Chemical Structure and Properties

Phenylpiracetam is structurally related to piracetam, but it includes a phenyl group that changes its properties.

Relation to Piracetam

Phenylpiracetam shares the core structure of piracetam. Both belong to the racetam family. They have the same molecular backbone: C12H14N2O2.

Piracetam is known for its nootropic effects. Phenylpiracetam has this same base but includes a phenyl group. This addition alters the molecule’s absorption, potency, and overall effect.

Piracetam’s molecular weight is known, but the phenyl group changes this. Phenylpiracetam has a molecular mass of 218.25 Da and a melting point of 131°C. These properties make it unique from other racetams.

Unique Characteristics of the Phenyl Group

The phenyl group is a key feature in phenylpiracetam. This group allows the molecule to dissolve better in fats and lipids.

This increased fat solubility means phenylpiracetam is absorbed more efficiently in the body compared to piracetam. As a result, it crosses the blood-brain barrier more effectively.

This higher potency makes it effective at lower doses. The phenyl group also allows better bioavailability, which enhances its cognitive effects. This structure likely explains its broader use, from aiding cosmonauts to potential therapeutic applications.

Mechanism of Action

Phenylpiracetam affects various neurotransmitter systems and efficiently crosses the blood-brain barrier, making it a potent nootropic.

Interaction with Neurotransmitter Systems

Phenylpiracetam binds to different neurotransmitter receptors. One of its key interactions is with the nicotinic acetylcholine receptors in the cerebral cortex. These receptors play a critical role in cognitive function and memory. Phenylpiracetam acts as a synaptic transmission modulator, which can enhance cognitive processes.

It has been found not to interact with GABA-A or GABA-B receptors, nor with dopamine and serotonin receptors. Its modulation of the cholinergic system, particularly through acetylcholine, is notable. Phenylpiracetam also impacts glutamate receptors, which are crucial for synaptic plasticity and learning.

Blood-Brain Barrier Permeability

This compound crosses the blood-brain barrier swiftly and efficiently. Phenylpiracetam’s lipophilic structure aids in its high permeability. Once in the brain, it accumulates in neuronal tissue, which boosts its efficacy. This rapid entry and accumulation enable it to exert its effects more potently compared to piracetam.

The efficient crossing enhances its stimulant properties, making it effective for cognitive enhancement. This property is essential for its therapeutic uses, as rapid brain entry means quicker onset of action. The ability to permeate the blood-brain barrier distinguishes phenylpiracetam from other nootropics.
