title: Synthesis and biological activity of 125I/127I-phenylboronic acid derivatives.
abstract: Three iodinated phenylboronic acids have been synthesized: 4-iodophenylboronic acid (2a), 3-(4-iodobenzenesulfonamido)phenylboronic acid (5a) and 3-(5-dimethylamino-6-iodo-1-naphthalenesulfonamido)phenylboronic acid (6a). The corresponding no-carrier-added 125I derivatives 2b, 5b and 6b have been prepared in good yield by selective displacement of the tributylstannyl group. Compound 6b was concentrated in vitro preferentially in HT-29 human colon carcinoma cells compared to V79 Chinese hamster lung fibroblasts and showed selective retention in PaCa-2 human pancreatic cancer cells grown as solid tumor xenografts in the nude mouse.
