Elafibranor (GFT505) is an agonist of the peroxisome proliferator-activated receptor-α and peroxisome proliferator-activated receptor-δ. GFT505 has an active metabolite, GFT1007, and both have potent agonist activity for PPAR-a and to a lesser extent for PPAR-d. Elafibranor improves insulin sensitivity, glucose homeostasis, and lipid metabolism and reduces inflammation. Elafibranor (GFT505) reverses nonalcoholic steatohepatitis (NASH) to prevent fibrosis progression. With an outstanding safety and tolerance profile, elafibranor provides NASH patients with needed cardio-protective benefits. Elafibranor is currently being evaluated in the clinical Phase 3 study RESOLVE-IT. The safety profile of GFT505 from the completed clinical trials appears satisfactory with no indication of PPAR-g agonist effects such as edema or body weight gain.

m-Chlorophenylpiperazine (meta-chlorophenylpiperazine or mCPP) is a psychoactive substance, which is illegal in many countries but can be found on the black market. It induces endocrine, neurological and psychiatric effects. mCPP is a partial agonist at the 5-HT2C receptor but antagonized the 5-HT2B and 5-HT3 receptors. mCPP is also an active metabolite of the drug trazodone, which is used as an effective antidepressant drug with a broad therapeutic spectrum, including anxiolytic efficacy. It is known, that mCPP induces migraine attacks and that the decrease of food intake induced by the mCPP depends on its ability to act as a serotonin agonist is a brain.
