Benzazepines

Varenicline, sold under the brand names Chantix and Champix among others, is a medication used for smoking cessation and for the treatment of dry eye syndrome. It is a nicotinic acetylcholine receptor partial agonist. When activated, this receptor leads to the release of dopamine in the nucleus accumbens, the brain's reward center, thereby reducing cravings and withdrawal symptoms with smoking cessation, although less pronounced than a full agonist (e.g. nicotine).

Galantamine is a type of acetylcholinesterase inhibitor. It is an alkaloid extracted from the bulbs and flowers of Galanthus nivalis (common snowdrop), Galanthus caucasicus (Caucasian snowdrop), Galanthus woronowii (Voronov's snowdrop), and other members of the family Amaryllidaceae, such as Narcissus (daffodil), Leucojum aestivum (snowflake), and Lycoris including Lycoris radiata (red spider lily). It can also be produced synthetically.

Lorcaserin, marketed under the brand name Belviq, was a weight-loss drug developed by Arena Pharmaceuticals. It reduces appetite by activating the 5-HT2C serotonin receptor in the hypothalamus, a region of the brain which is known to control appetite. It was approved in 2012, and in 2020 was removed from the market in the United States due to an increased risk of cancer detected in users of Belviq.

Benzazepines are heterocyclic chemical compounds consisting of a benzene ring fused to an azepine ring. There are three different isomers of benzazepine, including 1-benzazepine, 2-benzazepine, and 3-benzazepine. Examples of substituted benzazepine derivatives include:

Rucaparib, sold under the brand name Rubraca, is a PARP inhibitor used as an anti-cancer agent. Rucaparib is a first-in-class pharmaceutical drug targeting the DNA repair enzyme poly-ADP ribose polymerase-1 (PARP-1). It is taken by mouth.

Mozavaptan (INN) is a vasopressin receptor antagonist marketed by Otsuka. In Japan, it was approved in October 2006 for hyponatremia (low blood sodium levels) caused by syndrome of inappropriate antidiuretic hormone (SIADH) due to ADH producing tumors.

Capsazepine is a synthetic antagonist of capsaicin. It is used as a biochemical tool in the study of TRPV ion channels.
