Microbial nucleic acids and nucleotides

Microbial nucleotides and nucleic acids encompass the DNA and RNA molecules that serve as the fundamental genetic material for pathogens, including bacteria, viruses, fungi, and parasites. These molecules are essential for the storage of genetic blueprints and the execution of biological processes such as replication, transcription, and translation, which are required for microbial survival and proliferation (StatPearls, 2023). In pharmacology, they are critical targets for a wide range of antimicrobial agents that exploit structural or enzymatic differences between microbial and host genetic machinery. Some drugs act by directly damaging the nucleic acid structure, such as nitroimidazoles that cause DNA strand breakage, while others are nucleoside or nucleotide analogs that incorporate into growing chains to cause premature termination (NIH, 2022; PubChem, 2024). While these targets provide a basis for selective toxicity, challenges such as the rapid development of resistance through genetic mutations and potential off-target effects on host mitochondrial DNA remain significant considerations in drug development (PubMed, 2021).

Drugs targeting microbial nucleic acids primarily act through direct chemical damage (e.g., strand breakage), intercalation between base pairs to disrupt replication and transcription, or by acting as nucleoside/nucleotide analogs that cause premature chain termination during synthesis (StatPearls, 2023; PubChem, 2024).
