Pyranocoumarins from Glehnia littoralis inhibit the LPS-induced NO production in macrophage RAW 264.7 cells

New coumarins from the roots of Angelica dahurica var. formosana cv. Chuanbaizhi and their inhibition on NO production in LPS-activated RAW264.7 cells

“…Previous studies showed that overproduction of NO by NOS was responsible for inflammation. The effects of various coumarins on NO production in LPS-activated RAW 264.7 macrophage cells were reported [19][20][21][22][23][24]. As part of our project to find novel structures with inhibitory activity on overproduction of NO [25][26][27], two new and six known coumarins were isolated from RADFC.…”
