Alk-1-enesulfonic acids and derivatives (update 2018)

This update covers new information regarding methods for the preparation of alk-1-enesulfonic acids and derivatives and their application in synthesis published since 2004. Aryl ethenesulfonates and aryl vinyl sulfones are a new class of mechanism-based probes of the protein tyrosine phosphatases.[1] Ethenesulfonates and vinyl sulfones inactivate a large variety of protein tyrosine phosphatases in a time- A nd concentration-dependent fashion. This inactivation by Michael addition of the cysteine residue is active-site-directed and irreversible. The relative rates of base-promoted Michael additions to several alk-1-enyl sulfonyl compounds were measured by 1HNMR spectroscopy. Phenyl (E)-3-[(benzyloxycarbonyl)amino]-3-phenylprop-1-ene-1-sulfonate undergoes conjugate addition at a rate ca. 3000-fold higher than that of the corresponding (E)-N-benzyl-3-[(benzyloxycarbonyl) amino]-3-phenylprop-1-ene-1-sulfonamide derivative.[2] The novel alkenesulfonic acid derivative celtisanin (1) has been isolated from the fruits of the tree Celtis australis (Ulmaceae) which grows in the montane and submontane Himalayan regions in India (Scheme 1).[3] The plant is known as traditional medicine for various ailments. The structure of celtisanin has been established using MS and NMR spectroscopy.

Pyrolysis Behaviours of Microalgae Nannochloropsis gaditana

In this study, the pyrolysis behaviours of marine microalgae biomass, Nannochloropsis gaditana, were investigated at three different temperatures (400, 500, 600 C). Experiments were conducted in the presence of N2 with a flow rate of 50?cm3/h using a 1-kg fixed-bed reactor. The effects of pyrolysis conditions such as temperature on product yields were studied. The char, bio-oil, and gaseous samples obtained were analysed for elemental trace metals using inductively coupled plasma atomic emission spectroscopy (ICP-OES) and gas chromatography with mass detection (GC?MS). Raw Nannochloropsis gaditana samples were also analysed by pyrolysis?gas chromatography?mass spectrometry (Py?GC?MS). Mass and energy balances were calculated. The results indicate that the bio-oil from the pyrolysis of Nannochloropsis gaditana under 600 C had the highest heating value (12.6?MJ/kg) and was obtained with the highest efficiency (38?40%). Alkanes and alkenes, such as tetradecane, pentadecane, heptadecene, and octadecene, were identified in the liquid products, and the highest contents of alkanes and alkenes were determined in the bio-oil obtained under 500 C. In these pyrolysis conditions, gaseous products exhibited the highest concentrations of methane (greater than 50% in the maximum range). These properties of the bio-oil and its gaseous products demonstrated that Nannochloropsis gaditana can be used as a renewable energy resource and chemical feedstock. The biochar from all processes contained almost 70% ash and, in this particular case, can be used as, for example, a fertilizer because it does not contain any heavy metals.

Evolution of a thienopyrimidine antitubercular relying on medicinal chemistry and metabolomics insights

The metabolic instability of an antitubercular small molecule CD117 was addressed through iterative alteration of a key sulfide substituent and interrogation of the effect on growth inhibition of cultured Mycobacterium tuberculosis. This process was informed by studies of the intramycobacterial metabolism of CD117 and its inactive carboxylic acid derivative. Isoxazole 4e and thiazole 4m demonstrated significant gains in mouse liver microsomal stability with slight losses in whole-cell activity. This work illustrates the challenges of antitubercular hit evolution, requiring a balance of chemical and biological insights.

Development and therapeutic impact of HDAC6-selective inhibitors

Histone deacetylases (HDAC) play a key role in regulating gene expression by deacetylating histones. Some HDAC isoforms can also modulate the function of nonhistone proteins implicated in regulatory processes, and therefore HDACs are recognized as useful targets for therapeutic purposes. HDAC inhibitors have generated substantial interest as antitumor agents, because they induce various cellular effects, including apoptosis, cell cycle arrest and inhibition of angiogenesis. The nature of cellular response likely depends on the biological context and on the pattern of HDAC isoform inhibition. Various HDAC inhibitors belonging to different structural classes have been developed. Many inhibitors are characterized by a pan-HDAC inhibitory profile. The potential advantages of isoform-selective inhibitors over pan-HDAC inhibitors in terms of efficacy or toxicity remain to be defined. The emerging interest for HDAC6-selective inhibitors is related to the modulation of acetylation of nonhistone regulatory proteins implicated in cancer-relevant processes, including cell migration, metastasis, angiogenesis and stress-response pathways. This review is focused on the recent development of HDAC inhibitors, with particular reference to HDAC6-selective inhibitors, and the efforts and perspectives in optimization of their therapeutic applications.

