生物活性

G-418 disulfate (Geneticin sulfate), is an aminoglycoside antibiotic, inhibits protein synthesis in eukaryotes and prokaryotes. G-418 disulfate is commonly used as a selective agent for eukaryotic cells[1].

体外研究
(In Vitro)

G418 sulfate, an aminoglycoside neomycin analogue, interferes with protein synthesis and has been used extensively for selection of mammalian cell lines that possess neomycin resistance (NR). The neomycin resistance (neo) gene is frequently used in eukaryotic vectors as a dominant selectable gene. G418 can be covalently bound to asialoorosomucoid (AsOR) to form a conjugate for hepatocyte-specific targeting and toxicity[2].
The human GD3 synthase cDNA was transfected into MDA-MB231 cells, and G-418 bulk selection was used to select cells stably overexpressing the GD3 synthase[2]. An aminoglycoside antibiotic, G418, has been shown to be an inhibitor of many pro- and eukaryotes at concentrations from 1-300 microgram/ml[4].

Animal Administration
[3]

To characterize the sensitivity of the trypanosome populations to G418 in vivo, bloodstream forms of T. brucei brucei GUTat 3.1 and T. brucei brucei GUTat 3.1/BBR3 are expanded separately in sublethally irradiated mice. Prior to the first peak of parasitemia, trypanosomes are collected, and aliquots containing 106 trypanosomes are inoculated intraperitoneally into mice. Twenty-four hours following infection, the mice are divided into groups and treated with G418 at a dose of 10, 20, 30, 40, 50, or 80 mg/kg of body weight (bw) by inoculating intraperitoneally 0.2 mL of the drug in sterile water. At 24 and 48 h following the first treatment, G418 is administered to animals in each group at the same dose as before, resulting in three treatments per mouse. Repeated drug treatments are necessary to ensure complete elimination of nontransfected GUTat 3.1 parasites from the mice. Mice are then monitored daily, for 33 days, for the presence of parasites by microscopic examination of wet-blood films. Animals found to be parasitemic are recorded and then removed from the experiment.

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

DNA/RNA Synthesis[1]
体外研究
(In Vitro)

Bleomycin (BLM) sulfate is chosen as the best-studied micronucleus (MN) inducers in human lymphocytes with different mechanisms of genotoxicity. The most frequent Bleomycin-induced DNA lesions are single and double strand breaks and single apuinic/apyrimidinic sites. At the same time Bleomycin is true radiomimetic compound, resembling almost completely the genetic effect of ionizing radiation[1].
The IC50 value of Bleomycin sulfate for UT-SCC-19A cell line is 4.0±1.3 nM. UT-SCC-12A and UT-SCC-12B are both more resistant to Bleomycin (BLM); IC50 values are 14.2±2.8 nM and 13.0±1.1 nM, respectively[2].
Bleomycin sulfate (50, 100 μM; for 24, 48 h) induce pulmonary fibrosis in RLE-6TN cell (50 μM) and A549 cell (100 μM)[4].

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

Bleomycin sulfate treatment (3.5-4.0 mg/kg; intra-tracheal) on day 0, body weights decreases by day 4 then increases by Day 7 through the end of the study[3].
Bleomycin sulfate (3.5-4.0 mg/kg; intra-tracheal) produces a statistically significant increase in lung hydroxyproline levels, and also increases right caudal lung lobe mass[3].
Bleomycin sulfate (intratracheal instillation; 5.0 mg/kg/day) induces pulmonary fibrosis in eighty 8-week-old male BALB/c mice with weight about 20-30 g. Bleomycin induces the expression levels of α-SMA and collagen I[4].
Bleomycin sulfate (intratracheally; 2.5 mg/kg; 1.25 mg/ml, approximately 50 µl per mouse) induces pulmonary fibrosis in male C57BL/6 mice (8 weeks old, average weight approximately 24.5 g)[5].

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

Animal Model: Male Fischer 344 rats, 8-10 week old, weighing 150-250 g[3]

Astragaloside II is a natural isolated from Astragalus. IC50 value: Target: In vitro: In vivo: The developed and validated method has been successfully applied to the quantification and pharmacokinetic study of AST II in rats after intravenous and oral administration of AST II. The oral absolute bioavailability (F) of AST II was calculated to be 0.79 ± 0.16% with an elimination half-life (t1/2) value of 1.92 ± 0.30 h, suggesting its poor absorption and/or strong metabolism in vivo [1].

PEG300 (Polyethylene glycol 300), a neutral polymer of molecular weight 300, is a water-soluble, low immunogenic and biocompatible polymer formed by repeating units of ethylene glycol[1][2].

体外研究
(In Vitro)

The FDA has approved polyethylene glycol (PEG) for use as a vehicle or base in foods, cosmetics and pharmaceuticals, including injectable, topical, rectal and nasal formulations. PEG shows little toxicity, and is eliminated from the body intact by either the kidneys (for PEGs < 30 kDa) or in the faeces (for PEGs > 20 kDa). PEG lacks immunogenicity, and antibodies to PEG are generated in rabbits only if PEG is combined with highly immunogenic proteins[3].

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

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
The final concentration of PEG300 can go up to 50% in the formulations for intravenous and intramuscular injection without any toxic effects. When administered orally, the highest concentration of PEG300 can reach up to 90%[4][5].

Vancomycin hydrochloride is an antibiotic for the treatment of bacterial infections. It acts by inhibiting the second stage of cell wall synthesis of susceptible bacteria. Vancomycin also alters the permeability of the cell membrane and selectively inhibits ribonucleic acid synthesis.

IC50 Target

Bacterial[1]
体外研究
(In Vitro)

Vancomycin is a large glycopeptide compound with a molecular weight of 1450 Da[1]. Vancomycin is a unique glycopeptide structurally unrelated to any currently available antibiotic. It also has a unique mode of action inhibiting the second stage of cell wall synthesis of susceptible bacteria. Vancomycin is active against a large number of species of Gram-positive bacteria, such as Staphylococcus aureus, Staph. epidermidis, Str. agalactiae, Str. bovis, Str. mutans, viridans streptococci, enterococci[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究
(In Vivo)

Vancomycin is administered intravenously, with a standard infusion time of at least 1 h, to minimize infusion-related adverse effects. Subjects with normal creatinine clearance, vancomycin has an α-distribution phase of 30 min to 1 h and a β-elimination half-life of 6-12 h. The volume of distribution is 0.4–1 L/kg. The binding of vancomycin to protein ranges from 10% to 50%. Factors that affect the overall activity of vancomycin include its tissue distribution, inoculum size, and protein-binding effects[1]. Vancomycin treatment of infected mice is associated with improved clinical, diarrhea, and histopathology scores and survival during treatment[3].

Animal Administration
[3]

Mice: One set of experiments is performed in which infected mice are treated with vancomycin (50 mg/kg) daily for 1, 2, 3, or 5 days and are observed for 21 days postinfection or with vancomycin (20 mg/kg) daily for either 5 or 10 days and monitoring for 15 days postinfection[3].

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