Discovery and development of cyclooxygenase 2 inhibitors

Imagine your body is like a big factory that makes different things for your body to work properly. And one of the things your body makes are called prostaglandins. Prostaglandins are like the managers of the factory, they tell your body what to do when there's an injury or when it needs to protect itself.

One thing prostaglandins do is make you feel pain when you get hurt. When you touch something hot, prostaglandins can make your skin hurt so you take your hand away. Prostaglandins are also responsible for inflammation, which is when your body swells up and gets red when you get a cut or a bruise.

Scientists discovered that there were two types of cyclooxygenase enzymes in your body, COX-1 and COX-2. These enzymes help create prostaglandins.

It was found that COX-1 enzymes were responsible for making the good prostaglandins that protect your stomach lining and help with blood clotting. But COX-2 enzymes made the bad prostaglandins that cause inflammation and pain.

So they came up with this idea: what if we could create a drug that would target just the COX-2 enzyme and stop it from making the bad prostaglandins?

Scientists started to work on this idea and found that they could create drugs that would block the COX-2 enzyme, but not the COX-1 enzyme. These drugs were called COX-2 inhibitors.

COX-2 inhibitors have been used to help treat pain and inflammation caused by conditions like arthritis. They've also been used to help prevent certain types of cancer.

However, it's important to note that COX-2 inhibitors can have side effects, like stomach problems or heart issues. So doctors have to be very careful when they prescribe these drugs and make sure they're safe for the patient.
