  对多诺瓦尼利什曼原虫具有活性的新型苯基咪唑甲酰胺的先导优化

  摘要：

  内脏利什曼病是由寄生原生生物、多诺瓦尼利什曼原虫和婴儿利什曼原虫引起的潜在致命疾病。由于成本、住院需要、对不同物种的不同疗效、毒性和新出现的耐药性，目前的治疗仍然不合适。在此，我们报告了之前从高通量筛选中发现的新型命中 4-Fluoro- N- (5-(4-methoxyphenyl)-1-methyl-1 H -imidazole-2-yl)benzamide [ 1 ]的 SAR 探索针对布氏锥虫、克氏锥虫和多诺瓦尼利什曼原虫. 合成了一组广泛且信息丰富的类似物，在支架周围加入了关键修饰，从而提高了效力，而大多数化合物对作为这些病原体靶细胞的人类 THP-1 巨噬细胞保持低细胞毒性。本研究中鉴定的新先导化合物还保持了理想的物理化学性质，提高了体外代谢稳定性，并且对 HepG2 细胞系没有显着的线粒体毒性。该化合物类别值得继续研究，以开发作为内脏利什曼病的新疗法。

  Structure−Activity Relationship of 4(5)-Aryl-2-amino-1H-imidazoles, N1-Substituted 2-Aminoimidazoles and Imidazo[1,2-a]pyrimidinium Salts as Inhibitors of Biofilm Formation by Salmonella Typhimurium and Pseudomonas aeruginosa

  摘要：

  A library of 112 4(5)-aryl-2-amino-1H-imidazoles, 4,5-diphenyl-2-amino-1H-imidazoles, and N1-substituted 4(5)-phenyl-2-aminoimidazoles was synthesized and tested for the antagonistic effect against biofilm formation by Salmonella Typhimurium and Pseudomonas aeruginosa. The substitution pattern of the 4(5)phenyl group and the nature of the N1-substituent were found to have a major effect on the biofilm inhibitory activity. The most active compounds of this series were shown to inhibit the biofilm formation at low micromolar concentrations. Furthermore, the influence of 6 imidazo[1,2-a]pyrimidines and 18 imidazo[1,2-a]pyrimidinium salts on the biofilm formation was tested. These compounds are the chemical precursors of the 2-aminoimidazoles in our synthesis pathway. A good correlation was found between the activity of the imidazo[1,2-a]pyrimidinium salts and their corresponding 2-aminoimidazoles, supporting the hypothesis that the imidazo[1,2-a]pyrimidinium salts are possibly cleaved by cellular nucleophiles to form the active 2-aminoimidazoles. However, the imidazo[1,2-a]pyrimidines did not show any biofilm inhibitory activity, indicating that these molecules are not susceptible to in situ degradation to 2-aminoimidazoles. Finally, we demonstrated the lack of biofilm inhibitory activity of an array of 37 2N-substituted 2-aminopyrimidines, which are the chemical precursors of the imidazo[1,2-a]pyrimidinium salts in our synthesis pathway.

• A Divergent Synthesis of Substituted 2-Aminoimidazoles from 2-Aminopyrimidines
  作者：Denis S. Ermolat’ev、Erik V. Van der Eycken

  DOI：10.1021/jo8008758

  日期：2008.9.1

  A new divergent and efficient synthesis of substituted 2-aminoimidazoles 5 and 6 has been developed starting from the readily available 2-aminopyrimidines 1 and alpha-broinocarbonyl compounds 2, Using conventional heating or microwave irradiation. Thus, the cleavage of 1,2,3-substituted imidazo[1,2-a]pyrimidin-1 -iumsalts 4 with hydrazine or secondary amines led to 1,4,5-trisubstituted 2-aminoimidazoles 5, when the hydrazinolysis of 2-hydroxy-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-4-ium salts 3, followed by a novel Dimroth-type rearrangement, resulted in formation of 2-amino-1H-imidazoles 6. The relevant pathway of transformations was identified by characterization of the intermediates.
