A series of 3-phosphonylated thiazolo[3,2-a]oxopyrimidines 3a-k was synthesized for the first time by the reactions of chloroethynylphosphonates with 5,6-disubstituted 2-thiouracils. In vitro antiviral activities have shown that the compounds 1i, 1j, 3b and 3e were shown activity against influenza A virus. In vitro antitumor activity was conducted for all compounds against human erythroleukemia (K562)

嘧啶3a-k。体外抗病毒活性表明化合物1i、1j、3b和3e显示出抗甲型流感病毒的活性。通过
MTS 测定对所有化合物对人红白血病 (K562) 和宫颈癌 (HeLa)
细胞系进行体外抗肿瘤活性。在靶向化合物3c 中,3h和3j对人红白血病 (K562)
细胞系具有活性,而3c和3j对宫颈癌 (HeLa)
细胞系有活性。发现用化合物3c和3j处理后的 HeLa 细胞显着减少了具有应力纤维和丝状伪足样膜突起的细胞数量。得出的结论是,靶向化合物具有抑制细胞生长的作用,这可能导致肌动蛋白丝的形成减少以及丝状伪足样膜突起的数量减少。
