Fusidic acid (Fusidate) a bacteriostatic antibiotic produced from the Fusidium coccineum fungus, belongs to the class of steroids. Fusidic acid has no corticosteroid effects. Fusidic acid inhibits the growth of bacteria by preventing the release of translation elongation factor G (EF-G) from the ribosome. Fusidic acid holds promise for research in anticancer and anti-infective applications..

In Vitro

Fusidic acid (100-200 μM, 72 h) primarily inhibits the proliferation of breast cancer (MCF-7, MDA-MB-231), thyroid cancer (8505C, TPC1), and cervical cancer (Caski, HeLa) cells through cell cycle arrest rather than apoptosis^[3].
Fusidic acid (0.01-100 × MIC, 24 h) exhibits stable intracellular antibacterial activity against methicillin-sensitive Staphylococcus aureus and methicillin-resistant Staphylococcus aureus in THP-1 cells, with potency comparable to Clindamycin (HY-B1455) and Linezolid (HY-10394). MIC at pH 7.4 was 0.25 mg/L, whereas MIC at pH 5.5 decreased to 0.01 mg/L^[4].
Fusidic acid (125 mg/L, 30 min) demonstrates enhanced antibacterial activity against methicillin-sensitive Staphylococcus aureus and significantly increased intracellular accumulation under acidic conditions (pH 5.5)^[4].

Stock Solution Working Solution

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 (4.84 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (4.84 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
