Description

YS-201 is a dihydropyridine-type calcium channel antagonist. YS-201 has the potential for angina pectoris and hypertension treatment.

In Vivo

YS-201 (Diperdipine) markedly reduces systemic vascular resistance and improves stroke index and left ventricular ejection fraction. Mean pulmonary artery and wedge pressures are slightly increased as a possible consequence of enhanced venous return, whereas right atrial and left ventricular end-diastolic pressures are not significantly changed. Nevertheless, an increase in preload is clearly indicated by an augmented left ventricular end-diastolic volume index after administration of diperdipine[1]. After intravenous and oral doses, absolute bioavailability is calculated to be 18.7%. Biliaryexcretion accounts for about 0.1% of the total clearance of diperdipine and does not contribute to the overall elimination of the drug. After intraportal administration, the bioavailable fraction of diperdipine is increasing up to 44.3% suggesting a prehepatic site of loss of the drug[2]. The single application of diperdipine to mice and rats by gavage causes intolerance reactions starting at the lowest tested dose level of 200 mg/kg b.w. p.o. (mice) and at 250 mg/kg b.w. p.o. (rats). In the rat, toxic effects occur from 15 mg diperdipine/kg b.w./day p.o. onwards[3].

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 (5.46 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL.

    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% Corn Oil

    Solubility: 2.5 mg/mL (5.46 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL. 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.
