Tetramic Acid Analogues Produced by Coculture of Saccharopolyspora erythraea with Fusarium pallidoroseum

Coculture of the fungus Fusarium pallidoroseum with the bacterium Saccharopolyspora erythraea was found to produce three new decalin-type tetramic acid analogues related to equisetin. The structures were determined by spectroscopic methods. The absolute configurations were established by circular dichroism spectroscopy and comparing the data with those of equisetin.

Monopyrrolic natural compounds including tetramic acid derivatives.

Imagine that you get such certain awesome experience and knowledge by only reading a book. How can? It seems to be greater when a book can be the best thing to discover. Books now will appear in printed and soft file collection. One of them is this book monopyrollic natural compounds including tetramic acid derivatives. It is so usual with the printed books. However, many people sometimes have ...

Trichosetin, a novel tetramic acid antibiotic produced in dual culture of Trichoderma harzianum and Catharanthus roseus Callus.

The dual culture of Trichoderma harzianum and Catharanthus roseus callus produced an antimicrobial compound with a remarkable activity against the Gram-positive bacteria Staphylococcus aureus and Bacillus subtilis. Structural elucidation revealed that this compound, which we have named trichosetin, is a novel tetramic acid (2,4-pyrrolidinedione) antibiotic and a homolog of the fungal metabolite...

Glionitrin B, a cancer invasion inhibitory diketopiperazine produced by microbial coculture.

A new diketopiperazine, glionitrin B (1), was produced using a microbial coculture of the fungus Aspergillus fumigatus KMC-901 and the bacterium Sphingomonas sp. KMK-001 that were isolated from acidic coal mine drainage. The structure of 1 was determined to be (3S,10aS)-dithiomethylglionitrin A. This structure was determined by the analyses of extensive NMR data and the circular dichroism spect...
