产品描述 | Raltitrexed (D1694)(IC50 of 9 nM), a thymidylate synthase inhibitor, is used for the inhibition of L1210 cell growth. |
靶点活性 | TS:9 nM |
体外活性 | Raltitrexed induces double-stranded DNA breaks in a concentration-dependent manner. In Lovo cells and LS174T cell lines containing wild-type p53, Raltitrexed increases the levels of the Bax protein up to 5-fold. In human colon cancer cells, Raltitrexed is actively absorbed into cells and is then rapidly and extensively metabolized into a series of polyglutamates, which results in the effective inhibition of thymidylate synthase. Raltitrexed is delivered to the brain very quickly and can be detected in all brain tissues within 5 minutes. In human colon cancer cells, the combination of Raltitrexed and SN-38 results in a synergistic cytotoxic effect within a range of concentrations. Raltitrexed is a specific folate-based inhibitor of thymidylate synthase. The effect on the activity of advanced rectal cancer is similar to fluorouracil (5-fluorouracil) plus leucovorin. Raltitrexed produces activity by rapid cell entry and glutamination. The glutaminated derivatives are more than 100 times more active than the parent compound. In the HCT-8 cell line, Raltitrexed results in an increase in intracellular phosphoribosyl pyrophosphate (PRPD) indicating that the cytotoxic effect of Raltitrexed in combination with 5-FU is due to increased nucleotide formation of 5-FU. Combinations of Raltitrexed and folinic acid (5FU-FA) show a combination of mode-dependent, synergistic inhibition of proliferation, which is determined by measuring the combination series. Raltitrexed combined with Vorinostat produced significant synergistic effects of cell cycle perturbation and S-phase arrest. |
体内活性 | Raltitrexed can be transported directly into the brain through the olfactory pathway in rats. |

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。
