Recent Studies on Serotonin 5-HT2A Receptor Antagonists in Medicinal Chemistry: A Last Decades Survey

In the last decades, much attention has been paid to the functioning of receptors to understand better how they work with various chemical motifs. Among different families, G-proteincoupled receptor (GPCR) families have drawn much attention in the twenty-first century. They are the most prominent signal transducer across the cell membrane, comprising thousand-odd proteins. One of the members of GPCRs is the serotonin 2A (5-HT2A) receptor, which has been associated with complex etiological mental illnesses. In this survey, we collected data on 5-HT2A, i.e., the role of 5- HT2A receptors in human and animal analogy, various binding site functionalities, advanced effects, and synthetic aspects.
