  Umbelliferone aminoalkyl derivatives, a new class of squalene-hopene cyclase inhibitors

  摘要：

  The synthesis is described of several aminoalkyl derivatives of coumarin, obtained in good yields under microwave or high-intensity ultrasound irradiation. These compounds proved uniformly active as inhibitors of squalene-hopene cyclase (SHC) from Alicyclobacilhis acidocaldarius. Their design stemmed from our recent finding that the umbelliferone nucleus acquires inhibitory properties towards SHC when functionalized with a suitable chain such as the omega-epoxyfarnesyl group. Under our experimental conditions the most active ones, such as 7-(4'-allyimethylamino-but-2-ynyloxy)chromen-2-one (IC50 0.75 mM), approached the potency of anticholesteremic drug Ro 48-8071 (IC50 0.35 mM), an effective inhibitor of both squalene- and oxidosqualene-cyclases (OSC). Tests are in progress to determine their efficacy on different eukaryotic OSCs. (C) 2004 Elsevier SAS. All rights reserved.

  摘要：

  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。

  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.

  In this study, we report on a system consisting of self-assembled monolayers (SAMs) formed by 7-(11-trichlorosilylundecyloxy)coumarin on mica and oil quartz glass. For the first time, in the absence of all inert atmosphere or a stabilizing matrix, we demonstrate by means of absorption and fluorescence spectroscopy that the photochemical cycloaddition of coumarin head groups is Completely reversible in SAMs. Photodimerization and photocleavage were monitored for Five cycles of alternating irradiation with light of wavelengths 355 and 254 nm, respectively. SAM formation was analyzed using atomic force microscopy and contact angle measurements. The quantum yield of the single photon absorption induced photocleavage Of coumarin dimers in a SAM was determined to be Phi = 0.29. Asymmetrical photocleavage after lactone ring-opening of the coumarin dimer SAM causes a change in contact angle from about 70 degrees to about 55 degrees. This may be observed, for example, as a significant change in surface wettability.
