制备方法与用途

生物活性

RSV604（A-60444）是一种新型苯二氮卓类药物，作为呼吸道合胞病毒 (RSV) 的抑制剂，其半数有效浓度 (EC50) 为 0.86 μM。这种化合物具有潜在的治疗 RSV 相关疾病的可能性，并已进入二期临床试验。

靶点

Target	Value
RSV (Cell-free assay)	0.86 μM (EC50)

体外研究

RSV604 在五天内抑制了四种实验室株 RSV（RSS、Long、A2 和 B）的生长，其在斑块减少试验中的 EC50 值范围为 0.5 至 0.9 μM。此外，RSV604 六天后抑制了由 RSV 引起的 HEp-2 细胞死亡，EC50 为 0.86 μM。在三天内，RSV604 减少了 RSV 感染的 HEp-2 细胞中的病毒抗原合成，其 EC50 为 1.7 μM。当 RSV604 在人类气道上皮细胞 (HAE) 中以 1 至 20 μM 浓度作用七天时，剂量依赖性地抑制了 RSV 感染，且未观察到明显的细胞毒性、基底液向顶面泄漏或纤毛搏动频率改变。

  1,4-Benzodiazepines as Inhibitors of Respiratory Syncytial Virus. The Identification of a Clinical Candidate

  摘要：

  Respiratory syncytial virus (RSV) is the cause of one-fifth of all lower respiratory tract infections worldwide and is increasingly being recognized as representing a serious threat to patient groups with poorly functioning or immature immune systems. Racemic 1,4-benzodiazepines show potent anti-RSV activity in vitro. Anti-RSV evaluation of 3-position R- and S-benzodiazepine enantiomers and subsequent optimization of this series resulted in selection of a clinical candidate. Antiviral activity was found to reside mainly in the S-enantiomer, and the R-enantiomers were consistently less active against RSV. Analogues of 1,4-(S)-benzodiazepine were synthesized as part of the lead optimization program at Arrow and tested in the XTT assay. From this exercise, (S)-1-(2-fluorophenyl)-3-(2-oxo-5-phenyl-2,3-dihydro-1H-benzo[e][1,4]-diazepin-3-yl)-urea, 17b (RSV-604) was identified as a clinical candidate, exhibiting potent anti-RSV activity in the XTT assay, which was confirmed in secondary assays. Compound 17b also possessed a good pharmacokinetic profile and has now progressed into the clinic.
