title: [The histamine-liberating action of polymyxin B and its analogs].
abstract: Histamine-releasing effect of polymyxin B1 and its deacylated analogues has been studied on purified rat mast cells. The structure-activity analysis showed that cyclic peptide fragment and acyl residue of molecule of polymyxin plays an important role in histamine-releasing activity. Histamine release, induced by polymyxin B1 and its analogue was blocked by metabolic inhibitor antimycin A. Preincubation of polymyxin B1 with lipopolysaccharide inhibits in dose-dependent manner polymyxin-induced histamine secretion from rat mast cells.
