标题:轻触发的硫代马来酰亚胺环水解稳定快速地合成巯基
摘要:马来酰亚胺介导的生物分子巯基特异性衍生化是目前可用的最有效的生物缀合方法之一.然而,令人震惊的是,最近的研究表明,所得的硫代马来酰亚胺共轭物易于通过硫醇交换反应分解.在此,我们报道了一种新的马来酰亚胺,即o-Ch 2 Nh Ipr苯基马来酰亚胺,在巯基结合后会经历前所未有的快速环水解,形成稳定的耐巯基交换抗性的偶联物.此外,我们通过开发抗环水解的光笼型支架,克服了由于马来酰亚胺试剂在生物缀合之前易于发生环水解的问题,从而克服了马来酰亚胺试剂保质期低的问题.用这种光笼封的马来酰亚胺形成的硫醇生物共轭物的紫外线照射可在温和,冰冷的条件下1小时内迅速释放出硫代马来酰亚胺环,从而产生所需的稳定共轭物.

标题:Process for the synthesis of curcumin-related compounds
发明人：KRACKOV MARK HARRY; BELLIS HAROLD EDWARD
权利人:GENE PRINT INC
摘要:The invention is directed to a process for the synthesis of curcumin and curcumin-related compounds by reacting the enol form of a 2,4-diketone with a monocarbocyclic aldehyde in the presence of an organic amine catalyst. The reactants are dissolved in a highly polar, aprotic organic solvent. The curcumin-related product is recovered in crystalline form by precipitation from the reaction mass and solvent recrystallization.
