L-Cystathionine
Based on 1 publication(s) in Google Scholar
L-Cystathionine is a nonprotein thioether and is a key amino acid associated with the metabolic state of sulfur-containing amino acids. L-Cystathionine protects against Homocysteine-induced mitochondria-dependent apoptosis of vascular endothelial cells (HUVECs). L-Cystathionine plays an important role in cardiovascular protection.

Homocysteine obviously induces the apoptosis of HUVECs, and this effect is significantly attenuated by the pretreatment with L-cystathionine. Furthermore, L-cystathionine decreases the production of mitochondrial superoxide anion and the expression of Bax and restrained its translocation to mitochondria, increases mitochondrial membrane potential, inhibits mitochondrial permeability transition pore (MPTP) opening, suppresses the leakage of cytochrome c from mitochondria into the cytoplasm, and downregulated activities of caspase-9 and caspase-3[1].
L-Cystathionine is an important metabolic intermediate in the L-cysteine transsulfuration pathway from L-methionine via L-homocysteine in mammalian tissues[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
