High-quality freestanding flexible poly(5-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-1H-indole) film: Electrosyntheses, characterization, and optical properties

The electron-donating substituted indole is generally difficult to be polymerized into high-quality film. The electrochemical polymerization of the electron-donating 3,4-ethylenedioxythiophene (EDOT)-monosubstituted indole may be a challenge. Herein, we designed and synthesized a novel fluorescent comonomer based on the combination of indole and EDOT groups, namely, 5-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-1H-indole (EDTI), and subsequently electrodeposited into flawless freestanding flexible poly(5-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-1H-indole) (PEDTI) film with a resistance of 60 M omega/cm in CH2Cl2 containing 0.1 M Bu4NBF4. Electrochemical results showed that the oxidation onset potential of EDTI was at 0.8 V vs Ag/AgCl, which was lower than those of indole (0.96 V vs Ag/AgCl) and EDOT (1.35 V vs Ag/AgCl). FTIR spectra indicated that the polymerization of EDTI occurred at the 5-position on thiophene ring and 2,3-positions on indole ring, forming the crosslinking polymer film. The colors of as-prepared PEDTI could switch reversibly from purple to brown under applied potentials of 1.3 and -1.3 V, which were distinctly different from those of polyindole, poly(3,4-ethylenedioxythiophene) (PEDOT), and poly(EDOT-bis-substituted indole) (PETI). Fluorescence spectral studies revealed that the comonomer and corresponding polymer were good blue-green light emitters. These results implied that PEDTI had potential applications for photoelectric devices such as electrochromic devices, light-emitting diodes, and fluorescence sensors. (c) 2018 Wiley Periodicals, Inc.

Spatio-temporally expressed sorbitol transporters cooperatively regulate sorbitol accumulation in pear fruit

Sorbitol is the primary substrate translocated from source to sink in pear species. Among the many sorbitol transporters (SOTs), some are known to be involved in sorbitol accumulation in fruit; however, their particular roles are unclear. In this study, we examined the transcriptome and metabolome of a variety of pear samples from six time points to identify those SOTs. Similar to previous studies, sorbitol and sucrose differed significantly between the leaf and fruit, and sorbitol was consistently observed at higher concentrations at all time points. Interestingly, we found that sorbitol accumulation in pear fruit was cooperatively mediated by SOT3, SOT6/20, SOT19/21, and SOT22. In particular, the up-regulated SOT6/20 and SOT19/21 in fruit under 1 mg L-1 abscisic acid and 10 mg L-1 indole acetic acid treatments, respectively, resulted in an increased sorbitol concentration. In addition, sorbitol concentration showed positive correlations to fructose and glucose concentrations, indicating a role for sorbitol in the determination of fruit sweetness. Together with the deduced process of sugar biosynthesis, transport, conversion, and accumulation in pear, our study provides a foundation for further research into sugar accumulation processes in pear fruit, contributing to the improvement of fruit quality.

Acetylenic Indole-Encapsulated Schiff Bases: Synthesis, In Silico Studies as Potent Antimicrobial Agents, Cytotoxic Evaluation and Synergistic Effects

A family of pharmacophore acetylenic indole-3-carboxaldehyde (3) and acetylenic indole schiff bases (5a-5i) bearing indole framework were synthesized to afford structurally diverse moieties. Acetylenic indole-3-carboxaldehyde was coupled with various amines to furnish the novel scaffolds 5a-5i. These acetylenic indole Schiff bases (AISB) were synthesized in shorter times under microwave irradiation in comparison to classical reaction conditions. AISB were experimentally characterized by using IR, (HNMR)-H-1, (CNMR)-C-13, X ray crystallographic and mass spectrometric methods. The synthesized compounds showed promising anti-bacterial and anti-fungal properties when tested invitro against six bacterial and seven fungal strains. Among these, hybrids 5a, 5c, 5e and 5g were found to be even more potent than the standard drugs and were more influential against the bacterial than the fungal strains. These more potent compounds were then evaluated for their cytotoxicity by MTT assay on Hek293 and HeLa cells. The synergistic effect of bis-acetylenic compound 5g with kanamycin and amphotericin B has also been scrutinized. Further, the structural and electronic properties of the molecules were investigated theoretically by performing density functional theory (DFT).

