Background
Paederia foetida L. (Rubiaceae) is an edible plant widely distributed in India, Japan, Malaysia, and other Asian countries. This study investigates the enzyme inhibition and of P. foetida twig extracts obtained from two different locations namely Johor (PFJ) and Pahang (PFP) and its chemical constituents.
Methods
The isolation of phytoconstituents using column chromatography methods and in silico study of isolated compound with receptor (α-glucosidase and α-amylase) was carried out using molecular docking.
Results
The IC50 of α-glucosidase and α-amylase inhibition activity of the PFJ chloroform extract were 245.6 ± 0.01 and 9.595 ± 0.01 µg/mL, respectively. The IC50 of α-glucosidase and α-alpha amylase inhibition activity of PFP chloroform extract were 2457.2 ± 0.01 and 14.83 ± 0.05 µg/mL, respectively. Separation of PFP chloroform extract afforded ergost-5-en-3-ol (1), stigmasterol (2), γ-sitosterol (3) and scopoletin (4) meanwhile PFJ chloroform extract gave (2) and (4). Scopoletin was isolated for the first time from this species. In silico molecular interaction study between scopoletin and α-glucosidase and α-amylase showed that α-glucosidase-scopoletin inhibitor complex had better binding affinity with less energy value (-5.4 kcal/mol) than α-amylase-scopoletin inhibitor complex (-4.9 kcal/mol).
Conclusion
PFJ chloroform extract showed potent inhibitory activity toward α-glucosidase. The in silico assessment of scopoletin as antidiabetic agent indicated that α-glucosidase-scopoletin complex has good stability with binding affinity of -5.4 kcal/mol. P. foetida can be considered as potential resources for natural herbal antidiabetic drugs which can serve as alternative to synthetic oral hypoglycemic drugs with minimum side effects.
