A boronic acid-based fluorescent probe was developed for diagnosis of amyloid-β (Aβ) plaques from Alzheimer's disease (AD). Probe 4c, which included boronic acid as a functional group, exhibited a significant increase (64.37-fold, FAβ/F0) in fluorescence intensity as a response to Aβ aggregates, with a blue shift (105?nm) in the maximum emission wavelength. We found that boronic acid as a functional group improved the binding affinity (KDvalue?=?0.79?±?0.05?μM for 4c) for Aβ aggregates and confirmed that 4c selectively stained Aβ plaques in brain sections from APP/PS1 mice. Ex vivo fluorescence imaging using mice (normal and APP/PS1) also revealed that 4c was able to penetrate the blood–brain barrier (BBB) and to stain Aβ plaques in the brain. From these results, we believe that 4c will be useful as a fluorescent probe in preclinical research related to AD. Furthermore, we believe that our results with boronic acid also provide valuable information for the development of a probe for Aβ plaques.

Natural products with heteroaromatic cores are ample and widespread in nature, with many compounds exhibiting promising therapeutic properties. (+)-Armillariol C (1a) is a furan-based natural product isolated from Armillaria species. Herein, we report the first enantioselective synthesis of (+)-armillariol C (1a, 79% overall yield), its enantiomer (1b), and four other analogues, on a gram-scale, using microwave-mediated, Suzuki-Miyaura cross-coupling and Sharpless asymmetric dihydroxylation reactions. Compounds were tested for plant- and mycelia-growth regulatory activity, with 1b, 7a, and 7b showing the strongest inhibitory properties in a lettuce assay and 7b and 9b inhibiting Flammulina velutipes.

Increased protein synthesis is a requirement for malignant growth, and as a result, translation has become a pharmaceutical target for cancer. The initiation of cap-dependent translation is enzymatically driven by the eukaryotic initiation factor (eIF)4A, an ATP-powered DEAD-box RNA-helicase that unwinds the messenger RNA secondary structure upstream of the start codon, enabling translation of downstream genes. A screen for inhibitors of eIF4A ATPase activity produced an intriguing hit that, surprisingly, was not ATP-competitive. A medicinal chemistry campaign produced the novel eIF4A inhibitor 28, which decreased BJAB Burkitt lymphoma cell viability. Biochemical and cellular studies, molecular docking, and functional assays uncovered that 28 is an RNA-competitive, ATP-uncompetitive inhibitor that engages a novel pocket in the RNA groove of eIF4A and inhibits unwinding activity by interfering with proper RNA binding and suppressing ATP hydrolysis. Inhibition of eIF4A through this unique mechanism may offer new strategies for targeting this promising intersection point of many oncogenic pathways.

Visible-Light-Mediated Radical Arylation of Anilines with Acceptor-Substituted (Hetero)aryl Halides

supporting information, p. 5976 - 5979 (2017/11/10)
A visible-light-mediated, catalyst-free, direct (hetero)arylation of anilines with mild reaction conditions has been developed. The formation of a donor-acceptor complex between electron-withdrawing substituted (hetero)aryl halides and anilines allows, under blue LED irradiation, the synthesis of ortho and para (hetero)arylated anilines in moderate to good yields. The reaction has a high functional group tolerance. Spectroscopic studies confirmed the donor-acceptor complex formation between aniline and aryl halide.
