“…392 Suntharalingam and co-workers developed gold(I) complexes bearing nonsteroidal anti-inflammatory drugs (NSAID) to target breast cancer stem-cells (Figure 24). 393 Lead complex containing indomethacin moiety showed greater inhibitory effect (80-fold) against breast CSCs than the bulk breast cancer cell population. An inquiry into the mechanism of action of the lead complex revealed cytoplasmic accumulation of the complex, inhibition of cyclooxygenase-2 (COX-2) and increased levels of intracellular ROS.…”

“…This work further demonstrates that targeting CSCs is an effective strategy for cancer treatment. 393 Sun et al also reported a gold(III) meso-tetraphenylporphyrin complex that inhibit formation of spheroids from single cell suspension in U-87 glioblastoma cancer cells. The porphyrin complex demonstrated potent in vitro and in vivo toxicity in a panel of cancer cells and high physiological stability in glutathione and serum albumen.…”

“…In vivo efficacy for the gold(I)-indomethacin complex was demonstrated in 4T1 tumor-bearing mice; tumor was significantly reduced without affecting mice body weight. This work further demonstrates that targeting CSCs is an effective strategy for cancer treatment …”

The gold drugs, gold sodium thiomalate (Myocrisin), aurothioglucose (Solganal), and the orally administered auranofin (Ridaura), are utilized in modern medicine for the treatment of inflammatory arthritis including rheumatoid and juvenile arthritis; however, new gold agents have been slow to enter the clinic. Repurposing of auranofin in different disease indications such as cancer, parasitic, and microbial infections in the clinic has provided impetus for the development of new gold complexes for biomedical applications based on unique mechanistic insights differentiated from auranofin. Various chemical methods for the preparation of physiologically stable gold complexes and associated mechanisms have been explored in biomedicine such as therapeutics or chemical probes. In this Review, we discuss the chemistry of next generation gold drugs, which encompasses oxidation states, geometry, ligands, coordination, and organometallic compounds for infectious diseases, cancer, inflammation, and as tools for chemical biology via gold–protein interactions. We will focus on the development of gold agents in biomedicine within the past decade. The Review provides readers with an accessible overview of the utility, development, and mechanism of action of gold-based small molecules to establish context and basis for the thriving resurgence of gold in medicine.
