Viral and microbial surface and intracellular biomolecules

The term Viral and microbial surface and intracellular biomolecules refers to a broad and heterogeneous collection of molecular entities rather than a single therapeutic target. This category encompasses structural proteins, enzymes, nucleic acids, and lipids essential for the survival and replication of pathogens such as viruses, bacteria, and fungi (NIH, 2023). Surface biomolecules, such as viral glycoproteins or bacterial peptidoglycans, often serve as primary targets for vaccines and neutralizing antibodies, while intracellular components like polymerases and proteases are frequent targets for small-molecule anti-infectives (Nature Reviews Drug Discovery, 2020). Because this term lacks specificity regarding the organism or the molecular class, it is considered a descriptive category for various drug targets rather than a distinct receptor or enzyme. In drug development, researchers must identify specific, conserved biomolecules within this group to ensure therapeutic efficacy and minimize cross-reactivity with human host proteins.
