Deconstructive Reorganization: De Novo Synthesis of Hydroxylated Benzofuran

An unprecedented deconstructive reorganization strategy for the de novo synthesis of hydroxylated benzofurans from kojic acid- or maltol-derived alkynes is reported. In this reaction, both the benzene and furan rings were simultaneously constructed, whereas the pyrone moiety of the kojic acid or maltol was deconstructed and then reorganized into the benzene ring as a six-carbon component. Through this strategy, at least one free hydroxyl group was introduced into the benzene ring in a substitution-pattern tunable fashion without protection-deprotection and redox adjustment. With this method, a large number of hydroxylated benzofuran derivatives with different substitution-patterns have been prepared efficiently. This methodology has also been shown as the key step in a collective total synthesis of hydroxylated benzofuran-containing natural products (11 examples).

Benzo fury: A new trend in the drug misuse scene

Benzofurans, also known by users as benzo fury or benzofury, are synthetic phenethylamines and constitute the third most prominent group of new psychoactive substances (NPS). As the use of these substances has been spread as an alternative to the classic illicit psychostimulants, such as amphetamines, their legal status was reviewed, resulting in an utter prohibition of these NPS in many countries worldwide. Herein, the prevalence of abuse, chemistry, biological effects, metabolism, and the potential harms and risky behaviors associated with the abuse of benzofurans are reviewed. The congeners of this group are mainly consumed recreationally at electronic dance music parties, in polydrug abuse settings. Benzofurans preferentially act by disturbing the functioning of serotonergic circuits, which induces their entactogenic and stimulant effects and is the reason behind the considerable number of recent benzo fury-related deaths. The slight interaction of these drugs with the dopaminergic system justifies the rewarding effects of these drugs. To date, published evidence on the mechanisms of toxicity of benzo fury is very limited but a body of research is now beginning to emerge revealing an alarming public health threat regarding the abuse of these NPS.

Iron-Catalyzed Functionalization of 3-Benzylideneindoline Through Tandem Csp(2)-Csp(3) Bond Formation/Isomerization with pi-Activated Alcohols

A new synthetic protocol was developed for the selective synthesis of diverse 3-substituted indoles through tandem carbon-carbon bond formation and isomerization of 3-benzylidene-1-tosylindoline by direct use of alcohols as alkylating agents in the presence of catalytic FeCl3. This method is applicable to a wide range of substrates containing varieties of functional groups. Direct use of alcohols, such as benzylic, allylic, and propargylic alcohols, as electrophiles and the use of non-toxic iron catalyst makes this strategy attractive and environmentally benign. A plausible mechanism has also been proposed for this tandem reaction.

Isolation, stereochemical study, and racemization of (+/-)-pratenone A, the first naturally occurring 3-(1-naphthyl)-2-benzofuran-1(3H)-one polyketide from a marine-derived actinobacterium

(+/-)-Pratenone A (1), the first representative of natural 3-(1-naphthyl)-2-benzofuran-1(3H)-one polyketides, was isolated from a marine-derived Streptomyces pratensis strain KCB-132 together with three other new analogues (2-4). Its structure was assigned by spectroscopic analysis, and the absolute configurations of the two enantiomers separated by high-performance liquid chromatography were determined by single-crystal X-ray diffraction and electronic circular dichroism calculations. The solvent-induced racemization of 1 and a proposed biogenetic pathway to 1-4 from the co-isolated angucyclinone precursor, as well as their biological activity, are also discussed.

Development of Radioiodinated Benzofuran Derivatives for in Vivo Imaging of Prion Deposits in the Brain

Prion diseases are fatal neurodegenerative disorders associated with the deposition of abnormal prion protein aggregates (PrPSc) in the brain tissue. Here, we report the development of I-125-labeled iodobenzofuran (IBF) derivatives as single photon emission computed tomography (SPECT) imaging probes to detect cerebral PrPSc deposits. We synthesized and radioiodinated several 5-IBF and 6-IBF derivatives. The IBF derivatives were evaluated as prion imaging probes using recombinant mouse prion protein (rMoPrP) aggregates and brain sections of mouse-adapted bovine spongiform encephalopathy (mBSE)-infected mice. Although all the IBF derivatives were strongly adsorbed on the rMoPrP aggregates, [I-125]5-IBF-NHMe displayed the highest adsorption rate and potent binding affinity with an equilibrium dissociation constant (K-d) of 12.3 nM. Fluorescence imaging using IBF-NHMe showed clear signals of the PrPSc-positive amyloid deposits in the mBSE-infected mouse brains. Biodistribution studies in normal mice demonstrated slow uptake and clearance from the brain of I-125-IBF derivatives. Among the derivatives, [I-125]6-IBF-NH2 showed the highest peak brain uptake [2.59% injected dose (ID)/g at 10 min] and good clearance (0.51% ID/g at 180 min). Although the brain distribution of IBF derivatives should still be optimized for in vivo imaging, these compounds showed prospective binding properties to PrPSc. Further chemical modification of these IBF derivatives may contribute to the discovery of clinically applicable prion imaging probes.

