Results and discussion

Results: P0 (first parental generation)

Effect levels (P0)

Dose descriptor:
other: Estrogen receptor binding
Basis for effect level:
other: The predicted value of log(ER-RBA) = -13.38 is far on the side of non-binding compounds on the scale of binders, weak binders and non-binders. Therefore, it can be concluded that the test substance does not bind Estrogen receptor B.

Overall reproductive toxicity

Reproductive effects observed:
not specified

Applicant's summary and conclusion

Conclusions:
The predicted value of log(ER-RBA) = -13.38 is far on the side of non-binding compounds on the scale of binders, weak binders and non-binders. Therefore it can be concluded that the test substance does not bind Estrogen receptor B.
Executive summary:

The predicted value of log(ER-RBA) = -13.38 is far on the side of non-binding compounds on the scale of binders, weak binders and non-binders. Therefore it can be concluded that the test substance does not bind Estrogen receptor B.
