The Synthesis of Adamantane Ring Containing Benzimidazole, Benzoxazole, and Imidazo[4,5-e]benzoxazole Derivatives from 3-Aminophenol

Adamantane derivatives containing heterocycles such as benzimidazoles, benzoxazoles, and fused imidazo[4,5-e]benzoxazoles were synthesized from 3-aminophenol. The route started with amidation of adamantane-1-carboxylic acid chloride with 3-aminophenol furnishing N-(3-hydroxyphenyl)adamantane-1-carboxamide. Subsequent nitration gave three regioisomers. After reduction of the nitro groups, the respective aniline derivatives were used in the formation of benzimidazole and benzoxazole rings. The cyclization of the 2-substituted benzoxazole ring was performed using two methods: via condensation of N-(2-amino-3-hydroxyphenyl)adamantane-1-carboxamide with carbonitriles in the presence of a Lewis acid or via Cu(II)-catalyzed oxidative coupling of aminophenol with aromatic aldehydes. The benzimidazole ring formed by acid-catalyzed cyclization of N-(2-amino-5-hydroxyphenyl)adamantane-1-carboxamide was then converted to a tricyclic system after three synthetic steps.

Benzoxazole-based nematic liquid crystals containing ethynyl and two lateral fluorine atoms with large birefringence

New kinds of heterocyclic mesogenic compounds containing benzoxazole, ethynyl, and laterally fluorinated phenyl groups, namely 2-[4-[2-[4-alkoxyphenyl]ethynyl]-2,3-difluorophenyl]benzoxazole derivatives (nPEDFPBx), are synthesized and evaluated. The compounds nPEDFPBx except nitro-substituted ones have enantiotropic nematic mesophases with mesophase ranges of 16-86 degrees C and 29-108 degrees C on heating and cooling, respectively. The results show that introduction of two lateral fluorine atoms into molecule results in enhanced nematic mesophase stability. Meanwhile, nPEDFPBx displays much higher birefringence (0.507-0.624) than common tolanebased liquid crystals, which is ascribed to its large pi-conjugated molecule composed of benzene, ethynyl, and benzoxazole mesogenic unit. The nPEDFPBx has a high potential to serve as a dopant for liquid crystal mixture. [GRAPHICS] .

A benzoxazole derivative as an inhibitor of anaerobic choline metabolism by human gut microbiota

Metabolic pathways mediated by human gut bacteria have emerged as potential therapeutic targets because of their association with the pathophysiology of various human diseases. The anaerobic transformation of choline into trimethylamine (TMA) by gut microbiota is directly linked to type 2 diabetes, fatty liver disease, and cardiovascular diseases. Structural analogs of choline have been developed as competitive inhibitors of choline TMA-lyase (CutC), a key enzyme for the conversion of choline to TMA. However, weak to moderate CutC inhibitory profiles of the choline analogs limit their further advancement into clinical translation. In this study, we introduce a glycomimetic-based approach for the identification of CutC inhibitors with intestinal metabolic stability. Our workflow started with screening of a small library of glycomimetics for metabolic stability in the presence of human intestinal S9 fraction. Further screening using an in vitro CutC inhibitory assay identified a benzoxazole ligand (BO-I) as a CutC inhibitor with an IC50 value of 2.4 +/- 0.3 mu M. Kinetic analysis revealed that BO-I functions as a non-competitive inhibitor of CutC. Interestingly, BO-I reduced the production of TMA in whole cell assays of multiple bacterial strains as well as in complex biological environments. Therefore, structural optimization of BO-I holds promise for the development of efficient gut microbiota-targeted small molecules.

Metal-free selective synthesis of 2-substituted benzimidazoles catalyzed by Bronsted acidic ionic liquid: Convenient access to one-pot synthesis of N-alkylated 1,2-disubstituted benzimidazoles

A novel efficient method for the selective synthesis of 2-substituted benzimidazoles is described through condensation reaction of o-phenylenediamines with a wide rang of aliphatic, aromatic and heteroaromatic aldehyde substrates using Bronsted acidic ionic liquid as a reusable catalyst under metal-free conditions at ambient temperature. Notably, Dodecylimidazolium hydrogen sulfate ([Dodeclm][HSO4]) is the most efficient catalyst for good to excellent yields of the corresponding products (up to 98%). Subsequently, this protocol was successfully applied for the preparation of N-alkylated 1,2-disubstituted benzimidazoles in high to excellent yields via sequential one-pot reaction. In addition, catalysts are recycled at least four times without significant loss in activity. (C) 2019 Elsevier Ltd. All rights reserved.

Encapsulation of Risperidone by Methylated beta-Cyclodextrins: Physicochemical and Molecular Modeling Studies

Risperidone (RSP) is an atypical antipsychotic drug which acts as a potent antagonist of serotonin-2 (5TH2) and dopamine-2 (D2) receptors in the brain; it is used to treat schizophrenia, behavioral and psychological symptoms of dementia and irritability associated with autism. It is a poorly water soluble benzoxazole derivative with high lipophilicity. Supramolecular adducts between drug substance and two methylated beta-cyclodextrins, namely heptakis(2,6-di-O-methyl)-beta-cyclodextrin (DM-beta-CD) and heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TM-beta-CD) were obtained in order to enhance RSP solubility and improve its biopharmaceutical profile. The inclusion complexes were evaluated by means of thermoanalytical methods (TG-thermogravimetry/DTG-derivative thermogravimetry/HF-heat flow), powder X-ray diffractometry (PXRD), universal-attenuated total reflectance Fourier transform infrared (UATR-FTIR), UV spectroscopy and saturation solubility studies. Job’s method was employed for the determination of the stoichiometry of the inclusion complexes, which was found to be 2:1 for both guest-host systems. Molecular modeling studies were carried out for an in-depth characterization of the interaction between drug substance and cyclodextrins (CDs). The physicochemical properties of the supramolecular systems differ from those of RSP, demonstrating the inclusion complex formation between drug and CDs. The RSP solubility was enhanced as a result of drug encapsulation in the CDs cavity, the higher increase being obtained with DM-beta-CD as host; the guest-host system RSP/DM-beta-CD can thus be a starting point for further research in developing new formulations containing RSP, with enhanced bioavailability.
