現今科技發達，藥物大多數也能夠在實驗室或藥廠裡利用化學物合成出來。790Please respect copyright.ＰＥＮＡＮＡTA6g17KQtZ

但若果藥物主要成份的結構實在是太過複雜的話，有時候利用人工合成的方法製造只會吃力不討好，不符合經濟效益。790Please respect copyright.ＰＥＮＡＮＡiTBP3h8tXR

就以治療神經肌肉問題等疾病為例的Tropane alkaloids(TAs)，主要情況下均是會從特定品種的植物裡頭提取出來;790Please respect copyright.ＰＥＮＡＮＡVFewhjKKv2

隸屬TAs類別的hyoscyamine及scopolamine可以與acetylcholine receptor結合，更有著解除俄國神經毒素Novichok的能力。790Please respect copyright.ＰＥＮＡＮＡtAT3RUIqkw

（圖2）科學家一直致力研究增強培植產生TAs植物的方法，但人口增長快速，相關藥物供不應求的問題開始湧現。790Please respect copyright.ＰＥＮＡＮＡeJS49Pb0Qw

再加上植物佔據大量空間及資源，而且生長需時，還有害蟲侵蝕植物導致產量下降各種問題需要關注，長遠來說顯然需要另一種手段製作藥物。790Please respect copyright.ＰＥＮＡＮＡQ0fZkt0gJp

（圖3）近日，有科學家發表文章（Ref1)，利用生長快、易打理的酵母(yeast)來解決這問題。790Please respect copyright.ＰＥＮＡＮＡnURuFZPYaD

他們利用CRISPR基因編輯技術，將26種來自細菌及植物的基因（其中一種更是燕麥的基因）加進酵母裡頭，強迫酵母利用葡萄糖及氨基酸轉化成為有用的TAs。790Please respect copyright.ＰＥＮＡＮＡDN74zKbieE

過程中他們更分門別類將相應的酵素安放在酵母各個位置，以及刪走一些礙事的基因，務求令到酵母一心一意為製作藥物為主。790Please respect copyright.ＰＥＮＡＮＡcWPvn3RMx4

暫時他們做到的產量為每一公升酵母能夠生產出30-80 μg TAs，有望在1-2年後提升至每升5g，踏進真實市場裡頭運作。790Please respect copyright.ＰＥＮＡＮＡcwZjIzWUhJ
