Guaiol is a sesquiterpenoid alcohol with oral activity found in various traditional Chinese medicines, exhibiting biological activities such as anti-proliferative, autophagy-promoting, insecticidal, anti-anxiety, anti-inflammatory, diuretic, and blood pressure-lowering effects. Guaiol induces apoptosis in non-small cell lung cancer cells by regulating the stability of RAD51 through autophagy modulation. Guaiol can also act directly on parasites, inhibiting their growth by affecting the kinetoplast, mitochondrial matrix and plasma membrane of the promastigotes. Guaiol kills amastigotes at an IC₅₀ of 0.01 µg/mL. Guaiol can be used in research related to cancer, infections, cardiovascular diseases, and inflammatory conditions^[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 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (11.24 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.

Working Solution

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.

Protocol 1

Add each solvent one by one: 50% PEG300 50% Saline

Solubility: 1 mg/mL (4.50 mM); Suspended solution; Need ultrasonic

Help & FAQs

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.
