Description of key information
The test substance is considered to be a skin sensitizer. From an occupational point of view sensitization and possible hypersensitivity reactions can occur at inhalation and dermal exposure. Furthermore it is generally accepted that especially relatively high peak concentrations can induce sensitization, and that prevention of such concentrations will prevent workers from developing respiratory allergy.
A history of a previous hypersensitivity reaction to any of the penicillins is a contraindication for the use of Penicillin V.

- Test item: Pen V Potassium
CAS No.:132-98-9
Lot No.: B519322

Purity:99.0 %
Storage: Room temperature, protected from light
Molecular mass:388.48 g/mol - Details on the study design:
- The test item was formulated in a non-GLP trial forming as follows: the solubility of the test item was evaluated at the concentration of 100 mM. Acetonitrile did not dissolve the test item, it sank to the bottom of the test tube even after vortexing. Therefore, the test item was tried to be dissolved in ultrapure water and a homogenous, clear and transparent solution was formed after about 3 minutes of vortexing at 100 mM. The formulation with ultrapure water was tried to be mixed with the buffers of the test system (phosphate and acetate buffer) in a ratio corresponding to the reaction sample assembly in order to observe the compatibility of the formulation with the buffers of the test system. No precipitate was observed in any cases, homogenous solutions were gained. Since ultrapure water is the preferred vehicle after acetonitrile according to the guideline and the formulation complied with all obligations of the test guideline, it was chosen as the appropriate vehicle for the study and solubility in other vehicles was not evaluated. The pre-experiments on solubility of the test item was not performed in compliance with the GLP-Regulations and is excluded from the Statement of Compliance in the final report, but the raw data of these tests will be archived under the study code of present study.
The reactivity of a test chemical and synthetic Cysteine or Lysine containing peptides is evaluated by combining the test chemical with a solution of the peptide and monitoring the remaining concentration of the peptide following 24 hours of interaction time at room temperature. The peptide is a custom material containing phenylalanine to aid the detection and either Cysteine (“C”) or Lysine (“K”) as the reactive center. Relative concentrations of the peptides following the 24 hour incubation are determined by high performance liquid chromatography with gradient elution and UV detection at 220 nm. Reaction samples, reference controls A, B and C, co-elution controls and positive controls are prepared and analysed in triplicates in batches of up to 26 chemicals (including controls).

- Executive summary:
In the course of this study the skin sensitization potential of the test item “Pen V Potassium” was studied using the Direct Peptide Reactivity Assay (DPRA). For the test chemical and positive control substance, in order to derive a prediction two independent tests were conducted, one with cysteine and lysine peptides each. The results of the two valid runs were used for the classification of the test item.Peptide depletion resulted from the positive control cinnamaldehyde was 70.67 % ± 0.09 % with cysteine peptide and 52.39 % ± 0.15 % with the lysine peptide. The mean back-calculated peptide concentrations of the reference control replicates were within the expected molarity concentration range for the cysteine (0.48 – 0.51 mM) and lysine peptides (0.49 mM – 0.50 mM) and the CV % for the for the nine reference controls B and C in acetonitrile were 2.7 % and 0.4 % percentages for the cysteine and lysine peptides. For each peptide, all validity criteria were met, confirming the validity of the assay.The percent cysteine peptide depletion value of the test item was 4.94 % ± 3.83 % while the percent lysine peptide depletion was 15.11 % ± 0.48 %. The mean depletion value of the peptides was used to categorize the test chemical in one of the four classes of reactivity. No co-elution was observed with either cysteine or lysine peptides; therefore the cysteine 1:10 / lysine 1:50 prediction model was used for the discrimination between sensitizers and non-sensitizers. The mean peptide depletion of the test item was 10.03 %, which exceeded the 6.38 % threshold of the applicable prediction model and fell into the low reactivity class.
