Synthesis of α-mangostin derivatives at C3 and C6 positions and their inhibitory activity against phosphodiesterase 4
-mangostin as the lead compound, and using the primary methods including alkylation and hydrolysis reactions for modifying C-3
and C-6 positions, eighteen novel derivatives with different chain length of carboxylic acid ester, carboxylic acid, and amide substituents in the C-3, C-6 phenolic hydroxyl group of
α
-mangostin were designed and synthesized. The
in vitro
evaluation of these compounds' ability to inhibit PDE4 was conducted using the [³H] liquid scintillation counting technique. The experimental results showed that five compound (
2a
-
6a
) had the stronger inhibitory activity on PDE4 than
α
-mangostin. Among them, carboxylic acid derivative of seven carbon chain lengths
5a
exhibited the best potential PDE4 inhibitory activity with the IC
