  制备3-（3-吲哚基）乳酸。_一种新的rac - Blepharismon的合成，日本Blepharisma japonicum的低分子量缀合物

  摘要：

  3-（3-吲哚基）乳酸衍生物的强大而多样的合成方法尤其可以提供rac-blepharismismone（7）及其类似物的通道。Blepharismon诱导了接合，导致纤毛虫Blepharisma japonicum [以前为B. Intermedium（Bhandary）]发生核交换。将3位未取代的吲哚1与rac-2,3-环氧丙酸甲酯（2）烷基化，得到rac-3（3-吲哚基）乳酸甲酯，可以很容易地将其皂化得到相应的酸4。用5-苄氧基吲哚（1b）可得到rac3-（5-羟基-3-吲哚基）乳酸（5），这是睑肌酮生物合成中的一种可能的前体。通过臭氧分解和氢解裂解吡咯系统，得到（甲酰胺基）苯甲酮衍生物6。用1b可以通过这种方式获得11％rac-blepharismone（7）。总产量。

  Renal-selective prodrugs are described which are preferentially converted in the kidney to compounds capable of inhibiting synthesis of catecholamine-type neurotransmitters involved in renal sympathetic nerve activity. The prodrugs described herein are derived from inhibitor compounds capable of inhibiting one or more of the enzymes involved in catecholamine synthesis, such compounds being classifiable as tyrosine hydroxylase inhibitors, or as dopa-decarboxylase inhibitors, or as dopamine-&bgr;-hydroxylase inhibitors. These inhibitor compounds are linked to a chemical moiety, such as a glutamic acid derivative, by a cleavable bond which is recognized selectively by enzymes located predominantly in the kidney. The liberated inhibitor compound is then available in the kidney to inhibit one or more of the enzymes involved in catecholamine synthesis. Inhibition of renal catecholamine synthesis can suppress heightened renal nerve activity associated with sodium-retention related disorders such as hypertension. Conjugates of particular interest are glutamyl derivatives of dopamine-&bgr;-hydroxylase inhibitors, of which N-acetyl-&ggr;-glutamyl fusaric acid hydrazide (shown below) is preferred. 1

  本文描述了一种肾选择性的前药，其在肾脏中优先转化为能够抑制参与肾交感神经活动的儿茶酚型神经递质合成的化合物。本文所描述的前药来源于能够抑制儿茶酚合成中的一个或多个酶的抑制剂化合物，这些化合物可分类为酪氨酸羟化酶抑制剂，多巴脱羧酶抑制剂或多巴胺-&bgr;-羟化酶抑制剂。这些抑制剂化合物通过可被肾脏中大量存在的酶选择性识别的可裂解键与化学基团（如谷氨酸衍生物）连接。释放的抑制剂化合物然后可在肾脏中用于抑制儿茶酚合成中的一个或多个酶。抑制肾脏儿茶酚合成可抑制与钠潴留相关的疾病（如高血压）相关的增强肾脏神经活动。特别感兴趣的共轭物是多巴胺-&bgr;-羟化酶抑制剂的谷氨酰衍生物，其中N-乙酰-&ggr;-谷氨酰富萨酸肼（如下图所示）是首选。1

  (EN) Renal-selective prodrugs are described which are preferentially converted in the kidney to compounds capable of inhibiting synthesis of catecholamine-type neurotransmitters involved in renal sympathetic nerve activity. The prodrugs described herein are derived from inhibitor compounds capable of inhibiting one or more of the enzymes involved in catecholamine synthesis, such compounds being classifiable as tyrosine hydroxylase inhibitors, or as depa-decarboxylase inhibitors, or as dopamine-$g(b)-hydroxylase inhibitors. These inhibitors compounds are linked to a chemical moiety, such as a glutamic acid derivative, by a cleavable bond which is recognized selectively by enzymes located predominantly in the kidney. The liberated inhibitor compound is then available in the kidney to inhibit one or more of the enzymes involved in catecholamine synthesis. Inhibition of renal catecholamine synthesis can suppress heightened renal nerve activity associated with sodium-retention related disorders such as hypertension. Conjugates of particular interest are glutamyl derivatives of dopamine-$g(b)-hydroxylase inhibitors, of which N-acetyl-Y-glutamyl fusaric acid is preferred.(FR) Sont décrits des promédicaments à sélectivité rénale qui sont préférentiellement transformés dans le rein en des composés capables d'inhiber la synthèse des neurotransmetteurs de type catécholamine impliqués dans l'activité rénale du nerf sympathique. Les promédicaments décrits ici sont dérivés de composés de l'inhibiteur capable d'inhiber un ou plusieurs enzymes impliqués dans la synthèse de la catécholamine, ces composés étant classifiables comme des inhibiteurs de tyrosine hydroxylase, ou comme des inhibiteurs de dépa-décarboxylase, ou comme des inhibiteurs de dopamine-$g(b)-hydroxylase. Ces composés d'inhibiteurs sont liés par une fraction de molécule chimique, comme un dérivé d'acide glutamique, par une liaison divisible qui est reconnue de manière sélective par des enzymes situés surtout sur le rein. Le composé d'inhibiteur libéré est alors disponible dans le rein pour inhiber un ou plusieurs des enzymes impliqués dans la synthèse de la catécholamine. L'inhibition de la synthèse rénale de la catécholamine peut supprimer l'activité rénale élevée du nerf associée aux désordres liés à la rétention de sodium tels que l'hypertension. Des conjugués d'un intérêt tout particulier sont les dérivés de glutamyle des inhibiteurs de dopamine-$g(b)-hydroxylase, et de préférence ceux d'acide fusarique N-acétyle-Y-glutamyle.
