Abstract

The present invention provides high potency 3,3′-diindolylmethane (DIM) and analogue compounds as antifouling agents. The present invention further provides methods of preventing or reducing settlement and/or fouling of marine fouling organisms on surfaces of submerged objects by coating the surfaces with the 3,3′-diindolylmethane (DIM) and analogue compounds provided.
