Histone modifying proteins, specifically histone deacetylases (HDACs) and bromodomains, have emerged as novel promising targets for anticancer therapy. In the current work, based on available crystal structures and docking studies, we designed dual inhibitors of both HDAC6/8 and the bromodomain and PHD finger containing protein 1 (BRPF1). Biochemical and biophysical tests showed that compounds 23a,b and 37 are nanomolar inhibitors of both target proteins. Detailed structure-activity relationships were deduced for the synthesized inhibitors which were supported by extensive docking and molecular dynamics studies. Cellular testing in acute myeloid leukemia (AML) cells showed only a weak effect, most probably because of the poor permeability of the inhibitors. We also aimed to analyse the target engagement and the cellular activity of the novel inhibitors by determining the protein acetylation levels in cells by western blotting (tubulin vs histone acetylation), and by assessing their effects on various cancer cell lines.
Aromatic Chlorosulfonylation by Photoredox Catalysis

Visible-light photoredox catalysis enables the efficient synthesis of arenesulfonyl chlorides from anilines. The new protocol involves the convenient in situ preparation of arenediazonium salts (from anilines) and the reactive gases SO2and HCl (from aqueous SOCl2). The photocatalytic chlorosulfonylation operates at mild conditions (room temperature, acetonitrile/water) with low catalyst loading. Various functional groups are tolerated (e.g., halides, azides, nitro groups, CF3, SF5, esters, heteroarenes). Theoretical and experimental studies support a photoredox-catalysis mechanism.
Identification of human T2R receptors that respond to bitter compounds that elicit the bitter taste in compositions, and the use thereof in assays to identify compounds that inhibit (block) bitter taste in compositions and use thereof

Page/Page column 144; 145, (2016/02/26)
The present invention relates to the discovery that specific human taste receptors in the T2R taste receptor family respond to particular bitter compounds present in, e.g., coffee. Also, the invention relates to the discovery of specific compounds and compositions containing that function as bitter taste blockers and the use thereof as bitter taste blockers or flavor modulators in, e.g., coffee and coffee flavored foods, beverages and medicaments. Also, the present invention relates to the discovery of a compound that antagonizes numerous different human T2Rs and the use thereof in assays and as a bitter taste blocker in compositions for ingestion by humans and animals.
