| ln Vitro |
At MIC values ranging from 0 to 100 μg/ml, pyrrolnitrin has antibiotic properties against a range of bacteria and fungi. With minimum inhibitory concentrations (MIC) of 50 μg/ml, 100 μg/ml, 0.78 μg/ml, 10 μg/ml, 12.5 μg/ml, and 1 μg/ml, respectively, it is effective against Staphylococcus aureus, Mycobacterium, Bacillus subtillis, Candida albicans, Aspergillus niger, and Trichophyton rubrum1. A microtitre plate experiment demonstrates the antibacterial effect of pyrrolnitrin (0-100 μg/ml). With MIC of 6.25 μg/ml, it is effective against Bacillus subtilis ATCC 6051, Bacillus licheniformis ATCC 14580, Bacillus coagulans ATCC 7050, and Bacillus thuringiensis ATCC 10792.
Pyrrolnitrin exhibits potent antifungal activity against various fungal pathogens. It is active against isolates of the fungi C. albicans, C. neoformans, and B. dermatitidis. The compound is effective mainly against Trichophyton, Microsporium, Epidermophyton, and Penicillium. |
| ln Vivo |
No detailed in vivo activity data in animal models has been reported for Pyrrolnitrin. It is primarily used as an agricultural fungicide. Its antifungal activity has been demonstrated in plant and crop protection applications.
|
| Enzyme Assay |
Antifungal susceptibility testing: Pyrrolnitrin is tested against various fungal strains using broth microdilution or agar diffusion methods according to CLSI guidelines. Minimum inhibitory concentrations (MICs) are determined after incubation at appropriate temperatures for the test organisms.
|
| Cell Assay |
Antifungal activity is evaluated using standard broth microdilution assays against fungal strains including Trichophyton, Microsporium, Epidermophyton, Penicillium, Candida albicans, and Cryptococcus neoformans. MICs are determined after incubation.
|
| Animal Protocol |
Animal models of fungal infection could be used to evaluate Pyrrolnitrin in vivo. However, it is primarily used in agricultural applications rather than as a therapeutic agent for human fungal infections.
|
| ADME/Pharmacokinetics |
Pyrrolnitrin has a molecular formula of C10H₆Cl2N2O2 and a molecular weight of 257.07. It appears as pale yellow crystals with a melting point of 124.5degC. It gradually changes to a red or brown color on exposure to sunlight and loses antibiotic activity.
|
| Toxicity/Toxicokinetics |
No detailed toxicity data has been published for Pyrrolnitrin in mammalian systems. As an agricultural fungicide, it is not intended for human therapeutic use.

| Additional Infomation |
Pyrrolidone is a pyrrole compound with a chlorine atom at position 3 and a 3-chloro-2-nitrophenyl substituent at position 4. It is both a bacterial metabolite and an antifungal drug. It belongs to the pyrrole class, monochlorobenzene class, C-nitro compounds, and alkaloids. Pyrrolidone has been reported to exist in Pseudomonas, Burkholderia cepacia, and other microorganisms for which relevant data exist. Pyrrolidone is a pyrrole antifungal agent isolated from various Pseudomonas genera. Pyrrolidone interferes with terminal electron transport systems and inhibits cellular respiration. This compound is active against dermatophytes, especially Trichophyton. 3-Chloro-4-(3-chloro-2-nitrophenyl)pyrrole. An antifungal antibiotic isolated from Pseudomonas pyrrole. It is mainly effective against Trichophyton, Microsporum, Epidermophyton, and Penicillium.
Pyrrolnitrin is a pyrrole antifungal antibiotic isolated from Pseudomonas species. It exhibits potent antifungal activity against Trichophyton, Microsporium, Epidermophyton, and Penicillium. It is widely used in agriculture to control fungal pathogens. The compound is for research use only. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (9.72 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), Clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of DMSO stock solution (25.0 mg/mL) to 400 μL of PEG300 and mix well; then add 50 μL of Tween-80 and mix well; finally add 450 μL of physiological saline and adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (9.72 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), Clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of DMSO stock solution (25.0 mg/mL) to 900 μL of 20% SBE-β-CD saline and mix well. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.5 mg/mL (9.72 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), Clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of DMSO stock solution (25.0 mg/mL) to 900 μL of corn oil and mix well.  (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
