To improve the efficiency of the photocatalytic decarbonylation of cyclopropenones, the effects of substituents on cyclopropenone were explored. A benzothiophene-substituted aminocyclopropenone exhibited significantly improved decarbonylation efficiency to produce the corresponding ynamine, which worked as a potent dehydration condensation agent. The benzothiophene derivative was applicable to the photocatalytic reaction in the presence of potential excited-state quenchers such as oxygen and anilines. The high catalyst sensitivity would be attributed to the involvement of triplet energy transfer reaction pathway, which was not observed in the reaction with previously reported aminocyclopropenones.

The electrochemical-induced C-H methylthiolation of electron-rich aromatics has been accomplished via a three component cross-coupling strategy. Potassium thiocyanate (KSCN) as both the supporting electrolyte and sulfur source and methanol as the methylation reagent are used. This protocol is versatile for various (hetero)aromatic compounds such as aniline, anisole and indole. The reaction proceeds under mild conditions without any metal catalyst, exogenous oxidant and highly toxic sulfur reagent. Importantly, such an electrochemical-induced methylthiolated reaction could be easily scaled up with good efficiency.

Microplastics (MPs) and nanoplastics (NPs) are ubiquitous and contaminate soil, surface waters, atmospheric aerosol, precipitations, indoor and outdoor environments. However, the occurrence, transformation and fate of NPs in the environment are still unclear. In this work, polystyrene nanoparticles (PS-NPs) are used as a proxy of NPs to study their reactivity and potential impact on atmospheric and surface waters. In particular, the reactivity with hydroxyl radicals (center dot OH) in the aqueous phase is investigated. For the first time, a reactivity constant for the reaction of NPs with center dot OH is measured, strongly dependent on the exposed partide surface area of NPs. Degradation products (short chain carboxylic acids and aromatic compounds), obtained by direct and center dot OH-mediated photolysis of PS-NPs suspensions, are identified by mass spectrometry. Irradiation of a PS-NPs suspension under natural sunlight for 1 year has shown the formation of formic acid and organic compounds similar to those found in riverine and cloud dissolved organic matter, which could contribute significantly to the dissolved organic matter in the aqueous phase.

Currently, due to the HIV latency mechanism, the search continues for effective drugs to combat this issue and provide a cure for AIDS. Gnidimacrin activates latent HIV-1 replication and inhibits HIV-1 infection at picomolar concentrations. This natural diterpene was able to markedly reduce the latent HIV-1 DNA level and the frequency of latently infected cells. Therefore, gnidimacrin is an excellent lead compound, and its anti-HIV potential merits further investigation. Twenty-nine modified gnidimacrin derivatives were synthesized and evaluated in assays for HIV replication and latency activation to establish which molecular structures must be maintained and which can tolerate changes that may be needed for better pharmacological properties. The results indicated that hydroxyl substituents at C-5 and C-20 are essential, while derivatives modified at 3-OH with aromatic esters retain anti-HIV replication and latent activation activities. The half-lives of the potent GM derivatives are over 20 h, which implies that they are stable in the plasm even though they contain ester linkages. The established structure activity relationship should be useful in the development of gnidimacrin or structurally related compounds as clinical trial candidates.

A series of novel alpha-aminophosphonate derivatives were synthesized via simple and an efficient method from the three-component condensation reaction of 5-aminoindan or 3,4-(methylenedioxy)aniline, aromatic aldehydes and diethyl phosphite by employing graphene nanosheets-silver nanoparticles (GNS-AgNPs) as catalyst under ultrasonication and solvent-free condition. GNS-AgNPs was prepared in situ by simultaneous reduction of graphene oxide (GO) and silver nitrate (AgNO3) using sodium borohydride (NaBH4) as a reducing agent. The surface characterization of GNS-AgNPs was done using X-ray diffraction (XRD), Fourier transform infrared (FTIR), UV-Vis spectroscopy (UV-Vis), Thermogravimetric analysis (TGA), Raman spectroscopy and Field emission scanning electron microscopy (FE-SEM). The GNS-AgNPs are recyclable up to fifth run with minimal loss of its activity. Convenient operational simplicity, mild conditions, excellent yields of products, consistent performance and the reusability of catalyst makes this protocol feasible and attractive.

