Abstract
Wynalazek dotyczy sposobu wytwarzania nowego związku chemicznego (Z)-2",2"-dimetylo-2H-pirano[5",6":6,7]-4'-hydroksy-4 -metoksyauronu, o wzorze 2, na drodze transformacji mikrobiologicznej, przy użyciu systemu enzymatycznego grzybów z gatunku Melogramma camphylosporum. Jako substrat stosuje się (Z)-6,4'-dihydroksy-4-metoksy-7-prenyloauron. Związek o wzorze 2 będący przedmiotem wynalazku, jest biologicznie czynny i może mieć zastosowanie w przemyśle spożywczym i farmaceutycznym.The invention relates to a process for the preparation of the new chemical compound (Z) -2 ", 2" -dimethyl-2H-pyran [5 ", 6": 6.7] -4'-hydroxy-4-methoxyaurone, of formula 2, by transformation microbiological, using the enzyme system of fungi of the species Melogramma camphylosporum. The substrate used is (Z) -6,4'-dihydroxy-4-methoxy-7-prenylauron. The compound of formula II according to the invention is biologically active and can be used in the food and pharmaceutical industries.
