Photoaffinity study of the cellular interactions of ilimaquinone.
The marine sponge metabolite ilimaquinone (1) displays a broad range of biological activities. To better understand the effects of this natural product, a photoaffinity analogue was synthesized and used to probe the cellular interactions of ilimaquinone. Irradiation of photoaffinity probe 5 with liver cytosol in the presence and absence of excess competitive inhibitor 2 suggests that S-adenosylhomocysteinase is an important intracellular target of ilimaquinone.
