Description
Overview of Osthole 98%
Osthole (7-methoxy-8-(3-methyl-2-butenyl)-2H-chromen-2-one) is a naturally occurring prenylated coumarin compound commonly isolated from the mature fruit of Cnidium monnieri and other plant species, including Angelica, Archangelica, and Citrus. It belongs to the broader family of benzopyran-derived coumarins, a class of phytochemicals widely investigated for their biochemical activity in experimental systems.
Due to its defined chemical structure and occurrence in several medicinal plants, Osthole is utilized as a standard compound for studies in pharmacology and natural product chemistry. Not FDA approved. It is solely designed for use in laboratory research, not for human or animal consumption.

Mechanism of Action
Experimental studies indicate that osthole interacts with several intracellular signaling pathways. These interactions are examined primarily in cell-based assays and preclinical research models.
Modulation of Cyclic Nucleotide Signaling
Osthole has been reported to influence cyclic nucleotide pathways, including cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). These second messengers regulate kinase activity and transcriptional responses associated with cellular signaling networks.
Regulation of Kinase Signaling Pathways
Osthole has been observed to influence kinase signaling cascades, including
- Mitogen-activated protein kinase (MAPK) pathways
- PI3K/Akt signaling networks
These pathways play key roles in regulating cellular stress responses, apoptosis-related proteins, and transcription factors studied in molecular biology research.
Interaction with Inflammatory Enzyme Systems
Cell culture experiments have shown that osthole may modulate the activity of enzymes associated with inflammatory signaling pathways, including:
- Cyclooxygenase (COX) enzymes
- 5-Lipoxygenase (5-LO)
- Inducible nitric oxide synthase (iNOS)
These enzymes are commonly examined in biochemical studies investigating inflammatory mediator production and immune signaling pathways.
Calcium Channel and Ion Channel Modulation
Some electrophysiological research suggests that osthole may influence voltage-dependent calcium channels and related ion transport mechanisms. These interactions are studied in neuronal cell models to examine regulation of cellular excitability and signal transduction.
