The crude extract of Plectranthus Amboinicus (PA) has anti-inflammatory effects and can inhibit AP-1 binding in vitro. The incubation with PA crude extract resulted in significant inhibition of the LPS-induced expression of IL-6, IL-12, MCP-1, and RANTES in HUVEC cells. After the crude extract was further fractionated using preparative HPLC, fraction 8, 9, 10 and 11 were identified to inhibit the AP-1 binding activity. The active component of fraction 8 is Mena 987; fraction 9 is Mena 998; fraction 10 is Mena 9102; and fraction 11 is rosmarinic acid and the synthetic rosmarinic acid analogues. Other compounds showed inhibitory activities as well. These compounds have inhibitory effects on AP-1 activity and are useful as preventive or therapeutic agent for diseases in which excessive expression or activities of AP-1 are involved.
