BW-723C86, a Common card

The card carries these facts from its Wikipedia article.

• It has anxiolytic effects in animal studies, and is also used for investigating the function of the 5-HT2B receptor in a range of other tissues.
• BW-723C86 is actually a mixed 5-HT2B/5-HT2C agonist, and while it has good selectivity over 5-HT2A and other serotonin receptor subtypes, it is around only 3 times as selective for 2B compared to 2C and so is much less selective than most research ligands, but no superior 5-HT2B agonist was available until the potent and selective 5-HT2B activity of 6-APB was discovered in 2012.
• Highly selective 5-HT2C antagonists are available however, and so a combination of BW-723C86 with a selective 5-HT2C antagonist allows 5-HT2B mediated responses to be studied in isolation.
