项目摘要

We have been developing nucleoside antimetabolites CNDAC and ECyd as new types of antitumor agents. After incorporation of CNDAC in DNA-strands, strand-breaks were induced. In order to repair the breaks, G2-check point was activated. Therefore, it is important to develop its abrogators for combination therapy. We designed a new Chk1 inhibitor, PGED (IC50=2.8nM), which has combination effects with SN-38. ECyd is a potent inhibitor of RNA polymerase after its conversion to the corresponding 5'-triphosphate. In combination treatment with X-ray irradiation and ECyd, antitumor effects towards colon 26 tumors in vivo were effectively enhanced, due to inhibition of expression of antiapoptotic protein such as survivin. We also found that by increasing the length of the bridging linker, the PU3 (an Hsp90 inhibitor) dimmers became more cytotoxic against human breast cancer cell lines.
我们一直在开发核苷类抗代谢物CNDAC和ECyd作为新型抗肿瘤药物。在DNA链中掺入CNDAC后,诱导链断裂。为了修复断裂,G2检查点被激活。因此,开发其消除剂用于联合治疗具有重要意义。我们设计了一种新的Chk 1抑制剂PGED(IC 50 =2.8nM),它与SN-38具有联合作用。ECyd是RNA聚合酶转化为相应的5 '-三磷酸后的有效抑制剂。X射线照射与ECyd联合治疗,由于抑制抗凋亡蛋白如survivin的表达,有效地增强了对结肠26肿瘤的体内抗肿瘤作用。我们还发现,通过增加桥接接头的长度,PU 3(Hsp 90抑制剂)二聚体对人乳腺癌细胞系的细胞毒性变得更强。
