儿童最常见的颅外实体瘤神经母细胞瘤源于胚胎神经嵴细胞,其通常形成交感神经节和肾上腺髓质。Isobavachalcone(IBC)可作为一种有效安全的药物治疗神经母细胞瘤。
体外实验:MTT试验测定明日叶中的六种查尔酮和啤酒花中(hop)的两种查尔酮对两种人神经母细胞瘤细胞系(IMR-32和NB-39)和正常细胞(大鼠小脑颗粒细胞原代培养)的细胞毒性。所有的查尔酮对神经母细胞瘤细胞都具有细胞毒性,其中有两种查尔酮(异补骨脂查尔酮和黄当归酚H)即使高浓度(10-4 M)处理也不会影响正常细胞。蛋白印迹分析表明Isobavachalcone显著降低神经母细胞瘤细胞系caspase-3前体和caspase-9前体,随后提高裂解caspase-3和裂解caspase-9的水平。而且,Isobavachalcone处理能显著诱导Bax[1]。
体内实验:六只大鼠口服IBC(80 mg/kg)后,使用LC–MS/MS测定血浆中IBC浓度。测定平均血浆浓度-时间曲线(n=6)。血浆浓度-时间曲线(AUC)下面积1583.1 ng/mL h、平均驻留时间(MRT)5.78 h、半衰期(t1/2) 6.15 h、峰值时间(Tmax) 2.25 h、血浆清除率(CL/F) 9.86 L/h、表观分布容积(V/F) 90.34 L以及最大血浆浓度(Cmax) 351.2 ng/mL [2]。
临床试验中:目前无临床数据。
