    Pyoluteorin

    ¥3,820.75 - ¥13,332.75

    Pyoluteorin is a small chlorinated pyrrol produced by several species of Pseudomonas, first reported in 1958. Pyoluteorin has a broad bioprofile, demonstrating antibiotic, antifungal and herbicidal activity. More recently, Pyoluteorin has been investigated as a bio-pesticide and has been shown to modulate the levels of metabolites in Pseudomonas.

    Pyoluteorin is soluble in ethanol, methanol, DMF and DMSO.  Limited water solubility.

    Molecular Formula C11H7Cl2NO3
    Plant Biology Applications Pyoluteorin autoregulation in the rhizosphere was assessed with cucumber seedlings in soil and cross-feeding experiments. Expression of a pyoluteorin biosynthesis gene by a pyoluteorin-deficient mutant of Pf-5 was enhanced by Pyoluteorin produced by coinoculated cells of Pf-5. Thus, Pyoluteorin is an autoregulatory compound and functions as a signal molecule influencing the spectrum of secondary metabolites produced by the bacterial cell.
    Cancer Applications The pharmacophore of Pyoluteorin derivatives are promising as Mcl-1 antagonists against Mcl-1-dependent hematological cancers.
