ChemInform Abstract: Total Synthesis of Ardisiaquinone A, a Potent 5-Lipoxygenase Inhibitor, Isolated from Ardisia sieboldii, and Degree of 5-Lipoxygenase Inhibitory Activity of Its Derivatives

Autor: Yuuko Kiriyama, Yoshiyasu Fukuyama, Kuniaki Matsui, Hideyuki Iwaki, Mitsuaki Kodama, Shinji Aki, Shigeki Hosozawa

Publikováno v: ChemInform. 26

Ardisiaquinone A (1), isolated as a potent 5-lipoxygenase inhibitor from the woods of Ardisia sieboldii, has been synthesized efficiently via a cross-coupling reaction between the yne 5 and the iodide 6 derived from the common intermediate 4. Inhibit