Photolysis of Antibiotics under Simulated Sunlight Irradiation: Identification of Photoproducts by High-Resolution Mass Spectrometry

There is growing concern regarding the widespread use of antibiotics and their presence in the aqueous environment. Their removal in the water column is mediated by different types of degradation processes for which the mechanisms are still unclear. This research is focused on characterizing the photodegradation kinetics and pathways of two largely employed antibiotics families: sulfonamides (9 SDs) and fluoroquinolones (6 FQs). Degradation percentages and rates were measured in pure water exposed to simulated natural sunlight at a constant irradiance value (500 W m-2) during all the experiments, and the main photoproducts formed were characterized through accurate mass measurement using ultraperformance liquid chromatography-quadrupole-time-of-flight-mass spectrometry (UPLC-QToF-MS). Over 200 different phototransformation products were identified for SDs and FQs, 66% of them, to the best of our knowledge, have not been described before. Their sequential formation and disappearance over the course of the experiments reveals the existence of several pathways for the degradation of target antibiotics. Occurrence of new photoproducts derived from desulfonation and/or denitrification, as well as hydroxylation of photo-oxidized heterocyclic rings, have been identified during photodegradation of SDs, whereas a new pathway yielding oxidation of the benzene ring after the cleavage of the piperazine ring (e.g., CIP product with m/z 280) is described for FQs.

Kinetic investigation of reactions of atomic carbon, C[2p2(3PJ)], with simple nitrogen-containing molecules and aromatic heterocyclic compounds

The reactions of atomic carbon in its electronic ground state, C[2p2(3PJ)], with some simple nitrogen-containing molecules and aromatic heterocyclic compounds have been investigated by time-resolved atomic resonance absorption spectroscopy in the vacuum ultra-violet following the generation of C(23PJ) by the pulsed photolysis of C3O2. Decay profiles for atomic carbon were derived from resonance absorption measurements at lambda = 166 nm (33PJ-23PJ) using repetitive pulsing techniques coupled with signal averaging. Absolute rate data for the collisional removal of C(23PJ) by these gases were obtained as follows: kR (cm3 molecule-1 s-1, 300 K): NH3 < 1.1 ¡Á 10-1, 1-propanamine < 8.2 ¡Á 10-12, 2-methylpyridine = 5.3 ¡À 0.6 ¡Á 10-10, 4-methylpyridine = 5.5 ¡À 0.2 ¡Á 10-10, 1-methylpyrrole = 2.3 ¡À 0.5 ¡Á 10-10, thiazole = 2.9 ¡À 0.2 ¡Á 10-10, oxazole = 2.4 ¡À 0.2 ¡Á 10-10 and isoxazole = 2.2 ¡À 0.3 ¡Á 10-10. The rate data were compared, where possible, with absolute rate data for analogous collision targets reported hitherto and considered within the context of the role of atomic carbon in the interstellar medium.

The Paterno-Buechi reaction-a comprehensive review

The photochemical reaction between an excited state of carbonyl compounds and an alkene to give the oxetane deriving from a cycloaddition reaction (the Paterno-Buechi reaction) is presented. The mechanism of the reaction is discussed on the basis of kinetic, spectroscopic, and theoretical evidence, showing that the reaction can involve both singlet and triplet excited states of the carbonyl compounds, the high probable presence of an exciplex, and the possible presence of electron transfer processes, and when triplet excited carbonyl compounds are involved, the presence of a biradical intermediate is observed. The reactivity of electron-poor and electron-rich alkenes is discussed. Regio- and stereochemical behavior of the reaction are presented showing that, in some cases, very high regio- and stereoselectivities are obtained. The possible theories explaining this behavior are presented. In this field, the stereoselectivity observed, when chiral auxiliaries are used, when the reaction is performed in organized media, and when the presence of a hydroxyl directing effect can be supposed, is presented. The effect of light, temperature, solvent on the reaction is discussed. The possible application of this reaction in organic synthesis is discussed, presenting both previous synthetic schemes where the synthesis of an oxetane is a key step, the possible use of the oxetane in synthesis, and comparing the photochemical approach with the other approaches used to synthesize the oxetane ring.
