Indole Derivatives Bearing Imidazole, Benzothiazole-2-Thione or Benzoxazole-2-Thione Moieties—Synthesis, Structure and Evaluation of Their Cytoprotective, Antioxidant, Antibacterial and Fungicidal Activities
combining two molecules with biological properties into a new hybrid molecule was used to design and synthesize of a series of ten indole derivatives bearing imidazole, benzothiazole-2-thione, or benzoxazole-2-thione moieties at the C-3 position. The compounds were spectroscopically characterized and tested for their antioxidant, antibacterial, and fungicidal activities. The crystal structures were determined

indole alkaloids that exhibit anti‐inflammatory and anti‐cancer effects. Herein, we report on a new, mild and efficient copper(II)‐promoted decarboxylative coupling reaction of 2‐(1H‐indol‐3‐yl)acetic acid derivatives (1 a–h) with a variety of (substituted) indoles (2 a–t) yielding (un)symmetrically substituted DIMs (3 a–z, 3 aa–ai). Reaction of 2‐(1H‐indol‐3‐yl)acetic acid (1 a) with 7‐azaindole led to
3,3'-二吲哚基甲烷(DIM)是一类重要的吲哚生物碱,具有抗炎和抗癌作用。在此,我们报道了一种新的,温和有效的,由铜(II)促进的2-(1 H-吲哚-3-基)乙酸衍生物(1 a – h)与多种(取代的)吲哚的脱羧偶联反应(2 a – t)产生(非)对称取代的DIM(3 a – z,3 aa – ai)。2-(1 H-吲哚-3-基)乙酸(1 a)与7-氮杂吲哚的反应生成3,3 '连接的DIM类似物5 d时,4,5和6氮杂吲哚与苯并咪唑在N 1氮原子上反应。1 a与1 H-吲唑反应生成1和2-取代的吲唑衍生物的混合物。这种新方法可以大规模合成具有生物活性的DIM。
Synthesis, Structure and Biological Activity of Indole–Imidazole Complexes with ZnCl2: Can Coordination Enhance the Functionality of Bioactive Ligands?
the indole–imidazole hybrid ligands to coordinate with the Zn(II) ion and the resulting structures of this new class of coordination compounds were analyzed in order to determine their structural properties and biological functionalities. For this purpose, six novel Zn(II) complexes, [Zn(InIm)2Cl2] (1), [Zn(InMeIm)2Cl2] (2), [Zn(IniPrIm)2Cl2] (3), [Zn(InEtMeIm)2Cl2] (4), [Zn(InPhIm)2Cl2] (5) and [Zn2(InBzIm)2Cl2]