DESIGN, SYNTHESIS AND IN VITRO ANTI-BACTERIAL ACTIVITIES OF BENZOFURAN-ISATIN HYBRIDS

A series of novel benzofuran-isatin hybrids 6a-x tethered through propylene, butylene, pentylene and hexylene were designed, synthesized and evaluated for their in vitro anti-bacterial activities against a panel of clinically important Gram-positive and Gram-negative pathogens including drug-resistant bacteria. All hybrids exhibited decent in vitro anti-bacterial activities, and the most active hybrid 6l was not only comparable to vancomycin against the majority of the tested Gram-positive strains, but also highly active against Gram-negative bacteria. Based on the above results, hybrid 6l could act as a lead for further investigation. Moreover, the enriched structure-activity relationship may pave the way for further optimization.

Spirobiflavonoid stereoisomers from the endangered conifer Glyptostrobus pensilis and their protein tyrosine phosphatase 1B inhibitory activity

Six spirobiflavonoid stereoisomers including two new ones, spiropensilisols A (1) and B (2), were isolated from a mass-limited trunk barks of Glyptostrobus pensilis, an endangered conifer endemic to China. The new structures featuring a benzofuran-containing spirolactone and their absolute configurations were determined by extensive spectroscopic methods. All the isolates showed significant inhibitory activities against the human protein tyrosine phosphatase 1B (PTP1B) enzyme, a potential therapeutic target for diabetes and obesity, with IC50 values ranging from 3.3 to 17.1 mu M. A preliminary SAR analysis with assistance of the molecular modeling approach was performed for the most potent compound (i.e., 1), to understand the nature of interactions governing the binding mode of spirobiflavonids within the active site of the PTP1B enzyme.

Novel tacrine-benzofuran hybrids as potential multi-target drug candidates for the treatment of Alzheimer’s Disease

Pursuing the widespread interest on multi-target drugs to combat Alzheimer ‘ s disease (AD), a new series of hybrids was designed and developed based on the repositioning of the well-known acetylcholinesterase (AChE) inhibitor, tacrine (TAC), by its coupling to benzofuran (BF) derivatives. The BF framework aims to endow the conjugate molecules with ability for inhibition of AChE (bimodal way) and of amyloid-beta peptide aggregation, besides providing metal (Fe, Cu) chelating ability and concomitant extra anti-oxidant activity, for the hybrids with hydroxyl substitution. The new TAC-BF conjugates showed very good activity for AChE inhibition (sub-micromolar range) and good capacity for the inhibition of self- and Cu-mediated A beta aggregation, with dependence on the linker size and substituent groups of each main moiety. Neuroprotective effects were also found for the compounds through viability assays of neuroblastoma cells, after A beta(1-42) induced toxicity. Structure-activity relationship analysis provides insights on the best structural parameters, to take in consideration for future studies in view of potential applications in AD therapy.

Borane-Catalyzed Stereoselective C-H Insertion, Cyclopropanation, and Ring-Opening Reactions

Lewis acidic boranes have been shown to be effective metal-free catalysts for highly selective reactions of donor-acceptor diazo compounds to a range of substrates. The reactions of alpha-aryl alpha-diazoesters with nitrogen heterocycles indole or pyrrole selectively generate C3 and C2 C-H insertion products, respectively, in good to excellent yields even when using unprotected indoles. Alternatively, benzofuran, indene, and alkene substrates give exclusively cyclopropanated products with alpha-aryl alpha-diazoesters, whereas the reactions with furans lead to ring-opening. Comprehensive theoretical calculations have been used to explain the differing reactivities and high selectivities of these reactions. Overall, this work demonstrates the selective metal-free catalytic reactions of alpha-aryl alpha-diazoesters with (hetero)cycles and alkenes. This simple, mild reaction protocol represents an alternative to the commonly used precious metal systems and may provide future applications in the generation of biologically active compounds.
