diacetoxy Scirpenol-13C19

diacetoxy Scirpenol-¹³C₁₉ is intended for use as an internal standard for the quantification of diacetoxy scirpenol by GC- or LC-MS. diacetoxy Scirpenol is a trichothecene mycotoxin originally isolated from F. equiseti.¹ It is toxic to pigs (LD₅₀ = 0.38 mg/kg, i.v.) and lethal to brine shrimp (LC₅₀ = 0.39 µg/ml).^2,3 diacetoxy Scirpenol (1 µg/ml) suppresses phagocytosis by, and superoxide production in, isolated mouse macrophages in an S. cerevisiae model of phagocytosis.⁴ It is toxic to barley, wheat, and sorghum seedlings (LD₅₀s = 1.26, 3.98, and 10 mg/L, respectively).⁵ It has been found as a contaminant in grasses intended to be used as animal feed.⁶
