Human respiratory syncytial virus (RSV), a paramyxovirus, is a major cause of acute upper and lower respiratory tract infections in infants, young children, and adults. RFI-641 is a novel anti-RSV agent with potent in vitro and in vivo activity. RFI-641 is active against both RSV type A and B strains. The viral specificity and the large therapeutic window… (More)
A series of substituted 4-anilino-7-phenyl-3-quinolinecarbonitriles has been prepared as Src kinase inhibitors. Optimal activity is observed with compounds that have basic amines attached via the para position of the 7-phenyl ring, and a hydrogen atom at the C-6 position. The best compounds are low nanomolar inhibitors of Src kinase, and have potent… (More)
The design and synthesis of a new potent and selective inhibitor of the respiratory syncytial virus are described. This compound, RFI-641, emerged from analysis of the structure-activity relationship in a series of biphenyl triazine anionic compounds possessing specific anti-RSV activity. The key synthetic step involves coupling of diaminobiphenyl 11 with… (More)
We disclose here a new class of kinase inhibitors, obtained by replacing the phenyl ring of a 3-quinolinecarbonitrile system with a thiophene ring. When suitably substituted, the resultant 7-phenylaminothieno[3,2-b]pyridine-6-carbonitrile analogues show potent inhibition of Src kinase activity.
The knowledge of SAR in a series of biphenyl anionic RSV inhibitors has been broadened by synthesis and testing of analogs with pyrimidine linkers. Generally, pyrimidine compounds were much harder to synthesize, and their anti-RSV activity was lower in comparison with triazine analogs.
