Spirodesertols A and B, two highly modified spirocyclic diterpenoids with an unprecedented 6-isopropyl-3H-spiro[benzofuran-2,1 ‘ cyclohexane] motif from Salvia deserta

Two highly modified spirocyclic diterpenoids with an unprecedented 6-isopropyl-3H-spiro[benzofuran2,1’-cyclohexane] motif, spirodesertols A (1) and B (2), four new icetexane diterpenoids, salviadenones A-D (3-6), together with their biogenetic precursor, 20-deoxocarnosol (7), were isolated from the root extract of Salvia deserta. Their structures were elucidated by spectroscopic analysis, quantum chemical calculations including the 13C chemical shift calculations with DP4+ probability analysis and electronic circular dichroism (ECD) calculations, and single-crystal X-ray diffraction analysis. The plausible biogenetic pathways for 1-6 were proposed. Compounds 1-7 were evaluated for their cytotoxicity against five cancer cell lines. Spirodesertol A (1) showed more potent cytotoxicity against the A-549, SMMC-7721, and MCF-7 cancer cell lines than the positive control, cisplatin.

Insights into serotonergic and antioxidant mechanisms involved in antidepressant-like action of 2-phenyl-3-(phenylselanyl)benzofuran in mice

Monoaminergic and oxidative dysfunctions have been reported to play a role in depression. The present study investigated the antioxidant potential as well as the antidepressant-like action of 2-phenyl-3-(phenylselanyl) benzofuran (SeBZF1) in male Swiss mice. Time and dose-response curves were analyzed with the forced swim (FST) and tail suspension (TST) tests, in which SeBZF1 elicited antidepressant-like effects. Serotonergic mechanisms were investigated in the TST. The pre-administration of WAY100635 (selective 5-HT1A receptor antagonist, 0.1 mg/kg, subcutaneous route), ketanserin (5-HT2A/2C receptor antagonist, 1 mg/kg, intraperitoneal route, i.p.), and chlorophenylalaninemethyl ester (p-CPA) (selective tryptophan hydroxylase inhibitor, 100 mg/kg, i.p., for 4 days), but not of ondansetron (selective 5-HT3 receptor antagonist, 1 mg/kg, i.p.), abolished the antidepressant-like action of SeBZF1 (50 mg/kg, intragastric route, i.g.). Co-administration of sub-effective doses of SeBZF1 (1 mg/kg, i.g.) and fluoxetine (5 mg/kg, i.p., selective serotonin reuptake inhibitor) was effective in producing anti-immobility effects in the TST, revealing a synergistic effect. Besides, p-CPA induced hippocampal oxidative stress, characterized by a reduction of total thiols and lipoperoxidation, which was reversed by SeBZF1 (50 mg/kg). The in vitro screening of the antioxidant action of SeBZF1 in brain tissue reinforced these results. Lastly, SeBZF1 did not cause systemic toxicity at a high dose (300 mg/kg). In summary, the present study demonstrated that SeBZF1 exerted antidepressant-like action in male mice which appears to be mediated by the serotonergic system. Moreover, SeBZF1 elicited in vitro antioxidant action in brain tissue, attenuated the hippocampal oxidative damage induced by 5-HT depletion in mice and showed no toxic signs.

QSAR Modeling and Drug-Likeness Screening for Antioxidant Activity of Benzofuran Derivatives

In order to explore the relationship between the antioxidant activity and structure of fifteen benzofuran derivatives, we carried out a QSAR study using multiple linear regression (MLR) and artificial neural network (ANN) methods. Six descriptors were used as input data (molar weight, surface area, octanol-water partition coefficient, hydration energy, highest occupied molecular orbital energy and lowest unoccupied molecular orbital energy). The electronic properties were derived at the B3LYP/6-31 G (d,p) level. Benchmarks on furan and benzofuran subunits and their comparison to the experiment showed that this level of theory is good enough. The output data correspond to the antioxidant activity as given by IC50. The predicted properties are in agreement with experimental values. Our study shows that 80% of studied molecules are in accordance with the Lipinski and Veber rules and reach the optimal lipophilicity indices. In addition, statistical analysis reveals that ANN technique with (6-2-1) architecture is more significant than MLR model. (C) 2019 Elsevier B.V. All rights reserved.

Tailoring a stable and recyclable nanobiocatalyst by immobilization of surfactant treated Burkholderia cepacia lipase on polyaniline nanofibers for biocatalytic application

Polyaniline nanofibers were synthesized by the oxidative polymerization of aniline. Surfactant treated lipase from Burkholdaria cepacia was immobilized on these polyaniline nanofibers by adsorption. The activity of immobilized preparation was six times higher than that of free lipase with an enhanced dispersion in organic sol- vents. Five-level-four-factor central composite design was applied for the optimization of immobilization parameters (viz. reaction time, pH, stirring rate and enzyme-support ratio) which were evaluated on the basis of lipase loading and activity. The thermal stability of the lipase in the nanobioconjugate, demonstrated in terms of the half-life at 80 degrees C was almost sixteen-fold higher than in the free form. The reusability data revealed the utility of the nanoconjugate for seven consecutive cycles with a slow and gradual decline in the activity. However, the nanoconjugate retained almost 30% of their initial activity after seven cycles of reuse revealing its utility of in industrial applications. The nanoconjugate was used in the kinetic resolution of (RS)-1-(7-(3-chloro-2-hydroxypropoxy)benzofuran-2-yl) ethanone, racemic intermediate of an important beta-blocker (Befunolol), with a high conversion rate of 48.2%, 98% ee-value and enantioselectivity (E) of 188, which signify its importance as a nanobiocatalyst.

