Rottlerin is primarily used in research settings as a protein kinase C delta (PKCδ) inhibitor, which helps in studying cellular signaling pathways and their roles in various biological processes. It is also investigated for its potential anti-cancer properties, as it can induce apoptosis in certain cancer cells. Additionally, Rottlerin has been explored for its effects on autophagy and its ability to modulate inflammatory responses, making it a subject of interest in studies related to neurodegenerative diseases and immune regulation. Its application extends to understanding mitochondrial function and oxidative stress, contributing to insights in metabolic disorders.
