WBQ5187, a Multitarget Directed Agent, Ameliorates Cognitive Impairment in a Transgenic Mouse Model of Alzheimer’s Disease and Modulates Cerebral beta-Amyloid, Gliosis, cAMP Levels, and Neurodegeneration

Previously, we designed, synthesized, and evaluated a series of quinolone-benzofuran derivatives as multitargeted anti-Alzheimers disease (anti-AD) compounds, and we discovered that WBQ5187 possesses superior anti-AD bioactivity. In this work, we investigated the pharmacokinetics of this new molecule, as well as its therapeutic efficacy in restoring cognition and neuropathology, in the APP/PS1 mouse model of AD. Pharmacokinetic analyses demonstrated that WBQ5187 possessed rational oral bioavailability, metabolic stability, and excellent blood-brain barrier (BBB) permeability. Pharmacodynamics studies indicated that a 12-week treatment with the lead compound at doses of 40 mg/kg or higher significantly enhanced the learning and memory performance of the APP/PS1 transgenic mice, and the effect was more potent than that of clioquinol (CQ). Furthermore, WBQ5187 notably reduced cerebral beta-amyloid pathology, gliosis, and neuronal cell loss and increased the levels of cAMP in the hippocampus of these mice. The surrogate measures of emesis indicated that WBQ5187 had no effect at its cognitive effective doses. Overall, our results demonstrated that this compound markedly improves cognitive and spatial memory functions in AD mice and represents a promising pharmaceutical agent with potential for the treatment of AD.

Photo- and Redox-active Benzofuran-appended Triphenylamine and Near-infrared Absorption of Its Radical Cation

A triarylamine bearing three benzofuran rings was designed and successfully prepared in 64% yield. It exhibited absorption at 385 nm, and blue emission at around 440nm with a fluorescence quantum yield of 0.57. This compound showed high heat resistance and reversible one-electron oxidation. Upon one-electron chemical oxidation, a near-infrared absorption was revealed due to a persistent radical cation species. DFT calculations also supported the experimental data.

Sulfonate and sulfamate derivatives possessing benzofuran or benzothiophene nucleus as potent carbonic anhydrase II/IX/XII inhibitors

In the current work, we report the discovery of new sulfonate and sulfamate derivatives of benzofuran-and benzothiophene as potent inhibitors of human carbonic anhydrases (hCAs) II, IX and XII. A set of derivatives, 1a-t, having different substituents on the fused benzofuran and benzothiophene rings (R= alkyl, cyclohexyl, aryl, NH2, NHMe, or NMe2) was designed and synthesized. Most of the derivatives exhibited higher potency than acetazolamide as inhibitors of the purified hCAII, IX and XII isoforms. The most potent inhibitors for hCAII, hCAIX and hCAXII were 1g, 1b and 1d with an IC50 +/- SEM values of 0.14 +/- 0.03, 0.13 +/- 0.03 and 0.17 +/- 0.06 mu M, respectively. In addition, compounds 1d and 1n exerted preferential inhibitory effect against hCAXII isozyme with good potencies. Some selected compounds were docked within the active pocket of these isozymes and binding of the molecules revealed that sulfonate and sulfamate rings were located towards the active cavity and compounds coordinated to zinc ions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6296-53-3, in my other articles.

Modern approaches to the synthesis of 3-(acylamino)-and 3-(carbamoylamino)benzofuran-2(3H)-ones (microreview)

The microreview examines modern approaches to the synthesis of 3-(acylamino)- and 3-(carbamoylamino) benzofuran-2(3H)-ones described over the past 10 years (2011-2020). The methods are subdivided into groups depending on the used starting reagents and the reactions underlying them. Approaches based on the use of phenols as starting compounds, methods of modification of benzofuranone derivatives, as well as some other methods are considered.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4412-91-3 is helpful to your research. Name: 3-Furanmethanol.

Bioactive sesquiterpenoids from the flower buds of Tussilago farfara

Eleven new compounds including five bisabolane (1-5) and three oplopane (6-8) sesquiterpenoids, a pair of benzopyran enantiomers (9 & 10) and a benzofuran derivative (11), along with six known sesquiterpenoid cometabolites (12-17), have been obtained from the flower buds of Tussilago farfara. Their structures were elucidated by comprehensive spectroscopic analyses and comparison with structurally related known analogues. The absolute configurations of all the compounds except 11 were unequivocally assigned by various techniques, including Mosher’s method and time-dependent density functional theory (TD-DFT) based calculations of C-13 NMR and electronic circular dichroism (ECD) data. The C-8 absolute configuration on the sidechain of this group of bisabolane sesquiterpenoids was assigned for the first time. Our bioassays have established that compounds 3, 4, 13 and 14 showed significant alpha-glucosidase inhibitory activities, while 6, 8 and 14 displayed moderate antiproliferative effects against two human tumor cell lines A549 and MDA-MB-231. Further flow cytometric analysis revealed that 14 effectively induced cell apoptosis and arrested cell cycle at the S/G2 phases in A549 cells, in a dose-dependent manner.

Directing-Group-Assisted Transition-Metal-Catalyzed Direct C-H Oxidative Annulation of Arenes with Alkynes for Facile Construction of Various Oxygen Heterocycles

The most recent advances in the construction of oxygen heterocycles by the directing-group-assisted transition-metal-catalyzed direct oxidative annulation of arenes with diverse alkynes are summarized in this review. More than 140 recent research papers and many closely related reviews are referenced in this paper. Nine different oxygen heterocycles frameworks are discussed. Several traditional transition-metal catalysts as well as some classical non-noble metals are utilized to promote the annulation. Three plausible controlling models are disclosed to clarify the excellent regioselectivity outcomes achieved in case of unsymmetrical alkyne substrates.

Synthesis and in vitro study of nitro- and methoxy-2-phenylbenzofurans as human monoamine oxidase inhibitors

A new series of 2-phenylbenzofuran derivatives were designed and synthesized to determine relevant structural features for the MAO inhibitory activity and selectivity. Methoxy substituents were introduced in the 2-phenyl ring, whereas the benzofuran moiety was not substituted or substituted at the positions 5 or 7 with a nitro group. Substitution patterns on both the phenyl ring and the benzofuran moiety determine the affinity for MAO-A or MAO-B. The 2-(3-methoxyphenyl)-5-nitrobenzofuran 9 was the most potent MAO-B inhibitor (IC50 = 0.024 mu M) identified in this series, whereas 7-nitro-2-phenylbenzofuran 7 was the most potent MAO-A inhibitor (IC50 = 0.168 mu M), both acting as reversible inhibitors. The number and position of the methoxyl groups on the 2-phenyl ring, have an important influence on the inhibitory activity. Molecular docking studies confirmed the experimental results and highlighted the importance of key residues in enzyme inhibition.
