A series of 4-substituted 3,4-dihydropyrimidine-2-ones (DHPM) was synthesized, characterized by IR, 1H NMR, 13C NMR and HRMS spectra. The compounds were evaluated in vitro for their antiviral activity against a broad range of DNA and RNA viruses, along with assessment for potential cytotoxicity in diverse mammalian cell lines. Compound 4m, which possesses a long lipophilic side chain, was found to
合成了一系列的4-取代的3,4-二氢嘧啶-2-酮(DHPM),并通过IR,1 H NMR,13 C NMR和HRMS光谱进行了表征。在体外评估了这些化合物对各种DNA和RNA病毒的抗病毒活性,并评估了多种哺乳动物细胞系中潜在的细胞毒性。具有长亲脂性侧链的化合物4m被发现是一种有效且选择性的Punta Toro病毒抑制剂,该病毒是Bunyaviridae的成员。对于裂谷热病毒(另一种布尼亚病毒)而言,4m的活性可忽略不计。具有带有卤素取代基的C-4芳基部分的DHPM(4b,4c和4d)被发现在MT4细胞中具有细胞毒性。
