HPOB is a selective inhibitor of the enzyme HDAC6, primarily utilized in research settings to study its effects on specific biological pathways, particularly those involved in cellular signaling and gene regulation. It modulates protein interactions, including acetylation processes that influence protein misfolding and aggregation. Researchers are exploring its application in understanding diseases related to these mechanisms, such as neurodegenerative disorders and cancer. Additionally, HPOB is being investigated for its role in enhancing the efficacy of certain therapeutic agents by improving their bioavailability or targeting capabilities. Its use in laboratory experiments helps advance knowledge in molecular biology and drug development.
