Precocene II is a cyclic propenylic plant metabolite and asarone analog. It shows antijuvenile hormone activity in insects and inhibits trichothecene production in fungi. Precocene II showed strong hepatotoxic, nephrotoxic and hepatocarcinogenic activity. Precocene II exhibited inhibitory activity on the P-388 cancer cell line and the HT-29 cancer cell line. It is a bioactive component of Ageratum houstonianum, responsible for circadian CLOCK-mediated up-regulation of AQP3 in human keratinocytes. It can be used as a potential adjunct to enhance the treatment of various skin diseases by providing adequate hydration in the epidermis.
