Cheng, Yunfeng; Ni, Nanting; Yang, Wenqian; Wang, Binghe published the artcile< A New Class of Fluorescent Boronic Acids That Have Extraordinarily High Affinities for Diols in Aqueous Solution at Physiological pH>, Application of C9H8BNO2, the main research area is fluorescent boronate high affinity diol aqueous solution physiol pH.
The boronic acid group is an important recognition moiety for sensor design. Herein, the authors report a series of isoquinolinylboronic acids that have extraordinarily high affinities for diol-containing compounds at physiol. pH. In addition, 5- and 8-isoquinolinylboronic acids also showed fairly high binding affinities towards D-glucose (Ka=42 and 46 M-1, resp.). For the first time, weak but encouraging binding of cis-cyclohexanediol was found for these boronic acids. Such binding was coupled with significant fluorescence changes. Furthermore, 4- and 6-isoquinolinylboronic acids also showed the ability to complex Me α-D-glucopyranose (Ka=3 and 2 M-1, resp.).
Chemistry – A European Journal published new progress about Affinity. 721401-43-0 belongs to class isoquinoline, and the molecular formula is C9H8BNO2, Application of C9H8BNO2.
