The chromatin reader protein Spindlin1 plays an important role in epigenetic regulation, through which it has been linked to several types of malignant tumors. In the current work, we report on the development of novel analogs of the previously published lead inhibitor A366. In an effort to improve the activity and explore the structure–activity relationship (SAR), a series of 21 derivatives was synthesized, tested in vitro, and investigated by means of molecular modeling tools. Docking studies and molecular dynamics (MD) simulations were performed to analyze and rationalize the structural differences responsible for the Spindlin1 activity. The analysis of MD simulations shed light on the important interactions. Our study highlighted the main structural features that are required for Spindlin1 inhibitory activity, which include a positively charged pyrrolidine moiety embedded into the aromatic cage connected via a propyloxy linker to the 2-aminoindole core. Of the latter, the amidine group anchor the compounds into the pocket through salt bridge interactions with Asp184. Different protocols were tested to identify a fast in silico method that could help to discriminate between active and inactive compounds within the A366 series. Rescoring the docking poses with MM-GBSA calculations was successful in this regard. Because A366 is known to be a G9a inhibitor, the most active developed Spindlin1 inhibitors were also tested over G9a and GLP to verify the selectivity profile of the A366 analogs. This resulted in the discovery of diverse selective compounds, among which 1s and 1t showed Spindlin1 activity in the nanomolar range and selectivity over G9a and GLP. Finally, future design hypotheses were suggested based on our findings.

The cross-coupling study of gem-dibromoesters with triarylbismuths as threefold arylating reagents was investigated under palladium-catalyzed conditions. This study using triarylbismuth reagents explored the cross-coupling reactivity with various functionalized gem-dibromoesters. It furnished a variety of multi-functional trisubstituted acrylates embedded with aryl, alkene and alkyne scaffolds in high yields. The present study in turn, provided easy access to various triarylated acrylates and functionalized 1,3-dienyl and 1,3-enyne esters. Further, the established method applied in the step-economic and convergent synthesis of quebecol natural product in good yield.

Herein we report our results on the anti-inflammatory activity of quebecol, a polyphenolic compound discovered in maple syrup. Bioassays demonstrated that quebecol has an anti-inflammatory effect on LPS-induced NF-κB activation and inhibits the secretion of two pro-inflammatory cytokines, IL-6 and TNF-α. We also prepared and tested precursors of quebecol and its derivatives corresponding to its substructures of interest, with the aim to study the structure-activity relationships. Comparing the results obtained for all tested compounds allowed the identification of the main moiety responsible for the anti-inflammatory activity of quebecol.
Rapid Access to Benzofuran-Based Natural Products through a Concise Synthetic Strategy

, p. 2177 - 2186 (2016/05/09)
A concise strategy is described for the synthesis of ailanthoidol (1), egonol (2), homoegonol (3), demethoxyegonol (4), demethoxyhomoegonol (5), and stemofuran A (6). This approach involves a Pd-catalysed domino cyclization/coupling process using triarylbismuth reagents for the generation of the benzofuran core. Subsequent structural modifications then give the final targets. The high yielding synthesis of the recently isolated natural products egonol-9(Z)-12(Z)-linoleate (2a), 7-demethoxyegonol-9(Z)-12(Z)-linoleate (4a), and 7-demethoxy-egonol-9(Z)-oleate (4b) are also reported.

We report here the total synthesis of quebecol, a new polyphenolic compound with potential applications recently isolated from maple syrup and produced during the condensation of the tree acer saccharum's sap. The synthetic approach we developed involves, as key steps, the formation of a dibromoalkene from an α-ketoester precursor followed by a double Suzuki-Miyaura reaction to unite the three aromatic rings of the target compound on a tetrasubstituted olefin precursor. Our methodology is an efficient pathway to the target compound and leads the way for future analogs.