Chalcones are interesting candidates for anti-cancer drugs due to the ease of their synthesis and their extensive biological activity. The study presents antitumor activity of newly synthesized chalcone analogues with a methoxy group on a panel of canine lymphoma and leukemia cell lines. The antiproliferative effect of the 2 ‘-hydroxychalcone and its methoxylated derivatives was evaluated in MTT assay after 48 h of treatment in different concentrations. The proapoptotic activity was studied by cytometric analysis of cells stained with Annexin V/FITC and propidium iodide and by measure caspases 3/7 and 8 activation. The DNA damage was evaluated by Western blot analysis of phosphorylated histone H2AX. The new compounds had selective antiproliferative activity against the studied cell lines, the most effective were the 2 ‘-hydroxy-2 ”,5 ”-dimethoxychalcone and 2 ‘-hydroxy-4 ‘,6 ‘-dimethoxychalcone. 2 ‘-Hydroxychalcone and the two most active derivatives induced apoptosis and caspases participation, but some percentage of necrotic cells was also observed. Comparing phosphatidylserine externalization after treatment with the different compounds it was noted that the addition of two methoxy groups increased the proapoptotic potential. The most active compounds triggered DNA damage even in the cell lines resistant to chalcone-induced apoptosis. The results confirmed that the analogues could have anticancer potential in the treatment of canine lymphoma or leukemia.

A detailed structural analysis has been carried out on four chalcone (E)-1-(2-hydroxyphenyl)-3-phenylprop-2-en-1-one derivatives, having a varying number of methoxy substituents, namely (E)-3-(3,4-dimethoxyphenyl)-1-(2-hydroxyphenyl)prop-2-en-1-one, (1), (E)-3-(4-methoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one, 2, (E)-3-(2,5-dimethoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one, 3, and (E)-3-(2,5-dimethoxyphenyl)-1-(2-hydroxy-3,4-dimethoxyphenyl)prop-2-en-1-one, 4. Crystal structures were determined at 100 K by single crystal X-ray diffraction. Compound 2 displayed an unexpectedly large interplanar angle of 25 and 28(,o) between the phenyl groups in the two independent molecules, due to the formation of a dimeric substructure requiring a pronounced phenyl group rotation to minimise steric hindrance. Such a substructure was absent in 1, 3 and 4. In all cases the 2-hydroxyl substituent forms intramolecular hydrogen bonds with its neighbouring carbonyl group. Different combinations of C-H center dot center dot center dot O, C-H center dot center dot center dot pi and/or pi center dot center dot center dot pi interactions are displayed by 1, 3 and 4, with also C=O center dot center dot center dot pi intermolecular interactions present in 2. The relative contributions of various intermolecular contacts in these structures were investigated using Hirshfeld surfave analysis and the associated two dimensional fringerprint plots. Important molecule pairs were identified in the crystal structures using the PIXEL method. The PIXEL lattice energy calculations revealed that in all cases the dispersion contribution was the major contributor to the packing stabilization, followed by the Coulombic contribution. A search of structures of alkoxy derivatives of (E)-1-(2-hydroxyphenyl)-3-phenylprop-2-en-1-one derivatives in the CCDC data base has also been carried out. (C) 2020 Published by Elsevier B.V.

Solar-driven water vaporization is considered one of the most sustainable technologies to solve water scarcity. However, the advanced design solar absorber system is still required for highly efficient steam generation. Here we develop a novel system for water evaporation through assembly of carbon dots within microchannels of processed wood. Not only is a dual-layer structure including of heat barrier and water transport channel formed, but also the modulation of carbon dot energy structures in favor of photothermal conversion is realized synchronously. This system exhibits higher water evaporation rate and energy efficiency for solar to steam generation than other black photothermal sheets (e.g. carbon nanotube, graphene, graphene oxide). On the one hand, the constructed size-dependent vaporization enthalpy theory shows that the micropores are beneficial to reduce vaporization enthalpy of water. On the other hand, the presented direct evidences for the roles of oxidation functional groups in solar thermal evaporation demonstrate that hydroxyl groups can improve solar-to-heat efficiency. Therefore, tailoring pore sizes and surface functional groups could be an efficient method for solar-to-vapor systems. (C) 2019 Elsevier Ltd. All rights reserved.
