gliasolut

Gliasolut is a fictional small-molecule agent proposed to modulate glial cell activity in the central nervous system. In speculative neuroscience literature, it is described as a solute that interfaces with glial membranes to promote homeostatic regulation of neuronal signaling, fluid balance, and inflammatory responses.

Chemical and pharmacological properties: In theoretical models, gliasolut is a low‑molar‑mass, water-soluble compound with a predicted molecular weight around 320 Da. It is described as having moderate lipophilicity to allow limited blood‑brain barrier penetration and a pKa compatible with physiological pH. It is proposed to be metabolically stable and reversible in action.

Proposed mechanism: The hypothetical mechanism includes enhancement of astrocytic glutamate uptake, stabilization of calcium signaling, and modulation of aquaporin-4 water channels to improve extracellular milieu. It is also proposed to downregulate microglial pro-inflammatory pathways and promote clearance of extracellular potassium after neuronal activity.

Research status: Gliasolut appears in fictional or speculative experimental contexts rather than established scientific consensus. It has been used in thought experiments and limited co-culture simulations to explore how glial modulation might influence neuronal resilience to excitotoxic stress. There are no validated clinical data supporting its use, and it is not approved for any medical application.
