生物活性

产品描述 Gemcitabine是核酸合成抑制剂,是有效、特异的脱氧胞苷类似物,用于化疗。Gemcitabine可诱导有效的p53依赖的凋亡。
体外研究

在CCRF-CEM人白血病细胞培养物中,Gemcitabine抑制50%的细胞生长,IC50为1 纳克/毫升。Gemcitabine和deoxycytidine联用使生物活性降低1000倍。[1]

在人胰腺癌L3.6pl细胞中,Gemcitabine和C225联用产生额外的细胞毒作用,并随Gemcitabine浓度增多而增强。[2]

在野生型A2780和耐顺铂ADDP细胞中,Gemcitabine和Cisplatin联用产生协同效应。 [3]

体内研究

在胰腺L3.6pl肿瘤转移的裸鼠中,Gemcitabine和C225联用导致生长抑制,肿瘤消退。Gemcitabine单独给药治疗减少了平均肿瘤体积,从538到152毫米。在Gemcitabine治疗的肿瘤中,Gemcitabine可以减少血管内皮生长因子和白细胞介素8的产生。[2]

Gemcitabine是能够显著地和特异地减少骨髓抑制性细胞的数量,并不显著改变CD4(+)T细胞,CD8(+)T细胞,NK细胞,巨噬细胞,或B细胞的数量。[4]

Gemcitabine和curcumin联用显著减少肿瘤体积(与对照组和单独Gemcitabine处理相比),Ki-67的增殖指数(与对照组相比),NF-κB的激活和表达NF-κB的调节基因产物(细胞周期蛋白D1,c-myc的和Bcl-2和Bcl-xL的细胞凋亡蛋白-1,环氧化酶-2,基质金属蛋白酶,和血管内皮生长因子的细胞抑制剂)。Gemcitabine和curcumin联用也抑制血管生成,以CD31(+)的微血管密度为标志。[5]
