A Convenient Synthesis of 2-Phenylbenzofuran Derivatives with Potent Testosterone 5a-Reductase Inhibitory Activities
摘要:
A convenient method for the synthesis of 4-[2-(benzo[b]furan-2-yl)phenyloxy]butyric acid derivatives with a carbamoyl group at the 5 or 6 position of the benzofuran ring showing potent 5 alpha-reductase inhibitory activities was developed. Oxazolin-2-ylbenzofuran derivatives were treated with tert-BuLi followed by tri(n-butyl)tin chloride, to give 2-tri(1-butyl)stannylbenzofuran derivatives. A palladium-catalyzed cross-coupling reaction of these benzofuran derivatives with tert-butyl 4-(2-iodophenyloxy)butyrate afforded the 2-phenyl benzofuran compounds in good yields.

A novel scaffold with different tails: hCA II and hCA XIIisoforms are involved in the production aqueous humor, and represent attractive therapeutic targets for antiglaucoma drugs. By using a tail approach on a newly designed thiadiazol-benzenesulfonamide scaffold, we hereby identified novel hCA II and XIIinhibitors that warrant further chemical development as novel candidates for antiglaucoma drug
具有不同尾部的新型支架:hCA II 和 hCA XII 亚型参与房水的产生,代表抗青光眼药物有吸引力的治疗靶点。通过在新设计的噻二唑-苯磺酰胺支架上使用尾部方法,我们特此鉴定出新型 hCA II 和 XII 抑制剂,这些抑制剂值得进一步化学开发,作为抗青光眼药物开发的新候选药物。
