Benzazepines Derivatives: Synthetic Strategy, Structural-Activity Relationships, and Medical Potential as Dopamine...

Benzazepine derivatives make up a generalized group of nitrogen-bearing heterocycles, which have a wide range. pharmacological range, such as dopaminergic and serotonergic, analgesia, antihypertensive, and anticancer properties. Tetrahydro-3-benzazepine scaffolds are the most preferentially interacting ones among them, which have dopaminergic and serotonergic receptors, in particular, D2/D3- and 5-HT2A-, 5-HT2C-, and 5-HT2B-receptors. They are valuable templates to discover neuropsychiatric drugs, because they belong to the 5-HT6 class. This review systematically summarizes and contrasts the classical and contemporary synthetic methods, such as Pd-catalyzed intramolecular. Heck cyclization, Schmidt and Beckmann rearrangements, and ring-closing metathesis. Particular attention is given to organizing structure-activity relations (SAR), choosing receptors, and physicochemical determinants of ligand efficacy. Mechanistic and computational knowledge is also summarized to direct a rational scaffold. optimization. In general, this discussion demonstrates benzazepines as central nervous system privileged pharmacophores. system-active agents and suggests structure-directed approaches to defining the next-generation dopaminergic and/or strategies. serotonergic modulators.
