The hydrazide obtained from furan-2(3H)-one integrated with a quinolin-2(1H)-one core reported previously by our research group was utilized as a building block synthon to obtain some pyrrolone, pyridazinone, oxadiazole, and triazole derivatives through treating with some carbon electrophilic reagents, for example, chloroacetyl chloride, benzoyl chloride, acetic anhydride, carbon disulfide, 3,4-dimethoxybenzaldehyde, and 2-oxoquinolin-3-carbaldehyde to achieve the target heterocycles. The newly synthesized compounds were evaluated as immunomodulator against highly pathogenic avian influenza virus (H5N8). The compounds 1, 11, and 17 displayed the highest potency (100% protection).

Computed Properties of C9H7NO2. I found the field of Pharmacology & Pharmacy; Virology very interesting. Saw the article Host RNA quality control as a hepatitis B antiviral target published in 2021, Reprint Addresses Block, TM (corresponding author), Baruch S Blumberg Inst, Doylestown, PA 18902 USA..

Inhibition of the host RNA polyadenylating polymerases, PAPD5 and PAPD7 (PAPD5/7), with dihydroquinolizinone, a small orally available, molecule, results in a rapid and selective degradation of hepatitis B virus (HBV) RNA, and hence reduction in the amounts of viral gene products. DHQ, is a first in class investigational agent and could represent an entirely new category of HBV antivirals. PAPD5 and PAPD7 are noncanonical, cell specified, polyadenylating polymerases, also called terminal nucleotidyl transferases 4B and 4A (TENT4B/A), respectively. They are involved in the degradation of poor-quality cell transcripts, mostly noncoding RNAs and in the maturation of a sub-set of transcripts. They also appear to play a role in shielding some mRNA from degradation. The results of studies with DHQ, along with other recent findings, provide evidence that repression of the PAPD5/7 arm of the cell RNA quality control pathway, causes a profound (multifold) reduction rather than increase, in the amount of HBV pre-genomic, pre-core and HBsAg mRNA levels in tissue culture and animal models, as well. In this review we will briefly discuss the need for new HBV therapeutics and provide background about HBV transcription. We also discuss cellular degradation of host transcripts, as it relates to a new family of anti-HBV drugs that interfere with these processes. Finally, since HBV mRNA maturation appears to be selectively sensitive to PAPD5/7 inhibition in hepatocytes, we discuss the possibility of targeting host RNA quality control as an antiviral strategy.

A series of thiosemicarbazone derivatives was prepared and their anti-tumor activity in vitro was tested. The X-ray investigation performed for compounds T2, T3 and T5 confirmed the synthesis pathway and assumed molecular structures of analyzed thiosemicarbazones. The conformational preferences of the thiosemicarbazone system were characterized using theoretical calculations by AM1 method. Selected compounds were converted into complexes of Cu (II) ions. The effect of complexing on anti-tumor activity has been investigated. The copper(II) complexes, with Schiff bases T1, T10, T12, T13, and T16 have been synthesized and characterized by chemical and elemental analysis, FTIR spectroscopy and TGA method. Thermal properties of coordination compounds were studied using TG-DTG techniques under dry air atmosphere. G361, A375, and SK-MEL-28 human melanoma cells and BJ human normal fibroblast cells were treated with tested compounds and their cytotoxicity was evaluated with MTT test. The compounds with the most promising anti-tumour activity were then selected and their cytotoxicity was verified with cell cycle analysis and apoptosis/necrosis detection. Additionally, DNA damages in the form of a basic sites presence and the expression of oxidative stress and DNA damage response genes were evaluated. The obtained results indicate that complexation of thiosemicarbazone derivatives with Cu (II) ions improves their antitumor activity against melanoma cells. The observed cytotoxic effect is associated with DNA damage and G2/M phase of cell cycle arrest as well as disorders of the antioxidant enzymes expression.

Accurate dietary assessment is a challenge in nutritional research, needing powerful and robust tools for reliable measurement of food intake biomarkers. In this work, we have developed a novel quantitative dietary fingerprinting (QDF) approach, which enables for the first time the simultaneous quantitation of about 350 urinary food-derived metabolites, including (poly)phenolic aglycones, phase II metabolites, and microbial-transformed compounds, as well as other compounds (e.g., glucosinolates, amino acid derivatives, methylxanthines, alkaloids, and markers of alcohol and tobacco consumption). This method was fully validated for 220 metabolites, yielding good linearity, high sensitivity and precision, accurate recovery rates, and negligible matrix effects. Furthermore, 127 additional phase II metabolites were also included in this method after identification in urines collected from acute dietary interventions with various foods. Thus, this metabolomic approach represents one-step further toward precision nutrition and the objective of improving the accurateness and comprehensiveness in the assessment of dietary patterns and lifestyles.

In this work, nanomesoporous silica has been prepared from horsetail (Equisetum arvense), which is a medicinal plant, with high surface area. This natural silica has been applied as a support to prepare H3PW12O40 immobilized on aminated epibromohydrin-functionalized Fe3O4@SiO2 nanoparticles (Fe3O4@SiO2-EP-NH-HPA) as a highly powerful magnetically solid acid catalyst. Characterization of this nanocatalyst has been investigated by a variety of techniques such as FTIR, XRD, N-2 adsorption-desorption, TEM, SEM-EDX, TGA, VSM, ICP-OES and elemental analysis. This magnetically solid acid nanocatalyst has been successfully used for the one-pot green synthesis of pyrano[2,3-c]pyrazole derivatives in an aqueous medium at room temperature. The procedure resulted in structurally different pyrano[2,3-c]pyrazoles in excellent yields in very low reaction times. Moreover, this magnetically solid acid nanocatalyst can be simply recovered by an external magnetic field and reused for seven consecutive reaction cycles without significant loss of activity. Graphic abstract In this work, Fe3O4@SiO2-EP-NH-HPA as a highly powerful magnetically solid acid nanocatalyst based on natural silica which was extracted from a medicinal plant was prepared and characterized using various techniques. The activity of the new catalyst was tested for the synthesis of pyrano[2,3-c]pyrazole derivatives.

