Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/17305568 http://hktmc.com.cn/ChineseMedia/Magazine/Medicine/ajdmpk/AJDMPK-2010-4/AJPP%202010-4%20_287-299_%20ML3000.pdf

Licofelone (ML 3000) is a pyrrolizine derivative originally discovered by Merckle GmbH and developed by EuroAllaince with a unique pharmacological profile, which comprises optimal gastrointestinal tolerability and high analgesic and anti-inflammatory activity. These effects are due to balanced and selective inhibition of both cyclo-oxygenase and 5-lipoxygenase. Inhibition of 5-lipoxygenase may reduce the gastrointestinal toxicity associated with other non steroidal anti-inflammatory drugs, which only inhibit cyclooxygenase. Licofelone also has antipyretic and antiaggregatory properties. Clinical and preclinical trials were also undertaken for osteoarthritis, rheumatoid arthritis, asthma, pain and inflammation. However, development for these indications appear to have been discontinued.

CNS Activity

Curator's Comment: Almost no penetration of the blood-brain barrier was noted in animal study. No human data available.

Sample Use Guides

In a double-blind study, licofelone significantly improved the WOMAC (Western Ontario and McMaster Universities) osteoarthritis index and also pain, stiffness and disability relative to placebo in osteoarthritis patients when orally administered twice-daily at doses of 200mg and 400mg. A lower dose (100mg) was not sufficiently effective
Route of Administration: Oral
Using a human whole blood assay it was shown that 0.3-30 ug/ml licofelone (ML 3000) concentration-dependently inhibited the synthesis of PGE2 (IC50=3.9 uM) and 1-10 uM inhibited the synthesis of LTB4 in a concentration related manner (IC50=3.6 uM)
