Alkaloidlike
Alkaloidlike is a descriptive term used in chemistry and pharmacology to refer to compounds that resemble alkaloids in structural features or pharmacological behavior, without necessarily being classified as true alkaloids. Alkaloids are a broad group of nitrogen-containing, usually basic organic compounds of natural origin that often have pronounced physiological effects in humans and other animals. Alkaloidlike molecules may share key traits such as nitrogen-containing heterocycles, basic amines, and polycyclic or aromatic frameworks that enable interaction with biological targets in ways characteristic of alkaloids.
The term is primarily used as a descriptive label rather than a formal classification. Compounds described
Common structural motifs associated with alkaloidlike candidates include nitrogen-containing heterocycles such as piperidine, pyridine, indole, isoquinoline,
