Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information):
positive clastogenic in the presence and in the absence of metabolic activation

FR-513 was found to be clastogenic in the presence of metabolic activation and at the highest test substance concentration (1000 microgram/ml) in the absence of metabolic activation. FR-513 has the potential to disturb mitotic processes and cell cycle progression.
Executive summary:

Evaluation of the ability of FR-513 to induce chromosome aberrations in cultured peripheral human lymphocytes was conducted using appropriate guidelines such as OECD 473. The report describes the effect of FR-513 on the number of chromosome aberrations in cultures perpheral human lymphocytes in the presence and absence of a metabolic activation system. A range finder study was conducted which followed by several main tests.

It is concluded that the test was valid and under the experimental conditions FR-513 was found to be clastogenic in the presence of metabolic activation and at the highest test substance concentration (1000 microgram/ml) in the absence of metabolic activation. FR-513 has the potential to disturb mitotic processes and cell cycle progression.
