Edilirdin

Edilirdin is a fictional chemical compound widely used in educational materials to illustrate concepts in medicinal chemistry, pharmacology, and drug design. It does not correspond to a real therapeutic agent, and it has no approved medical use.

In typical classroom depictions, edilirdin is a small organic molecule with a heteroaromatic core and several substituents, such as a tertiary amine and a polar functional group. Diagrams may vary, but the examples commonly emphasize features like moderate lipophilicity, potential hydrogen-bond donors and acceptors, and a molecular size suitable for oral administration in teaching contexts. These attributes are used to discuss Lipinski's rule of five, permeability, and basic pharmacokinetic concepts.

Educational uses include illustrating structure–activity relationships, synthetic planning, and ADME modeling. Students work with edilirdin in problem sets that cover retrosynthetic analysis, metabolic oxidation or hydrolysis pathways, and in silico properties prediction. The compound is often used alongside real-world examples to contrast hypothetical properties with those of established drugs.

Origin and naming: edilirdin is a constructed term created for pedagogical purposes and does not reflect a discovery or a registered substance. It appears in textbooks and online tutorials as a generic, nonhazardous placeholder compound intended to facilitate safe, neutral discussion of chemical principles.
