PREPARATION AND CYTOTOXIC EVALUATION OF VOUACAPANE OXIDATION PRODUCTS

Treatment of (-)-(5S,6R,8S,9S,10R,14R)-6-acetoxyvouacapane (1) with DDQ, mCPBA, or Cr(VI) reagents afforded diterpenoids with various degrees of oxidation at the furan and C rings. Oxidation of 1 using DDQ provided the known benzofuran 2, together with the new derivatives dimer 3, lactone 4, and aldehyde 5, while mCPBA oxidation gave 2, spirocassenolide 6, and cassenolides 7 and 8a. Oxidation of 1 with CrO3 gave 4, 6, 8a, and spirocassenolide 9, while the use of K2Cr2O7 yielded 4, 9, and spirocassenolide 10.

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.

Tandem Synthesis of 2-Carboxybenzofurans via Sequential Cu-Catalyzed C-O Coupling and Mo(CO)(6)-Mediated Carbonylation Reactions

A modular tandem synthesis of 2-carboxybenzofurans from 2-gem-dibromovinylphenols has been established based on a sequence of Cu-catalyzed intramolecular C-O coupling and Mo(CO)(6)-mediated intermolecular carbonylation reactions. This protocol allowed one-step access to a broad variety of functionalized benzofuran-2-carboxylic acids, esters, and amides in good to excellent yields under Pd- and CO gas-free conditions.

Synthetic enhancer compounds, besides acting on biogenic amine system, influence the glutamate transmission and stress response

Pharmaceutically available enhancer selegiline/(-)-deprenyl (DEP) in the clinically used dose shows antidepressant effect, but nothing is known about this effect in enhancer dose, and its effect on co-morbid anxiety. Moreover, data about the antidepressant/antianxiety effects of the serotonin-influencing enhancer, (2R)-1-(1-benzofuran-2-yl)-N-propylpentane-2-amine (BPAP) are also missing. The aim of the present paper is to establish the role of enhancer regulation in anxiety and follow the changes in the phosphorylation of glutamate subunits in prefrontal cortex as well as stress-related organ and hormonal changes as possible background mechanism. The effect of 3-week-treatment of rats with specific (0.001 mg/kg for DEP, 0.0001 mg/kg for BPAP) and non-specific (0.1 mg/kg for DEP, 0.05 mg/kg for BPAP) enhancer doses were evaluated on anxiety-like behavior in the elevated plus maze (EPM) and open-field (OF) tests. Phosphorylated glutamatergic GluR1 and GluN2B subunits were analyzed by Western blot. Changes in the stress-regulatory system were evaluated by measuring the organ weights and blood corticosterone concentrations. Non-specific enhancer doses had a tendency for anxiolysis on EPM, while only 0.1 mg/kg DEP elevated motility in OF. Specific enhancer doses significantly increased the expression of both glutamatergic receptor subunits; non-specific doses elevated only pGluR1. Treatments had no effects on stress-like organ weights; however, the specific enhancer doses significantly reduced the dark phase resting corticosterone levels. The study proved the enhancer-sensitivity of the glutamatergic transmitter system and suggested enhancer-induced stabilization of stress-hormone levels without major impact on non-stimulated anxiety-like behavior.

Probing 2-acetylbenzofuran hydrazones and their metal complexes as alpha-glucosidase inhibitors

Inhibition of alpha-glucosidase is one of the important approaches in designing antidiabetic drugs for its role in decrease of the carbohydrates digestion to avoid post-prandial increase in blood sugar levels in diabetic patients. In the present study we designed a novel series of 2-acetylbenzofuran hydrazones (L1-L7) and their metal (II) complexes Cu (II), Co (II), Zn (II) and Mn (II) (8-29) and screened for inhibitory activity against the yeast alpha-glucosidase. The synthesis of hydrazones incorporated the use of I-2 as a catalyst which resulted in excellent yield of 94%. The ligand L3, showed good activity (IC50 = 47.51 +/- 0.86 mu M) while its metal complex (10) showed potent activity (IC50 = 1.15 +/- 0.001 mu M) compared to reference acarbose IC50 = 378.25 +/- 0.12 mu M. Similarly, the Cu (II) complexes with ligands L5 and L6 showed excellent alpha-glucosidase inhibition (IC50 = 0.15 +/- 0.003 12 and 0.21 +/- 0.002 mu M for 13, respectively) whereas, the metal complexes of Co (II), Mn (II), and Zn (II) showed moderate to poor inhibitory activities against alpha-glucosidase. The The findings are supported by the ligands and enzyme interactions through molecular docking studies. In conclusion, it is indicated that metal complexes of 2-acetylbenzofuran hydrazones have good potential for research leading to antidiabetic therapies.
