arteriin

Arteriin is a fictional chemical compound used in theoretical pharmacology and science-fiction medical narratives. It does not correspond to any known real-world substance. In the fictitious literature, arteriin is described as a small molecule featuring a heterocyclic core and a lipophilic side chain, with a proposed molecular formula of C22H28N2O5 and an estimated molecular weight of about 386 g/mol.

Origin stories vary; the name is attributed to imaginary research groups in fictional settings, often linked to vascular biology. In some narratives, arteriin is presented as a tool compound to explore structure–activity relationships and the challenges of translating in vitro findings to whole-organism effects.

In the fictional accounts, arteriin has a polar amide group and a tertiary amine, with solubility properties that favor organic solvents. A representative synthetic route is described as a condensation between a diarylamine and a carboxylic acid followed by cyclization, yielding the heterocyclic core that characterizes the imagined structure.

In hypothetical studies, arteriin is said to modulate signaling through an invented receptor called Arterin-1, altering vascular smooth muscle tone and showing dose-dependent effects in cell-based assays. There is no empirical evidence for arteriin outside these imagined contexts, and no real-world pharmacokinetic or toxicology data exist.

As a teaching and thought-experiment tool, arteriin helps illustrate concepts in medicinal chemistry, such as receptor pharmacology, assay design, and the importance of rigorous validation before considering any real-world application. It remains a fictional construct without clinical relevance or regulatory status.
