key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
1. SOFTWARE: QSAR Toolbox 4.5
2. MODEL (incl. version number): Androgen Receptor Antagonism (Human in vitro) - Danish QSAR
DB battery model (v.1.0)
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL: NC(CCCNC(N)=N)C(O)=O
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
- Defined endpoint: AR antagonism; Androgen Receptor Binding
5. APPLICABILITY DOMAIN: The target chemical FALLS within the applicability domain, please see
