 5-HT2C receptor agonists are attractive drug targets that have potential use in the treatment of a number of conditions including obesity, psychiatric disorders, sexual dysfunction and urinary incontinence.The 5-HT2C receptors are one of three subtypes that belong to the serotonin 5-HT2 receptor subfamily along with 5-HT2A and 5-HT2B receptors.The development of 5-HT2C agonists has been a major obstacle, because of severe side effects due to a lack of selectivity over 5-HT2A and 5-HT2B receptors.
