  Synthesis of Sulfur- and Sulfoxide-Substituted 2,3-Oxidosqualenes and Their Evaluation as Inhibitors of 2,3-Oxidosqualene-Lanosterol Cyclase

  摘要：

  2,3-Oxidosqualene (23-OS) analogs that contain thioether (52-55) and sulfoxide (56-60) at positions normally occupied by carbons considered to be cationic during 2,3-oxidosqualene-lanosterol cyclase (OSC) cyclization (C-6, C-10, C-14, and C-19) were synthesized and tested as substrate mimic inhibitors of fungal and mammalian OSC. The analogs were found to be potent inhibitors of cyclase in cell-free extracts of Candida albicans and rat liver. Thioether analogs were more potent than the corresponding sulfoxides. In both series, those 2,3-OS analogs containing a sulfur at the position normally occupied by C-19 were the most potent. With C. albicans cyclase, the IC50 for thioether 55 was 0.0023 mu M while 60 exhibited an IC50 of 0.065 mu M, which are the lowest values reported for a inhibitor of this enzyme. Similarly, thioether 55 displayed an IC50 of 0.00082 mu M for rat liver cyclase which is the best inhibitor up to date for this enzyme. These results suggest that mimics with modification in the region of C-19 of 2,3-OS have a high affinity for the active site of these enzymes. The same series of analogs (52-60) were also tested for inhibition of cholesterol biosynthesis in intact MDBK (Madin Darbin bovine kidney) cells and for in vitro antifungal activity against C. albicans.

  aminolysis of 3,4‐epoxy amines has been achieved. Key features of this reaction are (1) chemoselective activation of epoxides in the presence of unprotected aliphatic amines in the same molecules by a La(OTf)3 catalyst and (2) excellent regioselectivity for anti‐Baldwin 5‐endo‐tet cyclization. This reaction affords 3‐hydroxy‐2‐alkylpyrrolidines stereospecifically in high yields. DFT calculations revealed

  已经实现了3,4-环氧胺的高度区域选择性的分子内氨解。该反应的主要特征是（1）在由拉（OTF）存在下，在相同的分子无保护的脂族胺的环氧化物的化学选择性活化3抗鲍德温-5-催化剂和（2）优良的区位选择性内切- TET环化。该反应可立体高产率提供3-羟基-2-烷基吡咯烷。DFT计算表明，区域选择性可能归因于环氧胺底物的变形能。该反应的使用通过抗痉挛剂溴化芬尼的首次对映选择性合成得到证明。
