Integracin B is primarily used in research settings for its role in studying cellular integration processes, particularly in the context of viral DNA integration into host genomes. It serves as a reference compound in assays evaluating the activity of integrase enzymes, which are critical in the life cycle of retroviruses such as HIV. Due to its structural and functional properties, Integracin B is employed to assess inhibition mechanisms and to support the development of antiretroviral agents. It is also utilized in biochemical studies to probe protein-DNA interactions and to validate the efficacy of integrase inhibitors during early drug discovery phases. Its application remains confined to laboratory and pharmaceutical research, with no current use in clinical or industrial processes outside of experimental models.
