Application

N-(2-Mercaptopropionyl)glycine or Tiopronin has been used:
  • in the preparation of polyethylenimine (PEI)-coated gold microparticles (PEI-gold) for biolistic delivery of nucleic acids
  • to study the role of reactive oxygen species (ROS) at the reperfusion stage in in vivo isoflurane preconditioning-induced neuroprotection
  • as a ROS inhibitor to study its effect on lysophosphatidylcholine (LPC)-induced inflammasome activation

Biochem/physiol Actions

N-(2-Mercaptopropionyl)glycine (NMPG) is a thiol compound associated with autoimmune hypoglycemia. It is a diffusible antioxidant and reduces the severity of colonic injury. NMPG also relieves myeloperoxidase activity and stimulates hypoxia-inducible factor-1 (HIF-1) - vascular endothelial growth factor (VEGF) pathway for ulcer healing.
N-(2-Mercaptopropionyl)glycine is a free radical scavenger.

Emulsified isoflurane (EI) has been shown to alleviate myocardial ischemia-reperfusion (IR) injury. However, previous reports have not been focused on the underlying mechanism. We used models of IR injury in Langendorff-isolated rat hearts to determine the relationship between the mechanism

The present study characterized the in vitro biological response of a comprehensive set of cancer cell lines to gold nanoparticles (2.7 nm) coated with tiopronin (AuNPs-TP). Our findings suggest that upon entering cells, the AuNPs-TP are sequestered in vacuoles such

Well-dispersed gold nanoparticles (NP) coated with tiopronin were synthesized by X-ray irradiation without reducing agents. High-resolution transmission electron microscopy shows that the average core diameters of the NPs can be systematically controlled by adjusting the tiopronin to Au mole ratio
Andrew S Goldsborough et al.
Journal of medicinal chemistry, 54(14), 4987-4997 (2011-06-11)
A major challenge in the treatment of cancer is multidrug resistance (MDR) that develops during chemotherapy. Here we demonstrate that tiopronin (1), a thiol-substituted N-propanoylglycine derivative, was selectively toxic to a series of cell lines expressing the drug efflux pump
