The catalytic potential of pyridine-2-carboxlic acid has been evaluated for efficient, green and solvent free synthesis of 2,4,5-trisubstituted imidazole derivatives 3a-3m. The compounds 3a-3m were synthesized by one pot condensation reaction of substituted aromatic aldehydes, benzil, and ammonium acetate in good to excellent yields (74-96 %). To explore the potential of these compounds against Alzheimer’s disease, their inhibitory activities against acetylcholinesterase (AChE) were evaluated. In this series of compounds, compound 3m, bearing one ethoxy and a hydroxy group on the phenyl ring on 2,4,5-trisubstituted imidazoles, proved to be a potent AChE inhibitor (102.56 +/- 0.14). Structure-activity relationship (SAR) of these compounds was developed. Molecular dockings were carried out for the compounds 3m, 3e, 3k, 3c, 3a, 3d, 3j, and 3f in order to further investigate the binding mechanism. The inhibitor molecule was molecularly docked with acetylcholinesterase to further study its binding mechanism. The amino group of the compound 3m forms an H-bond with the oxygen atom of the residue (i. e., THR121) which has a bond length of 3.051 angstrom.

A one-pot, tandem Wittig hydrogenation of aldehydes with stabilized ylides is reported, representing a formal C(sp(3))-C(sp(3)) bond construction. The tandem reaction operates under mild conditions, is high yielding, and is broad in scope. Chemoselectivity for olefin reduction is observed, and the methodology is demonstrated in the synthesis of lapatinib analogues and a formal synthesis of (+/-)-cuspareine. Early insights suggest that the chemoselectivity observed in the reduction step is due to partial poisoning of the catalyst, after step one, thus adding to the power of the one-pot procedure.

A series of highly active hybrids were discovered as novel antiparasitic agents. Two heterocyclic scaffolds (1,2,4-oxadiazole and 3-hydroxy-2-oxindole) were linked, and the resulting compounds showed in vitro activities against intracellular amastigotes of two protozoan parasites, Tiypanosoma cruzi and Leishmania infantum. Their cytotoxicity was assessed using HFF-1 fibroblasts and HepG2 hepatocytes. Compounds 5b, 5d, 8h and 8o showed selectivity against L. infantum (IC50 values of 3.89, 2.38, 2.50 and 2.85 mu M, respectively). Compounds 4c, 4q, 8a and 8k were the most potent against T. cruzi, exhibiting IC50 values of 6.20, 2.20, 2.30 and 2.20 mu M, respectively. Additionally, the most potent anti-T. cruzi compounds showed in vitro efficacies comparable or superior to that of benznidazole. These easy-to-synthesize molecules represent novel chemotypes for the design of potent and selective lead compounds for Chagas disease and leishmaniasis drug discovery. (C) 2020 Elsevier Masson SAS.

In this study, we synthesize 2-amino-4-alkyl/aryl-6-(hydroxymethyl)-8-oxopyrano[3,2-b] pyran-3-carbonitriles derivatives using a multicomponent reaction featuring aromatic or aliphatic aldehydes, kojic acid, and malononitrile catalyzed by nano fluoroapatite doped with Si and Mg (Si-Mg-FA). All reactions were carried out in EtOH as the solvent under reflux and green condition. The process demonstrates various advantages, including high yields, short reaction times, and simple workup. In addition, toxic organic solvent is not used, nor is chromatographic purification of products required. We characterized the synthesized compounds by Fourier transform infrared,(CNMR)-C-13, and(1)HNMR spectroscopies. Additionally, the antibacterial properties of the pyrano[3,2-b]pyran derivatives were evaluated by determining the minimum inhibitory concentration on two gram-positive and gram-negative bacteria using the macro dilution method and compared with Penicillin and Tetracycline at the same conditions. The 2-amino-4-(2,4-dichlorophenyl)-4,8-dihydro-6-(hydroxymethyl)-8-oxo-pyrano[3,2-b]pyran-3-carbonitrile and the 2-amino-4-hexyl-4,8-dihydro-6-(hydroxymethyl)-8-oxo-pyrano[3,2-b]pyran-3-carbonitrile show the best antibacterial activity with a MIC value of 62.5 mu g/ml againstStaphylococcus aureus(ATCC 25923). Moreover, the antioxidant properties of the pyrano[3,2-b] pyrans derivatives were evaluated. It is notable that pyrano[3,2-b] pyrans derivatives, synthesized with substituent groups on benzaldehyde such as-NO2, -COOCH3, -OMe show the best antioxidant activity measured by DPPH radical-scavenging method.

Chemogenetics enables noninvasive chemical control over cell populations in behaving animals. However, existing small-molecule agonists show insufficient potency or selectivity. There is also a need for chemogenetic systems compatible with both research and human therapeutic applications. We developed a new ion channel-based platform for cell activation and silencing that is controlled by low doses of the smoking cessation drug varenicline. We then synthesized subnanomolar-potency agonists, called uPSEMs, with high selectivity for the chemogenetic receptors. uPSEMs and their receptors were characterized in brains of mice and a rhesus monkey by in vivo electrophysiology, calcium imaging, positron emission tomography, behavioral efficacy testing, and receptor counterscreening. This platform of receptors and selective ultrapotent agonists enables potential research and clinical applications of chemogenetics.

Immobilized piperazine on the surface of graphene oxide (piperazine-GO) is synthesized and characterized by different methods such as FT-IR, solid-state(29)Si{H-1} and(13)C{H-1} CP/MAS NMR, elemental analysis, TGA, TEM, FE-SEM, XPS, and TPD. Subsequently, it is used as a heterogeneous bifunctional acid-base catalyst for the efficient multicomponent reaction of malononitrile, different active compounds containing enolizable C-H bonds and various aryl/alkyl aldehydes in aqueous ethanol. A wide variety of 2-amino-3-cyano-4H-chromenes are synthesized in the presence of this heterogeneous catalyst in good to high yields and with short reaction times. The catalyst is easily separated and reused for at least six times without significant loss of activity. The acidic nature of GO improves the catalytic activity of the supported piperazine and also provides heterogeneity to the catalyst. Use of aqueous ethanol as a green solvent, high turnover numbers (TON), facile catalyst recovery and reuse, simple work-up and generality of the method make this protocol an environmentally benign procedure for the synthesis of the title heterocycles.
