Background |
Carboplatin is a DNA synthesis inhibitor that binds to DNA, inhibits replication and transcription and induces cell death. It is a derivative of cisplatin. |
Biological Activity |
Carboplatin (NSC 241240) 是一种 DNA 合成 抑制剂,其与 DNA 结合,抑制复制和转录并诱导细胞死亡。Carboplatin (NSC 241240) 是顺铂的衍生物,是一种有效的抗癌剂。[1-4] |
In Vitro |
卡铂是一种抗肿瘤剂,在亲核试剂和人乳腺癌MCF-7细胞胞浆提取物存在下具有增强的DNA结合活性[1]。与17-AAG相比,卡铂对人卵巢细胞如A2780,SKOV3,IGROV1和HX62的细胞毒性较低,IC50分别为6.177,12.442,2.233和116.068μM。此外,卡铂不影响HSP90或改变17-AAG的活性以抑制HSP90 [2]。卡铂降低了Brca1(IC50,3.4μM)和Brca2细胞(IC50,1.9μM)的活力。卡铂(25μM)与ABT-888结合也在BRCA1细胞中显示出凋亡作用[3]。 |
In Vivo |
卡铂(60 mg/kg,ip)对肿瘤有轻微影响,但在携带A2780人卵巢癌异种移植物的小鼠中与17-AAG联合显著抑制肿瘤生长[2]。卡铂(25mg/kg,口服)与ABT-888联合可延迟Brca2异种移植物中的肿瘤生长[3]。 |
Cell Experiment |
将指数生长的A2780细胞接种在96孔微量滴定板中。对于研究暴露于17-AAG或卡铂的序列的影响的实验,将细胞暴露于递增浓度的17-AAG或卡铂24小时。选择暴露于第一药剂24小时的时间段,使得A2780细胞暴露于第一药物至少一倍的倍增时间(18-24小时)。然后用无菌磷酸盐缓冲盐水洗涤细胞并补充培养基。此后,加入第二种药物(细胞在前24小时未暴露于其中)或培养基96小时。进行SRB测定。所有实验一式三份进行[2]。 |
Animal Experiment |
小鼠[2]通过在每个侧腹中注射4×10 6个细胞,将A2780人卵巢癌细胞系在雌性无胸腺NCr裸鼠(nu/nu)中作为皮下异种移植物生长。将具有相当于0.69mm 3的平均体积的确定肿瘤的小鼠随机分组(每组6只动物)用对照载体(43%乙醇,33%聚丙二醇和24%cremaphor用无菌水以1:7稀释)处理第1天-4,17-AAG(腹膜内80mg/kg,第1-4天),卡铂(60mg/kg IP第0天)或17-AAG(80mg/kg IP第1-4天)和卡铂(60mg/kg IP天0)。每周评估肿瘤生长三次,并根据验证的公式计算肿瘤体积:体积= 4.19×(a/4 + b/4)3,其中a是较长的b和较短的直径。然后将肿瘤体积表示为治疗开始时体积的比例(相对肿瘤体积)[2]。 |
