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.

Copper (II) immobilized on L-arginine-beta-cyclodextrin-functionalized magnetite nanoparticles (nano-Fe3O4@L-arginine-CD-Cu(II)) were successfully synthesized and fully characterized using FT-IR, XRD, SEM, EDX, ICP, TGA and VSM techniques. The catalytic activity of these magnetically retrievable nanoparticles was evaluated in the direct oxidation of primary alcohols and benzyl halides to acids in neat conditions that was observed to proceed well and products were obtained in good yields. In addition to showing good catalytic activity, the magnetic catalyst is easy to synthesize and can be recycled at least five times with little loss in activity. (C) 2020 Elsevier B.V.

Chalcone based structures have many interesting biological properties like anti-malarial, anticancer, antiviral, antibacterial, antifungal, anti-hyperglycaemic and photo-cytotoxicity activities. In this study, the novel chalcone derivatives (1a-11) have been synthesized and investigated for antimicrobial activities. The MIC results of antimicrobial activities reveal that one of the chalcone derivative (2-Br- and 4OCH(3)- group) against specific bacteria are quite significant. 3D QSAR, three dimensional quantitative structure activity is one of the most powerful technique which involves the quantitative relationship between the biological activity of a set of compounds and their three dimensional structural properties, using statistical correlation methods. Pharmacophore modelling and molecular docking play an important role in drug design. To elucidate the relationship between structures and its activity, field-based 3D QSAR analysis has been carried out of novel chalcone derivatives. Structural properties such as electrostatic, hydrophobic, aromatic, and hydrogen-bond donor and acceptor have been worked out for novel chalcone derivatives. To investigate the influence of drugstore, chalcone derivatives (1a-11) have docked with receptor 210K and results displayed the highest Gscore of ligand If (3-OCH2C6H5-4-OCH3- group).
