O-Methylsterigmatocystin [17878-69-2]

O-Methylsterigmatocystin is a xanthone isolated from several species of Aspergillus and Chaetomium. O-Methysterigmatocystin is structurally related to the aflatoxins and while the available data has led it to be considered mutagenic, teratogenic and carcinogenic, it is less widespread and potent than the aflatoxins. Research on this metabolite has largely focused on its genetic and phenotypic relationship to aflatoxins.

Source: Chaetomium sp.

Apperance: Pale yellow solid

Solubility: Soluble in DMF or DMSO. Sparingly soluble in methanol and ethanol with only limited water solubility.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
