Background | Nutlin 3a, the active isoform of Nutlin-3, is an MDM2 antagonist that inhibits the MDM2-p53 interaction and stabilizes p53 protein, thereby inducing cell cycle arrest and apoptosis. |
Biological Activity | Nutlin-3a 是 Nutlin-3 的活性异构体,为一种鼠双微体 2 (MDM2) 拮抗剂,抑制 MDM2-p53 相互作用,且稳定 p53 蛋白,因此诱导细胞周期停滞和细胞凋亡[1-3]。 |
In Vitro | Nutlin-3a是Nutlin-3的活性对映体。 Nutlin-3a是一种高选择性MDM2拮抗剂和p53诱导剂。与10μMNutlin3a一起温育7天导致NIH/3T3细胞生长> 90%的抑制,但不影响MEF的增殖,其中药物的两个靶标都被消除。 Nutlin-3a有效地抑制所有细胞系中的细胞周期进展,使S期隔室耗尽至0.2-2%并增加G1期和G2期/ M期隔室,表明G1和G2停滞。 p53靶点p21和MDM2在Nutlin 3a加入后3小时显著升高,并在8小时达到最大水平。 Nutlin-3a在40小时后诱导约60%的SJSA-1和MHM细胞凋亡,60小时后分别增加(分别为85%和65%)[2]。Nutlin-3a是一种抑制MDM2,激活野生型p53并诱导细胞凋亡的治疗剂,作为TP53野生型卵巢癌的治疗化合物。具有野生型TP53的三种细胞系(HOC-7,OVCA429和A2780)对Nutlin 3a高度敏感(IC 50 = 4至6μM)。 SKOV3细胞对Nutlin 3a的IC50为38μM。两种具有TP53野生型的卵巢透明细胞系(TOV21G和OVAS)对Nutlin 3a的生长抑制(IC50分别为14和25μm)相对于TP53突变细胞系相对更敏感[1]。 |
In Vivo | Nutlin-3a在所有模型中均有效,平均肿瘤生长抑制≥98%。 Nutlin-3a以剂量依赖性方式抑制异种移植物生长,最高剂量(200mg/kg)显示出显著的肿瘤缩小(8个部分和1个完全消退)。已建立的SJSA-1和MHM骨肉瘤异种移植物与Nutlin-3a引起广泛的肿瘤消退[2]。 |
Cell Experiment | 将所有15个细胞系以每孔1×10 3个细胞的密度接种在96孔板中。 24小时后,更换培养基并用递增浓度的Nutlin-3a(1μM,5μM,10μM,25μM,50μM和70μM)处理细胞。温育72小时后,向各孔中加入WST-1,以450nm的吸光度使用酶标仪,测定残留的活细胞数。根据需要用较小滴定的Nutlin-3a重复实验以确定细胞系的精确IC 50。 IC50已定义。再次以与上述相同的方式铺板细胞系,并用各自的IC50用Nutlin-3a处理,并在24,48和72h加入WST-1细胞活力测量[1]。 |
Animal Experiment | 小鼠[2]携带sc肿瘤异种移植物的裸鼠(在SJSA-1,LnCaP和22Rv1研究中每组10只小鼠,在MHM研究中每组15只小鼠)每天口服给予Nutlin-3a两次(50-200mg/kg)或载体(1%Klucel,0.1%吐温80),持续2周(22Rv1和LnCap)或3周(SJSA-1和MHM)。用卡尺测量肿瘤体积并计算。对于Western印迹分析,具有已建立的SJSA-1肿瘤的裸鼠(200-400mm 3,每组三只动物用三剂量的Nutlin-3a以150mg/kg(0,8和24小时)处理,并且肿瘤是在最后一次剂量后3小时收获。肿瘤样品快速冷冻并加工[2]。 |
