5-Lipoxygenase inhibitors: a review of recent developments and patents.
BACKGROUND
Leukotrienes (LTs) are pivotal lipid mediators of inflammation and allergy and results from recent studies also suggest roles of LTs in cardiovascular diseases, cancer and osteoporosis. 5-Lipoxygenase (5-LO) catalyzes the first step in the biosynthesis of LTs from arachidonic acid, and based on the multiple potent pathophysiological actions of LTs, the pharmacological intervention with 5-LO is a challenge in the development of therapeutics.


METHODS
We first summarize the biochemical regulation of 5-LO and the general pharmacological concepts in 5-LO inhibition by currently available compounds, and subsequently we report recent developments deduced from recent scientific publications and patents.


RESULTS
A comprehensive overview about the different molecular pharmacological strategies to inhibit 5-LO and the most successful previous 5-LO inhibitors. The review also gives insights into novel concepts, for example, dual prostaglandin/LT synthesis inhibition and reveals novel compounds patented or developed within the past 5 years.


CONCLUSIONS
Despite the increasing therapeutic indications of anti-LT therapy, the progress in the development of novel 5-LO inhibitors is moderate. However, novel molecular concepts in the intervention with LT biosynthesis seem promising.
