Description

Penicillin G sodium salt is a typical β-lactam antibiotic.

IC50 & Target

β-lactam

 

In Vitro

The Ultraviolet-visible (UV-Vis) absorption spectrum of the Penicillin G sodium salt-TEM-1 system is markedly different to that of Penicillin G sodium salt and TEM-1 β-lactamase, indicating the formation of new complexes between Penicillin G sodium salt and TEM-1 β-lactamase. The UV-Vis absorption of TEM-1 β-lactamase increases and a slight red-shift occurs as the concentration of Penicillin G sodium salt increasing, indicating that the interaction between Penicillin G sodium salt and TEM-1 β-lactamase results in subtle conformational changes of TEM-1 β-lactamase[1].

In Vivo

In the logistic regression model, the probability of a positive swab in the control group is 1.6 times higher than that in the pigs treated with Penicillin G sodium salt (P<0.05). In the control group, the risk of a swab having 10 to 99 colonies per plate, compare to having zero per plate, is 2.3 times greater than that in the pigs treated with Penicillin G sodium salt (P=0.022)[2].

In Vivo:

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

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (7.02 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (7.02 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Kinase Assay
[1]

At 278 K, various concentrations of Penicillin G sodium salt, cefalexin and cefoxitin solutions are added to TEM-1β-lactamase solution (5×10-6 M). The concentrations of the three antibiotics are gradually increased from 0 to 25×10-6 M. Following mixing and interaction for 2 min, the Ultraviolet-visible (UV-Vis) absorption spectra are recorded on a spectrophotometer with a slit of 2 nm and scanning speed of 400 nm/min using 0.02 M phosphate buffer (pH 7.0) as a reference[1].

Animal Administration
[2]

A randomized complete block design with 2 replicates is used for this study. Each replicate includes 448 pigs, with 16 pens and 28 pigs per pen. Pigs are also sorted by weight; such that animals of similar weight based on visual observation are grouped together within blocks. Two treatments are randomly assigned within each block of 2 contiguous pens using a formal randomization process. The treatment groups are Control (no treatment given) and Treated (Penicillin G sodium salt). Penicillin G sodium salt is administered via the drinking water for 5 d over 2 periods of treatment. The first treatment period commences on the day of weaning, when the pigs are moved into the nursery barns (Day 1) and ends on Day 5. The second treatment period begins on Day 21 and ends on Day 25. The Control group does not receive treatment[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.