Synthesis, density functional theory and sensitization of indole dyes

Herein, the two typical anchoring groups are tethered into the indole chromophore and studied their impact on the molecular orbital energy levels and titania sensitization. The synthesized indole derivatives were meticulously characterized. The photophysical and time dependent density functional theory results were revealed that the indole connected rhodanine-3-acetic acid group is an efficient light harvester. The favorable electronic excitation from the highest occupied molecular orbital to the lowest unoccupied molecular orbital indicated that the dye comprised with rhodanine-3-acetic acid could be used as a prospective material for dye-sensitized solar cell applications.

Structure Revisions of the Sponge-Derived Dibrominated Bis-indole Alkaloids, Echinosulfone A and the Echinosulfonic Acids A to D

The structures of the sponge-derived dibrominated bisindole alkaloids, namely, echinosulfone A (2) and the echinosulfonic acids A to D (9-12), have been revised based upon reanalysis of their NMR spectroscopic and MS spectrometric data, comparison of this data with those reported for structurally related compounds, and based on their common biogenesis. The reinterpreted spectroscopic evidence has been corroborated by the total synthesis of the revised structure of echinosulfone A (2). This was achieved by bis-carbonylation at C-3 of the magnesium salt of 6-bromoindole with triphosgene to afford the new dibrominated bis-indole ketone, bis(6-bromo-1H-indol-3-yl)methanone (3), followed by N-sulfonation of one indole moiety to furnish 6-bromo-3-(6-bromo-1H-indole-3-carbonyl)-1H-indole-1-sulfonate (2). The five marine alkaloids corrected herein each contain an indole sulfamate and are all carbon-bridged dibrominated bis-indoles: echinosulfone A (2) is a di(1H-indol-3-yl)methanone, while the echinosulfonic acids A to D (9-12) are methyl 2,2-bis(1H-indol-3-yl) acetates.

Profiles of endogenous ABA, bioactive GAs, IAA and their metabolites in Medicago truncatula Gaertn. non-embryogenic and embryogenic tissues during induction phase in relation to somatic embryo formation

Main conclusionDuring the 3-week-long induction phase, when M. truncatula cells leaf explants from non-embryogenic genotype (M9) and embryogenic variant (M9-10a) were forming the callus, biosynthesis and degradation of ABA, Gas and IAA proceeded at different levels. Induction of embryo formation is related to a lower ABA content, compared to the content of IAA and that of total bioactive GAs.AbstractEndogenous phytohormones are involved in the regulation of zygotic embryogenesis, but their role, especially of ABA, a plant growth inhibitor, in inducing somatic embryogenesis (SE) in angiosperms is still incompletely known. To arrive a better understanding of the ABA role in the process, we analyzed simultaneously and in detail changes in the contents of both ABA and five bioactive GAs (GA(4,) GA(7,) GA(1), GA(3,) GA(6)) and IAA in M. truncatula non-embryogenic M9 (NE) and embryogenic M9-10a (E) genotypes. The initial leaf explants of both genotypes, and particularly NE, contained many times more ABA compared to the total bioactive GAs or IAA. In tissues during the entire 21-day induction all the hormones mentioned and their metabolites or conjugates were present; however, their contents were found to differ between the lines tested. The ABA level in primary explants of NE genotype was more than two times higher than that in E genotype. An even larger difference in the ABA content was found on the last day (day 21) of the induction phase (IP); the ABA content in E callus was over six times lower than in NE callus. In contrast, the IAA and GAs contents in primary explants of both genotypes in relation to ABA were low, but the contents of IAA and GAs exceeded that of ABA in the M9-10a tissues on the last day of IP. It is shown for the first time that endogenous ABA together with endogenous bioactive GAs and IAA is involved in acquisition of embryogenic competence in Medicago truncatula leaf somatic cells. These findings have a strong functional implication as they allow to improve the SE induction protocol.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 112-00-5, in my other articles.
