通过Pd-或Rh-或选择性亲电取代的方法合成了22个2-芳基- 1h -吲哚,其中包括12个新化合物。这三种方法都是基于简单吲哚前体的细化。对这些吲哚和2-苯基- 1h -吲哚在金黄色葡萄球菌中作为NorA外排泵抑制剂的SAR研究表明,5-硝基-2-(3-甲氧基羰基)苯基- 1h -吲哚是一种比先导物INF55稍强的抑制剂。此外,还发现了一种新的抗金黄色葡萄球菌先导化合物(2-苯基- 1h -吲哚-5-基)-甲醇。
The synthesis of 22 2-aryl-1H-indoles, including 12 new compounds, has been achieved via Pd- or Rh- mediated methodologies, or selective electrophilic substitution. All three methods were based on elaborations from simple indole precursors. SAR studies on these indoles and 2-phenyl-1H-indole in S. aureus as NorA efflux pump inhibitors indicated 5-nitro-2-(3-methoxycarbonyl)phenyl-1H-indole was a slightly more potent inhibitor than the lead INF55. A promising new antibacterial lead compound against S. aureus, (2-phenyl-1H-indol-5-yl)-methanol, was also found.
