Antimitotic activity of lobaric acid and a new benzofuran, sakisacaulon A from Stereocaulon sasakii.
Lobaric acid (1) has been isolated from lichen, Stereocaulon sasakii together with a new benzofuran, sakisacaulon A (2). Lobaric acid (1) inhibited the polymerization of tubulin. Structure-activity relationship of lobaric acid and its derivatives on inhibitory activity of tubulin polymerization was discussed.
