Allosteeriline

Allosteeriline is a term used in theoretical discussions of protein allostery to describe a hypothetical small molecule that acts as a universal allosteric regulator. The name blends allostery with the common chemical suffix -ine. In proposed models, allosteeriline binds to distant allosteric sites and shifts the conformational ensemble of target proteins, thereby altering activity without competing at the active site. Depending on the context, binding is described as stabilizing either active or inactive states, or as inducing biased signaling where different functional outputs are favored.

Because allosteeriline is not a validated compound in experimental literature, there is no defined molecular structure, synthesis route, or binding data. It is mainly used in pedagogical or speculative discussions to illustrate how a single allosteric effector could influence multiple proteins or pathways, highlighting considerations of specificity, cooperativity, and off-target effects in allosteric drug design.

In some theoretical works, allosteeriline is contrasted with classical allosteric modulators that tend to target specific proteins. The term serves as a placeholder for exploring the consequences of universal allosteric modulation, or as a conceptual tool in discussions of conformational landscapes and population shift models such as the Monod-Wyman-Changeux or Koshland-Némethy-Filmer frameworks.
