Developmental toxicity / teratogenicity
Administrative data
- Endpoint:
- developmental toxicity
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: This is a validated SAR model where the substance falls within the applicability domain of the model, as provided in the attached documentation. The results are adequate for the purpose of classification and labeling, and for risk assessment.
- Justification for type of information:
- QSAR prediction: migrated from IUCLID 5.6

Materials and methods
Test guideline
- Guideline:
- other: Qualitative SAR prediction
- Principles of method if other than guideline:
- The cat-SAR structure-activity relationship (SAR) program estimates the toxicological properties of chemicals based on information from previously tested compounds and the method has been described in detail in several peer-reviewed publications. The models are built for specific toxicological endpoints and describe chemical substructures that differentiate between active and inactive chemicals for the endpoint of interests (e.g., carcinogens and noncarcinogens). The cat-SAR approach is a qualitative SAR method. Chemicals in the model’s learning set are classified as positive or negative (rather than units of potency). The metric of activity is used to determine the classification based on a defined Cut-Point value that separates positive from negative prediction. The model’s sensitivity, specificity, and concordance are used to judge the likelihood that a prediction is accurate.

- other: SAR prediction
- Effect level:
- 0.05 other: predicted value of model
- Based on:
- other: categorization as active vs inactive.
- Basis for effect level:
- other: developmental toxicity
Results (fetuses)
- Details on embryotoxic / teratogenic effects:
- Embryotoxic / teratogenic effects:no effects. Remark: Death, growth retardation, functional and structural abnormalities were examined in the model.
Details on embryotoxic / teratogenic effects:
Embryotoxic/teratogenic effects included in the model:
Data on developmental toxicity included death, growth retardation, functional and structural abnormalities. These were derived from the US FDA guidelines as described by Ghanooni, M, et al., (1997, Structural determinants associated with risk of human developmental toxicity. American Journal of Obstetrics and Gynecology 176, 799-806).
Fetal abnormalities
- Abnormalities:
- not specified
Overall developmental toxicity
- Developmental effects observed:
- not specified
Any other information on results incl. tables
Predicted value (model results): 0.05 (based on 16 fragments present in the test material). Value needed to qualify as a developmental toxicant (Cut-point to separate activity categories) = 0.61. As the predicted values fall well short of the cut-point, the predicted category the test material = Non Developmental Toxicant .
Applicant's summary and conclusion
- Conclusions:
- 2-Vinylpyridine was investigated in a validated SAR model for activity involving developmental reproductive toxicity (teratogenesis). This substance is similar to compounds which were not active. Thus, 2-vinylpyridine is concluded not to be a developmental toxicant.
