thiaplidiaquinones A and B and their respective non-natural dioxothiazine regioisomers have been shown to inhibit mammalian and protozoal farnesyltransferase (FTase) with the regioisomers exhibiting activity in the nanomolar range. In order to explore the structure-activity relationship (SAR) of this class of marine natural products, analogues of thiaplidiaquinones A and B and their regioisomers were
海洋类萜,类噻二醌A和B以及它们各自的非天然二氧噻吩嗪区域异构体已显示出抑制哺乳动物和原生动物的法呢基转移酶(FTase),其区域异构体在纳摩尔范围内具有活性。为了探索此类海洋天然产物的结构-活性关系(SAR),合成了噻二苯醌A和B及其区域异构体的类似物,其侧链中存在异戊二烯单元的数目发生变化,从而得到异戊二烯基和法呢基类似物。发现先前报道的香叶基系列化合物是最有效的FTase抑制剂,紧随其后的是新的法呢基系列。异戊二烯系列显示出最有效的抗疟原虫活性,但该系列也具有最强的细胞毒性。全面的,14也表现出低细胞毒性,将其鉴定为值得进一步探索的支架。
