摘　　要：选择法尼基转移酶(FTase)和香叶基香叶基转移酶(GGTase-I)作为靶标,利用Autodock系列软件,将Artemisian C和Artemisian D两个倍半萜内酯二聚体与FTase和GGTase-I两个蛋白分别进行了分子对接,并分析了各自的作用模式。结果:Artemisian C与Artemisian D与FTase的结合能分别为-44.379和-47.0166 kJ/mol,Artemisian C与Artemisian D与GGTase-I的结合能分别为-33.4066 kJ/mol和-39.2209k J/mol。两个化合物能够以氢键和疏水作用与两种蛋白相结合。结论:ArtemisianC与Artemisian D能够在一定程度上抑制FTase和GGTase-I活性,是这两个靶标的双重抑制剂。两种分子能够以多药多靶的形式协同发挥抗肿瘤作用。Farnesyl transferase(FTase)and geranylgeranyl transferase(GGTase-I)were selected as targets,using Autodock series software,Artemisian C and Artemisian D sesquiterpene lactone dimers were docked with FTase and GGTase-I proteins,respectively,and their respective action modes were analyzed.The results showed that,the binding energies of Artemisian C and Artemisian D with FTase were-44.379 kJ/mol and-47.0166 kJ/mol,respectively.The binding energies of Artemisian C and Artemisian D with GGTase-I were-33.4066 kJ/mol and-39.2209 kJ/mol,respectively.The two compounds could bind to the two proteins by hydrogen bonding and hydrophobic interaction.Artemisian C and Artemisian D can inhibit the activity of FTase and GGTase-I to a certain extent,and are dual inhibitors of these two targets.The two molecules can synergistically exert anti-tumor effects in the form of multi-drug and multi-target.
