CC chemokine receptors 2 (CCR2) and 5 (CCR5) are involved in many inflammatory diseases; however, most CCR2 and CCR5 clinical candidates have been unsuccessful. (Pre)clinical evidence suggests that dual CCR2/CCR5 inhibition might be more effective in the treatment of such multifactorial diseases. In this regard, the highly conserved intracellular binding site in chemokine receptors provides a new avenue for the design of multitarget ligands. In this study, we synthesized and evaluated the biological activity of a series of triazolopyrimidinone derivatives in CCR2 and CCR5. Radioligand binding assays first showed that they bind to the intracellular site of CCR2, and in combination with functional assays on CCR5, we explored structure-affinity/activity relationships in both receptors. Although most compounds were CCR2-selective, 39 and 43 inhibited beta-arrestin recruitment in CCR5 with high potency. Moreover, these compounds displayed an insurmountable mechanism of inhibition in both receptors, which holds promise for improved efficacy in inflammatory diseases.

In the title molecule, C13H16N4O3, the mean planes of the phenyl and triazole rings are nearly perpendicular to one another as a result of the intramolecular C-H center dot center dot center dot O and C-H center dot center dot center dot pi(ring) interactions. In the crystal, layers parallel to (101) are generated by O-H center dot center dot center dot N, N-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonds. The layers are connected by inversion-related pairs of C-H center dot center dot center dot O hydrogen bonds. The experimental molecular structure is close to the gas-phase geometryoptimized structure calculated by DFT methods. Hirshfeld surface analysis indicates that the most important interaction involving hydrogen in the title compound is the H center dot center dot center dot H contact. The contribution of the H center dot center dot center dot O, H center dot center dot center dot N, and H center dot center dot center dot H contacts are 13.6, 16.1, and 54.6%, respectively.

It is still a great challenge to prepare lignin/polyolefin composites with good strength and toughness. Inspired by the energy sacrificial mechanism from biomaterials, dynamic hydrogen bonds (H-bonds) are incorporated into the lignin/ethylene-propylene-diene monomer (EPDM) composite system to improve the interfacial interactions between lignin and EPDM. Such H-bonding interactions are demonstrated to be able to simultaneously improve the modulus, strength, and toughness of lignin/EPDM composites without sacrificing the extensibility. This work provides a facile method for the high-valued utilization of lignin in the preparation of high-performance elastomer composites using bio-renewable resources as reinforcing agent.

Despite the increasing detection of emerging substances in the environment, the identity of most are left unknown due to the lack of efficient identification methods. We developed a non-target analysis method for identifying unknown substances in the environment by liquid chromatography/high-resolution mass spectrometry (LC/HRMS) with a product ion and neutral loss database (PNDB). The present analysis describes an elucidation method with elemental compositions of the molecules, product ions, and corresponding neutral losses of the unknown substance: (1) with the molecular formula, possible molecular structures are retrieved from two chemical structure databases (PubChem and ChemSpider); then (2) with the elemental compositions of product ions and neutral losses, possible partial structures are retrieved from the PNDB; and finally, (3) molecular structures that match the possible partial structures are listed in order of number of hits. A molecular structure with a higher number of hits is more similar to the structure of the analyzed substance. The performance of the non-target method was evaluated by simulated analysis of 150 LC/HRMS spectra registered in MassBank. First, all substances of the same mass data (41/41) and 68% (39/57) of the mass data of the same substances not registered in the PNDB were elucidated. It was demonstrated that 14% (7/52) and 31% (16/52) of the substances with no mass spectral data registered in the PNDB were obtained at the first and within the fifth place, respectively. Owing to the fact that 10 of the total hits occurred in product ions and neutral losses, almost 50% of the substances evaluated with this method were placed at the top 4 positions in the similarity ranking. Importantly, the proposed method is effective for analyzing mass spectral data that has not been registered in the PNDB and thus is expected to be used for a variety of non-target analyses.

A series of new thiazoline derivatives were synthesized. Structure analyses were accomplished employing H-1-NMR, C-13-NMR, X-ray and MS techniques. The in vitro antitumor activities were assessed against human hepatocellular carcinoma (HepG-2) and colorectal carcinoma (HCT-116) cell lines. The results revealed that the thiazolines 5b and 2c exhibited significant activity against the two cell lines. The in vitro antimicrobial screening showed that the thiazolines 2c, 5b and 5d showed promising inhibition activity against Salmonella sp. Additionally, the inhibition activity of thiazolines 2e and 5b against Escherichia coli was comparable to that of the reference compound gentamycin.

