The focus of research in the Lampe lab is understanding the role of drug metabolism and pharmacokinetics (DMPK) in drug efficacy within special population groups, with a particular emphasis on cytochrome P450 enzymes (CYP). Studies based on in vitro, structural, and computational models are used to gain more insight as to how neonates metabolize HIV drugs and the importance of CYP3A ontogeny in the liver. Research on how CYP polymorphisms in African Americans can lead to different pharmacokinetic and pharmacodynamic (PKPD) effects of certain antipsychotic drugs is also an area of active investigation in the laboratory. A third project is focused on studying the role of the ‘pathobiome’ in drug metabolism, particularly in cystic fibrosis patients. Lastly, the molecular mechanisms that underlie reproductive, developmental, and immunological toxicities in populations exposed to high levels of the man-made per- and polyfluoroalkyl substances (PFAS) is another research project area.
This research project involves functional and computational modeling of HIV drug metabolism in the neonatal liver to accurately predict drug metabolism and disposition in the neonate and developing infant. Data generated from in vitro studies using CYP3A7 recombinant enzyme, a neonatal specific CYP isoform, and neonatal human liver microsomes are being modeled to define the QSAR of CYP3A7-mediated metabolism of HIV inhibitors and to build a PBPK model for the neonatal disposition and DDI risk of these HIV drugs using the GastroPlus® software package.

PFAS, the “forever chemicals”, are associated with a wide variety of illnesses (hyperlipidemias, cancer, immunotoxicity, hepatotoxicity and developmental defects). The molecular mechanisms related to PFAS toxicities are not well understood. Via a collaboration with Dr. Rebecca McCullough, changes in oxylipin production and in inflammatory signals after PFAS exposure are being investigated as part of the hepatic response to these ubiquitous environmental contaminants.
The Covid-19 pandemic has unsettled daily life and impacted the global economy, but viruses like SARS-CoV-2 will also continue to threaten human society in the future. Mutations in the viral genome lead to new viral propagation waves and also new health restrictions. Vaccination may mitigate the total number of people infected but will not provide treatment for those already infected. Targeting the main protease of SARS-CoV-2 using a modular inhibitor approach is our proposed strategy to inhibit new viral variants and circumvent potential viral drug resistance. We are currently exploring the potential of SARS-CoV-2 protease inhibitors in collaboration with the Reigan laboratory.

By understanding the differences in DMPK between the general adult population and understudied patient groups like neonates or African Americans, we are hoping in the long term to improve drug treatment which will lead to a better quality of care for these patients. We expect that our research will contribute to new and critical knowledge on drug therapy at the developmental, genetic and disease levels.
