The present invention relates to substituted 5-aryl-2-aminoimidiazole compounds being active against microbial biofilm formation. The invention also relates to compositions comprising a microbial biofilm inhibiting amount of said substituted 5-aryl-2-aminoimidiazole compounds in combination with excipients. Methods for inhibiting or controlling microbial biofilm formation in a plant, a body part of a human or an animal, or a surface with which a human or an animal may come into contact are also disclosed.

Compounds, compositions, and methods for controlling biofilms

The invention relates to substituted 2-aminoimidazoles and their imidazo[1,2-a]pyrimidinium salts precursors being active against biofilm formation. The invention also relates to imidazo[1,2-a]pyrimidinium salts bearing an azidoalkyl substituent, and to substituted 2-aminoimidazoles wherein the amino group bears a terminal heterocyclic group such as a triazolyl group which are formed through azide-alkyne Huisgen cycloaddition starting from said imidazo[1,2-a]pyrimidinium salts bearing an azidoalkyl substituent. The invention also relates to a class of N-(azidoalkyl)pyrimidin-2-amines useful as starting materials for the synthesis of said imidazo[1,2-a]pyrimidinium salts bearing an azidoalkyl substituent. The invention also relates to antimicrobial compositions that include a microbial biofilm formation inhibiting amount of such substituted 2-aminoimidazoles or imidazo[1,2-a]pyrimidinium salts in combination with excipients. Methods for inhibiting or controlling microbial biofilm formation in a plant, a body part of a human or an animal, or a surface with which a human or an animal may come into contact are also disclosed.
