  Microbial transformations of betulinic and betulonic acids

  摘要：

  Enzymatic transformation of betulinic acid by growing cells of microorganisms provided several hydroxylated and oxidized products. Bacillus megaterium SC16644 gave 7 beta,15 alpha-dihydroxybetulinic acid, 7 beta,15 alpha-dihydroxybetulonic acid, and a new compound 7 beta,15 alpha,23-trihydroxybetulinic acid [3 beta,7 beta,15 alpha,23-tetrahydroxy-lup-20(29)en-28-oic acid]. Another strain of B. megaterium SC6394 produced 30-oxobetulonic acid, and a mixture of 30-hydroxybetulonic acid and a new compound 7 beta-hydroxy-30-oxobetulonic acid [7 beta-hydroxy-3,30-dioxo-lup-20(29)en-28-oic acid]. Three products were obtained from the biotransformation of betulinic acid by Streptomyces frag-ilis SC16401: 7 beta-hydroxybetulonic acid, and two new compounds 2 alpha,7 beta-dihydroxybetulinic acid [2 alpha,3 beta,7 beta-trihydroxy-lup-20(29)en-28-oic acid] and 2-oxo-7 beta-hydroxy-betulinic acid [2-oxo-3 beta,7 beta-dihydroxy-lup-20(29)en-28-oic acid]. Cunninghamella elegans SC16025 gave 25-hydroxybetulinic acid from betulinic acid. Oxidation of betulinic acid by Aspergillus terreus SC16513 led to two A-ring fission products: 4-hydroxy-3,4-seco-lup-20(29)-en-3,2b-dioic acid and 3,4-seco-lup-20(29), 4(23)-dien-3,28-dioic acid. B. megaterium SC16644 catalyzed transformation of betulonic acid provided 7 beta-hydroxybetulonic acid, 7 beta,15 alpha-dihydroxybetulonic acid, and a new compound 7 beta,15 alpha,30-trihydroxybetulonic acid [3-oxo-7 beta,15 alpha,30-trihydroxy-lup-20(29)en-28-oic acid].

  Microbial transformation of betulin (1), a lupane-type triterpene obtained from the bark: extract of white birch (Betula platyphylla Sukatshev var. japonica), and its chemical oxidation product, betulonic acid (2), by the fungus Chaetomium, longirostre yielded 4,28-dihydroxy-3,4-seco-lup-20(29)-en-3-oic acid (3) and 4-hydroxy-3,4-seco-lup-20(29)-ene-3,28-dioic add (4) from 1, and 4,7beta,17-trihydroxy-3,4-seco-28-norlup-20(29)-en-3-oic acid (5) and 7beta,15alpha-dihydoxy-3-oxolup-20(29)-en-28-oic acid (6) from 2. The four metabolites, 3-6, along with 1 and 2, were evaluated for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) in Raji cells as a primary screening test for inhibitors of tumor promotion. All of the triterpenes tested showed potent inhibitory effects, with the four metabolites 3-6 exhibiting the more potent effects.
