                 下与芳香胺发生缩合反应合成了 34 个吲哚席夫碱类化合物。采用 FTIR、 HNMR、 CNMR 和 HRMS 对其结构
                 进行了表征,通过噻唑蓝(MTT)法测试了目标化合物在 MT-4 细胞内的抗 HIV-1 病毒株的活性。初步的生物
                 活性测试结果表明,这些吲哚席夫碱类化合物对 HIV-1 有良好的抑制活性。其中,1-(5-溴-1H-吲哚-3-基)-N-(2-
                 甲氧基苯基)甲亚胺〔31,  半最大效应浓度(EC 50 )= 0.06 μmol/L〕展现出了最强的抗 HIV-1ⅢB 活性,与阳性药
                 物地拉韦啶(DLV,EC 50  = 0.057 μmol/L)相当;同时,化合物 31(EC 50  < 0.09 μmol/L)还对病毒株 Clade A
                 (92UG029)、Clade B(92US657)、Clade C(93IN101)和 Clade E(93TH051)也表现出了抑制活性。化合物
                 31 具有低的毒性,其选择指数(SI)高于 2500.0,明显高于 DLV(SI = 1209.3)和依法韦仑(EFV, SI = 321.0),
                 可作为先导化合物进行深入研究。

                 Abstract: To discover highly effective, low-toxicity inhibitors of human immunodeficiency virus type 1
                 (HIV-1), thirty-four indole Schiff  base derivatives  were synthesized  by condensation between
                 3-indole-formaldehyde  derivatives with aromatic amines  under the catalysis of  base.  The structures of
                                                                 13

                 targeted compounds were characterized by FTIR,  HNMR,  CNMR and HRMS. The anti-HIV-1 activity of
                 the target compounds in  MT-4 cells  was evaluated  by thiazolyl blue (MTT) assay. The  preliminary
                 biological test results showed that these synthesized indole Schiff  base derivatives  had good inhibitory
                 effect  on  HIV-1 growth. Especially, 1-(5-bromo-1H-indol-3-yl)-N-(2-methoxyphenyl)methanimine [31,
                 concentration for 50% of maximal effect (EC 50) = 0.06 μmol/L] exhibited the strongest anti-HIV-1  ⅢB
                 activity,  which was  equipotent  to reference drug delavirdine (DLV, EC 50 =  0.057  μmol/L). Moreover,
                 compound 31 (EC 50 < 0.09 μmol/L) also showed inhibitory activities against Clade A (92UG029), Clade B
                 (92US657), Clade C (93IN101) and Clade E (93TH051). Furthermore, the toxicity of compound 31 was
                 low, and the selectivity index (SI) was higher 2500.0, which was significantly higher than those of DLV (SI
                 = 1209.3) and efavirenz (EFV, SI = 321.0), so compound 31 could be used as lead compound for further
                 research.
