Obetald

Obetald is a fictional chemical compound commonly used in pharmacology and medicinal chemistry textbooks as a placeholder to illustrate core concepts such as receptor binding, dose-response relationships, metabolism, and toxicology. The name is not associated with a real-world substance and has no entry in major chemical registries.

In educational contexts, obetald is described as a small, moderately lipophilic heterocyclic amide with a molecular formula approximated as C12H14N2O3 (fictional). Its modeled pharmacokinetic profile is typically presented as rapid absorption after oral administration, hepatic metabolism via common cytochrome P450 pathways, and elimination with a half-life of several hours, to illustrate standard concepts rather than real data. Synthesis examples in textbooks outline a generic, multi-step route from readily available reagents, stressing general lab techniques such as amide formation and ring closure rather than providing actionable instructions.

Obetald is used to demonstrate principles including competitive binding to a hypothetical receptor, the impact of structure-activity relationships, and the interpretation of concentration–response curves. It is not approved for medical use, and no clinical trial data exist. Because it is a pedagogy tool, real-world safety, dosing, and regulatory considerations are not applicable. The term also appears in case studies and problem sets to help students practice pharmacokinetic calculations and risk assessment.
