 GEM-5用途


GEM-5是一种基于吉西他滨的结合物,含有HIF-1α抑制剂(YC-1)(IC50=30 nM)。GEM-5可显著下调HIF-1α的表达,上调抑癌基因p53的表达。GEM-5诱导A2780细胞凋亡并抑制肿瘤生长[1]。

IC50: 30 nM (HIF-1α) in A2780[1]

体外研究 GEM-5(0-80μM;12小时)在缺氧条件下对A2780细胞具有极好的抗肿瘤活性,IC50为0.03μM【1】。GEM-5(0.5μM;72小时)在常氧条件下使凋亡细胞数增加到52.67%,在缺氧条件下使A2780细胞的凋亡细胞数增加到80.89%[1]。GEM-5(0.5μM;24小时)将细胞周期阻滞在S期(常氧下为63.02%,缺氧下为72.64%)[1]。GEM-5(0.1和1μM;24小时)在缺氧条件下以剂量依赖性的方式降低HIF-1α的水平并增加p53的水平[1]。凋亡分析细胞系:A2780细胞【1】浓度:0.5μM孵育时间:72小时结果:在常氧条件下,凋亡细胞数增加到52.67%,在缺氧条件下,凋亡细胞数增加到80.89%。细胞周期分析细胞系:A2780细胞【1】浓度:0.5μM孵育时间:24小时结果:细胞周期阻滞于S期(常氧63.02%,缺氧72.64%)。Western Blot分析细胞系:A2780细胞【1】浓度:0.1和1μM孵育时间:24小时结果:HIF-1α水平降低,p53水平升高,呈剂量依赖性
体内研究 GEM-5(125或271 mg/kg;尾静脉注射,每周一次,共4周)有效抑制A2780异种移植小鼠模型中的肿瘤生长,并表现出低毒性[1]。动物模型:GEM-5(125或271 mg/kg;尾静脉注射,每周一次,共4周)有效抑制A2780异种移植小鼠模型中的肿瘤生长,并表现出低毒性[1]。剂量:125或271 mg/kg给药:尾静脉注射,每周1次,连续4周。结果:在A2780异种移植小鼠模型中,有效抑制肿瘤生长,毒性低。
