Reaction of 3-dehydroecdysone with certain n.m.r. solvents.

ABSTRACT: Synthetically prepared 3-dehydroecdysone shows by n.m.r. spectroscopy a mixture of two and three components in 2H2O and [2H4]methanol respectively; only 3-dehydroecdysone is indicated in [2H5]pyridine. Although 3-dehydroecdysone is the sole component in [2H5]pyridine, it represents only 62% and 55% in 2H2O and [2H4]methanol respectively. Evidence indicates that the other component in 2H2O is a 3-[2H2]hydrate of 3-dehydroecdysone, and that in [2H4]methanol the other two components are isomeric [2H3]hemiacetals of 3-dehydroecdysone.

The effects of certain glycols, substituted glycols and related organic solvents on the thermal stability of soluble collagen.

Project description:The effects of a number of related diols, substituted diols and glycerol on the thermal stability of acid-soluble calf skin collagen were investigated. Thermal transition temperatures were determined by optical rotation measurement. Short-chain diols with terminal hydroxyl groups, i.e. ethylene glycol and propane-1,3-diol, stabilized the protein at all accessible concentrations. Stabilization was also observed with glycerol and diethylene glycol. Higher homologues in the diol series produced various effects, as did hydroxyl-group positional isomerism. Monoalkyl substitution of diols progressively lowered the denaturation temperature of collagen. Results are discussed in relation to possible mechanisms of perturbant action.

Madurastatins with Imidazolidinone Rings: Natural Products or Side-Reaction Products from Extraction Solvents?

Project description:Madurastatins are a group of pentapeptides containing an oxazoline moiety, and, in a few cases, an imidazolidinone ring as an additional structural feature. In our search for new potential antiparasitic metabolites from natural sources, we studied the acetone extracts from a culture of Actinomadura sp. CA-135719. The LC/HRMS analysis of this extract identified the presence of the known madurastatins C1 (1), D1 (4), and D2 (5) together with additional members of the family that were identified as the new madurastatins H2 (2) and 33-epi-D1 (3) after isolation and spectroscopic analysis. The planar structures of the new compounds were established by HRMS, ESI-qTOF-MS/MS, and 1D and 2D NMR data, and their absolute configuration was proposed using Marfey's and bioinformatic analyses of the biosynthetic gene cluster (BGC). A revision of the absolute configuration of madurastatins D1 and D2 is proposed. Additionally, madurastatins containing imidazolidinone rings are proved to be artifacts originating during acetone extraction of the bacterial cultures.

Suzuki-Miyaura cross coupling is not an informative reaction to demonstrate the performance of new solvents.

Project description:The development and study of new solvents has become important due to a proliferation of regulations preventing or limiting the use of many conventional solvents. In this work, the suitability of the Suzuki-Miyaura reaction to demonstrate the usefulness of new solvents was evaluated, including Cyrene™, dimethyl isosorbide, ethyl lactate, 2-methyltetrahydrofuran (2-MeTHF), propylene carbonate, and γ-valerolactone (GVL). It was found that the cross coupling is often unaffected by the choice of solvent, and therefore the Suzuki-Miyaura reaction provides limited information regarding the usefulness of any particular solvent for organic synthesis.

The reaction of metallothionein with mercuribenzoate. A dialysis and 113Cd-n.m.r. study.

Project description:Reaction of rat liver cadmium-metallothionein-II(Cd-MT-II) with p-hydroxymercuribenzoate(pHOHgBzO-) causes displacement of bound Cd. When pHOHgBzO- -induced displacement of 109Cd is observed after dialysis of the reaction mixture, the stoichiometry is consistent with stepwise displacement of tetraco-ordinate Cd atoms by non-random entry of reagent into the polynuclear clusters. 113Cd n.m.r. allows direct observation of the effects on bound Cd of stepwise titration of 113Cd-MT-II with pHOHgBzO-. The first equivalent reduces all resonances approximately equally. Subsequently differential reactivity of the protein thiolates towards the reagent gives rise to differential decreases in the 113Cd signal intensities. Resonances previously attributed to a three-metal cluster are lost before those arising from the four-metal cluster. These results are interpreted in terms of current models of the MT structure. They are distinct from the results of reaction of MT with 5,5'-dithiobis-(2-nitrobenzoic acid), which distinguishes between only two classes of thiolates, terminal and bridging. Such different patterns of reactivity of the protein thiolates may underlie a biological activity of this protein.

Development and initial application of a hybridization-independent, DNA-encoded reaction discovery system compatible with organic solvents.

