compound 8. In this paper, we report the discovery and optimization of a series of methylsulfonyl indazoles as potent RSV fusion inhibitors. In particular, compound 47 was orally efficacious in a RSV mouse model, with 1.6 log unit viral load reduction at 25 mg/kg BID upon oral dosing. The results may have broad implications for the design of new RSV fusion inhibitors, and demonstrate the potential for developing
最近,我们描述了一类新型的咪唑并吡啶化合物,它们在细胞培养中显示出非凡的抗RSV效力。然而,不利的药代动力学(PK)性质和谷胱甘肽(GSH)加合物的负债阻碍了它们的进一步发展。为了解决PK和早期安全问题,设计并合成了一个由数十个支架跳跃类似物组成的小型化合物文库,用于RSV CPE分析筛选,从而确定了一个新的化学起点:甲基磺酰基吲哚化合物8。在本文中,我们报告了一系列作为有效RSV融合抑制剂的甲基磺酰基吲唑的发现和优化。特别是化合物47在RSV小鼠模型中具有口服有效作用,口服剂量在25 mg / kg BID时可减少1.6 log单位的病毒载量。结果可能对新型RSV融合抑制剂的设计具有广泛的意义,并证明了开发针对RSV感染的新疗法的潜力。

Reactions of 3-amino-1-phenyl- and 3-amino-1-(thien-2-yl)-4,4,4-trifluorobut-2-en-1-ones with 1,2-diaminopropane and 1,2-diamino-3,3,3-trifluoropropane

The reactions of 3-amino-1-phenyl- and 3-amino-1-(thien-2-yl)-4,4,4-trifluorobut-2-en-1-ones with 1,2-diaminopropane under kinetically controlled conditions afford mixtures of cis and trans isomers of 2-aroylmethyl-4-methyl-2-trifluoromethylimidazolidines. Analogous reactions with 1,2-diamino-3,3,3-trifluoropropane yield cis-2-aroylmethyl-2,4-bis(trifluoromethyl)imidazolidines.
