Potential Anticancer Activity of Auranofin.

Area of Science:

• Oncology
• Pharmacology
• Biochemistry

Background:

• Gold compounds have historical medical applications.
• Auranofin, an oral therapy for rheumatoid arthritis, is now rarely used due to newer treatments.
• Despite decreased clinical use, auranofin is being studied for novel applications, including cancer therapy.

Purpose of the Study:

• To review the current understanding of auranofin's potential as an anticancer agent.
• To explore the mechanism of action of auranofin in cancer treatment.
• To highlight auranofin's potential against various human diseases.

Main Methods:

• The review summarizes existing research on auranofin.
• It focuses on auranofin's inhibition of thioredoxin reductase (TrxR).
• The review discusses the role of the thioredoxin (Trx) system in cancer.

Main Results:

• Auranofin inhibits TrxR, a key enzyme in the Trx system.
• TrxR inhibition increases cellular oxidative stress and induces apoptosis in cancer cells.
• Overexpression of TrxR is linked to aggressive tumor progression and poor survival in several cancers.

Conclusions:

• The Trx system presents a promising target for novel cancer treatments.
• Auranofin, as a TrxR inhibitor, demonstrates potential as a potent anticancer agent.
• Further research into auranofin could lead to new therapeutic strategies for cancer and other diseases.