Project description:We have developed and applied an approach to reaction discovery that takes advantage of DNA encoding, DNA-programmed assembly of substrate pairs, in vitro selection, and PCR amplification, yet does not require reaction conditions that support DNA hybridization. This system allows the simultaneous evaluation of >200 potential bond-forming combinations of substrates in a single experiment and can be applied in a range of solvent and temperature conditions. In an initial application, we applied this system to explore Au(III)-mediated chemistry and uncovered a simple, mild method for the selective Markovnikov-type hydroarylation of vinyl arenes and trisubstituted olefins with indoles.

Deep Eutectic Solvents as New Reaction Media to Produce Alkyl-Glycosides Using Alpha-Amylase from Thermotoga maritima.

Project description:Deep Eutectic Solvents (DES) were investigated as new reaction media for the synthesis of alkyl glycosides catalyzed by the thermostable ?-amylase from Thermotoga maritima Amy A. The enzyme was almost completely deactivated when assayed in a series of pure DES, but as cosolvents, DES containing alcohols, sugars, and amides as hydrogen-bond donors (HBD) performed best. A choline chloride:urea based DES was further characterized for the alcoholysis reaction using methanol as a nucleophile. As a cosolvent, this DES increased the hydrolytic and alcoholytic activity of the enzyme at low methanol concentrations, even when both activities drastically dropped when methanol concentration was increased. To explain this phenomenon, variable-temperature, circular dichroism characterization of the protein was conducted, finding that above 60 °C, Amy A underwent large conformational changes not observed in aqueous medium. Thus, 60 °C was set as the temperature limit to carry out alcoholysis reactions. Higher DES contents at this temperature had a detrimental but differential effect on hydrolysis and alcoholysis reactions, thus increasing the alcoholyisis/hydrolysis ratio. To the best of our knowledge, this is the first report on the effect of DES and temperature on an enzyme in which structural studies made it possible to establish the temperature limit for a thermostable enzyme in DES.

Revisiting the Balz-Schiemann Reaction of Aryldiazonium Tetrafluoroborate in Different Solvents under Catalyst- and Additive-Free Conditions.

Project description:The thermal and photochemical Balz-Schiemann reaction in commonly used solvents was revisited under catalyst- and additive-free conditions. The study showed that using low- or non-polar solvents could improve the pyrolysis and photolysis of aryldiazonium tetrafluoroborates, enabling effective fluorination at a low temperature or under visible-light irradiation. PhCl and hexane were exemplified as cheap and reliable solvents for both reactions, providing good to excellent yields of aryl fluorides from the corresponding diazonium tetrafluoroborates. The combination of slight heating with visible-light irradiation was beneficial for the transformation of stable aryldiazonium tetrafluoroborates. Nevertheless, the electronic and steric nature of aryldiazonium tetrafluoroborates still had a pivotal effect on both fluorinations even in these solvents.

Exposure of zebrafish embryos to organic solvents, dimethylformamide and dimethyl sulfoxide

Project description:Current aquatic chemical testing guidelines recognise that solvents can potentially interfere with the organism or environmental conditions of aquatic ecotoxicity tests and therefore recommend concentration limits for their use. These recommendations are based on evidence of adverse solvent effects in apical level tests. The growing importance of sub-apical and chronic endpoints in future test strategies, however, suggests the limits may need re-assessment. To address this concern, microarrays were used to determine the effects of organic solvents, dimethylformamide (DMF) and dimethyl sulfoxide (DMSO), upon the transcriptome of zebrafish (Danio rerio) embryos. Embryos were exposed for 48 h to 0.025 and 0.1 ml/L DMF or DMSO. Effects on survival and development after 24 and 48 h were assessed microscopically with no effects on mortality or morphology. However, analysis of 48-h embryonic RNA revealed large numbers of differentially expressed genes for both solvent at both concentrations. The enrichment of differentially expressed genes was found for metabolic, development and other key biological processes, some of which could be linked to observed morphological effects at higher solvent concentrations. These findings emphasise the need to remove or lower as far as possible, the concentrations of solvent carriers in ecotoxicology tests.

The reaction of iodobenzene-p-sulphonyl chloride (pipsyl chloride) with certain amino acids and peptides, and with insulin.

Project description:1. A system of separation using buffered Celite columns is described that enables the pipsyl derivatives of most of the common amino acids to be separated. 2. The reaction of pipsyl chloride with several amino acids not included in previous studies has been investigated. In particular, knowledge of the acid-soluble pipsyl derivatives of arginine, histidine, lysine, tyrosine and cysteic acid has been extended. 3. Reproducible factors have been obtained that enable corrections to be applied for the breakdown of pipsylamino acids on acid hydrolysis. 4. The reaction of pipsyl chloride with peptides has been studied under various conditions. 5. The extent of the reaction between pipsyl chloride and insulin depends on the nature of the solvent-buffer system, and under the best conditions so far found is about 75% complete. 6. In an Appendix, the separation of pipsylamino acids by thin-layer chromatography is described.
