Previous research within our laboratories identified the 3-hydroxypyrrolidine scaffold 1 as a new and selectiveintegrin α5β1 inhibitor class which was designed for local administration. Herein the discovery of new orallyavailableintegrin α5β1 inhibitor scaffolds for potential systemic treatment is described.

oxazoline-substituted potassium organotrifluoroborates was prepared via the condensation of various potassium formyl-substituted aryl- and heteroaryltrifluoroborates with tosylmethyl isocyanide under basic conditions. The efficient Suzuki−Miyaura cross-coupling of products thus formed to various aryl bromides was achieved in good yields. The method allows the facile preparation of oxazole-containing
An aggregation-induced emission (AIE) dye-powered afterglow luminogen has been designed for in vivo tumor imaging. The underlying afterglow mechanism can be described as a closed-loop of “photon–1O2–SP intermediates–photon”.

oxidant, heat, and fuel (organic solvent), are unavoidably present] and environmentally unfriendly. Herein, we report a mild oxidative Suzuki reaction in water using hydrogenperoxide as the terminal oxidant for the first time. The elimination of flammable organic solvents from the reaction prevents possible fires and explosions (starving the solvent) while the use of hydrogenperoxide as the oxidant generates
