virulence

Sodium houttuyfonate is anti-pseudomonas agents, inhibits virulence-related motility of Pseudomonas.

Sodium lauryl sulfoacetate (Sodium houttuyfonate) is anti-pseudomonas agents, inhibits virulence-related motility of Pseudomonas.

D-Cysteine, the D-isomer of cysteine, is a powerful inhibitor of E. coli growth and is mediated by D-amino acid oxidase to produce H2S, serving as a neuroprotective agent against cerebellar ataxia. Additionally, D-cysteine can inhibit the growth and cariogenicity of a two-species biofilm formed by Streptococcus mutans and Streptococcus hemoglobin.

N-acetyltyramine is a metabolite of the biogenic amine tyramine . It enhances cytotoxicity of doxorubicin in resistant P388 murine leukemia cells with an IC50 value of 0.13 μg ml compared with an IC50 value of 0.48 μg ml for doxorubicin alone.

Equisetin, an N-methylserine-derived acyl tetramic acid isolated from the terrestrial fungus Fusarium equiseti NRRL 5537, functions as a Quorum-sensing inhibitor (QSI) that specifically attenuates QS-regulated virulence phenotypes in P. aeruginosa, presenting a potent lead for treating P. aeruginosa infections without hindering bacterial growth. This tetramate-containing natural product possesses antibiotic and cytotoxic properties, effectively inhibiting the growth of Gram-positive bacteria and HIV-1 integrase activity, yet it does not impact Gram-negative bacteria.

Cyclic di-GMP (c-di-GMP) diammonium is a STING activator and a global bacterial second messenger, which regulates biofilm formation, motility, and virulence in diverse bacterial species .

Cyclic di-GMP sodium (c-di-GMP sodium) is a STING activator and a ubiquitous second messenger that regulates biofilm formation, motility and virulence of various bacteria.

PSMα3 is a peptide compound that can be utilized to induce tolerance in dendritic cells (DCs) for DC vaccination strategies. It effectively penetrates and modulates human monocyte-derived DCs by modifying the maturation process induced by TLR2 or TLR4. Additionally, PSMα3 inhibits the production of both pro- and anti-inflammatory cytokines and decreases antigen uptake. Notably, PSMα3 is a significant virulence factor released by the most pathogenic strains of methicillin-resistant Staphylococcus aureus (MRSA).

Cyclic-di-GMP, a STING agonist and ubiquitous second messenger, regulates biofilm formation, motility, and virulence in various bacterial species.

Cis-2-dodecenoic acid, identified in Burkholderia cenocepacia, disrupts bacterial quorum sensing, thereby inhibiting biofilm formation and the production of virulence factors [1].

Moscatin (Plicatol, 4-methoxyphenanthrene-2,5-diol) is a diphenyl derivative that can be extracted from Dendrobium nobile Lindl. It inhibits arachidonic acid-induced platelet aggregation, and is able to inhibit Candida albicans virulence and growth by down-regulating the expression of genes such as ERG, HSP, and ALS.

Cyclo(L-Pro-L-Val), a 2,5-diketopiperazine extracted from the fruits of Mycobacterium chiliolyticum AZ2 and Mycobacterium leprae, possesses anti-inflammatory activity and virulence activity against phytopathogenic microorganisms (e.g., R. fascians LMG 3605) and inhibits Gram-positive plant pathogens.Cyclo(L-Pro-L-Val) significantly inhibited IKKα phosphorylation and IκBα and NF-κB activation as well as iNOS and COX-2 activation in a concentration Cyclo(L-Pro-L-Val) significantly inhibited the phosphorylation of IKKα, IKKβ, IκBα, and NF-κB, as well as the activation of iNOS and COX-2 in a concentration-dependent manner, and is a potential therapeutic agent for the treatment of inflammation-related diseases.
