التحويل الحيوي المركب B-caryophyllene عن طريق فطر Aspergillus Niger أنتج مركب واحد رئيس المركب الناتج تم تعريفه عن طريق الطرق المطيافيه المختلفه و تم توثيقه هنا كمركب جديد تم دراسة المركب الناتج كمضاد للأكسده مقارنة ب B- caryophyllene و ascorbic acid حيث وجد أن مركب الأيض الناتج لديه تأثیر متوسط که مضاد لانكده.

الملخص الإنجليزي

Microbial transformations are organic reactions, catalyzed by microorganisms such as fungi.

They are often the key steps in the synthesis of many drug molecules, and natural products and their derivatives.

This technique has also been widely employed for the synthesis of new analogues of terpenoids.

During this work, a comparative microbial transformational study of selected terpenoid (β-caryophyllene) was carried out by various fungi to produce a new metabolite with interesting biological activities.

The transformed product was purified by using chromatographic procedures, and its structure was elucidated with the help of the spectroscopic techniques.

The transformed product was also evaluated for their biological activities, such as antioxidant and β-carotene bleaching assays.

β-Caryophyllene ((1R,4E,9S)-4,11,11-trimethyl-8-methylidenebicyclo [7.2.0] undec- 4ene, C15H24) (1), a bicyclic sesquiterpene isolated from the essential oils of the stems and the flowers of Syzgium aromaticum (cloves), and the essential oils of Cannabis sativa and Salvia rosmarinus (rosemary), has been shown to have anti-cancer, antioxidant, anti-inflammatory and anti-bacterial activities.

Microbial transformation of β-caryophyllene (44), by suspended cell-cultures of the plant pathogenic fungus Aspergillus niger, resulted in the production of one metabolite.

The metabolite was identified as (3a,11a, E)-9-methyl-4- methylene3a,4,7,10,11,11a-hexahydro-2H-furo[3,2-c] oxecine-2,6(3H)-dione (45), by different spectroscopic methods.

Compound 2 was found to be new.
