    在二酮化合物手性结构单元的化学合成中使用模块化聚酮化合物合酶酮还原酶作为生物催化剂。
    摘要:
    手性构件是天然产物和药物合成中的有价值的中间体。已开发出一种可扩展的手性二酮化学反应路线,包括一般合成α-取代的β-酮酰基N-乙酰半胱胺硫酯,然后进行生物催化循环,其中葡萄糖驱动的NADPH再生系统驱动由分离的模块化聚酮合酶催化的还原反应(PKS)酮还原酶(KRs)。为了鉴定起活性,立体定向生物催化剂作用的KR,将11个分离的KR与5个二酮化合物一起孵育,并通过手性色谱法分析其产物。天然还原小的聚酮化合物中间体的KR对双酮化合物面板最为活跃,且立体定向性最高。扩大了几种生物催化反应的规模,以生产超过100毫克的产品。

    公开号:US20030092140A1
    公开(公告)日:2003-05-15
    Facile methods for preparing diketide and triketide thioesters are disclosed. The resulting thioesters may be used as intermediates in the synthesis of desired polyketides, and may contain functional groups which ultimately reside in side chains on the resulting polyketide and thus can be used further to manipulate the polyketide so as form derivatives. The polyketides produced may also be tailored by glycosylation, hydroxylation and the like. New polyketides and their derivatives and tailored forms are thereby produced.
