Application


  • Metabolic Labeling Strategy Boosted Antibacterial Efficiency for Photothermal and Photodynamic Synergistic Bacteria-Infected Wound Therapy.: This study demonstrates the enhanced antibacterial efficiency of a metabolic labeling strategy using ᴅʟ-Propargylglycine in photothermal and photodynamic therapy for treating bacteria-infected wounds (Li et al., 2022).

  • Metabolic Labeling of Peptidoglycan with NIR-II Dye Enables In Vivo Imaging of Gut Microbiota.: This research utilizes ᴅʟ-Propargylglycine for metabolic labeling, allowing near-infrared II imaging of gut microbiota in vivo, providing new insights into microbiome studies (Wang et al., 2020).

  • Hydrogen sulfide upregulated mRNA expressions of sodium bicarbonate cotransporter1, trefoil factor1 and trefoil factor2 in gastric mucosa in rats.: Investigates the role of ᴅʟ-Propargylglycine, in upregulating specific mRNA expressions in gastric mucosa, with implications for gastrointestinal research (Cheraghi et al., 2016).

Biochem/physiol Actions

DL-Propargylglycine (PAG) is an irreversible inhibitor of the enzyme cystathionine γ-lyase (GCL), a key enzyme involved in glutathione synthesis and the metabolic transsulfuration pathway which regulates homocysteine concentration and mediates cysteine synthesis. Treatment of animal disease models with PAG was shown to alleviate symptoms of diseases that impair the formation or action of hydrogen sulfide (H2S).

The transsulfuration pathway, which aids in regulating homocysteine concentration and mediates cysteine synthesis, may be sensitive to vitamin B-6 status because cystathionine beta-synthase (CBS) and cystathionine gamma-lyase (CGL) require pyridoxal 5'-phosphate (PLP). To assess relations between vitamin B-6 and transsulfuration

Tuberculosis, especially multidrug resistant cases, remains an enormous public health threat. Mycobacterium tuberculosis metC (Rv3340) an enzyme involved in methionine biosynthesis was identified and characterised for antimicrobial susceptibility. We reported that the overexpression of Rv3340 in Mycobacterium smegmatis (Ms_Rv3340) produces

Hydrogen sulphide (H2S) is increasingly being recognized as an important signalling molecule in the cardiovascular and nervous systems. The production of H2S from L-cysteine is catalysed primarily by two enzymes, cystathionine gamma-lyase and cystathionine beta-synthase. Evidence is accumulating to demonstrate
