Squalene-hopene cyclase (SHC) is a useful model enzyme for predicting molecular interactions with oxidosqualene cyclase (OSC). Structure–activity relationships were investigated for numerous coumarin-derived inhibitors of SHC, and structural simplifications are suggested. Both umbelliferone and 2,4-dihydroxyacetophenone provide convenient starting nuclei for the design of SHC inhibitors. Derivatives bearing an ω-epoxyfarnesyl moiety or just a plain alkyl chain showed an inhibitory effect on a recombinant SHC from Alicyclobacillus acidocaldarius expressed in Escherichia coli.
角鲨烯-蒎烯环化酶(SHC)是预测与氧化角鲨烯环化酶(OSC)分子相互作用的有用模型酶。我们研究了多种香豆素衍生的 SHC 抑制剂的结构-活性关系,并提出了结构简化建议。伞形酮和 2,4-二羟基苯乙酮为设计 SHC 抑制剂提供了方便的起始核。含有ω-环氧法呢酰基或只有普通烷基链的衍生物对在大肠杆菌中表达的重组 SHC 有抑制作用。
