Efficient synthesis of (+/-)-parasitenone, a novel inhibitor of NF-kappaB.
Dehydroxymethylepoxyquinomicin (DHMEQ, 1) is a novel nuclear factor-kappaB (NF-kappaB) inhibitor that inhibits DNA binding of NF-kappaB components including p65. To inspect its biological activity of 1, we synthesized parasitenone (3), possessing the common epoxycyclohexenone moiety of 1. Assessment of the inhibitory activity against NF-kappaB indicated that the epoxycyclohexenone moiety is the most essential element for the NF-kappaB inhibitory activity and the salicylic acid moiety may contribute the binding efficiency and specificity.
