Van Rijn lab (PI - Richard M. van Rijn PhD)
Purdue University, College of Pharmacy, Department of Medicinal Chemistry and Molecular Pharmacology
The mission of the Van Rijn lab is to uncover new strategies to treat psychiatric and neurological disorders. We specifically investigate the heavily co-morbid triad of drug use disorders, chronic pain disorders and mood disorders. Our primary target, the delta opioid receptor, is involved in the neuropharmacology of all three disorders and thus offers an exciting novel approach to treat these disorders. The Van Rijn lab covers all aspects of preclinical drug development including drug synthesis, drug screening, pharmacological characterization both in vitro and in vivo. We also perform mechanistic studies to improve our understanding of the etiology of these disorders.

April 8th, 2018 - Congratulations to Kendall Mores for being a top rank pharmacy student worthy of induction into the Rho Chi society. The Van Rijn lab is fortunate to have already witnessed Kendall's intelligence and hard work over the last 2+ years. Outstanding accomplishment Kendall!
March 29th, 2018 - Grace Mulia, a 3rd year BSPS student has received a Dean's summer fellowship to work in the Van Rijn lab in the summer investigating ERK activation in several brain regions in male and female mice following a range of stimuli. Congratulations Grace!
March 23rd, 2018 - Dr. van Rijn was one of the invited regional speakers for the Greater Indiana Society for Neuroscience annual meeting, with a presentation entitled "The yellow brick road map to developing new alcohol use disorder treatments".
March 18th, 2018 - Congratulations to Meridith Robins and co-authors for the acceptance of the latest Van Rijn Lab manuscript in Frontiers in Psychiatry describing her findings for a role for Gi-protein activity in the dorsal striatum in reducing voluntary alcohol intake in mice. Meridith used pharmacological and pharmacogenetic (DREADD) approaches to find that activation of Gi-coupled delta opioid receptors and muscarinic M4 receptors in the dorsal striatum causes mice to drink less alcohol.
March 12th, 2018 - Congratulations to Mee Jung Ko for receiving a IBANGS Young Investigator Travel Award to attend the Genes, Brain and Behavior meeting in Rochester, Minnesota.
March 10th, 2018 - The Van Rijn lab received a 2-year $100,000 R03 grant from the National Institute for Drug Abuse to "develop G-protein biased delta opioid receptor agonist with analgesic potency". Thanks for the support.
March 6th, 2018 - Dr. van Rijn was invited to the Department of Pharmacology and Toxicology by Dr. Patrick Sheets at Indiana University School of Medicine to give a seminar entitled "Self administration of kratom to treat alcohol addiction - Why it may work"
March 5th, 2018 - Meridith Robins successfully defended her PhD Thesis "Behavioral pharmacology of alcohol and legal pscyhostimulants". Congratulations Dr. Robins!!
March 1st, 2018 - Congratulations to Meridith and co-authors for the latest publication by the Van Rijn lab in Frontiers in Behavioral Neuroscience. In the paper Meridith characterized the role of beta-arrestin 1 in several neurological behaviors using genetic knockout animal models. Merditih's data suggests that beta-arrestin 1 may have a protective role again alcohol use in females.
