Aurothioglucose: Uses, Benefits, and Side Effects

Introduction

Aurothioglucose is a gold-containing chemical compound with the formula C ₆H ₁₁AuO ₅S, derived from glucose. It was formerly used in the treatment of rheumatoid arthritis, particularly in early active adult and juvenile types unresponsive to conventional therapy.

Chemical Properties

Aurothioglucose, also known as gold thioglucose, is a derivative of glucose with the molecular structure C ₆H ₁₁AuO ₅S. It is a gold compound and Aurothioglucose” target=”_blank”>PKCiota-Par6 inhibitor with the PubChem CID 454937.

Mechanism of Action

Aurothioglucose acts as a potent active-site inhibitor of specific enzymes like PKCiota-Par6 and TrxR1 (thioredoxin reductase 1). It interacts within biological systems by inhibiting these enzymes, leading to its therapeutic effects in conditions like rheumatoid arthritis.

Medical Uses

Aurothioglucose is indicated for use in rheumatoid arthritis, particularly as an adjunctive treatment for early active adult and juvenile rheumatoid arthritis unresponsive to conventional therapy. It may be chosen over other treatments in specific situations based on patient factors and disease severity.

Clinical Applications

The recommended dosage of Aurothioglucose for adults is 50 mg intramuscularly once weekly, with a maximum dose of 50 mg. For children, the dosage is adjusted based on weight. It is administered as an injectable solution, typically in a clinical setting under medical supervision.

Side Effects and Safety

Common side effects of Aurothioglucose include injection site reactions, while rare but serious side effects may involve gold-induced toxicity. The overall safety profile is considered acceptable, with most patients tolerating the treatment well. Close monitoring is essential to detect and manage any adverse effects promptly.
