高通量筛选(HTS)先前确定苯并咪唑1 (JMN3-003)是一种对不同流感病毒和副粘病毒株具有广泛抗病毒活性的化合物。为了从这个系列中寻找一种先导化合物进行开发,我们试图提高1的效价和水溶性。Lead优化已经获得了对黏液病毒家族成员具有有效抗病毒活性的化合物(EC50值在低纳摩尔范围内),并且相对于1的水溶性大大提高。此外,我们设计了一种强大的合成策略,以富集对映体的方式制备1和同族物,这使我们能够证明(S)-对映体通常比相应的(R)-异构体强7- 110倍。
High-throughput screening (HTS) previously identified benzimidazole 1 (JMN3-003) as a compound with broad antiviral activity against different influenza viruses and paramyxovirus strains. In pursuit of a lead compound from this series for development, we sought to increase both the potency and the aqueous solubility of 1. Lead optimization has achieved compounds with potent antiviral activity against a panel of myxovirus family members (EC50 values in the low nanomolar range) and much improved aqueous solubilities relative to that of 1. Additionally, we have devised a robust synthetic strategy for preparing 1 and congeners in an enantio-enriched fashion, which has allowed us to demonstrate that the (S)-enantiomers are generally 7- to 110-fold more potent than the corresponding (R)-isomers.
