A series of novel 2,4‐disubstituted 7‐methyl‐1,1,3‐trioxo‐2,4‐dihydro‐pyrazolo[4,5‐e] [1,2,4]thiadiazines (PTDs) was synthesized, structurally confirmed by spectral analysis, and evaluated for their anti‐HIV activities by inhibition of HIV‐induced cytopathogenicity in MT‐4 cell culture. The results showed that some compounds exhibited inhibitory activity specifically against HIV‐2 replication. The
合成了一系列新型 2,4-二取代 7-甲基-1,1,3-三氧代-2,4-二氢-吡唑并 [4,5-e] [1,2,4] 噻二嗪 (PTD),结构上通过光谱分析证实,并通过在 MT-4 细胞培养物中抑制 HIV 诱导的细胞致病性来评估它们的抗 HIV 活性。结果表明,一些化合物表现出特异性抑制 HIV-2 复制的活性。最活跃的 HIV-2 抑制剂是化合物 7i(R1 = 苄基,R2 = 4-叔丁基-苄基),EC50 值为 18.7 μM,SI = 15,这可能为进一步的分子优化提供有用的线索。
