Benzoylurea
Benzoylureas are chemical derivatives of N-benzoyl-N′-phenylurea (benzoylurea). They are best known for their use as insecticides. They act as insect growth regulators by inhibiting synthesis of chitin in the insect's body.
One of the more commonly used benzoylurea pesticides is diflubenzuron. Others include chlorfluazuron, flufenoxuron, hexaflumuron, and triflumuron. Lufenuron is the active compound in flea control medication for pet dogs and cats.
Certain types of benzoylurea compounds have been investigated as potential anticancer agents.
