Disclosed are methods, compositions, proteins, nucleic acids, cells, vectors, compounds, reagents, and systems for the preparation of kavalactones, flavokavains, and kavalactone and flavokavain biosynthetic intermediates using enzymes expressed in heterologous host cells, such as microorganisms or plants, or using in vitro enzymatic reactions. This invention also provides for the expression of the enzymes by recombinant cell lines and vectors. Furthermore, the enzymes can be components of constructs such as fusion proteins. The kavalactones produced can be utilized to treat anxiety disorder, insomnia, and other psychological and neurological disorders. The flavokavains produced can be utilized to treat various cancers including colon, bladder, and breast cancers.
本发明公开了利用在异源宿主细胞(如微生物或植物)中表达的酶或利用体外酶促反应制备卡瓦内酯、黄酮素以及卡瓦内酯和黄酮素生物合成中间体的方法、组合物、蛋白质、核酸、细胞、载体、化合物、试剂和系统。本发明还提供了通过重组细胞系和载体表达酶的方法。此外,酶还可以是融合蛋白等构建体的组成部分。生产的卡瓦内酯可用于治疗焦虑症、失眠症以及其他心理和神经疾病。生产的黄酮类化合物可用于治疗各种癌症,包括结肠癌、膀胱癌和乳腺癌。
