O-methyl Sterigmatocystin (OMST) is primarily studied for its role in mycotoxin research, particularly in understanding the biosynthesis and toxicological effects of aflatoxins. It serves as an intermediate in the aflatoxin production pathway, making it valuable for investigating fungal metabolism and the mechanisms of mycotoxin formation. Researchers use OMST to explore its potential mutagenic and carcinogenic properties, contributing to studies on food safety and the development of strategies to mitigate contamination in agricultural products. Additionally, it is utilized in biochemical assays to study enzyme activities involved in mycotoxin synthesis, aiding in the development of inhibitors or detoxification methods.
