A new series of heterocyclic ring-containing benzoic acids was prepared, and the binding affinity and antagonism of its members against all-trans-retinoic acid were evaluated by in vitro assay systems using human promyelocytic leukemia (HL-60) cells. Structure-activity relationships indicated that both an N-substituted pyrrole or pyrazole (1-position) and a hydrophobic region, with these linked by
制备了一系列新的含杂环苯甲酸,并通过体外检测系统使用人类早幼粒细胞白血病(HL-60)细胞评估了其成员对全反式维甲酸的结合亲和力和拮抗作用。结构活性关系表明,N-取代的吡咯或吡唑(1-位)和疏水区(通过环系统连接)对于有效拮抗都是必不可少的。在所评估的化合物中,最佳拮抗作用是通过4- [4,5,7,8,9,10-六氢-7,7,10,-10-四甲基-1-(3-吡啶基甲基)蒽[1,2 -b]吡咯-3-基]苯甲酸(31),4- [4,5,7,8,9,10-六氢-7,7,10,10-四甲基-1-(3-吡啶基甲基)- 5-硫杂蒽[1,2-b]吡咯-3-基]苯甲酸(40)和4- [4,5,7,8,9,10-六氢-7,7,10,10-四甲基- 1-(3-吡啶基甲基)蒽[2,
