Elucidating Structure, Function, And Small Molecular Interactions Of Human Immunodeficiency Virus And Chikungunya Virus, Kristin Nicole Slater

Wayne State University Theses

Abstract HIV-1:

Human immunodeficiency virus-1 (HIV-1) is a widespread, incurable retrovirus known to cause

immunodeficiency and a shortened life span. Despite successful treatment methods, HIV-1

frequently mutates, resulting in antiviral resistance. Many therapies target the HIV-1 protease

(PR), which is responsible for cleaving the viral polyprotein essential for its life cycle. HIV-1 PR

often evades treatment by way of mutations and less commonly through residue insertions. We

have identified a clinical isolate with a five residue insertion between residues 28 and 29.

Through molecular dynamics simulations we analyzed the protease protein structure and

determined that the residue insertion created a …

Biochemical, Structural, And Drug Design Studies Of Multi-Drug Resistant Hiv-1 Therapeutic Targets, Tamaria Grace Dewdney

Wayne State University Dissertations

Protein point mutations acquired as a mechanism of survival against therapeutics cause structural changes that effect protein function and inhibitor binding. This work investigates the structural mechanisms that lead to multi-drug resistance to HIV-1 protease and integrase inhibitors.

Proper proteolytic processing of the HIV-1 Gag/Pol polyprotein is required for HIV infection and viral replication. This feature has made HIV-1 protease an attractive target for antiretroviral drug design for the treatment of HIV-1 infected patients, thus the development of drug resistance has arisen as a major therapeutic and drug design challenge. To understand the molecular mechanisms leading to drug resistance we …
