Synthesis and Anticancer Activity of New ((Furan-2-yl)-1,3,4-thiadiazolyl)-1,3,4-oxadiazole Acyclic Sugar Derivatives

New sugar hydrazones incorporating furan and/or 1,3,4-thiadiazole ring systems were synthesized by reaction of the corresponding hydrazide with different aldose sugars. Heterocyclization of the formed hydra zones afforded the derived acyclic nucleoside analogues possessing the 1,3,4-oxadiazoline as modified nucleobase via acetylation followed by the heterocyclization process. The anticancer activity of the synthesized compounds was studied against human liver carcinoma cell (HepG-2) and at human normal retina pigmented epithelium cells (RPE-1). High activities were revealed by compounds 3, 12 and 14 with IC50 values near to that of the reference drug doxorubicin.

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.

Synthesis, In Vitro Evaluation and Molecular Docking of the 5-Acetyl-2-aryl-6-hydroxybenzo[b]furans against Multiple Targets Linked to Type 2 Diabetes

The 5-acetyl-2-aryl-6-hydroxybenzo[b]furans 2a-h have been evaluated through in vitro enzymatic assay against targets which are linked to type 2 diabetes (T2D), namely, alpha-glucosidase, protein tyrosine phosphatase 1B (PTP1B) and beta-secretase. These compounds have also been evaluated for antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging method. The most active compounds against alpha-glucosidase and/or PTP1B, namely, 4-fluorophenyl 2c, 4-methoxyphenyl 2g and 3,5-dimethoxyphenyl substituted 2h derivatives were also evaluated for potential anti-inflammatory properties against cyclooxygenase-2 activity. The Lineweaver-Burk and Dixon plots were used to determine the type of inhibition on compounds 2c and 2h against alpha-glucosidase and PTP1B receptors. The interactions were investigated in modelled complexes against alpha-glucosidase and PTP1B via molecular docking.

Alkoxyphenyl or alkylphenyl side-chained Thieno[2,3-f]benzofuran polymer for efficient non-fullerene solar cells

In this work, two novel thieno[2,3-f]benzofuran (TBF) unit, with fluorinated alkoxyphenyl or alkylphenyl side chain, were synthesized and characterized. Based on these TBF donor unit and benzodithiophene-4,8-dione (BDD) acceptor, two novel polymers, PTBFPF-BDD and PTBFP-BDD, were prepared by Stille coupling reaction. The conjugated side chain effects on the thermogravimetric, optical, electrochemical, and photovoltaic properties of these polymers were systematically investigated. Both polymers exhibited desirable power conversion efficiency (PCE) of more than 8% after thermal annealing. PTBFP-BDD:ITIC-based devices achieved higher PCE of 8.50% with an open-circuit voltage (V-OC) of 0.88 V, a short-circuit current density (J(SC)) of 16.01 mA/cm(2) and a fill factor (FF) of 59.80%. In addition, the devices based on PTBFPF-BDD:ITIC showed an enhanced V-OC of 0.92 V due to down-shifted the highest occupied molecular orbital (HOMO) energy levels. The results indicate that the alkylphenyl/alkoxyphenyl substitution of TBF donor units is promising strategy for improving PCE of PSCs. (C) 2020 Elsevier Ltd. All rights reserved.

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, Antimicrobial Evaluation, and Laccase Catalysis Effect of Novel Benzofuran-Oxadiazole and Benzofuran-Triazole Hybrids

Novel structural hybrids of benzofuran-oxadiazole and benzofuran-triazole have been synthesized and evaluated for their potential against Staphylococcus aureus, Bacillus subtilis, and Escherichia coli. The excellent antibiotic activity was shown by compounds 5c and 9c against S. aureus with minimum inhibitory concentration values in 1.74-5.16 mg/mL range. The estimation of in vitro antifungal activity of synthetic compounds was performed against Trichoderma harzianum, Aspergillus niger, and Metarhizium anisopliae. Among compounds 5a-5j, only 5h and 5i showed promising antifungal potential against T. harzianum and A. niger, whereas compound 5j showed enhanced antifungal effect only against A. niger when their activity values were compared with standard drug amphotericin. No pronounced antifungal activity was shown by synthesized compounds 9a-j, except for compound 9g, which was active against all fungal strains having minimum inhibitory concentration values in 1.90-2.03 mg/mL range. In addition to antimicrobial evaluation, the synthesized compounds were also analyzed to study their effects on the catalytic potential of laccase, and it was found that among all, compound 9b showed very strong activity with maximum relative reactivity of 145% at 0.03-mM concentration.

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.

Electrospray ionization tandem mass spectrometry of deprotonated dihydrobenzofuran neolignans

Rationale Although dihydrobenzofuran neolignans (DBNs) display a wide diversity of biological activities, the identification of their in vivo metabolites using liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) remains a challenge to be overcome. Recently, ESI-MS/MS data of protonated DBNs have been reported, but they were shown to be limited due to the scarcity of diagnostic ions. Methods The gas-phase fragmentation pathways of a series of biologically active synthetic benzofuran neolignans (BNs) and DBNs were elucidated by means of negative ESI accurate-mass tandem and sequential mass spectrometry, and thermochemical data estimated using computational chemistry and the B3LYP/6-31+G(d,p) model. Results Deprotonated DBNs produced more diagnostic product ions than the corresponding protonated molecules. Moreover, a series of odd-electron product ions (radical anions) were detected, which has not been reported for protonated DBNs. Direct C2H3O2 center dot elimination from the precursor ion (deprotonated molecule) only occurred for the BNs and can help to distinguish these compounds from the DBNs. The mechanism through which the [M – H – CH3OH](-) ion is formed is strongly dependent on specific structural features. Conclusions The negative ion mode provides much more information than the positive ion mode (at least one diagnostic product ion was detected for all the analyzed compounds) and does not require the use of additives to produce the precursor ions (deprotonated molecules).
