- Palladium-Catalyzed Tandem Carbonylative Diels-Alder Reaction for Construction of Bridged Polycyclic Skeletons
-
A palladium-catalyzed tandem carbonylative lactonization and Diels-Alder cycloaddition reaction between aldehyde-tethered benzylhalides and alkenes has been developed. A range of alkenes and aldehyde-tethered benzylhalides bearing different substituents can be successfully transformed into the corresponding bridged polycyclic compounds in good yields. This strategy provides a unique approach to complex lactone-containing bridged polycyclic compounds.

- Copper-promoted direct amidation of isoindolinone scaffolds by sodium persulfate
-
Isoindolinones are ubiquitous structural motifs in natural products and pharmaceuticals. Establishing an efficient method for structural modification of isoindolinones could significantly facilitate new drug development. Herein, we describe copper-promoted direct amidation of isoindolinone scaffolds mediated by sodium persulfate. The method exhibits mild reaction conditions and high site-selectivity, and enables the structural modification of the drug indobufen ester with various amides with yields of 49 to 98%. It is also gram-scalable. Additionally, the reaction mechanism appears to involve a radical and a carbocationic pathway.

- Br?nsted Acid Catalyzed Dearomatization by Intramolecular Hydroalkoxylation/Claisen Rearrangement: Diastereo- and Enantioselective Synthesis of Spirolactams
-
Described herein is a novel Br?nsted acid catalyzed intramolecular hydroalkoxylation/Claisen rearrangement, allowing the practical and atom-economic synthesis of a range of valuable spirolactams from readily available ynamides in generally good to excellent yields with excellent diastereoselectivities and broad substrate scope. Importantly, an unexpected dearomatization of nonactivated arenes and heteroaromatic compounds is involved in this tandem sequence. Moreover, an asymmetric version of this tandem cyclization was also achieved by efficient kinetic resolution by chiral phosphoric acid catalysis. In addition, the [3,3]-rearrangement is shown to be kinetically preferred over the related [1,3]-rearrangement by theoretical calculations.

- Assessment of the regioselectivity in the condensation reaction of unsymmetrical o-phthaldialdehydes with alanine
-
One approach for the synthesis of isoindolinones, a privileged bioactive heterocyclic core structure, involves a condensation reaction of o-phthaldialdehydes with a suitable nitrogen-containing nucleophile. This fascinating reaction is revisited here in the context of the use of o-phthaldialdehydes that contain additional substituents in the aromatic ring leading to a detailed analysis of the regioselectivity of the reaction. Eleven monosubstituted o-phthaldialdehydes were synthesised and reacted with alanine. The regioselectivity observed across the eleven substrates led to the design of a disubstituted substrate that reacted with very high control. A gram-scale reaction followed by esterification gave one major regioisomer in high yield. In addition, the regioselectivity observed on reaction of two novel monodeuterated substrates led to an increased mechanistic understanding.

- Development of Novel Inhibitors for Histone Methyltransferase SET7/9 based on Cyproheptadine
-
The histone methyltransferase SET7/9 methylates not only histone but also non-histone proteins as substrates, and therefore, SET7/9 inhibitors are considered candidates for the treatment of diseases. Previously, our group identified cyproheptadine, used clinically as a serotonin receptor antagonist and histamine receptor (H1) antagonist, as a novel scaffold of the SET7/9 inhibitor. In this work, we focused on dibenzosuberene as a substructure of cyproheptadine and synthesized derivatives with various functional groups. Among them, the compound bearing a 2-hydroxy group showed the most potent activity. On the other hand, a 3-hydroxy group or another hydrophilic functional group such as acetamide decreased the activity. Structural analysis clarified a rationale for the improved potency only by tightly restricted location and type of the hydrophilic group. In addition, a SET7/9 loop, which was only partially visible in the complex with cyproheptadine, became more clearly visible in the complex with 2-hydroxycyproheptadine. These results are expected to be helpful for further structure-based development of SET7/9 inhibitors.

- Metabolically stable dibenzo[ b, e ]oxepin-11(6 H)-ones as highly selective p38 MAP kinase inhibitors: Optimizing anti-cytokine activity in human whole blood
-
Five series of metabolically stable disubstituted dibenzo[b,e]oxepin-11(6H) -ones were synthesized and tested in a p38α enzyme assay for their inhibition of tumor necrosis factor-α (TNF-α) release in human whole blood. Compared to the monosubstituted dibenzo[b,e]oxepin-11(6H)-one derivatives, it has been shown that the additional introduction of hydrophilic residues at position 9 leads to a substantial improvement of the inhibitory potency and metabolic stability. Using protein X-ray crystallography, the binding mode of the disubstituted dibenzoxepinones and the induction of a glyince flip in the hinge region were confirmed. The most potent compound of this series, 32e, shows an outstanding biological activity on isolated p38α, with an IC50 value of 1.6 nM, extraordinary selectivity (by a factor >1000, Kinase WholePanelProfiler), and low ATP competitiveness. The ability to inhibit the release of TNF-α from human whole blood was optimized down to an IC50 value of 125 nM. With the promising dibenzoxepinone inhibitor 3i, a pharmacokinetic study in mice was conducted.
