摘要

Tolaasin I and the White Line Inducing Principle (WLIP) are lipodep-sipeptides (LDPs) produced by virulent strains of Pseudomonas tolaasii and reactans which are the causal agents of "brown blotch" disease of Agaricus bisporusand of the "yellowing" of Pleurotus ostreatus. Both tolaasin I and WLIP havehaemolytic activity, permeabilize lipid vesicles and appear to be involved in mush-room tissue alterations by forming transmembrane pores. Herein, we describe theactivity of tolaasin II and five natural tolaasin analogues on natural and modelmembranes. Tolaasin I and tolaasin II shared similar activity; the other tolaasin ana-logues were instead remarkably less active (up to 15 times when compared to tolaasin I)both on natural and model membranes. Additionally, the activity of mixtures formedby tolaasin I and WLIP on vesicles is reported. Preliminary evidences of an interac-tion of the two LDPs leading to an antagonistic action became apparent.