Series of highly polar stilbene (1a-e), diphenylbutadiene (2a-c) and phenylethenyIthiophene (3a-c) derivatives were prepared via Horner-Wadsworth-Emmons method with a view to produce new and efficient materials for second harmonic generation (SHG) in the solid-state. The single-crystal X-ray structures of compounds 1-3 reveal extensive polymorphism and a peculiar photodimerization of the 2-chloro-3,4-dimethoxy-4′-nitrostilbene derivative 1a to afford two polymorphs of tetra-aryl cyclobutane 4. The stilbene congeners 2-chloro-3,4-dimethoxy-4′-nitrostilbene (1a. non-centro), 5-bromo-2-hydroxy-3-nitro-4′-nitrostilbene (1b) and 4-dimethylamino-4′-nitrostilbene (1e), as well as 4′-fIuoro-4 ”-nitro-1,4-diphenyl-1,3-butadiene (2a) present the ideal, non-centrosymmetric arrangement of the chromophores for nonlinear optical (NLO) activity. Compounds lb and 2a exhibit only relatively Low intensity for second harmonic generation (0.04 and 0.18 times that of urea reference, respectively), while the stilbene polymorph 1a.non-centro shows NLO activity of over 32 times that of urea. In addition, the conjugated diaromatic compounds 1-3 display fluorescence behaviour in CH2Cl2 solutions with the exception of stilbene derivative 1b.

Dopamine D1/D2 receptors are important targets for drug discovery in the treatment of central nervous system diseases. To discover new and potential D1/D2 ligands, 17 derivatives of tetrahydroprotoberberine (THPB) with various substituents were prepared by chemical synthesis or microbial transformation using Streptomyces griseus ATCC 13273. Their functional activities on D1 and D2 receptors were determined by cAMP assay and calcium flux assay. Seven compounds showed high activity on D1/D2 receptor with low IC50 values less than 1 mu M. Especially, top compound 5 showed strong antagonistic activity on both D1 and D2 receptor with an IC50 of 0.391 and 0.0757 mu M, respectively. Five compounds displayed selective antagonistic activity on D1 and D2 receptor. The SAR studies revealed that (1) the hydroxyl group at C-9 position plays an important role in keeping a good activity and small or fewer substituents on ring D of THPBs may also stimulate their effects, (2) the absence of substituents at C-9 position tends to be more selective for D2 receptor, and (3) hydroxyl substitution at C-2 position and the substitution at C-9 position may facilitate the conversion of D1 receptor from antagonist to agonist. Molecular docking simulations found that Asp 103/Asp 114, Ser 107/Cys 118, and Trp 285/Trp 386 of D1/D2 receptors are the key residues, which have strong interactions with the active D1/D2 compounds and may influence their functional profiles.

Efficiently and selectively detecting definite organic compound is attractive but challenging. In this study, we report two novel cucurbit[6]uril (Q[6]) – based supramolecular assemblies {(NH4)(2)[Zn(H2O)(6)][Mg(TPTCA) (H2O)(2)](4)(Q[6])(6)}center dot 66H(2)O (1) and { [Zn(PBPCA)(H2O)(2)]Q[6]center dot 21H(2)O (2) [H(3)TPTCA = [1,1′: 3′,1 ”-terphenyl]-4, 4 ”,5′-tricarboxylic acid and H(2)PBPCA = pyridine-3,5-bis(phenyl-4-carboxylic acid)] by using metal complexes with multiaromatic carboxylate ligands as structure-directing agent. The formation of these assemblies is ascribed to the non-covalent pi-pi, C-H-pi, hydrogen bonding interactions between the outer-surface of Q[6] and coordination complexes. More impressively, 1 and 2 exhibit enhanced fluorescence compared with the ligands and can serve as chemical sensors for aromatic amines and nitroaromatic compounds, particularly for 2,4,6-trinitrophenol (TNP), via fluorescence quenching effect with high selectivity and sensitivity.

This work aims to unravel the impact of disubstitution patterns on the physical properties and processing characteristics of indole-based aromatic polyesters. A series of hydroxyl-carboxylate (AB-type) monomers with 1,5-disubstituted indole and 3-6 methylene units was conveniently synthesized and used in bulk polycondensation to yield the corresponding polyesters with decent molecular weight. These new monomers and polyesters showed enhanced thermal stability compared to the previously reported monomers and polyesters with a 1,3-disubstituted indole structure. According to DSC results, these polyesters showed tunable glass transition temperatures (T-g similar to 57-80 degrees C), depending on the length of the aliphatic methylene units. DSC and WAXD measurements revealed that these polymers did not crystalize from melt, but the ones with 3 or 5 methylene units per repeating unit crystalized from solution. Finally, we demonstrated that the new polyesters with 1,5-disubstituted indole units could be crosslinked using sustainable aromatic aldehyde, which could further enhance their thermal properties.
