Effects of Coumarins from Roots of Paramignya scandens (Griff.) Craib on LPS-induced IL-1β and IL-10 Cytokine Production in RAW 264.7 Macrophages
(2024) In Natural Product Sciences 30(1). p.30-38- Abstract
Based on our previous study, we evaluated the modulatory effects on LPS-induced IL-1β and IL-10 cytokine production in RAW 264.7 macrophages of several medicinal herbs, including P. scandens. The results showed that P. scandens extract showed significant effects on LPS-induced IL-1β and IL-10 cytokine production in RAW 264.7 macrophages. Therefore, in the current research, we focused on the P. scandens sample. Cytokine production effects bioassay-guided isolation of ethyl acetate fraction of 70% ethanol extract from roots of Paramignya scandens (XL) obtained seven coumarins (1–7). Their chemical structures were identified using spectroscopic methods (NMR and MS) and compared with those previously published data to be xanthyletin (1),... (More)

The results showed that P. scandens extract showed significant effects on LPS-induced IL-1β and IL-10 cytokine production in RAW 264.7 macrophages. Therefore, in the current research, we focused on the P. scandens sample. Cytokine production effects bioassay-guided isolation of ethyl acetate fraction of 70% ethanol extract from roots of Paramignya scandens (XL) obtained seven coumarins (1–7). Their chemical structures were identified using spectroscopic methods (NMR and MS) and compared with those previously published data to be xanthyletin (1), luvangetin (2), clausenidin (3), nordentatin (4), dentatin (5), clausarin (6), and anisocoumarin E (7). This study represents the first report on the presence of compounds 3, 6, and 7 in the Paramignya genus and compounds 1 and 2 in XL. All isolates (1–7) exhibited significant inhibition of LPS-induced interleukin (IL)-1β production compared to the LPS 5 ng/mL control group, with IL-1β concentrations ranging from 42.77 to 69.76 pg/mL. Additionally, the IL-10 production induced by compounds 1‒7 in LPS-stimulated RAW 264.7 macrophages ranged from 175.98 to 321.56 pg/mL, demonstrating a marked increase as compared to the LPS 5 ng/mL control group. The stimulatory effect on IL-10 production and inhibitory effect on IL-1β production of compounds 1, 2, and 6 gradually increased with the test concentration in both RAW 264.7 macrophages and LPS-induced RAW 264.7 macrophages. Compounds 1, 2, and 6 inhibited IL-1β production in LPS-induced RAW 264.7 macrophages with IC50 values of 10.70 ± 1.18 µM, 8.57 ± 1.05 µM, and 17.43 ± 1.05 µM, respectively. These findings highlight the potential of all the compounds derived from P. scandens roots in inducing IL-1β and IL-10 cytokines activity in LPS-stimulated RAW 264.7 macrophages. The results contributed to expanding the knowledge of the chemistry and bioactivities of P. scandens and provided valuable data for future investigations on this species.
