A series of 1, 1'-biphenyl-2, 6-dicarboxylic acid diesters were synthesized and examined for their inhibitory activity on guinea-pig detrusor muscle contraction at electrical field stimulation in vitro. Among them, 6-isopropyl 2-methyl 3-hydroxy-5-methyl-2'-nitro-(1, 1'-biphenyl)-2, 6-dicarboxylate, FR75513 (8a) was one of the potent compounds (IC50=3.3×10-6 g/ml). This compound (8a) exhibited a strong inhibitory activity on detrusor contraction after intravenous administration in anesthetized rats (ID50=0.04 mg/kg).
研究人员合成了一系列 1,1'-联苯-2,6-二羧酸二酯,并考察了它们在体外电场刺激下对豚鼠逼尿肌收缩的抑制活性。其中,2-甲基-3-羟基-5-甲基-2'-硝基-(1, 1'- 联苯)-2, 6-二甲酸 6-异丙酯,FR75513(8a)是强效化合物之一(IC50=3.3×10-6 g/ml)。麻醉大鼠静脉注射该化合物(8a)后,其对逼尿肌收缩有很强的抑制作用(ID50=0.04 mg/kg)。
