Chymacyparis taiwanesis

Hinokitiol is a tropolone type natural compound isolated from the wood of Chymacyparis taiwanesis. The compound has been utilized as a natural antimicrobial agent in hair tonics, toothpastes, cosmetics and food supplements. Hinokitiol was evaluated on five different arachidonic acid metabolic pathways for the mechanism of action of anti-inflammatory effects. It has been found to be a potent inhibitor with IC50 values of 0.1 pM against platelet-type 12-LOX and 50 pM against leukocyte-type 12-LOX. It also inhibited soybean 5-LOX enzyme (IC50 = 17 pM). However, hinokitiol had almost no effects on COX-1 and COX-2 enzymes. Similar inhibition profiles were also observed on synthetic tropolone derivatives [168]. [Pg.698]
