Controlling bacterial behavior with indole-containing natural products and derivatives

TETRAHEDRON, 70(37), 6363–6372.

By: R. Melander n, M. Minvielle n & C. Melander n

author keywords: Indole; Bacterial communication; Anti-virulence; Biofilm; Antibiotic resistance
TL;DR: An overview of the process controlled by indole signaling is given, current efforts to design indole-containing small molecules to intercept these pathways are summarized, and the synthetic efforts towards accessing indole derived bioactive small molecules are detailed.

Highly Active Modulators of Indole Signaling Alter Pathogenic Behaviors in Gram-Negative and Gram-Positive Bacteria

CHEMISTRY-A EUROPEAN JOURNAL, 19(51), 17595–17602.

By: M. Minvielle n, K. Eguren n & C. Melander n

author keywords: desformylflustrabromine; mechanistic probes; natural products; phenotype control; structure-activity relationships
MeSH headings : Bacterial Proteins / antagonists & inhibitors; Bacterial Proteins / metabolism; Biofilms / drug effects; Gram-Negative Bacteria / drug effects; Gram-Negative Bacteria / physiology; Gram-Positive Bacteria / drug effects; Gram-Positive Bacteria / physiology; Hydrocarbons, Brominated / chemical synthesis; Hydrocarbons, Brominated / chemistry; Hydrocarbons, Brominated / pharmacology; Indole Alkaloids / chemical synthesis; Indole Alkaloids / chemistry; Indole Alkaloids / pharmacology; Indoles / chemical synthesis; Indoles / chemistry; Indoles / pharmacology; Phenotype; Structure-Activity Relationship; Temperature; Trans-Activators / antagonists & inhibitors; Trans-Activators / metabolism; Tryptophanase / antagonists & inhibitors; Tryptophanase / metabolism
TL;DR: This investigation demonstrates that molecules based on the dFBr scaffold can alter pathogenic behaviors by mimicking indole-signaling pathways and develop non-microbicidal dF Br derivatives that are 27-2000 times more active than indole in modulating biofilm formation, motility, acid resistance, and antibiotic resistance.

Indole-triazole conjugates are selective inhibitors and inducers of bacterial biofilms

MEDCHEMCOMM, 4(6), 916–919.

By: M. Minvielle n, C. Bunders n & C. Melander n

TL;DR: Structural/function studies revealed that the addition of a bromine atom at the 2-position of the indole/triazole scaffold altered activity against both Gram-negative and Gram-positive bacteria and could transform a biofilm inhibitor into aBiofilm inducer. (via Semantic Scholar)

Intercepting Bacterial Indole Signaling with Flustramine Derivatives


By: C. Bunders n, M. Minvielle n, R. Worthington n, M. Ortiz n, J. Cavanagh n & C. Melander n

MeSH headings : Escherichia coli / metabolism; Hydrocarbons, Brominated / metabolism; Indole Alkaloids / metabolism; Indoles / metabolism; Signal Transduction; Staphylococcus aureus / metabolism
TL;DR: DFBr derivatives are found that are 10-1000 times more active than indole itself, demonstrating that the flustramine family of indolic natural products represent a privileged scaffold for the design of molecules to control pathogenic bacterial behavior. (via Semantic Scholar)
