为了探讨印度紫檀(Pterocarpus indicus)萜类化合物的生物合成,本研究通过对合成萜类物质的MEP途径的第一个限速酶(1-脱氧-D-木酮糖-5-磷酸合酶, DXS)基因进行克隆,获得了印度紫檀DXS的全长cDNA PiDXS基因(NCBI登录号:MK959226),并对其... 为了探讨印度紫檀(Pterocarpus indicus)萜类化合物的生物合成,本研究通过对合成萜类物质的MEP途径的第一个限速酶(1-脱氧-D-木酮糖-5-磷酸合酶, DXS)基因进行克隆,获得了印度紫檀DXS的全长cDNA PiDXS基因(NCBI登录号:MK959226),并对其进行生物信息学和组织表达特异性分析。结果显示:PiDXS基因cDNA开放阅读框长2 025 bp,编码674个氨基酸,Blast比对发现,PiDXS具有一个二磷酸硫胺结合位点和一个转酮醇酶结构域;系统进化分析显示,PiDXS基因与大豆DXS和狭叶羽扇豆DXS聚为一类;组织表达特异分析结果显示PiDXS在茎、叶、树皮和根中均能表达,主要在幼嫩的组织中表达。研究结果为确定印度紫檀中DXS的基因功能以及揭示印度紫檀萜类化合物的生物合成提供了基础。 展开更多

Pterostilbene is a natural compound that can be found in various food plants such as blueberries,grapes,and peanuts.It has also been reported to be extracted from Pterocarpus indicus,a tree species native to India and Southeast Asia.Pterostilbene exhibits various pharmacological activities such as antioxidants,anti-proliferation,anti-microbial,and anti-inflammatory activities with favorable pharmacokinetic properties,such as high oral bioavailability and longer half-life.The anti-inflammatory effect of pterostilbene has been reported to contribute to its therapeutic effects in many chronic inflammatory diseases.Besides,pterostilbene has anti-cancer activity on various types of cancers due to its ability to induce cell cycle arrest and apoptosis.Hence,in this review,we discuss the anti-inflammatory and anti-cancer activities of pterostilbene in preclinical studies. 展开更多
