We report a new route to the preparation of C-2-symmetrical bivalent phenylboronic acids having alkyl linker groups in the molecule and results of biological evaluation of their biological activity and cytotoxic activity against Vero cells. Among the tested compounds, C-2-symmetrical bivalent meta-oriented phenylboronic acid 2f (n=7) showed high cytotoxic activity (CC50=5.43 mu M) against Vero cells. The results of an SAR study suggested that the presence of a C7-methylene linker group in the molecule is an important structural factor for expression of potential cytotoxic activities. A sugar recognition property of this C-2-symmetrical geometric molecule was suggested by NMR analysis of compound 2f with methyl alpha-D-glucopyranoside 6.
