Phellopterin is natural product of the coumarin class extracted from Angelica dahurica. Phellopterin exerts anti-inflammatory effects both in vitro and in vivo, and the potential mechanism depends on SIRT1. hellopterin showed therapeutic benefits in the healing process by attenuating chronic inflammation and promoting re-epithelialization, along with SIRT1 upregulation and ICAM-1 downregulation. However, inhibiting SIRT1 reversed its proliferative and anti-inflammatory effects. It can reduce TNF-alpha-induced VCAM-1 expression through regulation of the Akt and PKC pathway, which contributes to inhibit the adhesion of monocytes to endothelium.
| Toxicity/Toxicokinetics |
Toxicity Summary
Many furanocoumarins act through mechanisms based on their ability to form photoadducts with DNA and other cellular components, such as RNA, proteins, and membrane proteins, including phospholipases A2 and C, calcium-dependent and cAMP-dependent protein kinases, and epidermal growth factor. Furanocoumarins can intercalate between DNA base pairs and form cycloadducts upon UVA irradiation. Furthermore, furanocoumarins are also inhibitors of insect cytochrome P450. They strongly inhibit the in vitro binding of [3H]diazepam to benzodiazepine receptors in the central nervous system. (L579) |

| Additional Infomation |
Psoralen belongs to the psoralen class of compounds. It has been reported to be found in Melicope triphylla, Komarovia anisosperma, and other organisms with relevant data. It is a naturally occurring furanocoumarin found in the roots of Angelica dahurica and Seseli elatum (L579). Furanocoumarins are phototoxic and photocarcinogenic. They can intercalate into DNA and photochemically induce mutations. Furanocoumarins are phytoalexins, present in varying amounts in many vegetables and fruits, particularly citrus fruits. The levels of furanocoumarins in our daily diet are usually far below the levels that cause significant acute phototoxicity, but they do cause pharmacologically significant drug interactions. Some furanocoumarins exhibit particularly strong activity against cytochrome P450 enzymes. For example, in humans, bergamotin and dihydroxybergamotin are the culprits of the "grapefruit juice effect," and these furanocoumarins can affect the metabolism of certain drugs.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.32 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |

| 5 mM | 0.6660 mL | 3.3299 mL | 6.6598 mL | |
| 10 mM | 0.3330 mL | 1.6649 mL | 3.3299 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
