| 体外研究活性 | PCI-24781针对于多种肿瘤细胞系具有有效的抗肿瘤活性，GI50分布于0.15 μM 到3.09 μM之间。PCI-24781也抑制HUVEC 内皮细胞的增值，GI50为0.43 μM。PCI-24781处理导致HCT116 和 DLD-1细胞系中组蛋白乙酰化和微管蛋白乙酰化的剂量依赖性积累，同时诱导p21表达，PARP的剪切以及γH2AX的累积[1]。PCI-24781抑制HDACs酶活导致HR 相关基因的转录水平出现明显下降，其中包括RAD51。与抑制HR 一致，在CHO细胞中，PCI-24781处理后导致I-SceI诱导染色质断裂引起的同源定向修复能力下降[2]。PCI-24781诱发S 期缺失，G2期细胞周期停滞以及软组织（STS）细胞的凋亡。PCI-24781诱导STS细胞中Rad51 的转录抑制很有可能是通过增强E2F1在Rad51近端启动子区域的结合[3]。PCI-24781也诱导Hodgkin淋巴瘤和非霍奇金淋巴瘤中蛋白酶和活性氧依赖的NF-κB信号通路介导的细胞凋亡过程[4]。 | |||

实验计算
动物体内配方计算器（澄清溶液）
第一步：请输入基本实验信息（考虑到实验过程中的损耗，建议多配一只动物的药量）
第二步：请输入动物体内配方组成（配方适用于不溶于水的药物；不同批次药物配方比例不同，请联系Selleck为您提供正确的澄清溶液配方）
计算结果：
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于μL DMSO溶液（母液浓度mg/mL，注：如该浓度超过该批次药物DMSO溶解度，请先联系Selleck）；
体内配方配制方法：取μL DMSO母液，加入μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入μL ddH2O，混匀澄清。
体内配方配制方法：取μL DMSO母液，加入μL Corn oil，混匀澄清。
注意：1. 首先保证母液是澄清的；
2.一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
