A strong relationship between abnormal functions of Aurora kinases and tumorigenesis has been reported for decades. Consequently, Aurora kinases serve as potential targets for anticancer agents. Here, we identified aminobenzothiazole derivatives as novel inhibitors of Aurora B kinase through bioisosteric replacement of the previous inhibitors, aminobenzoxazole derivatives. Most of the urea-linked aminobenzothiazole derivatives showed potent and selective inhibitory activity against Aurora B kinase over Aurora A kinase. Molecular modeling indicated that compound 15g bound well to the active site of Aurora B kinase and formed the essential hydrogen bonds. The potent compounds, 15g and 15k, were selected, and their biological effects were evaluated using HeLa cell lines. It was found that these compounds inhibited the phosphorylation of histone H3 at Ser10 and induced G2/M cell cycle arrest. We suggest that the reported compounds have the potential to be further developed as anticancer therapeutics.

We designed, synthesized, and characterized a tri-block copolymer. Its hydrophobic part, a chain of histone deacetylase inhibitor (HDACi) prodrug, was symmetrically flanked by two identical PEG blocks, whereas the built-in HDACi was a linear molecule, terminated with a thiol at one end, and a hydroxyl group at the other. Such a feature facilitated end-to-end linkage of prodrugs through alternatively aligned disulfides and carbonates. The disulfides served dual roles: redox sensors of smart nanomedicine, and warheads of masked HDACi drugs. This approach, carefully designed to benefit both control-release and efficacy, is conceptually novel for optimizing drug units in nanomedicine. Micelles from this designer polyprodrug released only PEG, CO2 and HDACi, and synergized with DOX against HCT116 cells, demonstrating its widespread potential in combination therapy. Our work highlights, for the first time, the unique advantage of thiol-based drug molecules in nanomedicine design.

Preparation of acetals from aldehydes and alcohols under basic conditions
Grabowski, Jakub,Granda, Jaros?aw M.,Jurczak, Janusz
supporting information, p. 3114 - 3120 (2018/05/17)
A new, simple protocol for the synthesis of acetals under basic conditions from non-enolizable aldehydes and alcohols has been reported. Such reactivity is facilitated by a sodium alkoxide along with a corresponding trifluoroacetate ester, utilizing formation of sodium trifluoroacetate as a driving force for acetal formation. The usefulness of this protocol is demonstrated by its orthogonality with various acid-sensitive protecting groups and by good compatibility with functional groups, delivering synthetically useful acetals complementarily to the synthesis under acidic conditions from aldehydes and alcohols.

Palladium-Catalyzed Suzuki–Miyaura Cross-Coupling of Secondary α-(Trifluoromethyl)benzyl Tosylates
Brambilla, Marta,Tredwell, Matthew
supporting information, p. 11981 - 11985 (2017/09/20)
A palladium-catalyzed C(sp3)?C(sp2) Suzuki–Miyaura cross-coupling of aryl boronic acids and α-(trifluoromethyl)benzyl tosylates is reported. A readily available, air-stable palladium catalyst was employed to access a wide range of functionalized 1,1-diaryl-2,2,2-trifluoroethanes. Enantioenriched α-(trifluoromethyl)benzyl tosylates were found to undergo cross-coupling to give the corresponding enantioenriched cross-coupled products with an overall inversion in configuration. The crucial role of the CF3 group in promoting this transformation is demonstrated by comparison with non-fluorinated derivatives.
