Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Leachianone A as a potential anti-cancer drug by induction of apoptosis in human hepatoma HepG2 cells.[Pubmed: 17379399]
    The Chinese herbal medicine Radix Sophorae is widely applied as an anti-carcinogenic/ anti-metastatic agent against liver cancer.
    In this study, Leachianone A, isolated from Radix Sophorae, possessed a profound cytotoxic activity against human hepatoma cell line HepG2 in vitro, with an IC(50) value of 3.4microg/ml post-48-h treatment. Its action mechanism via induction of apoptosis involved both extrinsic and intrinsic pathways. Its anti-tumor effect was further demonstrated in vivo by 17-54% reduction of tumor size in HepG2-bearing nude mice, in which no toxicity to the heart and liver tissues was observed.
    In conclusion, this is the first report describing the isolation of Leachianone A from Radix Sophorae and the molecular mechanism of its anti-proliferative effect on HepG2 cells.

    Lavandulyl flavonoids with sodium-dependent glucose cotransporter 2 inhibitory activity from Sophora flavescens.[Reference: WebLink]
    To discover new bioactive Sodium-dependent glucose cotransporter 2(SGLT2)inhibitors from the traditional Chinese medicine"Ku Shen"(roots of Sophora flavescens),the bioassay-guided purification of an active ethyl acetate fraction was performed.
    Sixteen lavandulyl flavonoids were isolated and their structures were elucidated as kushenol H(1),kushenol K(2),kurarinol(3),kushenol Y(4),kushenol P(5),norkurarinone(6),kushenol I(7),kushenol N(8),(-)-kurarinone(9),kushenol X(10),neokurarinol(11),kushenol C(12),sophoraflavanone G(13),Leachianone A(14),kuraridine(15)and kushenol A(16).All isolated compounds exhibited inhibitory activity against SGLT2.Among them,the two main constituents of the active EtOAc fraction,(-)-kurarinone(9)and sophoraflavanone G(13)showed the most potential inhibitory activity against SGLT2with the IC50values of 2.24μmol/L and 1.45μmol/L,respectively.

    Inhibitory Effects of Leachianone A from Sophora flavescens Ait. against Cadmium Induced Cytotoxicity.[Reference: WebLink]
    In this study, cytotoxicity of cadmium on NIH 3T fibroblasts was utilized in order to discover antitoxic compound in methanol extract of Sophora flavascens Ait.
    There were treatment groups; control (medium only), MTT50 group and five experimental groups. MTT {3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H- tetrazoliumbromide} assay was performed to evaluate the cytotoxicity of cell organelles and IC50 was also measured. Accordingly we have examined the detoxification effects of methanol extract of S. flavescens Ait. and Leachianone A (LA) on cadmium-treated NIH 3T3 fibroblasts (IC50= 12.5 μM) to observe morphological changes by the light microscopy. Both S. flavescens Ait. methanol extract and LA showed inhibitory effects on cadmium-induced cytotoxicity. Furthermore, LA showed dose-dependency in detoxication.
    From these results, it is conceivable to suggest that LA from S. flavescens Ait. methanol extract is a potential antitoxic agent.
