L-Cystine hydrochloride is an orally active extracellular form of L-Cysteine (HY-Y0337), occurring in proteins of plants and animals. L-Cystine hydrochloride elevates Nrf2 protein expression and activates Nrf2 transcription factor. L-Cystine hydrochloride reduces ROS generation and protects against oxidant- or Doxorubicin (HY-15142A)-induced apoptosis. L-Cystine hydrochloride combined with L-theanine (HY-15121) enhances the production of antigen-specific IgG by increasing glutathione (GSH) levels and T helper 2 (Th2) mediated responses in mice. L-Cystine hydrochloride is promising for research of cystinuria and kidney stones

製品説明

体外実験

L-Cystine hydrochloride (83 µM or 200 µM, 24 h or 72 h) effectively reverses the growth inhibition of both Sulfasalazine (HY-14655) and Erastin (HY-15763) in Huh6 cells^[1].
L-Cystine hydrochloride ( 0.8 mM, 4 h) induces Nrf2 protein expression elevation in a Keap1-dependent manner in HeLa cells^[6].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay^[1]

Cell Line:	Huh6 and Huh7 cells
Concentration:	83 µM or 200 µM
Incubation Time:	72 h or 24 h
Result:	The degree of growth inhibition by Sulfasalazine (HY-14655) or Erastin (HY-15763) was greater in medium containing a physiological level of 83 μM L-Cystine hydrochloride than in medium containing 200 μM L-Cystine hydrochloride in Huh6 and Huh7 cells.

Western Blot Analysis^[6]

Cell Line:	HeLa cells
Concentration:	0.2 mM
Incubation Time:	4 h
Result:	Was sufficient for producing Nrf2 protein elevation at 0.2 mM in HeLa cells.

Western Blot Analysis^[6]

Cell Line:	HeLa cells
Concentration:	0.8 mM
Incubation Time:	4 h
Result:	Induced Nrf2 in a Keap1-dependent manner in HeLa cells.

体内実験

L-Cystine hydrochloride (280 mg/kg, p.o., 11 days) administrated with L-theanine (HY-15121) enhances antigen-specific IgG production partly through augmentation of glutathione (GSH) levels and T helper 2 (Th2)-mediated responses in mice^[2].
L-Cystine hydrochloride (200 mg/kg, p.o., 11 days) administrated with L-theanine (HY-15121) (80 mg/kg, p.o., 11 days) significantly decreases the serum IL-10/IFN-γ ratio 6 hours after DNP-KLH antigenic stimulation, but increases the serum IL-10/IFN-γ ratio 24 hours after DNP-KLH antigenic stimulation in mice^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Nine-week-old female BALB/c mice^[2]
Dosage:	140, 280 and 560 mg/kg
Administration:	p.o. administration for 11 days
Result:	Significantly increased IgG and IgM antibody production administrated with L-theanine (HY-15121) after DNP-dextran and DNP-KLH antigenic stimulation in mice.
