Metabolite Identification
Common NamePseudodesmin A
DescriptionPseudodesmin A is a cyclic lipodepsipeptide belonging to the chemical class of cyclic lipopeptides (CLiPs). This metabolite, produced by Pseudomonas, exhibits significant antimicrobial activity, effectively killing certain bacteria at minimal inhibitory concentrations in the single micromolar range, likely through the permeabilization of cellular membranes (PMID:34594308 ). Research has shown that the enantiomer of pseudodesmin A retains identical activity against a variety of Gram-positive bacterial strains, indicating its robust antimicrobial properties (PMID:32373092 ). The molecular determinants of its activity have been investigated, revealing insights into its structure-function relationships (PMID:32373092 ). Additionally, a total organic synthesis route has been developed to create novel analogs of pseudodesmin A, further elucidating the links between molecular constitution and biological activity (PMID:32373092 ). Structural models have been proposed to describe the interactions of pseudodesmin A with membrane environments, enhancing our understanding of its peptide-membrane interactions (PMID:32373092 ). This cyclic lipodepsipeptide, along with other CLiPs, has been tested against a broad panel of mainly Gram-positive bacteria, confirming its potential as an antimicrobial agent (PMID:28007479 ).
