Upjohn first created U-47700, an opioid family analgesic, about 40 years ago. It was create using AH-7921, a similar opioid. U-47700 has never undergone rigorous testing on either humans or animals, despite being crucial in the development of this class of opioid compounds.

The opioid AH-7921’s structural isomer, U-47700, is the product of extensive research into the quantitative structure-activity relationship of the scaffold. Upjohn registered more than a dozen patents on related compounds, each one optimizing a different moiety, in an effort to identify the key moieties that provided the greatest activity. Eventually, they found that U-47700 was the most active of these compounds.

Selective kappa-opioid receptor ligands U-50488, U-51754 (with a single methylene spacer variation), and U-69,593 all have extremely similar structural makeups, however U-47700 emerged as the lead molecule. The selective kappa ligands are utilized in research but not for medical purposes. Purchase U-47700 online
