NUMBER OF CELLS EVALUATED: 400000 cells per flask
DETERMINATION OF CYTOTOXICITY: Method: relative growth - Evaluation criteria:
- A test is considered to be negative if there is no biologically relevant increase in the number of mutants.
There are several criteria for determining a positive result:
-a reproducible three times higher mutation frequency than the solvent control for at least one of the concentrations;
-a concentration related increase of the mutation frequency; such an evaluation may be considered also in the case that a three-fold increase of
the mutant frequency is not observed;
-if there is by chance a low spontaneous mutation rate in the corresponding negative and solvent controls a concentration related increase of the mutations within their range has to be discussed.

In conclusion, in the described mutagenicity test under the experimental conditions reported, the test item HOSTACERIN DGI is considered to be non-mutagenic in the HPRT locus using V79 cells of the Chinese Hamster. - Executive summary:
In a mammalian cell gene mutation assay (HPRT locus),V79cells culturedin vitrowere exposed to HOSTACERIN DGIsuspended in cell culture medium (MEM)at concentrations of
- 0.316, 1.00, 3.16, 10.0, 31.6, 100, 316, 1000, 2500 and 5000 µg/mL (without metabolic activation, Experiment I)
- 0.316, 1.00, 3.16, 10.0, 31.6, 100, 316, 1000, 2500 and 5000 µg/mL (with metabolic activation, Experiment I)
- 0.316, 1.00, 3.16, 10.0, 31.6, 100, 316, 1000, 2500 and 5000 µg/mL (without metabolic activation, Experiment II)
- 25, 50, 100, 250, 500, 750, 1250, 2000, 3000 and 5000 µg/mL (with metabolic activation, Experiment II).
HOSTACERIN DGI was tested up to cytotoxic concentrations.
No biologically relevant growth inhibition was observed in experiment I without metabolic activation and in experiment II with metabolic activation.
A biologically relevant growth inhibition was observed in experiment I with metabolic activation and in experiment II without metabolic activation.
In experiment I without metabolic activation the relative growth was 115.5% for the highest concentration (5000 µg/mL) evaluated. The highest biologically relevant concentration evaluated with metabolic activation was 5000 µg/mL with a relative growth of 68.4%. In experiment II without metabolic activation the relative growth was 54.7% for the highest concentration (5000 µg/mL) evaluated. The highest concentration evaluated with metabolic activation was 5000 µg/mL with a relative growth of 83.6%.
In experiment I without metabolic activation the highest mutation rate (compared to the negative control values) of 1.88 was found at a concentration of 2500 µg/mL with a relative growth of 100.7%.
In experiment I with metabolic activation the highest mutation rate (compared to the negative control values) of 2.77 was found at a concentration of 2500 µg/mL with a relative growth of 65.3%.
In experiment II without metabolic activation the highest mutation rate (compared to the negative control values) of 1.20 was found at a concentration of 10 µg/mL with a relative growth of 98.5%.
In experiment II with metabolic activation the highest mutation rate (compared to the negative control values) of 1.14 was found at a concentration of 2000 µg/mL with a relative growth of 88.5%.In both experiments no biologically relevant increase of mutants was found after treatment with the test item (with and without metabolic activation), No dose-response relationship was observed.
The positive controls did induce the appropriate response.
There was no evidence of a concentration related positive response of induced mutant colonies over background.
This study is classified as acceptable. This study satisfies the requirement for Test Guideline OPPTS 870.5300, OECD 476 for in vitro mutagenicity (mammalian forward gene mutation) data.
