Lead compounds are chemical substances that show promising biological activity and serve as starting points for drug development. They often exhibit the desired effects against specific diseases or conditions, making them valuable in the search for new medications. Researchers analyze these compounds to understand their mechanisms and optimize their properties. Once a lead compound is identified, it undergoes further testing and modification to improve its efficacy, safety, and stability. This process may involve synthesizing analogs or derivatives to enhance performance. Ultimately, the goal is to develop a viable drug candidate that can advance to clinical trials and potentially reach the market.
