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.

Description

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[1][2].

IC50 & Target[1]

Human Endogenous Metabolite

 

In Vitro

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
