It belongs to the ontological category of sterigmatocystins in the ChEBI Ontology tree. The United Nations designated GHS hazard class pictogram is Acute Toxic;Health Hazard, and the GHS signal word is DangerThe storage condition is described as Dry, dark and at 0 - 4 C for short term (days to weeks) or -20 C for long term (months to years).. Use and application categories indicated by third-party sources: Polyketides [PK] -> Aflatoxins and related substances [PK10]. However, this does not mean our product can be used or applied in the same or a similar way.
Biosynthesis Studies and Fungal Physiology
- Sterigmatocystin serves as a precursor molecule in the biosynthetic pathway of aflatoxins, another group of potent carcinogens produced by Aspergillus species. Studying sterigmatocystin production helps researchers understand the regulation and enzymatic steps involved in aflatoxin biosynthesis. This knowledge can be used to develop strategies to control aflatoxin contamination in food and agricultural products.
Toxicology and Carcinogenesis Research
- Due to its mutagenic and DNA-damaging properties, sterigmatocystin itself is used in some toxicology studies to investigate mechanisms of carcinogenesis []. Researchers can explore how sterigmatocystin interacts with cellular processes and disrupts DNA replication, ultimately leading to cancer development [].
Development of Detection Methods
- The presence of sterigmatocystin in food products can indicate potential aflatoxin contamination. Researchers use sterigmatocystin as a standard or reference compound to develop and validate analytical methods for detecting these harmful toxins in food samples.
Important Note:
- It's crucial to emphasize that due to its hazardous nature, handling and research involving sterigmatocystin requires strict safety protocols and adherence to regulations set by governing bodies.
