一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Zosuquidar是一种新型有效的P-糖蛋白调节剂[1]。P-糖蛋白(P-gp)在脑、肝脏、小肠和肿瘤细胞中表达。在肿瘤细胞中,P-糖蛋白(P-gp)作为外排泵发挥功能,负责多药耐药性。肿瘤中P-糖蛋白(Pgp)过表达导致对结构上不相关的溶瘤剂的多药耐药性(MDR)[2]。
体外实验:在CEM/VLB100细胞中,LY335979(0.1 μM)完全恢复细胞对vinblastine、doxorubicin (Dox)、etoposide和Taxol的敏感性。在CEM/VLB100质膜中,LY335979阻断[3H]叠氮基光亲和标记M(r)约170,000的 Pgp,并竞争性抑制[3H]vinblastine与Pgp的结合平衡,Ki值约为0.06 μM[3]。在所有表达P-gp的白血病细胞系中,包括K562/HHT40、K562/HHT90、K562/DOX和HL60/DNR中,Zosuquidar完全或部分恢复药物敏感性。在具有活性P-gp的原代AML母细胞中,Zosuquidar增强anthracyclines (daunorubicin、idarubicin、mitoxantrone)和 gemtuzumab ozogamicin (Mylotarg)的细胞毒性[4]。
在体实验:在携带P388/ADR鼠白血病细胞的小鼠中,LY335979与Dox或etoposide组合治疗显著延长小鼠寿命,药代动力学没有明显改变。在MDR人非小细胞肺癌裸鼠异种移植模型中,LY335979增强Taxol的抗肿瘤活性[3]。
临床试验:在未治疗的非霍奇金淋巴瘤患者中,进行I/II期临床试验研究zosuquidar的安全性和耐受性。在口服三个500 mg剂量的zosuquidar与CHOX组合给药,药物毒性最小,并且没有观察到CHOP相关毒性的增强[5]。在I期研究的晚期实体瘤患者中,zosuquidar(100-300 mg/m2)可以抑制vinorelbine的清除率至适度程度[6]。
