    Description

    Baicalin, as a flavonoid glycoside, is an allosteric carnitine palmityl transferase 1 (CPT1) activator. Baicalin reduces the expression of NF-κB[1][2][3].

    IC50 & Target[1]

    NF-κB

     

    Autophagy

     

    In Vitro

    Baicalin protects against ischemia-reperfusion injury (IRI) by altering the production of various mediators, including reactive oxygen species (ROS), Toll-like receptor (TLR)2 and TLR4, NF-κB, Bax, and Bcl-2. Baicalin treatment inhibits the increased expression of the proinflammatory cytokines TLR2/4, MyD88, p-NF-κB, and p- IκB, as well as increase the expression of IκB protein, an NF-κB inhibitor[1].
    Cell viability is determined by MTT assay. Compared with control cells, cell viability is significantly decreased in SH-SY5Y cells treated with thrombin. Pre-treatment with Baicalin (5, 10, 20 μM) increases cell viability in a dose-dependent manner compared with cells treated thrombin alone[2].

    In Vivo

    Baicalin pretreatment dose-dependently protects against a loss of renal function, with the two higher doses (10 and 100 mg/kg) significantly decreasing Scr and blood urea nitrogen (BUN) concentrations. Tissue injury, as assessed using a 0-3 point scoring system, is lower for the Baicalin treated groups than for the ischemia-reperfusion (IR)+saline group. Compared with the sham group, malondialdehyde (MDA) content is only slightly up-regulated and the SOD activity is only slightly down-regulated in rats treated with 10 and 100 mg/kg Baicalin, indicating that Baicalin abrogates the increase in oxidative stress following reperfusion[1].

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    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.

    • Protocol 1

    Cell Assay
    [2]

    SH-SY5Y cell lines are cultured in RPMI-1640 medium supplemented with 15% fetal bovine serum at 37°C in an air atmosphere containing 95% air and 5% CO2 with a saturated humidity. Upon a confluence of 60~70%, the SH-SY5Y cells are divided into: (i) control group, incubated in RPMI-1640 medium; (ii) thrombin group, which is subject to thrombin induction (40 U/L) for 6 h based on our pre-experiment; and (iii) Baicalin groups, which are treated by Baicalin (5 μM, 10 μM, or 20 μM) for 2 h before induction of thrombin. Cell viability is measured using MTT assay. Briefly, 15 μL of the MTT solution (5 mg/mL) is added to each well and incubated for 4 h at 37°C. After removing the supernatant, 80 μL DMSO are added into each well. The absorbance is measured at 492 nm using a microplate reader. All experiments are performed in triplicate[2].

    Animal Administration
    [1]

    Rats[1]
    Male Wistar rats weighing 200-250 g are used. Rats are randomly divided into five groups of six rats each: (i) sham group; (ii) IR+saline group; (iii) IR+Baicalin (1 mg/kg) group; (iv) IR+Baicalin (10 mg/kg) group; and (v) IR+Baicalin (100 mg/kg) group. Renal IRI is induced by clamping the left renal artery for 45 min plus a right nephrectomy. Rats are anesthetized through an intraperitoneal injection of pentobarbital sodium (40 mg/kg body weight). After a median abdominal incision, the left renal arteries are clamped for 45 min with serrefine. After clamp removal, adequate restoration of blood flow is checked before abdominal closure. The right kidney is then removed. Sham-operated animals underwent the same surgical procedure without clamping[1].

    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.
