  摘要：

  使用3-（1-ω-羧基烷基-2,3-二氢吲哚-1）分子内酯化反应获得基于bis-3,4（吲哚-1-基）马来酰亚胺骨架的15、16和17元内酯-基）-4-（1-ω-羟基烷基-2,3-二氢吲哚-1-基）-马来酰亚胺。3，4-二溴-马来酰亚胺，ω-（2，3-二氢吲哚-3-基）链烷酸和ω-（2，3-二氢吲哚-3-基）链烷醇用作起始化合物。Br取代取代的二氢吲哚，然后进行O-甲硅烷基化的羟基衍生物的分子内环化反应，形成了包含4-（二氢吲哚-1-基）-3-（吲哚-1-基）马来酰亚胺基团的大内酯。这些化合物中的二氢吲哚核在回流的甲苯中通过DDQ脱氢，得到15、16或17元内酯3-[（（ω-3-羧基烷基吲哚-1-基）-4-]（ω-羟基烷基吲哚-1-基）马来酰亚胺。G ＃和与目标反应产物的不存在相关。

  A parallel high throughput screening method on a solid support is disclosed that allows the detection of low affinity binding partners, comprising the steps of:(a) providing a library of different ligands;(b) forming a binding matrix comprising the ligands on a solid support by immobilising said ligands on the support; (c) contacting a target of interest with said binding matrix; (d) parallely determining a binding value of the ligand/target interaction for each type of ligand comprised in the binding matrix; (e) selecting those ligands the binding value of which in an immobilised state towards the target exceeds a predetermined threshold; (f) evaluating the affinity of each of the ligands selected in step (e) in a non-immobilised state towards the target; (g) identifying at least one ligand of step (f) as low affinity binding ligand.

  Substantially pure 3-(3-indolyl)propionic acid free acid is synthesized by converting the free acid to 3-(3-indolyl)propionic acid calcium salt (3-IPA calcium), precipitating and washing, and then reconverting the 3-IPA calcium to the free acid. 3-IPA calcium is suitable for use in pharmaceutical compositions in tablet and sustained-release dosage forms. 3-IPA calcium can be used to inhibit the cytotoxic effects of amyloid beta protein on cells, to treat fibrillogenic diseases in a mammal, and to treat diseases or conditions in which free radicals or oxidative stress plays a role.
