Anilides are chemical compounds that result from the reaction between aniline (a organic compound with the formula C6H5NH2) and a carboxylic acid or its derivative. The resulting compound has the general structure R-CO-NH-C6H5, where R represents the rest of the carboxylic acid molecule.

Anilides are widely used in the pharmaceutical industry to produce various drugs, such as analgesics, anti-inflammatory agents, and antifungal agents. Some examples of anilide-based drugs include acetaminophen (also known as paracetamol), fenacetin, and flufenamic acid.

It's worth noting that some anilides have been found to have toxic effects on the liver and kidneys, so they must be used with caution and under medical supervision.

Allylamine is an organic compound with the formula CH2=CH-CH2-NH2. It is a colorless liquid that is soluble in water and polar organic solvents. Allylamine is used as a building block in the synthesis of various chemical compounds, including pharmaceuticals, agrochemicals, and polymers.

In the medical field, allylamine derivatives are used as antifungal agents. These drugs work by inhibiting the enzyme squalene epoxidase, which is necessary for the synthesis of ergosterol, a key component of fungal cell membranes. By blocking the production of ergosterol, allylamine derivatives disrupt the integrity of fungal cell membranes and prevent the growth of fungi. Examples of allylamine antifungal drugs include terbinafine and naftifine.

Aminopropionitrile is a chemical compound with the formula NPN(H2)CH2CH2CN. It is an irritant that can cause damage to the eyes, skin, and respiratory system. It is used in the manufacture of certain plastics and resins, and has also been studied for its potential effects on the human body. Some research suggests that aminopropionitrile may interfere with the normal functioning of collagen, a protein that helps to provide structure and support to tissues and organs in the body. This has led to interest in the use of aminopropionitrile as a potential treatment for certain conditions related to collagen, such as scleroderma. However, more research is needed to determine the safety and effectiveness of this use.
