In this laboratory investigations are being made to identify and characterise novel antibacterial peptides. With this in mind, the antibacterial properties of human bronchoalveolar lavage (BAL) fluid from sarcoidosis patients is being investigated. In this communication we report on the identification and characterisation of a highly active non\u2010peptide antibacterial compound isolated from BAL fluid. The structure of this active compound was elucidated by high\u2010resolution accurate mass and tandem mass spectrometry to be guanidine,\n                    <jats:italic>N<\/jats:italic>\n                    \u2010[3\u2010[(aminoiminomethyl)amino]propyl]\u2010\n                    <jats:italic>N<\/jats:italic>\n                    \u2010dodecyl\u2010.
