(3-amino-5-nitro-2-benzofuranyl)-phenylmethanone

(3-amino-5-nitro-2-benzofuranyl)-phenylmethanone, also known as **nifedipine**, is a **calcium channel blocker**. It is not a research chemical but a **well-established pharmaceutical drug** used to treat **high blood pressure** and **angina pectoris**.

Here's why it's important for research:

* **Understanding calcium channels:** Nifedipine has been instrumental in understanding the role of calcium channels in various physiological processes, particularly in the cardiovascular system. It helped researchers elucidate how blocking calcium channels leads to vasodilation and reduced heart contractility, ultimately lowering blood pressure.
* **Developing new drugs:** Nifedipine's success paved the way for the development of other calcium channel blockers with similar therapeutic effects but improved properties, such as longer duration of action and fewer side effects.
* **Investigating disease mechanisms:** Nifedipine is used in research to investigate the role of calcium dysregulation in various diseases, including hypertension, angina, migraines, and epilepsy.

**Important Note:** Nifedipine is a prescription drug. It should only be used under the guidance of a healthcare professional. Using it without proper medical supervision can be dangerous and have serious consequences.
