Reaction of nordihydroguaiaretic acid with various alkyl chlorides, 1-piperidinecarbonyl chloride, methyl chloroformate, or 1,1′-carbonyldiimidazole under alkaline conditions produced the corresponding phenol ethers, carbamates and carbonates, respectively, in 67-83% yields (Scheme 1 and Scheme 2). Among these derivatives, the nitrogen-containing compounds were converted to the corresponding hydrochloride salts. Having good solubility, these NDGA derivatives were found to be stable in aqueous solution. These new compounds exerted potent activities against HIV Tat-regulated transactivation in cos-7 cells. The most active transcription inhibitor compound of this series 5b (P4N, Tetrapiperidino NDGA, meso-2,3-dimethyl-1,4-bis(3,4-[2-(piperidino)ethoxyphenyl])butane tetrakishydrochloride salt) has an IC50 of 0.88 μM.
在碱性条件下,Nordihydroguaiaretic酸与各种烷基氯化物、1-哌啶甲酰氯、氯甲酸甲酯或1,1'-卡邦二咪唑反应,分别产生相应的酚醚、氨基甲酸酯和碳酸酯,收率为67-83%(图1和图2)。在这些衍生物中,含氮化合物被转化为相应的盐酸盐。这些NDGA衍生物在水溶液中具有良好的溶解性和稳定性。这些新化合物对HIV Tat调控的cos-7细胞中的转录激活具有强效活性。该系列中最活跃的转录抑制剂化合物5b(P4N,四哌啶基NDGA,meso-2,3-二甲基-1,4-双(3,4-[2-(哌啶基)乙氧基]苯基)丁烷四盐酸盐)的IC50为0.88μM。
