Description

Raltitrexed is an antimetabolite agent used in chemotherapy, acting by inhibiting thymidylate synthase.

In Vitro

Raltitrexed inhibits HepG2 proliferation by arresting the cell cycle at G0/G1, and the cell cycle is mediated via downregulation of cyclin A and CDK2[1]. Raltitrexed (0.1, 0.5, 2.5 μg/mL) decreases the viability of SGC7901 cells in a dose- and time-dependent manner. Raltitrexed (0.5 μg/mL) shows typical apoptotic morphology, including nuclear shrinkage, fragmentation, chromatin condensation and apoptotic bodies in SGC7901 cells. Raltitrexed blocks the cell cycle at the G0/G1 phase, decreases in the mitochondrial membrane potential. Raltitrexed also increases the level of ROS, induces caspase-3-dependent apoptosis via activation of the mitochondria, and increases TS protein and mRNA expression levels[3]. Raltitrexed (1.5 nM) reduces the number of GM00637 cells, selectively induces gene conversions, but does not affect DSB-induced HR or NHEJ[4].

In Vivo

Raltitrexed (0, 5, 10, 11.5, 13.5, 15 mg/kg b/w, i.p.) increases the rates of resorbed embryos and growth retardation of murine model of NTDs in a dose dependent manner. Raltitrexed (11.5 mg/kg b/w) maximally inhibits the thymidylate synthase (TS) activity in embryonic tissue, decreases dTMP levels and while increases dUMP levels[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (5.45 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (4.54 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Cell Assay
[4]

To assess the effect of Raltitrexed on cell viability and/or growth, GM00637 cells are plated into 25 cm2 flasks at a density of 3.3×105 cells per flask. Twenty four hours later, the medium is replaced with medium supplemented with various doses of Raltitrexed over a broad range of concentrations ranging from less than 1 nM to greater than 1 µM. Three flasks of cells are used for each dose tested. Cells are exposed to Raltitrexed for 24 hours, at which time the cells are refed with medium containing no Raltitrexed. Forty-eight hours after feeding with drug-free medium, cells are harvested and counted. The cell counts for the cells exposed to the various Raltitrexed doses are compared with the cell count for control cells not exposed to Raltitrexed as a measure of the impact of Raltitrexed on cell viability and/or growth rate.

Animal Administration
[2]

The adult (7-8 week, 19-20 g) C57BL/6 mice are used in the experiment. Mice are maintained under 22°C with a 12 h light/day cycle and fed with standard mouse chow and tap water ad libitum. Female mice are mated with male overnight and vaginal plugs are examined in the following morning. The presence of vaginal plug in the pregnant mice is considered as gestational day 0.5. Pregnant mice are randomly divided into 6 groups with 10 mice in each group. Raltitrexed is dissolved in 0.9 % NaCl, and five groups are intraperitoneally injected with different doses of Raltitrexed (5, 10, 11.5, 13.5, 15 mg/kg b/w) on gestational day 7.5. The control group is intraperitoneally injected with 0.9 % NaCl at the same volume on gestational day 7.5. On gestational day 11.5, pregnant mice are sacrificed, and embryos are examined under dissect microscope.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
