摘要
以黄酮类化合物生物合成过程中的两个关键酶: 4-香豆酰辅酶A连接酶(4-coumarate coenzyme A ligase, 4CL)和查尔酮合成酶(chalcone synthase, CHS)为工具酶, 探讨酶催化组合合成在合成“非天然的天然产物”群(库)中的应用. 结果发现在4CL和CHS的共同作用下, 仅利用8个简单的有机酸就可以产生包括8个黄酮类似物、16个4-羟基-δ-内酯和1个苄基丙酮共计25个“非天然的天然产物”群, 为构建结构多样的小分子化合物群(库)提供方法学参考.
Abstract：
4-Coumarate coenzyme A ligase (4CL) and chalcone synthase (CHS), the two pivotal enzymes involved in the biosynthesis of flavonoids were applied to combinatorially synthesize varied unnatural natural products. As result, 25 unnatural natural products including eight flavonoid analogues, 16 4-hydroxy-δ-lactones and one benzalacetone were synthesized by 4CL and CHS. The synthetic methodology would be useful for the construction of library of structurally diverse of small molecules.
