IC50: 46 nM (Hedgehog, in Hh cell assay)[1]

体外研究 用小分子Hh抑制剂如HhAntag和天然产物Cyclopamine(均与Smo结合)治疗可诱导成神经管细胞瘤基因小鼠模型的肿瘤缓解[1]。环巴胺是一种Hedgehog(Hh)通路拮抗剂。环巴胺抑制细胞生长。环巴胺(3μM)抑制Hh通路活性和消化道肿瘤细胞系的生长与PTCHmRNA的表达相关[2]。 Cyclopamine是一种甾体生物碱,通过与Smo的直接相互作用抑制Hh信号传导[3]。
体内研究 环巴胺导致异种移植肿瘤持续消退。环巴胺治疗动物的肿瘤完全消退12天[2]。环巴胺(1.2 mg)治疗在移植入裸鼠后阻断人胰腺癌细胞的肿瘤形成[3]。
细胞实验 将细胞在96孔板中一式三份培养在测定培养基中,在0h以正文中指出的浓度加入5E1单克隆抗体,ShhNp和/或环巴胺(3μM)。使用CellTiter96比色测定,通过在490nm(OD490)在2天和4天的光密度测量来确定活细胞质量。相对生长计算为OD(第4天)-OD(第2天)/ OD(第2天)[2]。
动物实验 小鼠[3]将总共0.1mL Hanks'平衡盐溶液和含有2×106个细胞的基质胶(1:1)皮下注射到CD-1裸鼠中。使肿瘤生长4天至最小体积125mm 3;对所有受试者同时开始治疗。每天皮下注射小鼠皮下注射载体(三油酸甘油酯:乙醇4:1v / v)或环巴胺悬浮液(每小鼠1.2mg三油酸甘油酯:乙醇4:1v / v),持续7天。在治疗期结束时,从小鼠切下肿瘤,称重,然后在4℃下用4%多聚甲醛固定3小时,包埋在石蜡中并切片(6μm)。使用重组Tdt通过TUNEL鉴定凋亡细胞。然后将切片用曙红复染。从随机选择对应于两个对照和两个环巴胺处理的肿瘤的外部,中间和内部的区域的8×20-放大的视野。我们手动计算了TUNEL阳性细胞核的数量。进行苏木精/伊红染色。
