Part, Parthenolide: Click to Expand ⟱
Features:
Parthenolide is a naturally occurring sesquiterpene lactone derived from the medicinal plant feverfew (Tanacetum parthenium).
-Micheliolide (MCL) is converted readily from parthenolide (PTL), and has better stability and solubility than PTL
-Parthenolide is a natural compound used to treat migraines and arthritis and found to act as a potent NF-κB signaling inhibitor.

Main activities include:
-Inhibition of NF-κB Signaling:
-Induction of Oxidative Stress (ROS): oxidative stress can overwhelm the antioxidant defenses of the cancer cells, leading to cellular damage and death
-Parthenolide can interfere with STAT3 signaling, inhibiting the transcription of genes that favor tumor growth and resistance to apoptosis.
-Modulation of the MAPK/ERK Pathway:
-Impact on the JNK Pathway:
-Parthenolide has been shown to target cancer stem cells
TrxR1, thioredoxin reductase 1: Click to Expand ⟱
Source:
Type:
TrxR1 or TXNRD1 (Thioredoxin Reductase 1)
• Many studies have found that an elevated expression of TrxR1 in breast tumors, NSCLC, HCC correlates with increased tumor aggressiveness and a poorer prognosis.
-TrxR1 expression was elevated by >50 fold in FaDu and HeLa cells, and by >20 fold in SCC-1 compared to either MSK-Leuk1 or keratinocytes.

• High TrxR1 levels have been associated with resistance to chemotherapy in some subtypes.
