Structure and function of "metalloantibiotics".

Area of Science:

• Medicinal Chemistry
• Biochemistry
• Pharmacology

Background:

• Most antibiotics do not require metal ions for biological activity.
• However, some antibiotics, like bleomycin (BLM), streptonigrin (SN), and bacitracin, are dependent on coordinated metal ions.
• These metal ions are crucial for maintaining the structural integrity and functional efficacy of these specific antibiotics.

Purpose of the Study:

• To review the class of antibiotics known as metalloantibiotics.
• To explore the role of metal ions in antibiotic structure and function.
• To discuss the interactions of metalloantibiotics with biomolecules and their resulting bioactivities.

Main Methods:

• Literature review of metalloantibiotics, including microbial-originated compounds and synthetic derivatives.
• Analysis of the structural and functional impact of metal ion coordination.
• Examination of interactions with biomolecules such as DNA, RNA, proteins, receptors, and lipids.

Main Results:

• Metalloantibiotics necessitate metal ions for proper biological function.
• Metal ion removal alters the structure and/or function of these antibiotics.
• Metalloantibiotics exhibit diverse bioactivities, including antibacterial, antiviral, and anti-neoplastic effects, through interactions with various biomolecules.

Conclusions:

• Metalloantibiotics represent a distinct class of therapeutic agents reliant on metal ion coordination.
• Their ability to interact with diverse biomolecules underlies their broad spectrum of bioactivities.
• The study of metalloantibiotics and their derivatives offers potential for developing novel therapeutic agents.
