20554-84-1 Usage
Description
Parthenolide is an allergen in feverfew (Tanacetum
parthenarium).
Chemical Properties
White solid
Uses
Different sources of media describe the Uses of 20554-84-1 differently. You can refer to the following data:
1. Antiinflammatory;MAP kinase inhibitor
2. Parthenolide is a sesquiterpene lactone from the plant feverfew (T. parthenium). It inhibits the growth of the promastigote form of L. amazonensis (IC50 = 3.6 μg/ml). Parthenolide also induces apoptosis in cancer cells, at least in part by inhibiting NF-κB- and STAT-mediated anti-apoptotic gene transcription. This compound has also been shown to block inflammation by inhibiting signaling through NF-κB. Inhibition of NF-κB by parthenolide can be achieved by direct binding of the pattern recognition receptor NOD2 by parthenolide.
3. Parthenolide is an anti-inflammatory agent used in the treatment of ischemic injury. Also acts as an anti-tumor and anti0leukemia agent targetting acute myeloid leukemia.
Definition
ChEBI: A sesquiterpene lactone and active principle of Feverfew (Tanacetum parthenium).
General Description
This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG
Biological Activity
The active principle of feverfew (Chrysanthemum parthenium), widely used as a herbal remedy for arthritis and migraine and as a febrifuge. Parthenolide is antisecretory, anti-inflammatory, spasmolytic and inhibits the release of 5-HT from blood platelets. Also inhibits generation of leukotriene B 4 and thromboxane B 2 .
Biochem/physiol Actions
Parthenolide is a sesquiterpene lactone present abundantly in the leaves and flowers of Tanacetum parthenium. It exhibits anti-cancer properties for the treatment of invasive cancers. Parthenolide exhibits therapeutic effects against inflammation and migraine. It plays a role in signal transduction and activation of transcription (STAT)-inhibition-mediated transcriptional repression of pro-apoptotic genes.
Contact allergens
Parthenolide is a sesquiterpene lactone found Asteraceae-
Compositae such as feverfew (Tanacetum parthenium
Schultz-Bip.) or congress grass (Parthenium hysterophorus
L.).

Check Digit Verification of cas no
The CAS Registry Mumber 20554-84-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,5 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20554-84:
(7*2)+(6*0)+(5*5)+(4*5)+(3*4)+(2*8)+(1*4)=91
91 % 10 = 1
So 20554-84-1 is a valid CAS Registry Number.
