It is an urgent need to develop more effective anti-influenza agents due to the emergence of highly pathogenic and drug-resistant influenza viruses. Herein, a series of 2,4-disubstituted quinazoline derivatives were designed, synthesized and their antiviral activities against influenza A virus were evaluated. Nine compounds (10a2, 16a, 16e, 16i, 16j, 16n, 16o, 16p and 16r) showed potent activity against influenza A virus (IAV) with IC50 at the low-micromole level (1.29–9.04 μM). Particularly, 16e and 16r possess good anti-IAV activity (IC50: 1.29 μM and 3.43 μM, respectively) and acceptable cytotoxicity, and inhibit the transcription and replication of viral RNA. Together with reasonable PK profiles of 16e, these results suggest their promising potential as candidates for further investigation.

Modification of amino acids is an important strategy in organic and bioorganic chemistry. In contrast to common side-chain functionalization, backbone modification is much less explored. Especially glycine units seem to be attractive and versatile since a wide range of functionality can be potentially introduced. We report here oxidative modification of glycinates that are stable and enable further functionalization. Selective glycinate enolate oxidation by TEMPO or a FeCp2PF6/TEMPO reagent combination provides stable alkoxyamines in good to excellent yields. The methodology is expanded to glycine-containing dipeptides demonstrating selective oxygenation at the glycine unit. The orthogonal reactivity potential of oxygenated glycines for transformation to other amino acid derivatives is explored.