In vitro toxicokinetics and analytical toxicology of three novel NBOMe derivatives: phase I and II metabolism, plasma protein binding, and detectability in standard urine screening approaches studied by means of hyphenated mass spectrometry

Purpose Toxicokinetic studies are essential in clinical and forensic toxicology to understand drug-drug interactions, influence of individual polymorphisms, and elimination routes, as well as to evaluate targets for toxicological screening procedures. N-(2-Methoxybenzyl)-substituted phenethylamines (NBOMe analogues) intake has been associated with severe adverse reactions including deaths. 1-(1-Benzofuran-5-yl)-N-[(2-methoxyphenyl)methyl]propan-2-amine (5-APB-NBOMe), 2-(8-bromo-2,3,6,7-tetrahydrobenzo[1,2-b:4,5-b ‘]difuran-4-yl)-N-[(5-chloro-2-ethoxyphenyl)methyl]ethan-1-amine (2C-B-FLY-NB2EtO5Cl), and 2-(8-bromo-2,3,6,7-tetrahydrobenzo[1,2-b:4,5-b ‘]difuran-4-yl)-N-[(2-methoxyphenyl)methyl]ethan-1-amine (2C-B-FLY-NBOMe) are three emerging NBOMe analogues, which have encountered on the drugs of abuse market. So far, their toxicokinetic data are completely unexplored. Methods The study included mass spectrometry-based identification of phase I and II metabolites following exposure to the terminally differentiated human hepatocellular carcinoma cells (HepaRG). The determination of enzymes involved in the major phase I/II metabolic steps and determination of plasma protein binding (PPB) were done. Finally, the evaluation of the toxicological detectability by different hyphenated mass spectrometry techniques in standard urine screening approaches (SUSAs) was investigated. Results The compounds were extensively metabolized in HepaRG cells mainly via O-dealkylation, hydroxylation, glucuronidation, and combinations thereof. CYP1A2, 2D6, 2C8, 2C19, and 3A4, were involved in the initial reactions of all investigated compounds. Glucuronidation of the phase I metabolites-when observed-was mainly catalyzed by UGT1A9. The PPB of all compounds was determined to be > 85%. Only the high-resolution mass spectrometry-based SUSA allowed detection of all compounds in rat urine, but only via metabolites. Conclusions The toxicokinetic data provided by this study will help forensic and clinical toxicologists to reliably identify these substances in case of abuse and/or intoxication and will allow them a thorough risk assessment.

Crystalline and Stable Benzofuran-Linked Covalent Organic Frameworks from Irreversible Cascade Reactions

We report the synthesis of crystalline two-dimensional covalent organic frameworks (COFs) by connecting hydroxybenzene-aldehyde and acetonitrile building blocks to form cyano-substituted benzofuran linkages. Unlike the majority of COFs that were synthesized based on condensation reactions, the COFs in this report are crystallized from irreversible cascade reactions involving consecutive cyanide migration, ring-closure, and oxidation reactions. The irreversible property endows the COFs with high chemical stability in both acid and base and allows them to be postsynthetically modified to install predesigned functionality under harsh conditions. We highlight that the functionalized COFs serve as exceptional vehicles for superprotonic conductions.

Effect of chemical structure of benzofuran derivatives and reaction conditions on enantioselective properties of Aureobasidium pullulans microorganism contained in Boni Protect antifungal agent

Bioorganic asymmetric reduction of carbonyl compounds is one of the most important fundamental and practical reactions for producing chiral alcohols. The stereoselective bioreduction of prochiral ketones of benzofuran derivatives in the presence of yeast-like fungus Aureobasidium pullulans contained in the antifungal Boni Protect agent was studied. Biotransformations were carried out under moderate conditions in an aqueous and two-phase system and without multiplication of the bioreagent. Despite similar chemical structure, each of the used ketone has been reduced with varying efficiency and selectivity. One of the reasons for these results is the presence of a whole set of oxidoreductases in A. pullulans cells that are sensitive to the smallest changes in the structure of prochiral substrate. The unsymmetrical methyl ketones were biotransformed with the highest selectivity. Aureobasidium pullulans microorganism is less effective in the reduction of unsymmetrical halomethyl ketones. The presence of a heteroatom in the alkyl group significantly decreases the selectivity of the process. Finally, as a result of the preferred hydride ion transfer from the dihydropyridine ring of the cofactor to the carbonyl double bond on the re side, secondary alcohols of the S and R configuration were obtained with moderate to high enantioselectivity (55-99%).
