  Carbamoyl Pyridone HIV-1 Integrase Inhibitors 3. A Diastereomeric Approach to Chiral Nonracemic Tricyclic Ring Systems and the Discovery of Dolutegravir (S/GSK1349572) and (S/GSK1265744)

  摘要：

  We report herein the discovery of the human immunodeficiency virus type-1 (HIV-1) integrase inhibitors dolutegravir (S/GSK1349572) (3) and S/GSK1265744 (4). These drugs stem from a series of carbamoyl pyridone analogues designed using a two-metal chelation model of the integrase catalytic active site. Structure-activity studies evolved a tricyclic series of carbamoyl pyridines that demonstrated properties indicative of once-daily dosing and superior potency against resistant viral strains. An inherent hemiaminal ring fusion stereocenter within the tricyclic carbamoyl pyridone scaffold led to a critical substrate controlled diastereo-selective synthetic strategy whereby chiral information from small readily available amino alcohols was employed to control relative and absolute stereochemistry of the final drug candidates. Modest to extremely high levels of stereochemical control were observed depending on ring size and position of the stereocenter. This approach resulted in the discovery of 3 and 4, which are currently in clinical development.

  红球菌 erythropolisSET1 的底物评估，一种腈水解细菌，显示出强烈依赖于腈亚结构的双重活性

  摘要：

  红球菌 SET1 是一种新型腈水解细菌分离株，已使用 34 种腈、33 种手性和 1 种前手性进行了评估。这些底物主要由 β-羟基腈组成，在 β 位具有不同的烷基和芳基，并且在几种化合物中含有与腈不同的 α 取代基。在 α 位没有取代的 β-羟基腈的情况下，由于分离物的腈水解酶活性，酸是获得的主要产物，以及生物转化后回收的腈。出乎意料的是，当 β-羟基腈在该位置具有乙烯基时，发现酰胺是主要的水解产物。为了进一步探索这种行为，评估了在 α 位置包含吸电子基团的其他相关底物，在 SET1 存在下的生物转化过程中也观察到了酰胺。因此，这种新的分离物也证明了对似乎是底物依赖性的腈类的 NHase 活性。

  日期：2006.3

  Halohydrin dehalogenases (HheA, HheB and HheC) were found to efficiently catalyse a carbon-carbon bond forming reaction between terminal aliphatic epoxides and cyanide, yielding β-hydroxy nitriles. With all three enzymes nucleophilic ring opening of epoxides proceeds with high regioselectivity to the β-carbon atom. Activity, enantioselectivity and enantiopreference depend on the type of enzyme and

• Thiacrown Ether Technology in Lipase-Catalyzed Reaction:  Scope and Limitation for Preparing Optically Active 3-Hydroxyalkanenitriles and Application to Insect Pheromone Synthesis
  作者：Toshiyuki Itoh、Koichi Mitsukura、Wipa Kanphai、Yumiko Takagi、Hiroshi Kihara、Hiroshi Tsukube

  Both reaction rate and enantioselectivity in Pseudomonas cepacia lipase (PCL)-catalyzed hydrolysis of 3-hydroxyalkanenitrile acetates were significantly changed by the addition of catalytic amounts of thiacrown ether (1,4,8,11-tetrathiacyclotetradecane). Although the-reaction rate of various nitriles was accelerated, the enantioselectivity greatly depended on the nature of the substrate. Among 10 substrates tested, thiacrown ether offered highest enantioselectivity in PCL-catalyzed hydrolysis of 1-(cyanomethyl)propyl acetate. Forty or more times this crown ether, molarity based on the enzyme, was required to attain an acceptably high reaction rate and enantioselectivity. Applying this technology, we succeeded in synthesizing the optically pure attractant pheromone of ant Myrmica scabrinodis (A), (R)-3-octanol and its antipode of (S)-isomer in good overall yields.
