Abstract: A series of novel 1-[5-[6-[(2-benzoylbenzofuran-5-yl)methyl]-2-oxo-2H-chromen-3-yl]thiazol-2-yl]urea derivatives were synthesized by the reaction of 3-(2-aminothiazol-5-yl)-6-[(2-benzoylbenzofuran-5-yl)methyl]-2H-chromen-2-one with various substituted amines and triphosgene, in the presence of a base. The chemical structures of newly synthesized compounds were elucidated by 1H NMR, 13C NMR, IR, MS, and HRMS spectral data. The synthesized compounds evaluated for their inhibitory effects as anti-microbial activity and cytotoxicity. Most of the compounds exhibited a promising anti-microbial activity against the selected Gram-positive and Gram-negative bacterial strains at MIC values ranging from 0.071 to 0.199?muM and fungal pathogen was moderate to be good. The in vitro cytotoxicity testing of the title compounds was performed against cervical cancer (HeLa) cell lines. In the preliminary MTT cytotoxicity studies, the results have shown that there are a few of the synthesized compounds which exhibit a significant cytotoxicity at microliter concentration were found to non-toxic, their IC50 values ranging from 49.322/15 to 52.715/15?mm3.

The SELective INverse detection of carbon-proton CORrelation pulse sequence that yields a 1D spectrum of a proton directly bonded to a selected carbon resonance has been converted into a proton and carbon double-selective variant that provides a 1H spectrum of a selected proton that is long-range coupled to a specific carbon resonance. The resulting 1D proton multiplet exhibits a pure absorptive in-phase lineshape for precise measurement of specific long-range proton-carbon coupling constants in small organic molecules at natural abundance.

The volatile compounds of peaches (Prunus persica L.) obtained from five cultivars (Chongyanghong, Y1; Ruiguang 19, Y2; Zaohongxia, Y3; Zaohong 2, Y4; and Wuyuehuo, Y5) were analyzed by gas chromatography?olfactometry (GC?O), gas chromatography?mass spectrometry (GC?MS) and GC?flame photometric detection (FPD). A total of 40 odor-active volatile compounds were observed in the GC?O experiments. Amongst those compounds, hexanal, (Z)-3-hexen-1-ol, (E)-2-hexenal, 3-mercaptohexanol, nonanal, gamma-nonalactone, and gamma-decalactone contributed greatly to aroma of peach. In addition, thirty-four quantified compounds were demonstrated as important odorants according to odor activity values (OAVs > 1). Amongst these compounds, hexanal (OAV: 28?89), pentanal (OAV: 9?16), (E)-2-heptenal (OAV: 19?60), (E)-2-hexenal (OAV: 26?86), (E)-2-octenal (OAV: 10?42), (E)-2-nonenal (OAV: 8?94), gamma-decalactone (OAV: 13?34), delta-decalactone (OAV: 2?19), (R)-(?)-linalool (OAV: 29?76) and phenyl acetaldehyde (OAV: 4?59) were the most powerful compounds in five varieties of peach.

Amixicile is a promising derivative of nitazoxanide (an antiparasitic therapeutic) developed to treat systemic infections caused by anaerobic bacteria, anaerobic parasites, and members of the Epsilonproteobacteria (Campylobacter and Helicobacter). Amixicile selectively inhibits pyruvate-ferredoxin oxidoreductase (PFOR) and related enzymes by inhibiting the function of the vitamin B1 cofactor (thiamine pyrophosphate) by a novel mechanism. Here, we interrogate the amixicile scaffold, guided by docking simulations, direct PFOR inhibition assays, and MIC tests against Clostridium difficile, Campylobacter jejuni, and Helicobacter pylori. Docking simulations revealed that the nitro group present in nitazoxanide interacts with the protonated N4?-aminopyrimidine of thiamine pyrophosphate (TPP). The ortho-propylamine on the benzene ring formed an electrostatic interaction with an aspartic acid moiety (B456) of PFOR that correlated with improved PFOR-inhibitory activity and potency by MIC tests. Aryl substitution with electron-withdrawing groups and substitutions of the propylamine with other alkyl amines or nitrogen-containing heterocycles both improved PFOR inhibition and, in many cases, biological activity against C. difficile. Docking simulation results correlate well with mechanistic enzymology and nuclear magnetic resonance (NMR) studies that show members of this class of antimicrobials to be specific inhibitors of vitamin B1 function by proton abstraction, which is both novel and likely to limit mutation-based drug resistance.

Several imidazole-dioxolane compounds were synthesized and evaluated as novel inhibitors of heme oxygenase (HO). These compounds, which include a series of substituted thiophenol and substituted phenol derivatives of (2R,4S)-2-[2-(4-chlorophenyl)ethyl]-2-[(1H-imidazol-1-yl)methyl]-4-[(phenylsulfanyl)methyl]-1,3-dioxolane hydrochloride (3), in addition to smaller functionalized derivatives, continue our structure-activity studies by exploration of the aminothiophenol region (‘northeastern region’) in our original target structure azalanstat (1). In vitro, most of the compounds in this series were found to be highly potent inhibitors of the stress-induced isozyme HO-1 and the constitutive isozyme HO-2, showing only moderate selectivity for HO-1. Nevertheless, a few of the compounds displayed higher selectivity toward HO-1. None of the compounds having a larger appendage in the northeastern region were inhibitors of CYP2E1, whereas a compound having a relatively small fluorine substituent in this region did inhibit CYP2E1; all of the compounds tested exhibited high inhibitory potency against CYP3A1/3A2.
