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.

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.

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.

Agmatine Protects Against the Progression of Sepsis Through the Imidazoline I-2 Receptor-Ribosomal S6 Kinase 2-Nuclear Factor-kappa B Signaling Pathway

Objectives: The knowledge that agmatine is found in the human body has existed for several years; however, its role in sepsis has not yet been studied. In the present study, we investigate the role of agmatine in the progression and treatment of sepsis. Design: Clinical/laboratory investigations. Setting: Medical centers/University-based research laboratory. Subjects: Elective ICU patients with severe sepsis and healthy volunteers; C57BL/6 mice weighing 18-22 g. Interventions: Serum agmatine level and its associations with inflammatory markers were assessed in patients with sepsis. Agmatine was administered intraperitoneally to mice before a lipopolysaccharide challenge. Human peripheral blood mononuclear cells and murine macrophages were pretreated with agmatine followed by lipopolysaccharide stimulation. Measurements and Main Results: Serum agmatine levels were significantly decreased in patients with sepsis and lipopolysaccharide-induced mice, and correlated with Acute Physiology and Chronic Health Evaluation II score, procalcitonin, tumor necrosis factor-alpha, and interleukin-6 levels. In a therapeutic experiment, exogenous agmatine attenuated the cytokine production of peripheral blood mononuclear cells from patients with sepsis and healthy controls. Agmatine also exerted a significant beneficial effect in the inflammatory response and organ damage and reduced the death rate in lipopolysaccharide-induced mice. Imidazoline I-2 receptor agonist 2-benzofuran-2-yl blocked the pharmacological action of agmatine; whereas, other imidazoline receptor ligands did not. Furthermore, agmatine significantly impaired the inflammatory response by inactivating nuclear factor-kappa B, but not protein 38 mitogen-activated protein kinase, c-Jun N-terminal kinase, extracellular signal-regulated kinase, and inducible nitric oxide synthase signaling in macrophages. Activation of imidazoline I-2 receptor or knockdown of ribosomal S6 kinase 2 counteracted the effects of agmatine on phosphorylation and degradation of inhibitor of nuclear factor-kappa B alpha. Conclusions: Endogenous agmatine metabolism correlated with the progression of sepsis. Supplemental exogenous agmatine could ameliorate the lipopolysaccharide-induced systemic inflammatory responses and multiple organ injuries through the imidazoline I-2 receptor-ribosomal S6 kinase 2-nuclear factor-kappa B pathway. Agmatine could be used as both a clinical biomarker and a promising pharmaconutrient in patients with severe sepsis.

Iridium-Catalyzed Intramolecular Cycloisomerization between Functionalized Alkyne with Aryl Vinyl Ether: Synthesis of 2-Vinyl-3-functionalized Methylbenzofurans

We have developed cycloisomerization between an aryl vinyl ether and a functionalized alkyne, such as silylalkyne, to give 2,3-disubstituted benzofuran derivatives using [IrCl(cod)](2), PCy3, and NaBAr4F. This catalyst system not only catalyzes the above cycloisomerization but also isomerize a terminal olefin to give an aryl vinyl ether.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 4412-91-3. Category: benzofurans.

Copper-Catalyzed C-H Difluoroalkylation of Coumarins with Fluoroalkyl Bromides

An efficient method for the copper-catalyzed selective C-H difluoroalkylation of coumarins and with low cost and readily available ethyl bromodifluoroacetate andN-phenyl bromodifluoroacetamide has been reported. This reaction exhibits good functional group tolerance with respect to coumarins and difluoroalkylation reagents, and several redox-sensitive substrates have been successfully C-H difluoroalkylated in good to high yield. This design could further expand the scope to other heteroarenes, including furan, benzofuran, pyrrole, pyridinone, chromenone, indole, and quinolinone. A mechanism involving copper-catalyzed in-situ generation of fluoroalkyl radical is proposed.

Expanding the chemical space: Discovery of new anticancer3-arylbenzofuranderivatives

A new chemical space was generated via C-2-functionalization of 3-arylbenzofurans. Mannich reaction of 3-arylbenzofurans with secondary amines and formaldehyde allowed for installation of aminomethyl unit at C(2)position of benzofurans. A formyl group at C(2)site introduced as a result of Vilsmeier-Haack formylation of 3-arylbenzofurans was employed as a reacting partner for three-component Kabachnik-Fields reaction with various amines and triethyl phosphite to give a wide variety of aminomethylphosphonates. Furthermore, several benzo[d]oxazoles and pyrrolo[1,2-a]quinoxalines were prepared by using the formyl group. Biological screening of the synthesized compounds revealed that the benzofuran bearing a pyrrolo[1,2-a]quinoxaline moiety (5b) most potently inhibited the viability of human blood cancer cells, but not solid tumor cells. Caspase activity assay, analysis of Annexin V-positive cells, and Western blot analysis indicated that5b-induced death of human lymphoma U937 cells could result from its potential to induce the caspase-dependent apoptotic death of blood cancer cells with inhibition of ERK activation.
