2-(4-chlorophenyl)-5-(1-piperidinyl)-4-oxazolecarbonitrile

2-(4-chlorophenyl)-5-(1-piperidinyl)-4-oxazolecarbonitrile is a chemical compound with the following structure:

* **2-(4-chlorophenyl):** This part indicates a phenyl ring (a six-membered carbon ring with alternating double bonds) substituted at the para position (opposite to the point of attachment) with a chlorine atom.
* **5-(1-piperidinyl):** This part indicates a piperidine ring (a six-membered ring containing a nitrogen atom) attached at the 5 position of the oxazole ring.
* **4-oxazolecarbonitrile:** This part indicates an oxazole ring (a five-membered ring containing nitrogen and oxygen atoms) with a cyano group (CN) at the 4 position.

This molecule is a **selective antagonist of the 5-HT6 receptor**, which is a serotonin receptor in the brain. This means it binds to the receptor and prevents serotonin from activating it.

**Importance in Research:**

5-HT6 receptors are involved in various brain functions, including learning, memory, and cognition. Antagonists of this receptor have shown potential in research for treating several conditions, including:

* **Alzheimer's disease:** By enhancing cognitive function and memory.
* **Schizophrenia:** By improving cognitive deficits.
* **Obesity:** By reducing appetite and food intake.
* **Depression:** By modulating mood and anxiety.

**2-(4-chlorophenyl)-5-(1-piperidinyl)-4-oxazolecarbonitrile is a valuable research tool** because it allows scientists to study the role of 5-HT6 receptors in these conditions and to develop new drugs that target this receptor.

**Important Note:** This compound is still under research, and its safety and efficacy for human use have not yet been established.
