The present invention relates to the production of a product compound having a structure according to Formulae IA and/or IB:
1
wherein
n is 0 or 1;
R
1
is hydrogen or hydroxy;
R
2
is hydrogen;
or, when n is 0, R
1
and R
2
taken together form a second bond between the carbon atoms bearing R
1
and R
2
, provided that when n is 1, R
1
and R
2
are each hydrogen;
R
3
is —COOH or —COOR
4
;
R
4
is an alkyl or aryl moiety;
A, B, and D are the substituents of their rings, each of which may be different or the same, and are selected from the group consisting of hydrogen, halogens, alkyl, hydroxy, and alkoxy.
This process involves incubating a starting compound having a structure according to Formulae IIA and/or IIB:
2
wherein R
3
is —CH
3
and R
1
, R
2
, A, B, and D are defined above. in the presence of a microorganism under conditions effective to produce the product compound. The microorganism can be from the genus Streptomyces, Stemphylium, Gliocladium, Bacillus, Botrytis, Cyathus, Rhizopus, Pycniodosphora, Psuedomonas, Helicostylum, Aspergillus, Mucor, Gelasinospora, Rhodotorula, Candida, Mycobacterium, or Pennicillium. Alternatively, the microorganism can be
Cunninghamella bainieri.
本发明涉及生产一个化合物,其结构符合公式IA和/或IB,其中n为0或1;R1为氢或羟基;R2为氢;或者,当n为0时,R1和R2共同形成连接R1和R2的碳原子之间的第二个键,但当n为1时,R1和R2均为氢;R3为—COOH或—COOR4;R4为烷基或芳基基团;A、B和D为它们的环的取代基,每个取代基可以不同也可以相同,且选择自氢、卤素、烷基、羟基和烷氧基的群。该过程涉及在微
生物的存在下孵育一个具有符合公式IIA和/或IIB的起始化合物,其中R3为—
CH3,R1、R2、A、B和D如上所定义,以有效的条件产生产品化合物。该微
生物可以来自属于链霉菌、茎腐菌、灰葡萄孢、芽孢杆菌、灰霉菌、杯状孢、根霉菌、小球孢菌、假单胞菌、螺旋菌属、曲霉属、毛霉属、肉座菌属、红酵母、念珠菌、结核分枝杆菌或青霉菌的微
生物。或者,该微
生物可以是拟青霉属真菌。
