Quercetin as a JAK-STAT inhibitor: a potential role in solid tumors and neurodegenerative diseases

Area of Science:

• Molecular Biology
• Immunology
• Pharmacology
• Oncology
• Neuroscience

Background:

• The JAK-STAT pathway regulates critical cellular processes like growth, proliferation, differentiation, apoptosis, and inflammation.
• Dysregulation of the JAK-STAT pathway is implicated in cancer progression and neurodegenerative diseases.
• Current JAK-STAT targeted therapies often show limited long-term efficacy due to pathway complexity and crosstalk.

Purpose of the Study:

• To review the pharmacological effects of quercetin on the JAK-STAT signaling pathway.
• To explore quercetin's potential in managing solid tumors and neurodegenerative diseases via JAK-STAT inhibition.

Main Methods:

• Literature review of studies investigating quercetin's interaction with the JAK-STAT pathway.
• Analysis of research on quercetin's anti-inflammatory, antitumor, and neuroprotective activities.

Main Results:

• Quercetin demonstrates significant inhibitory effects on the JAK-STAT pathway through various mechanisms.
• Quercetin exhibits potent anti-inflammatory and antitumor activities.
• Quercetin shows promise in controlling neurodegenerative conditions.

Conclusions:

• Quercetin represents a promising natural compound for targeting the JAK-STAT pathway.
• Its multifaceted pharmacological effects suggest potential therapeutic applications in oncology and neurodegenerative disorders.
