In the realm of anti-infective agents, a diverse array of antimicrobials serves as powerful tools in the fight against pathogenic invaders. Antimicrobial peptides, a natural component of the immune system, exhibit broad-spectrum activity against various microorganisms. These peptides disrupt microbial membranes, preventing their survival and replication. Furthermore, antiviral agents specifically target viruses, impeding their ability to infect host cells. The development of antiretroviral drugs has been a game-changer in managing HIV/AIDS, showcasing the potential of antiviral interventions. Antifungal agents, combating fungal infections, and antiparasitic medications addressing parasitic diseases contribute to the multifaceted approach in treating infectious conditions. As research progresses, the quest for novel anti-infective agents intensifies, aiming to stay one step ahead of evolving microbial threats and ensuring effective responses to a broad spectrum of infectious diseases.
