Abstract

Hydroxylated polychlorinated biphenyls (PCBs) have been identified in wildlife and human samples. Most of these compounds are highly chlorinated (penta-hepatachloro) and contain a single meta- or para-hydroxyl group. Using the Cadogan coupling procedure, the following hydroxy-PCBs congeners were synthesized: 2,3,3′,4′,5- pentachloro-4-biphenylol, 2,3′,4,4′,5-pentachloro-3-biphenylol, 2′,3,3′,4′,5-pentachloro-4-biphenylol, 2,2′,3′,4,4′-pentachloro-3-biphenylol, 2,2′,3,3′,4′,5-pentachloro-4-biphenylol, 2,2′,3′,4,4′,5-hexachloro-3-biphenylol, 2,2′,3,4′,5,5′-hexachloro-4-biphenylol, 2,2′,3,3′,4′,5,5′-heptachloro-4-biphenylol, 2,2′,3′,4,4′,5,5′-heptachloro-3-biphenylol, 2,2′,3,4′,5,5′,6-heptachloro-4-biphenylol. Many of these compounds have been detected as residues in human serum and current studies are investigating their activities as agonists and antagonists for several endocrine-mediated responses.
