Test for Chemical Induction of Chromosome Aberration in Cultured Chinese Hamster Ovary (CHO) Cells With and Without Metabolic Activation. Test Article: N,N,N',N'-tetramethyl Ethanediamine (TMEDA)
Abstract
N,N,N',N'-tetramethyl ethanediamine (TMEDA, 99.86% pure) was tested for its potentials to induce chromosome aberrations in cultured Chinese Hamster Ovary (CHO) cells with and without metabolic activation according to OECD TG 473 in compliance with Good Laboratory Practice. TMEDA was tested at concentrations of 500, 1000, 2500 and 5000 micrograms/mL in both with and without activation. It produced a positive response in this system with or without metabolic activation, but only at the highest concentration 5,000 micrograms/mL However, according to the OECD guidelines TG 473, the compound is considered to be negative in the CHO chromosomal aberration assay, since the compound is not clastogenic at 0.01M (1,140 micrograms/mL). A confirmatory chromosome aberration assay was performed without activation also showed negative at concentrations up to 3,000 micrograms/mL but positive at the highest concentration.
