Istota wynalazku polega na tym, że do podłoża odpowiedniego dla grzybów strzępkowych wprowadza się szczep Pennicilium thomi AM91. Po upływie, co najmniej 48 godzin do hodowli wprowadza się substrat, którym jest 5,7-dihydroksy-8-metoksyflawon (wogonina) o wzorze 1, rozpuszczony w rozpuszczalniku organicznym mieszającym się z wodą. Transformację prowadzi się w temperaturze od 15 do 30 stopni Celsjusza, przy ciągłym wstrząsaniu, co najmniej 2 dni. Kolejno produkt z hodowli ekstrahuje się rozpuszczalnikiem organicznym niemieszającym się z wodą i oczyszcza chromatograficznie.The essence of the invention is that the Pennicilium thomi AM91 strain is introduced into a medium suitable for filamentous fungi. After at least 48 hours, the substrate is introduced into the culture, which is 5,7-dihydroxy-8-methoxyflavone (wogonin) of formula 1, dissolved in an organic solvent miscible with water. The transformation is carried out at a temperature of 15 to 30 degrees Celsius, with constant shaking, for at least 2 days. Next, the product from the culture is extracted with an organic solvent immiscible with water and purified by chromatography.
W wyniku regioselektywnej hydroksylacji pierścienia aromatycznego otrzymuje się 5,7,4'-trihydroksy-8-metoksyflawon (4’-hydroksywogoninę) o wzorze 2, a reakcję prowadzi się w wodnej kulturze szczepu Pennicilium thomi AM91.As a result of regioselective hydroxylation of the aromatic ring, 5,7,4'-trihydroxy-8-methoxyflavone (4'-hydroxywogonine) of formula 2 is obtained, and the reaction is carried out in an aqueous culture of the Pennicilium thomi AM91 strain.
Korzystnie jest, gdy rozpuszczalnikiem mieszającym się z wodą jest dimetylosulfotlenek i/lub metanol, i/lub aceton.Preferably, the water-miscible solvent is dimethyl sulfoxide and/or methanol and/or acetone.
Korzystnie także jest, gdy proces prowadzi się w temperaturze 20-25 stopni Celsjusza.It is also preferable if the process is carried out at a temperature of 20-25 degrees Celsius.
Korzystnie jest również, gdy rozpuszczalnikiem niemieszającym się z wodą jest octan etylu albo eter dietylowy.It is also preferable if the water-immiscible solvent is ethyl acetate or diethyl ether.
Zasadniczą zaletą wynalazku jest otrzymanie 5,7,4'-trihydroksy-8-metoksyflawonu (4’-hydroksywogoniny) o wzorze 2, w temperaturze pokojowej i przy pH naturalnym dla szczepu.The main advantage of the invention is the preparation of 5,7,4'-trihydroxy-8-methoxyflavone (4'-hydroxywogonine) of formula 2, at room temperature and at a pH natural for the strain.
Wynalazek jest bliżej objaśniony na przykładzie wykonania.The invention is explained in more detail using an example embodiment.
Przykład. Do kolby Erlenmajera o pojemności 300 cm3, w której znajduje się 100 cm3 sterylnej pożywki zawierającej 1 g aminobaku i 3 g glukozy, wprowadza się szczep Pennicilium thomi AM91. Po 72 godzinach jego wzrostu dodaje się 30 mg 5,7-dihydroksy-8-metoksyflawon (wogonina) o wzorze 1, rozpuszczonego w 1 cm3 dimetylosulfotlenku (DMSO). Transformację prowadzi się w 25 stopniach Celsjusza przy ciągłym wstrząsaniu przez 8 dni. Następnie mieszaninę poreakcyjną ekstrahuje się trzykrotnie octanem etylu, osusza bezwodnym siarczanem magnezu i odparowuje rozpuszczalnik. Otrzymany ekstrakt oczyszcza się chromatograficznie, używając jako eluentu mieszaniny chloroform i metanol 15:1.Example. The Pennicilium thomi AM91 strain is introduced into a 300 cm3 Erlenmajer flask containing 100 cm3 of sterile medium containing 1 g of aminobac and 3 g of glucose. After 72 hours of its growth, 30 mg of 5,7-dihydroxy-8-methoxyflavone (wogonin) of formula 1, dissolved in 1 cm 3 of dimethyl sulfoxide (DMSO), are added. The transformation is carried out at 25 degrees Celsius with constant shaking for 8 days. The reaction mixture is then extracted three times with ethyl acetate, dried over anhydrous magnesium sulfate and the solvent is evaporated three times. The obtained extract is purified by chromatography using a 15:1 mixture of chloroform and methanol as the eluent.
Na tej drodze otrzymuje się 5,7,4'-trihydroksy-8-metoksyflawon (4’-hydroksywogoninę) z wydajnością izolowaną 17%.In this way, 5,7,4'-trihydroxy-8-methoxyflavone (4'-hydroxywogonine) is obtained with an isolated yield of 17%.
