysis of the electronic structure of substituted indoles in comparison with the parent indole.

Design, synthesis, antifungal activity, and QM/MM docking study of two azole derivatives with indole ring

Systemic candidiasis is a major health issue for immunocompromised individuals due to the increase in drug-resistance among Candida spp., which are prevalent pathogenic fungi responsible for many types of fungal infections. Azoles are among the most preferred antifungal class for systemic candidiasis with broad antifungal spectrum and systemic availability. In this study, we synthesized and tested antifungal effects of two new indole derivatives to investigate the impact of indole on the activity of azole antifungal compounds and to find potent derivatives against Candida spp. including resistant strains and biofilms. 1-(4-Chlorophenyl)-2-(1H-imidazol-1-yl)ethanol 1H-indole-2-carboxylate (4a) showed excellent antifungal profile with several times more potent activity against the tested species including a fluconazole-resistant C. tropicalis isolate. The minimum inhibitory concentration (MIC) of 4a was 0.03125 mu g/ml against C. albicans, which was 0.5 mu g/ml for fluconazole. The compound also showed promising biofilm inhibitory effect compared to amphotericin B. The importance of indole was demonstrated through molecular docking studies with the structure of C. albicans CYP51, the established target of azole antifungals, using different protocols. QM/MM docking approach yielded excellent results and accuracy, especially regarding metal interactions. As a result, indole could be a very useful fragment to design new and highly potent antifungal compounds in azole structure.

CHARACTERISTICS OF INDOLE AEROBIC DEGRADATION SLUDGE REINFORCE TRAINING AND THE RESEARCH OF DEGRADATION EFFICIENCY

To improve the treatment effect in the pharmaceutical wastewater in the biochemical system, the experiment domesticated efficient aerobic activated sludge to deal with wastewater deeply. In the presence of glucose co-matrix, indole was used as the characteristic pollutant to acclimate aerobic activated sludge by increasing pollutant concentration. The degradation characteristics and microbial characteristics during training were studied. The experimental results showed that indole could inhibit the growth of microorganisms in activated sludge, but after 2 months of intensive culture, activated sludge could adapt to the environment in which indole was the only carbon source. The bacteria species in the sludge were mainly Comamonas (34.18%) and Acinetobacter (15.45%), which could treat indole with a concentration of 200mg/L, the degradation efficiency was increased from 80% to more than 98.6%, and the SOUR value was stable at more than 7.61 mgO(2)/g MLSS.h, which was suitable for application in advanced treatment engineering of indole-containing pharmaceutical wastewater.

Salt-tolerant plant growth-promoting Bacillus pumilus strain JPVS11 to enhance plant growth attributes of rice and improve soil health under salinity stress

Rice (Oryza sativa L.) growth and productivity has been negatively affected due to high soil salinity. However, some salt-tolerant plant growth-promoting bacteria (ST-PGPB) enhance crop growth and reduce the negative impacts of salt stress through regulation of some biochemical, physiological, and molecular features. Total thirty six ST-PGPB were isolated from sodic soil of eastern Uttar Pradesh, India, and screened for salt tolerance at different salt (NaCl) concentrations up to 2000 millimolar (mM). Out of thirty-six, thirteen strains indicated better growth and plant growth properties (PGPs) in NaCl amended medium. Among thirteen, one most effective Bacillus pumilus strain JPVS11 was molecularly characterized, which showed potential PGPs, such as indole-3acetic acid (IAA),1-aminocyclo propane-1-carboxylicacid (ACC) deaminase activity, P-solubilization, proline accumulation and exopolysaccharides (EPS) production at different concentrations of NaCl (0 -1200 mM). Pot experiment was conducted on rice (Variety CSR46) at different NaCl concentrations (0, 50, 100, 200, and 300 mM) with and without inoculation of Bacillus pumilus strain JPVS11. At elevated concentrations of NaCl, the adverse effects on chlorophyll content, carotenoids, antioxidant activity was recorded in non-inoculated (only NaCl) plants. However, inoculation of Bacillus pumilus strain JPVS11 showed positive adaption and improve growth performance of rice as compared to non-inoculated in similar conditions. A significant (P < 0.05) enhancement plant height (12.90-26.48%), root length (9.55-23.09%), chlorophyll content (10.13-27.24%), carotenoids (8.38-25.44%), plant fresh weight (12.33-25.59%), and dry weight (8.66-30.89%) were recorded from 50 to 300 mM NaCl concentration in inoculated plants as compared to non-inoculated. Moreover, the plants inoculated with Bacillus pumilus strain JPVS11showed improvement in antioxidant enzyme activities of catalase (15.14-32.91%) and superoxide dismutase (8.68-26.61%). Besides, the significant improvement in soil enzyme activities, such as alkaline phosphatase (18.37-53.51%), acid phosphatase (28.42-45.99%), urease (14.77-47.84%), and beta-glucosidase (25.21-56.12%) were recorded in inoculated pots as compared to non inoculated. These results suggest that Bacillus pumilus strain JPVS11 is a potential ST-PGPB for promoting plant growth attributes, soil enzyme activities, microbial counts, and mitigating the deleterious effects of salinity in rice.

A unified strategy to reverse-prenylated indole alkaloids: total syntheses of preparaherquamide, premalbrancheamide, and (+)-VM-55599

A full account of our studies toward reverse-prenylated indole alkaloids that contain a bicyclo[2.2.2]core is described. A divergent route is reported which has resulted in the synthesis of preparaherquamide, (+)-VM-55599, and premalbrancheamide. An intramolecular Dieckmann cyclization between an enolate and isocyanate was used to forge the bicyclo[2.2.2]diazaoctane core that is characteristic of these molecules. The pentacyclic indole scaffold was constructed through a one-pot Hofmann rearrangement followed by Fischer indole synthesis. The utilization of our previously reported indole peripheral functionalization strategy also led to natural products including malbrancheamides B, C, stephacidin A, notoamides F, I and R, aspergamide B, and waikialoid A. Ultimately, the divergent route that we devised provided access to a wide range of prenylated indole alkaloids that are differently substituted on the cyclic amine core.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 948-65-2. Product Details of 948-65-2.

Synthesis and cytotoxicity evaluation of olivacine-indole hybrids tethered by alkyl linkers

In this work, eleven new derivatives were prepared of the alkaloid olivacine (1), which was isolated from the bark of Aspidosperma australe. These compounds (7a-k) are hybrids of olivacine and indoles or carbazole, tethered by alkyl chains of variable lengths (C-4, C-5 or C-6). Compounds 7a-k showed increased cytotoxicity towards a panel of four cell lines. The subcellular localization of olivacine and of the synthetic derivatives was studied by fluorescence microscopy. The cycles of K562 cells exposed to olivacine or compounds 7a-k were analysed by flow cytometry, and showed, for some of the new derivatives, a different profile of cell distribution among the phases of the cycle when compared to olivacine, which is indicative of lysosomal apoptosis.
