Description

NP213 TFA is a rapidly acting, novel, first-in-class synthetic antimicrobial peptide (AMP), has anti-fungal activities. NP213 TFA targets the fungal cytoplasmic membrane and plays it role via membrane perturbation and disruption. NP213 TFA is effective and well-tolerated in resolving nail fungal infections[1][2].

IC50 & Target

IC50: fungal[1]

In Vitro

NP213 (500-1000 μg/mL; 18 hours) increases the number of PI-stained T. rubrum NCPF0118 cells in samples. This results suggests that NP213 is fungicidal and the mechanisms of action involved membrane permeabilization[1].
NP213 is against T. rubrum NCPF0118, shows different MIC values against T. rubrum NCPF0118, and the MICs varies depending on the source of the keratin. The MIC values are 16-32 mg/L, 125 mg/L, and 250 mg/L for NP213 in 1640 media containing human nail Keratin, human skin Keratin and Lamb’s wool Keratin, respectively[1].NP213 TFA (2-3 hours; 0-8 μg/ml) has great activity against clinically relevant yeast, including candida spp, Cryptococcus spp and Trichosporon spp. For all 122 yeast isolates, with the median MIC100 values of 1-2 μg/ml[3].

Cell Cytotoxicity Assay[3]

Cell Line: Clinically relevant yeast isolates
Concentration: 0 μg/ml; 0.125 μg/ml; 0.25 μg/ml; 0.5 μg/ml; 1 μg/ml; 2 μg/ml; 4 μg/ml; 8 μg/ml
Incubation Time: 2 h, 2.5 h, 4 h
Result: Decreased isolates growth as a dose-dependent manner.
In Vivo

NP213 TFA (25 mg/kg) is well tolerated in mice. In Murine models of acute disseminated candidiasis, NP213 is tolerated and efficacious and exhibits a half-life of approximately 4.5 h[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; 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: ≥ 2.5 mg/mL; 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 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

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.
