Research

Research Summary/Interests

Current research in the Pharmacokinetics (PK) lab has focused on profiling the in vitro ADME (absorption, distribution, metabolism, and excretion) and in vivo PK properties of lead compounds from medicinal chemistry efforts. Our work can provide a basis for chemists to select and optimize the leads that have desirable “drug-like” properties, necessary for drug candidate selection before the preclinical and clinical development. A wide range of ADME/PK assays and techniques are employed in our research. These include:

  • Microsomal stability, S9 stability, Plasma stability, Aqueous stability
  • Cytochrome P450 inhibition, reaction phenotyping
  • Plasma protein binding, brain tissue binding, blood to plasma ratio
  • Solubility
  • Caco-2, MDCK and PAMPA permeability
  • Oral bioavailability and tissue distribution in rodent
  • PK modeling and simulation using Phoenix WinNonlin®
  • LC/MS/MS bioanalysis

Our other research focus is to improve drug response in combination chemotherapy and combat cancer drug resistance. Particularly, we devote a large portion of our research to identifying novel compounds that impact cellular uptake or inhibit drug efflux - the most common mechanism underlying acquired drug resistance in cancer, pinpointing the transporters or targets involved in these processes, and evaluating regimens to produce desirable anti-cancer responses.
