Bacteriohopanetetrol and related compounds useful for modulation of lipoxygenase activity and anti-inflammatory applications

摘要

The arachidonic acid-metabolizing hopanoid tetrahydroxybacteriohopane (THBH) was isolated from Zymomonas mobilis and was found to inhibit soybean 15-lipoxygenase, and thus lipoxin biosynthesis, with an IC50 of about 10 muM. The activities of two other arachidonic acid-metabolizing enzymes, human 5-lipoxygenase (involved in prostaglandin biosynthesis) and prostaglandin H synthase, were unaffected by THBH. Subsequent studies showed that THBH was effective as an anti-inflammatory agent in topical applications.
