Dr. David E. Nichols is Professor Emeritus of Pharmacology at Purdue University and an Adjunct Professor at the University of North Carolina at Chapel Hill. He is also Chairman of the Board and a Co-Founder of the Heffter Research Institute. In addition, he held the position of Robert C. and Charlotte P. Anderson Distinguished Chair in Pharmacology at Purdue University for almost 38 years. Dr. Nichols earned his Bachelor’s Degree in Chemistry from the University of Cincinnati in 1969 and his Ph.D. in Medicinal Chemistry from the University of Iowa in 1973. Dr. Nichols also serves on the Scientific Advisory Board for the Beckley Foundation.
In 1986, Dr. Nichols wrote a highly-cited paper published in Pharmacology Biochemistry and Behavior in which he laid out the relationship between the molecular structure of compounds and their hallucinogenic activity.1 In this paper, he proposed a new class of hallucinogens called empathogens which he later renamed entactogens.
Dr. Nichols’ current research focuses on systems and receptors in the brain that use the neurotransmitters dopamine and serotonin.2-9 In 2004, he was invited to write a review paper for Pharmacology & Therapeutics on hallucinogens which has become a cornerstone publication with over 1,000 citations by other researchers.10 In 2013, Dr. Nichols wrote an article with Dr. David Nutt of Imperial College London and Leslie King on the impact of drug laws on scientific research which was published in Nature Reviews Neuroscience.11
Dr. Nichols’s lab also has a continuing interest in the serotonin 5-HT1A, 5-HT2A, and 5-HT2C receptors as likely targets for hallucinogenic/psychedelic substances and atypical antipsychotic drugs, and the possible roles that these receptor systems may play in normal cognitive function. These projects are comprised of systematic structural modification, coupled with a pharmacological assay, with a view toward identifying structural determinants of the ligand-binding domain in these receptors.
One theme of Dr. Nichols’s research has been to identify how molecules from different chemical classes can all be accommodated within the same receptor binding site. More recently he has been studying the second messenger systems that are coupled to the 5-HT2A receptor and investigating their relative importance in the actions of hallucinogenic drugs. He has also developed a computer-based homology model of several G protein-coupled receptors and is attempting to understand the functional elements within the receptor that are key to agonist activation.
