tetramic acid

Tetramic acids are a type of organic compound characterized by a unique four-ring structure that includes both nitrogen and oxygen atoms. They are often found in natural products from fungi, bacteria, and plants and can have biological activities such as antimicrobial, antifungal, or antiviral effects. These compounds are of interest in medicinal research for their potential to develop new drugs. Chemically, tetramic acids are derived from a core structure called an "acyl tetramic acid," and their diverse structures and functions make them important in natural product chemistry and pharmaceutical development.
