Jenny Wilkerson Laboratory
About Us
Our work centers around the principles of behavioral pharmacology to answer pressing drug discovery and novel compound development questions.
Aberrant inflammation is a driving factor in many disease states including pathological pain, cancer, neurodegenerative disease, mood disorders, and drug abuse/dependence. The work done in our laboratory investigates novel compound pharmacology and therapeutic implications. We specifically focus on compounds to treat inflammation-driven diseases and diseases associated with inflammation, such as pathological pain, cancer, neurodegenerative disease, mood disorders, and drug abuse/ dependence.
Many natural products such as Cannabis sativa, Mitragyna speciosa (kratom), and the numerous compounds contained in these and other natural products have either known or speculated medicinal use. Indeed, nature has provided humankind a proverbial medicine chest of potential therapeutics. A number of natural products may be useful to modulate the immune system and are waiting to be developed as therapeutics. Another major focus of our laboratory is natural product therapeutic development and pharmacological investigation, as well as abuse liability and untoward side effect examination.

- Project #: DA047855-A1
Funding Agency: NIH/National Institute on Drug Abuse
Kratom alkaloids: in vitro and in vivo pharmacological mechanisms
04/01/2019 – 03/31/2024
Role: Co-Investigator (MPI: Dr. Chris McCurdy, PI: Lance McMahon)
Total Costs: $3,626,856
Grant detail: The major goals of this project are to determine the in vitro and in vivo pharmacological interactions among kratom alkaloids to include ADME and behavioral/physiological effects (drug discrimination, self-administration). - Project #: UH3DA048353
Funding Agency: NIH/National Institute on Drug Abuse
Opioid use disorders: UF Pharmacy medications discovery and development
12/15/2020 – 11/30/2023
Role: Co-Investigator (MPI: Dr. Chris McCurdy, PI: Lance McMahon)
Total Costs: $4,754,180
Grant detail: The major goals of this project are to initiate a drug discovery and development effort aimed at kratom alkaloid derivatives as new medications for pain and opioid dependence pharmacotherapy. New chemical entities will be derived from a mitragynine scaffold, and in vitro and in vivo pharmacological mechanisms will be explored, to include binding, efficacy, stability, ADME, and behavioral/physiological effects (drug discrimination, self-administration, respiratory depression, and dependence).
