Description

Plitidepsin (Aplidine) is a potent anti-cancer agent by targeting eEF1A2 ( KD=80 nM)[1]. Plitidepsin possesses antiviral activity and is against SARS-CoV-2 with an IC90 of 0.88 nM. Plitidepsin is usually used for multiple myeloma and advanced cancer research, and has the potential for COVID-19 research[1][2].

In Vitro

Plitidepsin (20 nM; 1 h) induces a dose-dependent decrease in VEGF secretion in MOLT-4 cells[1].
? Plitidepsin (20 nM; 1 h) does not result in significant inhibition of VEGF-R1 mRNA in normal endothelial cells, which do express VEGFR-1 but do not secrete VEGF[1].
? Plitidepsin inhibits SARS-CoV-2 with an IC90?of 1.76 nM. In hACE2-293T cells, Plitidepsin exhibits anti–SARS-CoV-2 activity with an IC90 of 0.88 nM. In an established model of human pneumocyte-like cells, Plitidepsin inhibits SARS-CoV-2 replication with an IC90?of 3.14 nM and a selectivity index of 40.4[1].

In Vivo

Plitidepsin (intraperitoneal?injection; 0.3 mg/kg or 1 mg/kg; 2 hours before infection with SARS-CoV-2) significantly reduces SARS-CoV-2 infection in BALB/c mice expressing human ACE2. 0.3 mg/kg plitidepsin group results in a reduction of nearly 2 log units in SARS-CoV-2 viral titers in the lungs, and the 1 mg/kg group leads to? a reduction of 1.5 log units relative to the vehicle control group[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 (2.25 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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 (2.25 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.
