What is "cinchophen"

n. An analgesic drug used to treat gout in animals (and, until the 1930s, in humans, when it was found to cause liver damage).

Cinchophen (trade names Atophan, Quinophan, and Phenaquin) is an analgesic drug that was introduced in 1910 and frequently used to treat gout. This drug is still used, in combination with Prednisolone, by veterinarians to treat arthritis in animals.

It can be prepared starting from anilin, benzaldehyde and pyruvic acid in absolute ethanol.

Use of this drug in humans ceased in the 1930s due to the discovery that cinchophen can cause serious liver damage.

There is some evidence that it stimulates C-Fos.
