Ara-G 是一种脱氧鸟苷 (GdR) 类似物和核苷类似物,可被 T 淋巴谱系细胞迅速转化为其相应的阿拉伯糖基鸟嘌呤核苷酸三磷酸 (araGTP),从而抑制 DNA 合成和对 T 淋巴母细胞的选择性体外毒性细胞系以及来自 T 细胞急性淋巴细胞白血病 (ALL) 患者的新鲜分离的白血病细胞。
产品描述 | Ara-G is a deoxyguanosine (GdR) analog and a nucleoside analogue that is rapidly converted by cells of the T lymphoid lineage to its corresponding arabinosylguanine nucleotide triphosphate (araGTP), resulting in inhibition of DNA synthesis and selective in vitro toxicity to T lymphoblastoid cell lines as well as to freshly isolated leukemia cells from patients with T cell acute lymphoblastic leukemia (ALL). |
体外活性 | Ara-G induced an S-phase arrest in both Raji and ML-1. Within 3 hours of Ara-G treatment, the levels of soluble Fas ligand (sFasL) in the medium increased significantly in CEM cultures. Pretreatment of CEM cells with a Fas antagonistic antibody inhibited ara-G-mediated cell death[3]. |
体内活性 | Intravenous injection of 10(6) 6C3HED cells resulted in 100 percent mortality within 18 days, with autopsy revealing tumor infiltration of multiple organs. Evidence of araG's ability to purge bone marrow of malignant tumor cells without causing significant toxicity to normal marrow-derived hematopoietic progenitor cells was documented in experiments in which 75 percent of lethally irradiated mice receiving transplants of syngeneic bone marrow contaminated with 6C3HED tumor cells and treated ex vivo with 100 mM araG for 18 hours survived for 250 to > 400 days. Reconstitution of the lymphoid, myeloid, and erythroid lineages with donor cells in surviving mice was documented. The data presented indicate that araG may effectively purge bone marrow of malignant T cells without irreversible toxicity to hematopoietic stem cells[1]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
