Natamycin
Based on 8 publication(s) in Google Scholar
Natamycin (Pimaricin) is a macrolide antibiotic agent produced by several Streptomyces strains. Natamycin inhibits the growth of fungi via inhibition of amino acid and glucose transport across the plasma membrane. Natamycin is a food preservative, an antifungal agent in agriculture, and is widely used for fungal keratitis research.

Natamycin, an important macrolide antibiotic, produced by several Streptomyces species, including S. natalensis, S. gilvosporeus, S. lydicus and S. chattanoogensis, can inhibit the growth of fungi via immediate inhibition of amino acid and glucose transport across the plasma membrane. Natamycin is widely used in the food industry and in pharmacotherapy for topical treatment. Unlike other polyene antibiotics, the mode of action of Natamycin is not based on the ergosterol-dependent permeabilization of the plasma membrane. The immediate cessation of growth of yeasts by Natamycin treatment indicates that there might be an instantaneous effect of Natamycin at the level of the plasma membrane[1][2].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.67 mg/mL (2.51 mM); Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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.
