Polyoxometalates active against tumors, viruses, and bacteria

Area of Science:

• Inorganic Chemistry
• Materials Science
• Medicinal Chemistry

Background:

• Polyoxometalates (PMs) are discrete metal-oxide cluster anions with high water solubility and significant photochemical and electrochemical activity.
• PMs exhibit remarkable structural diversity in size, metal composition, symmetry, and charge, influenced by environmental factors like pH and concentration.
• Their unique physicochemical properties have led to investigations into their medical applications.

Purpose of the Study:

• To review the development of Polyoxometalates (PMs) for medical applications, focusing on their antitumoral, antiviral, and antibacterial activities.
• To highlight specific PM compounds licensed for clinical use in chemotherapy and infectious disease treatment.
• To discuss the chemotherapeutic mechanisms and potential of PMs as novel inorganic medicines.

Main Methods:

• Literature review of research on Polyoxometalates (PMs) and their applications in medicine.
• Analysis of structural properties and environmental influences on PM conformation.
• Compilation of data on licensed PM candidates for various diseases, including specific compound names and their targets.

Main Results:

• Several PMs have demonstrated significant antitumoral activity against solid tumors, with specific examples licensed for human gastric and pancreatic cancers.
• PMs show efficacy against a range of DNA and RNA viruses, including HSV, HIV, influenza, and SARS.
• Certain PMs are effective against drug-resistant bacteria such as MRSA and VRSA, offering new therapeutic options.

Conclusions:

• Polyoxometalates (PMs) represent a promising class of inorganic compounds for novel therapeutic agents.
• The structural versatility and tunable properties of PMs enable targeted applications in oncology, virology, and infectious disease treatment.
• Further research into the chemotherapeutic clarification of PMs will advance their role in modern medicine.
