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.

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).

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.

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.

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.
