α‐Mangostin has been reported to possess a broad range of pharmacological effects including potent cholinesterase inhibition, but the development of α‐mangostin as a potential lead compound is impeded by its toxicity. The present study investigated the impact of simplestructural modification of α‐mangostin on its cholinesterase inhibitory activities and toxicity toward neuroblastoma and liver cancer
their cytotoxicity against a panel of five humancancercelllines (HL-60, SMMC-7721, A-549, MCF-7 and SW480) using MTT assays. Most of them showed cytotoxicity and most of all, compounds 1a and 2h showed the highest cytotoxicpotency by HL-60 cancercelllines with IC50 values of 5.96 μM and 6.90 μM respectively; compound 3e showed the highest cytotoxicpotency against SMMC-7221 cancercell line with
