Tanvir Khaliq
Biography
After receiving his Ph.D. in medicinal chemistry, Khaliq was a postdoctoral fellow at the University of Washington and the University of Kansas, where he rose through the ranks as an associate researcher prior to moving to the University of Florida as a senior chemist in medicinal chemistry.
Khaliq has discovered novel natural products and designed and synthesized their analogs that are orally active against the drug-resistant strains of leishmaniasis and malaria. He has developed a cost-effective and reliable screening method for newborn screening of inborn errors of metabolism. These methods are being used in newborn screening laboratories across the United States as well as abroad. He has characterized preclinical pharmacokinetic properties of structurally novel and orally bioavailable macrocyclic tetrapeptides that are active at the kappa opioid receptors to facilitate their potential development as treatments for pain and drug abuse.
Khaliq teaches medicinal chemistry in the professional pharmacy and the pharmaceutical sciences graduate programs. He is a member of the American Chemical Society in the Divisions of Organic, Medicinal and Biological Chemistry and the Rho Chi Honor Society.

ĢƵ and Scholarly Work
Areas of ĢƵ
Work in Khaliq’s laboratory is primarily focused on antiparasite drug discovery and development. ĢƵ focuses on the rational design and synthesis of novel analogs of natural products as antiparasite agents for their potential development as treatments against leishmaniasis and trypanosomiasis, which have led to a devastating impact on public health in the developing world. A major emphasis is on developing cost-effective and orally active molecules that are also active against the drug-resistant strains.
One of the current projects in his laboratory is exploring the structure-activity relationships of a structurally novel and an orally active quinazoline alkaloid to optimize its antiparasite activity against the clinically relevant intracellular leishmania parasite. The compounds are studied both in vitro against the intracellular parasites and in vivo in murine visceral leishmaniasis model. Selected compounds are evaluated for their pharmacokinetic properties and against the clinically resistant strains to facilitate their potential development. The laboratory utilizes both classical medicinal chemistry and structure- and ligand-guided approaches to design novel compounds and uses efficient synthetic procedures for the rapid generation of the rationally designed molecules.
