Chemically modified drug shows promise for HIV treatment, elimination

Research Interests

My major focus is to understand the drug-drug interactions and signaling pathways by which drugs work in the context of HIV therapeutics. Thirty years after the discovery that HIV is the causative agent of AIDS there is still the problem of drug adherence, drug dosing and appearance of drug resistant strains and unfruitful targeting of drugs to the latent reservoirs in the patients. The goal of the laboratory is to better design long-acting formulations of existing antiretroviral drugs and also to develop new formulations, which can improve patients’ health.

On-going projects

We are currently working on developing a testing pharmacodynamic (PD) platform for the development of antiretroviral and adjunctive therapies for peripheral HIV-1 and for its related associated neurocognitive disorders. Also part of the team in the development and subsequent testing of novel ligand decorated antiretroviral formulations developed by our medicinal and polymer chemistry program for drug to drug interactions, for systemic toxicities, for testing reductions in residual viral load, for interrelationships between tissue histology (including lymphocyte and monocyte distribution) and quantitative proviral DNA and RNA measurements by sensitive PCR tests and by immunohistochemical p24 staining, assess the interrelationships between antiretroviral responses and metabolic profiling.

Another major project involves, the development of new drug formulations [long-acting antiretroviral +URMC-099 (MLK3-inhibitor)], which can increase the storage of drug formulations in specific endolysosomal compartments for several weeks, which can subsequently target and remove new infections in the lymphoid and peripheral organs. The mechanism of action of the above drug formulation is underway.
