Non-ER binder due to non-cyclic molecular structure.
Estrogen receptor (ER) binding is a molecular initiating event much like protein binding that leads to a series of adverse outcomes, which are typically considered reproductive and development hazards. It is an endpoint where several comprehensive databases exist, which has lead to the development of several approaches for using (Q)SARs to predict ER-binding and possible endocrine disruption .
Popular among these are the “four phase” assessment that includes Comparative Molecular Field Analysis (CoMFA) and the Common Reactivity Pattern Approach (COREPA)
Since the RE-binding is a receptor mediated event, particular organic functional groups, size and shape are critical to binding potency.
Sodium dodecylbenzenesulfonate have a molecular weight of less than 500, but do not possess a cyclic structure is reported to non-binders to the receptor and therefore Sodium dodecylbenzenesulfonate does not cause reproductive toxicity.
Applicant's summary and conclusion
- Conclusions:
- Non-ER binder due to non-cyclic molecular structure.Sodium dodecylbenzenesulfonate have a molecular weight of less than 500, but do not possess a cyclic structure is reported to non-binders to the receptor and therefore sodium dodecylbenzenesulfonate does not cause reproductive toxicity.
- Executive summary:
Sodium dodecylbenzenesulfonate have a molecular weight of less than 500, but do not possess a cyclic structure is reported to non-binders to the receptor and therefore sodium dodecylbenzenesulfonate does not cause reproductive toxicity.
