5-Aryl-furan derivatives bearing a phenylalanine- or isoleucine-derived rhodanine moiety as potential PTP1B inhibitors

Two series of 5-aryl-furan derivatives bearing a phenylalanine- or isoleucine-derived rhodanine moiety were identified as competitive protein tyrosine phosphatase 1B (PTP1B) inhibitors. Among the compounds studied, 5g was found to have the best PTP1B inhibitory potency (IC50 = 2.66 ± 0.16 μM) and the best cell division cycle 25 homolog B (CDC25B) inhibitory potency (IC50 = 0.25 ± 0.02 μM). Enzymatic data together with molecular modeling results demonstrated that the introduction of a sec-butyl group at the 2-position of the carboxyl group remarkably improved the PTP1B inhibitory activity.

Regioselective palladium-catalyzed arylation of 2-furaldehyde.

An efficient regioselective method for the direct arylation of 2-furaldehyde to provide a range of pi-diverse 5-aryl-2-formylfuran derivatives is described. The method employs functionalized aryl halides and a catalytic amount of palladium(II) chloride under relatively mild conditions.

NMDA receptors mediate glutamatergic neurotransmission and are therapeutic targets due to their involvement in a variety of psychiatric and neurological disorders. Here, we describe the design and synthesis of a series of (R)-3-(5-furanyl)carboxamido-2-am

Novel N-Substituted oseltamivir derivatives as potent influenza neuraminidase inhibitors: Design, synthesis, biological evaluation, ADME prediction and molecular docking studies

The discovery of novel potent neuraminidase (NA) inhibitors remains an attractive approach for treating infectious diseases caused by influenza. In this study, we describe the design and synthesis of novel N-substituted oseltamivir derivatives for probing the 150-cavity which is nascent to the activity site of NA. NA inhibitory studies showed that new derivatives demonstrated the inhibitory activity with IC50 values at nM level against NA of a clinical influenza virus strain. Moreover, the in silico ADME predictions showed that the selected compounds had comparable properties with oseltamivir carboxylate, which demonstrated the druggablity of these derivatives. Furthermore, molecular docking studies showed that the most potent compound 6f and 10i could adopt different modes of binding interaction with NA, which may provide novel solutions for treating oseltamivir-resistant influenza. Based on the research results, we consider that compounds 6f and 10i have the potential for further studies as novel antiviral agents.

Access to Densely Functionalized Chalcone Derivatives with a 2-Pyridone Subunit via Pd/Cu-Catalyzed Oxidative Furan-Yne Cyclization of N -(2-Furanylmethyl) Alkynamides under Air

A protocol for synthesis of chalcone derivatives with a 2-pyridone subunit from N-(2-furanylmethyl) alkynamides is reported. This synthesis involves Pd/Cu-catalyzed oxidative furan-yne cyclization at room temperature in air and may proceed via nucleopalladation of the alkyne to form a vinylpalladium intermediate, with a furan ring acting as the nucleophile.

The present invention provides an in vitro method for identifying a compound that modulates adenosine monophosphate-activated protein kinase (AMPK) for the manufacture of a diagnostic or therapeutic agent. The present invention further provides an assay for identifying a compound that modulates AMPK.

Synthesis and antibacterial evaluation of furan derivatives bearing a rhodanine moiety

Two series of furan derivatives bearing a rhodanine moiety (4a-l and 5a-l) have been synthesized, characterized, and evaluated for their antibacterial activity. The majority of these compounds showed potent levels of inhibitory activity against a variety of different Gram-positive bacteria, including multidrug-resistant clinical isolates, with minimum inhibitory concentration (MIC) values in the range of 2-16 μg/mL. In particular, compound 4l was found to be the most potent of the synthesized compounds against the multidrug-resistant strains, with a MIC value of 2 or 4 μg/mL. None of the compounds exhibited any activity against the Gram-negative bacteria Escherichia coli 1356 at 64 μg/mL. An examination of the cytotoxicities of these agents revealed that they displayed low levels of toxicity toward HeLa cells. All of the compounds synthesized in the current paper were characterized by 1H and 13C NMR, infrared, and mass spectroscopy. Graphical Abstract: Two novel series of furan derivatives bearing a rhodanine moiety were synthesized, and evaluated for their antibacterial activity. Compounds 4l and 5a presented high potency against several multidrug-resistant clinical isolates.[Figure not available: see fulltext.]

Palladium membrane-installed microchannel devices for instantaneous Suzuki-Miyaura cross-coupling

Instantaneous catalytic carbon-carbon bond-forming reactions were achieved in catalytic membrane-installed microchannel devices that have a polymeric palladium-complex membrane. The catalytic membrane-installed microchannel devices were provided inside the microchannels by means of coordinative and ionic molecular convolution at the interface between the organic and aqueous phases flowing laminarly, in which both non-crosslinked linear polymer ligands and palladium species dissolved. The palladium-catalyzed Suzuki-Miyaura reaction of aryl, heteroaryl, and alkenyl halides with arylboronic acids and sodium tetraarylborates was performed with the catalytic membrane-installed microchannel devices to give quantitative yields of biaryls, heterobiaryls, and aryl alkenes within 5 s of residence time in the defined channel region. These microchannel devices were applied to the instantaneous allylic aryla-tion reaction of allylic esters with aryl-boron reagents under microflow conditions to afford the corresponding coupling products within 1 s of residence time.
