CPTH2 hydrochloride is a selective inhibitor of histone acetyltransferases (HATs), primarily utilized in research settings to study its potential as a therapeutic agent. It modulates epigenetic processes by inhibiting HATs, which play a key role in gene expression regulation. It has shown promise in modulating specific biological pathways, particularly those involved in cell cycle regulation and apoptosis. Researchers are investigating its efficacy in targeting cancer cells, as it may inhibit proliferation and induce cell death in malignant tissues through epigenetic changes. Additionally, it is being explored for its role in neurodegenerative diseases, where it could potentially mitigate neuronal damage. Its application in experimental models helps in understanding its mechanism of action and assessing its safety profile for future clinical use.
