  An α-acetoxy ketone reducing enzyme has been purified and characterized from the cell-free extract of bakers’ yeast (Saccharomyces cerevisiae). Only one NADPH-dependent dehydrogenase that catalyzed the reduction of α-acetoxy ketone was found in bakers’ yeast. The molecular weight of the enzyme was estimated to be 36 kDa by SDS-polyacrylamide gel electrophoresis. The enzyme was composed of a single

  已经从面包酵母（酿酒酵母）的无细胞提取物中纯化并表征了 α-乙酰氧基酮还原酶。在面包酵母中只发现了一种催化 α-乙酰氧基酮还原的 NADPH 依赖性脱氢酶。通过SDS-聚丙烯酰胺凝胶电泳估计酶的分子量为36kDa。该酶由单个多肽链组成。该酶对脂肪族和芳香族 α-乙酰氧基酮均具有还原活性，但未发现对 α-氯酮和 α-羟基酮有还原活性。该酶不仅催化 α-乙酰氧基酮的还原，还催化 β-酮酯的还原。对色谱行为和立体特异性的研究表明，该酶与从面包酵母中纯化的一种 β-酮酯还原酶相同。

  The bakers’ yeast reduction of a series of 2-oxoalkyl arenecarboxylates [R(C=O)CH2O(C=O)C6H4-p-X] (1a–f) (R = CH3 to n-C6H13; X = H) and the phenyl-modified derivatives (1g–l) (R = n-C5H11, X = OH, CH3, F, Cl, Br, or I) as well as 1-chloro-2-alkanones R(C=O)CH2Cl (6a–f) (R = CH3 to n-C6H13) were systematically investigated. The substrate specificities, configuration and %ee of the reduction products were found to be highly dependent on the length of the alkyl group (R) and the α substituent. Thus, the benzoates 1a–f gave optically active 2-hydroxyalkyl benzoates (2a–f) (R, configuration, %ee) (a: CH3, S, 99; b: C2H5, S, 98; c: C3H7, S, 26; d: n-C4H9, R, 55; e: n-C5H11, S, 15; f: n-C6H13, S, 63) in 11–91% yields. Among the modification experiments of the phenyl group, 1g–l, the p-iodo substituent markedly increased the ee from 15 to 71%, although the yield was rather lowered (22% yield). The reduction of α-chloro ketones 6a–f also gave optically active 1-chloro-2-alkanols (7a–f) [(R, configuration, %ee) (a: CH3, S, 83; b: C2H5, S, 54; c: C3H7, R, 49; d: n-C4H9, R, 80; e, n-C5H11, R, 65; f, n-C6H13, R, 41)] in 16–69% yields.

  对一系列2-氧代烷基苯甲酸酯[R(C=O)CH2O(C=O)C6H4-p-X]（1a-f）（R = CH3 至 n-C6H13；X = H）和苯基修饰衍生物（1g-l）（R = n-C5H11，X = OH、CH3、F、Cl、Br 或 I）以及1-氯-2-烷酮R(C=O)CH2Cl（6a-f）（R = CH3 至 n-C6H13）的面包酵母还原进行了系统研究。发现底物特异性、构型和还原产物的%ee高度依赖于烷基链的长度（R）和α取代基。因此，苯甲酸酯1a-f得到了光学活性的2-羟基烷基苯甲酸酯（2a-f）（R，构型，%ee）（a：CH3，S，99；b：C2H5，S，98；c：C3H7，S，26；d：n-C4H9，R，55；e：n-C5H11，S，15；f：n-C6H13，S，63），产率为11-91%。在苯基修饰实验中，1g-l，碘取代基显著提高了ee值，从15%增加到71%，尽管产率明显下降（产率22%）。α-氯代酮6a-f的还原也得到了光学活性的1-氯-2-烷醇（7a-f）[（R，构型，%ee）（a：CH3，S，83；b：C2H5，S，54；c：C3H7，R，49；d：n-C4H9，R，80；e，n-C5H11，R，65；f，n-C6H13，R，41）]，产率为16-69%。

  Many 1-substituted 2-alkanone derivatives were synthesized and their inhibitory activities toward pancreatic lipase and esterase were examined in order to obtain hypolipidemic agents. 1-Benzenesulfonyloxy-2-pentanone (VI-2a) and 1-(2, 4, 6-trimethylbenzenesulfonyloxy)-2-pentanone (VI-2q) exhibited not only potent and selective esterase inhibitions (IC50 : 9.0×10-7M and 1.0×10-6M, respectively), but also potent hypolipidemic action (90 and 92% reductions of plasma triglyceride, and 53 and 90% reductions of plasma total cholesterol, respectively). A novel working hypothesis is presented to account for the lowering of the plasma lipids level, i.e., that inhibition of esterase and lipase activities in the small intestinal lumen may be responsible for the decrease in the plasma lipids level.

  合成了许多1-取代的2-酮烷基衍生物，并考察了它们对胰脂肪酶和酯酶的抑制活性，以期获得降脂药物。1-苯磺酰氧基-2-戊酮（VI-2a）和1-(2, 4, 6-三甲基苯磺酰氧基)-2-戊酮（VI-2q）不仅表现出显著且具有选择性的酯酶抑制（IC50：9.0×10^-7M 和 1.0×10^-6M），而且还具有强效的降脂作用（血浆甘油三脂分别减少90%和92%，血浆总胆固醇分别减少53%和90%）。提出了一个新的工作假设来解释血浆脂质水平的降低，即小肠腔内酯酶和脂肪酶活性的抑制可能是导致血浆脂质水平下降的原因。
