ADB-FUBIATA, also known as AD-18 or FUB-ACADB, emerged as a synthetic cannabinoid compound in 2021. It shares structural similarities with the older combination ADB-FUBICA, with a notable distinction – an extended amide linker group by adding a methylene bridge. This compound found its way into the market as an ingredient in grey-market synthetic cannabis blends. This shift was prompted by changes in Chinese legislation, which introduced comprehensive controls on various classes of synthetic cannabinoids but did not encompass compounds with the specific linker group extension.
ADB-FUBIATA exhibits significantly lower affinity for cannabinoid receptors than ADB-FUBICA, boasting an EC50 of only 635 nM at CB1. However, it still acts as a full agonist at the CB1 receptor while demonstrating negligible activity at CB2.
