Application


  • Effects of DL-homocysteine thiolactone on cardiac contractility, coronary flow, and oxidative stress markers in the isolated rat heart: This investigation demonstrates the effects of DL-homocysteine thiolactone on heart function, offering insights into its use in cardiovascular research and potential therapeutic applications (Zivkovic et al., 2013).

  • Homocysteine is a novel risk factor for suboptimal response of blood platelets to acetylsalicylic acid in coronary artery disease: The study explores how L-homocysteine thiolactone could affect platelet responses in therapy for coronary artery diseases, pointing to its importance in cardiovascular therapeutics (Karolczak et al., 2013).

Biochem/physiol Actions

L-Homocysteine thiolactone, an amine reactive agent, is used to study post-translational modification of proteins, especially at lysine residues.

We have shown that homocysteinemic rabbits have altered fibrinogen that forms fibrin clots with increased resistance to fibrinolysis. Homocysteine thiolactone is a metabolite of homocysteine (Hcys) that can react with amines and introduce a new sulfhydryl group into proteins. Recent

Hyperhomocysteinemia is known to cause degeneration of retinal ganglion cells, but its influence on photoreceptors remains largely unknown. In particular, the role of homocysteine-thiolactone (Hcy-T)--the physiologic metabolite of homocysteine that has been proven to be more cytotoxic than homocysteine itself--as

Homocysteine (Hcys) and homocysteine thiolactone (HTL) concentrations in organism are correlated with a number of serious pathologies. In the literature, there are few papers describing studies on the effects of homocysteine on proteins that participate in blood coagulation and fibrinolysis
