Antibiotics are antimicrobial agents that selectively inhibit the growth of or kill bacteria, making them a critical class of pharmaceutical compounds in medicine. They function by interfering with fundamental metabolic or structural processes unique to microbial life, such as disrupting the bacterial cell wall synthesis or inhibiting essential enzyme functions. The efficacy of antibiotics relies on the ability of the drug to target bacterial processes without significantly harming the host's own cells. However, the sustained use and misuse of these agents have led to the global biological challenge of antibiotic resistance, a process wherein bacteria evolve genetic mechanisms that neutralize the drug's action, necessitating the continuous discovery of novel therapeutic compounds.
