8-Deoxygartanin 是山竹果中的异戊烯化呫吨酮。它是丁基胆碱酯酶选择性抑制剂，对阿尔茨海默病 (AD) 具有多功能活性，可能是有希望治疗 AD 的化合物。

8-Deoxygartanin is a butyrylcholinesterase (BChE) selective inhibitor, it exhibits significant inhibition of self-induced α2-amyloid (Aα2) aggregation, it has multifunctional activities against Alzheimer's disease (AD) and could be promising compounds for the therapy of AD.

The present study investigated acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities of G. mangostana extract and its chemical constituents using Ellman's colorimetric method. Cholinesterase inhibitory-guided approach led to identification of six bioactive prenylated xanthones showing moderate to potent cholinesterases inhibition with IC50 values of lower than 20.5 μM. The most potent inhibitor of AChE was garcinone C while γ-mangostin was the most potent inhibitor of BChE with IC50 values of 1.24 and 1.78 μM, respectively. Among the xanthones, mangostanol, 3-isomangostin, garcinone C and α±-mangostin are AChE selective inhibitors, 8-Deoxygartanin is a BChE selective inhibitor while γ-mangostin is a dual inhibitor. Preliminary structure-activity relationship suggests the importance of the C-8 prenyl and C-7 hydroxy groups for good AChE and BChE inhibitory activities. The enzyme kinetic studies indicate that both α±-mangostin and garcinone C are mixed-mode inhibitors, while γ-mangostin is a non-competitive inhibitor of AChE. In contrast, both γ-mangostin and garcinone C are uncompetitive inhibitors, while α±-mangostin is a mixed-mode inhibitor of BChE[1]
