Tryptanthrin is an indole quinazoline that could be an alkaloid from indigo-bearing plants. Tryptanthrin is a potent and orally active cellular Leukotriene (LT) biosynthesis inhibitor. Tryptanthrin has anticancer activity. Tryptanthrin suppresses the expression levels of NOS1, COX-2, and NF-κB and regulates the expression levels of IL-2, IL-10, and TNF-α.

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: 0.71 mg/mL (2.86 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 0.71 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (7.1 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% (20% SBE-β-CD in Saline)

Solubility: 0.67 mg/mL (2.70 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 0.67 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.7 mg/mL) to 900 μL 20% SBE-β-CD in Saline, 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.
