The present invention relates to bioactive cyclic compounds and their use as antimicrobial agents. In particular, the present invention relates to barbiturate mimics of Eusynstyelamides or small antimicrobial peptides. The compounds of the invention are represented by Formula (I). (I) 

Barbituric acid derivatives comprising cationic and lipophilic groups

The invention provides a method of treating tumors by adminstering to a human or animal patient an effective amount of a molecule of 2 to 4 amino acids or equivalent subunits in length, which incorporates a bulky and lipophilic group comprising at least 13 non-hydrogen atoms and containing no more than 2 polar functional groups, in which the bulky and lipophilic group incorporates one or more closed rings of 5 or more non-hydrogen atoms, and in which the molecule further has at least two more cationic than anionic moieties.

Method of treating tumors

The invention relates to the use of a molecule comprising a backbone of 2 to 35 non-hydrogen atoms in length, having covalently attached thereto at least two bulky and lipophilic groups and having at least one more cationic than anionic moiety, in the manufacture of a medicament for destabilizing microbial cell membranes and the use as a membrane acting antimicrobial agent of a molecule comprising a backbone of 2 to 35 non-hydrogen atoms in length, having covalently attached thereto a super bulky and lipophilic group comprising at least 9 non-hydrogen atoms and having at least two more cationic than anionic moieties and to methods of treatment involving such molecules, in particular peptides including peptide derivatives, and peptidomimetics.
