Likely a misspelling of Rottlerin, a natural polyphenol compound isolated from the fruit of Mallotus philippinensis. Rottlerin is widely used in biological research as a selective inhibitor of protein kinase C delta (PKCδ). It plays a key role in studies on cell cycle regulation and programmed cell death (apoptosis), particularly in cancer research. By inhibiting survival proteins in cancer cells, it increases their sensitivity to destruction, aiding the development of cancer therapies.

Additionally, Rottlerin serves as a tool for investigating molecules involved in inflammation and neurodegenerative diseases, such as Alzheimer's disease, helping researchers gain deeper insights into disease mechanisms. It remains primarily a laboratory research reagent and is not yet widely used in clinical settings.
