CAS 133343-34-7: Lactacystin
Description:Lactacystin is a naturally occurring compound that is primarily known for its role as a proteasome inhibitor. It is derived from the bacterium *Streptomyces* and has garnered interest in the field of biochemistry and pharmacology due to its ability to selectively inhibit the proteasome, a cellular complex responsible for degrading ubiquitinated proteins. This inhibition can lead to the accumulation of regulatory proteins, thereby affecting various cellular processes, including cell cycle regulation and apoptosis. Lactacystin is often utilized in research to study the proteasome's role in cellular functions and its implications in diseases such as cancer and neurodegenerative disorders. The compound is characterized by its specific structure, which includes a lactone ring, contributing to its biological activity. While it has potential therapeutic applications, the use of lactacystin in clinical settings is limited due to its toxicity and the need for further research to understand its effects and mechanisms fully.
