Author is Farran, Rajaa; Jouvenot, Damien; Loiseau, Frederique; Chauvin, Jerome; Deronzier, Alain.

A tri-metallic triad based on a [Ru(bpy)3]2+ moiety connected to Fe(II) and Co(III) bis-terpyridine was grafted on an ITO electrode by a stepwise procedure. Under visible light, in the presence of a sacrificial electron donor, the system produces elec. current. The photo-current magnitude is compared to the one generated from a Co(III)-Ru(II) dyad and shows an increase of 40%.

Name: 4-(p-Tolyl)-2,2:6,2-terpyridine. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-(p-Tolyl)-2,2:6,2-terpyridine, is researched, Molecular C22H17N3, CAS is 89972-77-0, about Kinetics and potential well in electrochemical hydrogen evolution by [Co(4-tolyl-tpy)2]2+. Author is Padhi, Sumanta Kumar; Ahmad, Ejaz; Rai, Surabhi.

The ligand 4-tolyl-tpy [4-tolyl-tpy = 2,6-di(pyridin-2-yl)-4-p-tolylpyridine] and the corresponding cobalt complexes like [Co(4-tolyl-tpy)2]Cl2 and [Co(4-tolyl-tpy)2]Br3 has been synthesized and characterized by different spectroscopic and electrochem. methods. The electrochem. studies were carried out in 95:5 (volume/volume) DMF/H2O using acetic acid (AcOH) as a proton source. The faradaic efficiency found to be f = (86 ± 4) % using potential range -1.4 V to -1.7 V vs. SCE for a period of 1 h. The ic/ip value found to be 57.9 for a scan rate of 100 mV s-1, and TOF was calculated to be 652 s-1. The electrocatalytic H2 production by [Co(4-tolyl-tpy)2]2+ complex was also employed in phosphate buffer pH 7, and it shows the Faradaic efficiency of (88 ± 4%) within the overpotential range from -1.2 V to -1.5 V vs. SCE. The TOF of the reaction was found to be 3900 mmol of H2 per mol of catalyst per h. The compare of electrochem. proton reduction, as well as water reduction by [Co(4-tolyl-tpy)2]2+ with the basic scaffold [Co(tpy)2]2+, reveals that it shows higher catalytic activity and have lower overpotential of 150 mV for proton reduction and 100 mV for water reduction Various kinetics and spectroscopic studies are utilized to predict the mechanism for proton reduction The kinetic and mechanistic studies are depicted based on changes in absorbance with the addition of Co(Cp)2, followed by AcOH. The intermediates involved in the kinetic process was analyzed through global fitting and SVD anal. The formation of [CoI(L2)] → [CoIII(H)(L)(2L)] and [CoIII(L)(2L)S] → [CoII(L)2] are faster reactions in comparison to the formation of Co(III)-Hδ-···Hδ+ to evolve hydrogen (Where 2L is bidentate 4-toly-tpy and S = solvent). The pK value was calculated to be 16.5 for Co(III)-H species in DMF generated from CoI species i.e.CoI + H+ ⇄ Co(III)-H.

We have developed a novel class of 2-phosphonate 1,3-dioxolane nucleotide analogs, from which the guanine derivative displayed weak anti-HCMV activity. Further SAR studies led to the identification of both cis and trans guanine derivatives of THF analogs as potent anti-HCMV agents, both in vitro and in vivo, compared to ganciclovir and HPMPC.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 32780-06-6, is researched, SMILESS is O=C1O[C@H](CO)CC1, Molecular C5H8O3Journal, Article, Journal of the American Chemical Society called Stereochemical Elucidation of Streptorubin B, Author is Haynes, Stuart W.; Sydor, Paulina K.; Corre, Christophe; Song, Lijiang; Challis, Gregory L., the main research direction is stereochem streptorubin B Streptomyces enantioselective synthesis.Formula: C5H8O3.

Streptorubin B is a structurally remarkable member of the prodiginine group of antibiotics produced by several actinobacteria, including the model organism Streptomyces coelicolor A3. Transannular strain within the pyrrolophane structure of this mol. causes restricted rotation that gives rise to the possibility of (diastereomeric) atropisomers. Neither the relative nor the absolute stereochem. of streptorubin B is known. NOESY NMR experiments were used to define the relative stereochem. of the major atropisomer of streptorubin B·HCl in solution as anti. We exploited this finding together with our knowledge of streptorubin B biosynthesis in S. coelicolor to determine the absolute stereochem. of the anti atropisomer. 2-Undecylpyrrole stereoselectively labeled with deuterium at C-4′ was synthesized and fed to a mutant of S. coelicolor, which was unable to produce streptorubin B because it was blocked in 2-undecylpyrrole biosynthesis, and in which the genes responsible for the last two steps of streptorubin B biosynthesis were overexpressed. 1H and 2H NMR anal. of the stereoselectively deuterium-labeled streptorubin B·HCl produced by this mutasynthesis strategy allowed us to assign the absolute stereochem. of the major (anti) atropisomer as 7’S. HPLC analyses of streptorubin B isolated from S. coelicolor on a homochiral stationary phase and comparisons with streptorubin B derived from an enantioselective synthesis showed that the natural product consists of an approx. 88:7:5 mixture of the (7’S, anti), (7’S, syn), and (7’R, anti) stereoisomers.

Formula: C10H14N2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: (S)-3-(Piperidin-2-yl)pyridine, is researched, Molecular C10H14N2, CAS is 494-52-0, about Ethylene response factor NtERF91 positively regulates alkaloid accumulations in tobacco (Nicotiana tabacum L.).

Tobacco alkaloid metabolism is regulated by various transcription factors (TFs). Here, we have characterized a non-NIC2 locus gene, Ethylene Response Factor 91 (ERF91), function in regulation of alkaloid accumulation in tobacco. NtERF91 was preferentially expressed in roots and induced by jasmonic acid. Addnl., NtERF91 was able to in vitro bind to the NtPMT2 and NtQPT2 promoters via directly targeting the GCC-box elements and transactivate NtQPT2 gene expression. Ectopic overexpression of NtERF91 not only increased the expression of most nicotine biosynthetic genes, but also altered alkaloid accumulation profile, resulting in dramatically anatabine accumulation. We conclude that NtERF91 plays an overlapped but distinct role in regulating tobacco alkaloid accumulations.
