Inhibition of growth and patulin synthesis in Penicillium.

Patulin is toxic to many biological systems, including bacteria, mammalian cell cultures, higher plants, and animals, but its role in causing animal and human disease is unclear. Patulin has a lactone structure and is carcinogenic when injected intradermally into mice (Figure 4).Patulin is produced by numerous Penicillium and Aspergillus species and Byssochlamys nivea.Patulin, a mycotoxin produced mainly by Aspergillus and Penicillium, is commonly found in moldy fruits and their derivative products (45), and it has been suggested that the induction of oxidative.We have examined a number of complementary synthetic approaches to patulin, and in this Letter we 2875 2876 outline a particularly concise synthesis of this intriguing molecule, starting from the readily available sugar, arabinose (5) (Scheme). 12 Thus, arabinose (5) was first converted into the crystalline benzyl 3,4-O-isopropylidene arabinoside (6), m.p. 57-57.5 (Et20-petrol)13 following.


Potassium sorbate and sodium propionate brought about a marked inhibition in the growth of Penicillium expansum and a proportionally greater inhibition in the synthesis of patulin by the mold. At inhibitor concentrations used commercially in bakery products, propionate inhibited growth less efficiently than sorbate did but was a more effective inhibitor of patulin synthesis.Synthesis essays are used in different papers.
