Abstract The HIV-1 maturation inhibitor (MI) VH3739937 (VH-937) inhibits cleavage between capsid and spacer peptide 1 and exhibits an oral half-life in humans compatible with once-weekly dosing. Here, the antiviral properties of VH-937 are described. VH-937 exhibited potent antiviral activity against all HIV-1 laboratory strains, clinical isolates, and recombinant viruses examined, with half-maximal effective concentration (EC(50)) values /= 92%. However, VH-937 was less potent against A364V in single-cycle assays (EC(50), 32.0 nM; MPI, 57%) and A364V emerged in one of four resistance selection cultures. Other substitutions were selected by VH-937, although re-engineered viruses with these sequences were non-functional in multiple-cycle assays. Measured dissociation rates from wild-type and A364V-containing VLPs help explain resistance to the A364V mutation. Overall, the in vitro antiviral activity of VH-937 supports its continued development as a treatment for HIV-1.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
  • Location: The source of the research data.
