  Baker's yeast reduction of arylalkyl and arylalkenil γ- and δ-keto acids

  摘要：

  gamma- and delta-Lactones 5, 6, 13, 14, 15 and 16 were synthesized via baker's yeast reduction of the corresponding keto acids 3 ,4 and 9-12. The enantioselectivity of the reduction is strongly dependent on the nature of the keto acid: the delta-lactones were always obtained in an ee% higher than the gamma-lactones and ranging from 70% to 100%.

• Stereoselective synthesis of chiral δ-lactones <i>via</i> an engineered carbonyl reductase
  作者：Tao Wang、Xiao-Yan Zhang、Yu-Cong Zheng、Yun-Peng Bai

  DOI：10.1039/d1cc04542c

  日期：——

  A carbonyl reductase variant, SmCRM5, from Serratia marcescens was obtained through structure-guided directed evolution. The variant showed improved specific activity (U mg−1) towards most of the 16 tested substrates and gave high stereoselectivities of up to 99% in the asymmetric synthesis of 13 γ-/δ-lactones. In particular, SmCRM5 showed a 13.8-fold higher specific activity towards the model substrate

  来自粘质沙雷氏菌的羰基还原酶变体Sm CR M5是通过结构引导的定向进化获得的。该变体对 16 种测试底物中的大多数表现出改善的比活性 (U mg -1 )，并在 13 种 γ-/δ-内酯的不对称合成中提供高达 99% 的高立体选择性。特别是，SmCR M5对模型底物（即5-氧代癸酸）的比活性高出 13.8 倍，并在 99% ee 中产生 ( R )-δ-癸内酯，时空产率 (STY) 为 301 g L -1 d -1. 六种δ-内酯的高收率和高对映体纯度的制备表明这些高附加值化学品的生物催化合成是可行的，为贵金属催化提供了一种具有成本效益的绿色替代品。
• Cytotoxic activity of (S)-goniothalamin and analogues against human cancer cells

  (R)- and (S)-Goniothalamin (1) and analogues 2-9 were efficiently prepared in high overall yield and enantiomeric purity, and their cytotoxic activities were evaluated against eight human cancer cell lines. A structure-activity relationship study (SAR) allowed us to establish the relevant structural features for the cytotoxic activity of goniothalamin analogues. In addition, we have identified non-natural form of goniothalamin (S)-1 and analogue 5 as the highest and more selective cytotoxic compounds against kidney cancer cell growth (786-0) with IC50 = 4 and 5 nM, respectively, and compound 8 (IC50 = 4 nM) as the more potent against breast cancer cells with resistance phenotype for adryamycin (c) 2005 Elsevier Ltd.
