The RNA-dependent transcriptase of influenza virus is an attractive antiviral target, still not addressed by any commercialized drugs. Flutimide, a fungal metabolite, comprising an unusual 2,6-diketopiperazine core has earlier been shown to inhibit the endonuclease activity of influenza transcriptase. In this paper we present a novel synthetic approach to 2,6-diketopiperazines, based on the rearrangement
流感病毒的RNA依赖性转录酶是有吸引力的抗病毒靶标,目前尚无任何商品化药物解决。Flutimide是一种真菌代谢产物,包含不寻常的2,6-二酮哌嗪核心,已被证明可抑制流感病毒转录酶的核酸内切酶活性。在本文中,我们基于2-酰基-5-芳基-3,5-二氢-4 H-咪唑-4-酮的重排以及合成和抗流感评估,提出了一种新颖的2,6-二酮哌嗪合成方法一系列新颖的氟啶胺类似物。
