Molarity Calculator

Tegaserod maleate (SDZ-HTF-919) is an orally active serotonin receptor 4 (HTR4; 5-HT4R) agonist and a 5-HT2B receptor antagonist. Tegaserod maleate has pKis of 7.5, 8.4 and 7.0 for human recombinant 5-HT2A, 5-HT2B and 5-HT2C receptors, respectively. Tegaserod maleate causes tumor cell apoptosis, blunts PI3K/Akt/mTOR signaling and decreases S6 phosphorylation. Tegaserod maleate has anti-tumor activity and has the potential for irritable bowel syndrome (IBS) research.

In Vivo

Tegaserod maleate (SDZ-HTF-919; 5 mg/kg/day; ip; for five consecutive days) delays tumor growth, reduces metastases, increases survival and suppresses p-S6 in vivo[1].
Tegaserod maleate (0.1-2.0 mg/kg; IP 15 min prior to gastric loading) significantly accelerates the gastric emptying rate of glucose in db/db mice, reducing the fraction of the meal remaining in the stomach at 30 min by 80% with 0.1mg/kg[2].

Animal Model: C57BL/6 J mice were subcutaneously injected with B16F10 cells[1]
Dosage: 5 mg/kg
Administration: Administered intraperitoneally (i.p.) daily for five consecutive days
Result: Treatment significantly decreased tumor growth and resulted in only slight decreases in weight following treatment.
Animal Model: Female C57BLKS/J db/db mice[2]
Dosage: 0.1, 0.5, 1.0, 2.0 mg/kg
Administration: IP; 15 min prior to gastric loading
Result: Produced a dramatic decrease in the fraction of the meal remaining in the stomach for doses as low as 0.1 mg/kg (0.1 mg/kg).
Accelerated gastric emptying, with a reduction of nearly 80% in the fraction remaining at 30 min (P < 0.0001) (0.1 mg/kg).
Induced a significant decrease in the gastric emptying rate as the amount of the meal remaining at 30 min was significantly greater (2.0 mg/kg).
Resulted in inhibition of tegaserod-induced increased gastric emptying (0.1 mg/kg).

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

    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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.99 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
