Abstract

Enhanced production of (10-deacetyl) baccatin III and related taxanes was observed in suspension cultures of Taxus baccata Pendula. six % of initial glucose and sucrose concentration increased 10-deacetyl baccatin III production 3.5 and 2.5 times, respectively. Methyl jasmonate, as an elicitor, increased taxane production. Time course changes of taxane production after methyl jasmonate addition showed that baccatin II and 10-deacetyl baccatin III were detected first and paclitaxel, 10-deacetyl taxol and cephalomanine were produced in sequence. Feeding experiments with $500{\mu}M$ of benzoic acid increased 10-deacetyl baccatin III production 10 times. Baccatin III production was also increased 8 times by feeding of $500{\mu}M$ of lysine as a precursor.

유럽주목(Taxus baccata Pendula)현탁 세포 배양에서(10-deacetyl) baccatin III 생산을 증진시키는 연구를 하였다. 높은 초기 당 농도가(10-deacetyl) baccain III 생산을 증진시키는 연구를 하였다. 6% 의 초기 포도당과 자당의 경우 1O-deacetyl baccatin III 생산을 각각 3.배와 2.5배씩 증가시켰다. Baccain III도 초기 포도당 8%에서,초기 자당 6%에서 최대값을 보였다. 일리시터로서 methyl jasmonate는(10-deacetyl) baccatin III 의 생성은 $50{\mu}$M에서 최대치를 보였는데 이는 대조구에 비하여 4.5배 증가한 값이었다.Baccatin III 의 경우 methyl jasmonate $100{\mu}$M에서 생성된 Baccatin III 최대치는 대조구에 비하여 7.배 증가한 값이었다. Methyl jasmonate elicitation 에 의한(1O-deacetyl) baccatin III.과 각 taxane의 시간별 생성 경향을 보면 baccatin III와 10-deacetyl baccatin III는 투여 후 1일 까지 생성이 증가하다 그 후부터 감소하였고, paclitaxel, 10-deacetyl taxol 및 cephalomanine 의 생성이 이어졌다. (10-deacetyI) baccatin III의 생합성을 증가시키기 위하여 전구 물질을 투여하였다. Benzoic acid를 $500{\mu}M$로 투여 하였을 때 10-deacetyl baccatin III 및 baccatin III의 생산은 대조구의 비하여 각각 10배와 13배 증가 하였다. Lysine도 $500{\mu}M$로 투여하였을 때 baccatin III 의 생성량을 대조구 보다 8배 증가시켰다. 증가시켰다.
