The reactivity of 3-substituted-6,8-dimethylchromone derivatives 1-5 was investigated toward selected nucleophilic reagents namely; 3-amino-1,2,4-triazole, 2-aminobenzimidazole, 7-chloro-4-hydrazinoquinoline, and 5,6-diphenyl-3-hydrazino-1,2,4-triazine. These nucleophiles were allowed to react with 6,8-dimethylchromone-3-carboxaldehyde (1) through condensation with the aldehyde group with opening of gamma-pyrone ring giving compounds 6, 7, 10, and 11. Reactions with 6,8-dimethylchromone-3-carbonitrile (2), and 6,8-dimethylchromone-3-carboxylic acid (3) occur via attack at position 2 in both compounds followed by cycloaddition onto the nitrile function (in case of carbonitrile 2) or decarboxylation and cyclocondensation with the carbonyl group (in case of carboxylic acid 3). The current nucleophilic reagents reacted with simple condensation products 4 and 5, in boiling dioxane, through nucleophilic addition at the exocyclic vinyl bond followed by addition at the C(sic)N group giving 6,8-dimethylchromone linked various heterocyclic systems 20-27.

Utilization of lignocellulosic biomass is increasingly important. Jasminum nudiflorum Lindl. (JNL) is a widely cultivated landscape plant in China. To evaluate the chemical components, pyrolysis characteristics as well as the potential values of JNL bark for utilization, the components were extracted using methanol, ethanol, and benzene/ethanol (2:1, v/v) and pyrolyzed from room temperature to 300 ?C, respectively. Many components were detected in the extracts and the pyrolyzates of JNL bark and their chemical properties were analyzed. The compounds identified in the extracts and the pyrolyzates of JNL bark included acids, aldehydes, alcohols, esters, ketones, aromatics, saccharides, olefins, and nitrogen-containing compounds. Some of the identified compounds, such as urs-12-en-28-al, 3-(acetyloxy)-, (3.beta.)-, 5-hydroxymethylfurfural, and vanillin, are widely used in the medical, energy, and food industries. The pyrolysis of JNL bark using thermogravimetric (TG) analyzer showed the highest reaction rate occurred at between 200 and 300 ?C where the maximum mass loss was observed. According to the Coats-Redfern method, the calculated apparent activation energy (E) and pre-exponential factor (A) of the pyrolysis process of JNL bark were 52.04 kJ mol- 1 and 3.14 ? 105 min-1, respectively. This research provides information on the components and pyrolysis characteristics of JNL bark, which shows great potential for application in medical, food, and chemical industries.

A new naphthalenediimide derivative, 2, 7-di (1, 2, 4-triazolyl) benzophenanthroline-tetraone (3-DTBPT) is synthesized by the condensation reaction of 1, 4, 5, 8-naphthalenetetracarboxylic anhydride (NTCDA) and 3-amino-1, 2, 4-triazole (3-AT). The 3-DTBPT material is characterized by Fourier transform infrared spectrum, X-ray diffraction, thermogravimetric analysis, solid state NMR spectra, field emission scanning electron microscopy, elemental analysis and Brunauer-Emmett-Teller surface. 3-DTBPT is insoluble in organic electrolyte. When used as a cathode material of lithium-ion batteries, 3-DTBPT exhibits an excellent cyclic stability, keeping a specific capacity of 110 mA h g(-1) and a nearly 94.8% capacity retention after 50 cycles at 50 mA g(-1).

Cancer is a leading cause of human death worldwide. One of the greatest challenges in cancer therapy is the discovery and design of novel products with potential anti-tumor activities. In this study, a new protocol involves three-component condensation of the 3-amino-1,2,4-triazole as a 1,3-binucleophile, versatile aldehydes and Nmethyl-1-(methylthio)-2-nitroethenamine as an enamine analogous in the presence of trichloroacetic acid as a Bronsted-Lowry acidic promoter leads to new functionalized N-alkyl-6-nitro-3,5-dihydro-[1,2,4]triazolo [1,5-a] pyrimidin-7-amine in moderate to good yields. The presence of five nitrogen heteroatoms in the product structure has gathered immense attention among chemists and biologists due to their biological values. Therefore, we evaluated the anti-tumor activity of our synthetic compounds on different cancer cells including human malignant melanoma cells (A375), prostate cancer cells (PC3 cells, LNCaP cells) and normal cells HDF (human dermal fibroblast). Notably, we found that compound 4b that contains a nitro group has the best antitumor activity on three different cancer cells. By using DAPI staining, we showed cancer cells death. Apoptosis induction was shown using quantitative real time PCR (qRT-PCR) by evaluating of Bax and Bcl2 mRNA levels. Finally, we demonstrated that 4b has epithelial-to-mesenchymal transition (EMT) inhibition effect on cancer cells (by induction of E-cadherin and reduction of vimentin mRNA expression levels as two potential EMT markers). So, 4b could be an anti-cancer promising drug. Although, in vivo experiments will be required to evaluate possible side effects.

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.

Chemical transformations of chromone-3-carbonitrile (1) with some substituted hydrazines, namely, thiosemicarbazide, S-methyl/benzyldithiocarbazate, 7-chloro-4-hydrazinoquinoline, and 3-hydrazino-5,6-diphenyl-1,2,4-triazine, led to substituted pyrazoles 2, 5-8. Ring opening of carbonitrile 1 followed by recyclization with 3-amino-1,2,4-triazole and 2-aminobenzimidazole gave triazolo[1,5-a]pyrimidine 9 and pyrimido[1,2-a]benzimidazole 10, respectively. Treatment of carbonitrile 1 with some heterocyclic amines produced 2-amino-3-substituted-chromones 11 and 12. The novel 3-hydroxychromeno[4,3-b]pyrazolo[4,3-e]pyridin-5(1H)-one (13) was efficiently synthesized from the ring conversion of carbonitrile 1 with cyanoacetohydrazide. A mixture of chromeno[2,3-b]naphthyridine 14 and chromeno[4,3-b]pyridine 15 was obtained from base catalyzed transformation of carbonitrile 1 with malononitrile dimer. A diversity of novel annulated chromeno[2,3-b]pyridines 16-22 was also synthesized. Chromeno[2,3-b]pyrrole-2-carboxylate 23 was obtained from the reaction of carbonitrile 1 with ethyl chloroacetate. Structures of the new synthesized products were deduced on the basis of their analytical and spectral data.

Computed Properties of C2H4N4

Odors carrying intrinsic values often trigger instinctive aversive or attractive responses. It is not known how innate valence is encoded. An intuitive model suggests that the information is conveyed through specific channels in hardwired circuits along the olfactory pathway, insulated from influences of other odors, to trigger innate responses. Here, we show that in mice, mixing innately aversive or attractive odors with a neutral odor and, surprisingly, mixing two odors with the same valence, abolish the innate behavioral responses. Recordings from the olfactory bulb indicate that odors are not masked at the level of peripheral activation and glomeruli independently encode components in the mixture. In contrast, crosstalk among the mitral and tufted (M/T) cells changes their patterns of activity such that those elicited by the mixtures can no longer be linearly decoded as separate components. The changes in behavioral and M/T cell responses are associated with reduced activation of brain areas linked to odor preferences. Thus, crosstalk among odor channels at the earliest processing stage in the olfactory pathway leads to re-coding of odor identity to abolish valence associated with the odors. These results are inconsistent with insulated labeled lines and support a model of a common mechanism of odor recognition for both innate and learned valence associations.