Ten 5-functionalized derivatives of 1,3-oxazole-4-carboxylate and 1,3-oxazole-4-carbonitrile were synthesized and their antiviral activities against the human cytomegalovirus (HCMV) were evaluated in vitro. Bioassays showed that seven compounds exhibited considerably higher antiviral activity (EC50:<0.05M) against a normal laboratory HCMV strain (AD-169) in human foreskin fibroblast cells than Ganciclovir (EC50=0.32M), an anti-HCMV agent in clinical use. Additionally, the HCMV-resistant isolate (GDGr K-17) was tested for sensitivity to 1,3-oxazole derivatives with most antiviral potency against the strain AD169. A one of them (5-((2-hydroxyethyl)(methyl)amino)-2-(4-methylphenyl)-1,3-oxazole-4-carbonitrile) showed very high potency (EC50:<0.05; CC50: >150 mu M, and SI50=3125) towards the resistant isolate compared to standard drugs Cidofovir (EC50=0.10 mu M, CC50: >30 mu M and SI50: <4). But, in contrast to the primary assays, the antiviral activity of these compounds against both the normal strain and the resistant isolate of HCMV were considerably less than one of Cidofovir in secondary assay. These results provided evidence that derivatives of 1,3-oxazole could be useful for developing new anti-HCMV drugs. Recommanded Product: 61-82-5.

A novel pyridinium salt derivative, 2,3,4,5,6-pentaphenyl-1-(1H-1,2,4-triazol-3-yl)pyridinium perchlorate (1) has been designed and synthesized by using pyrylium perchlorate and 3-amino-1H-1,2,4-triazole as ingredients, which can be exploited for the binding and specific sensing of anion via hydrogen bonds. Compound 1 exhibits intense blue emission in solution with maximum emission at 469 nm with a red shift relative to that (426 nm) of solid state. The luminescence intensity of 1 could be selectively and sensitivity quenched with acetate ion and fluorine ion among various anions including F-, Cl-, Br-, I-, AcO- and NO3-. Furthermore, the possible detection mechanism was investigated. This work could contribute a credible potential sensing application of 1,2,4-triazolyl substituted pentaphenylpyridinium salts towards the specific anions in biological and environmental concerns.

Recently, activated carbon adsorption for water treatment regained substantial attention due to the emerging task to remove trace organic compounds such as pesticides. In many applications, especially in decentralized water treatment, one major drawback of adsorbents is their limited recyclability due to inadequate logistics or uneconomical reactivation. In this lab-scale study, we present the temperature swing adsorption in the aqueous phase that allows the in situ regeneration of fixed-bed adsorbers, and prove its technical feasibility. Complying with circular water economy principles, we eliminated the pivotal need for regular replacement and consumables by employing only clean water instead of dedicated regeneration solutions. Adsorption of the herbicide amitrole in aqueous solution on granular activated carbon was exothermic (Delta H = -14.4 +/- 3.2 kJ mol(-1) for T = 20-94 degrees C) and followed the Freundlich model. The proposed method consisting of a short counterflow flush with liquid water at 125 degrees C effectively regenerated the adsorbent. Hence, we obtained a cyclic steady state operation with breakthrough after 122 +/- 14 bed volumes (at c(out)/c(in) = 0.2), cycle-average rejection of 90 +/- 1%, and water recovery of up to 78 +/- 4%. No thermal aging of adsorbent was observed over the investigated 17 cycles.

Solvothermal reactions of Zn(NO3)(2)center dot 6H(2)O, 3-amino-1,2,4-triazole as well as three different carboxylate ligands afforded three novel coordination polymers: [Zn-2 (azdc) (atz) (OH) (H2O)](n) (1), {[Zn-1.5 (btc)(0.5) (atz)]center dot 1.5H(2)O}(n) (2), and {[Zn-4 (nipa)(2) (atz)(3)(OH) (H2O)]center dot 2H(2)O}(n) (3) (H(2)azdc = 4,4′-azobenzoic acid, H(4)btc = 1,2,4,5-benzenetetracarboxylic acid, 5-H(2)nipa = 5-nitroisophthalic acid, Hatz = 3-amino-1,2,4-triazole). Moreover, the three coordination polymers have been characterized by IR spectroscopy, elemental analysis, single-crystal X-ray diffraction, and powder X-ray diffraction techniques. Complex 1 reveals a 2D layer structure, which is further connected through pi-pi stacking interactions forming a 3D supramolecular network. Complex 2 exhibits a 3D porous framework with 1D open channels. Complex 3 shows a 3D pillared-layer framework. Notably, the thermal decomposition processes of 1-3 were investigated by simultaneous TG-DSC techniques. The TG curves reveal that complexes 1-3 possess pretty good thermostability up to 321 degrees C, 416 degrees C and 418 degrees C, respectively. The apparent activation energy E (E-1 = 194.975 kJ mol(-1), E-2 = 220.360 kJ mol(-1), E-3 = 223.600 kJ mol(-1)) and the pre exponential factor A of skeleton collapse for the complexes 1-3 were calculated by the integral Kissinger’s method and Ozawa-Doyle’s method. The structural stability could be illustrated from the point of thermal decomposition kinetics.
