Analogues in research refer to compounds or substances that are structurally similar to a particular molecule of interest. These analogues may have similar properties or functions as the original molecule, making them valuable tools for studying biological processes, drug development, and other scientific endeavors. By comparing the effects of analogues to the original molecule, researchers can gain insights into the mechanisms of action and potential therapeutic applications. Analogues are commonly used in fields such as medicinal chemistry, pharmacology, and biochemistry.
