Journal ArticleDOI
Coumarins and bicoumarin from Ferula sumbul: anti-HIV activity and inhibition of cytokine release.
Ping Zhou,Yoshihisa Takaishi,Hong-Quan Duan,Bei Chen,Gisho Honda,Michiho Itoh,Yoshio Takeda,Olimjon K. Kodzhimatov,Kuo Hsing Lee +8 more
TL;DR: The methanol extract of the dried roots of Ferula sumbul afforded two furanocoumarin esters and some of the isolated compounds showed anti-HIV activity and very weak inhibition of cytokine release.
Journal ArticleDOI
Sesquiterpenoids from Ferula kuhistanica
Bei Chen,Rie Teranishi,Kazuyoshi Kawazoe,Yoshihisa Takaishi,Gisho Honda,Michiho Itoh,Yoshio Takeda,Olimjon K. Kodzhimatov +7 more
TL;DR: Methanol extracts of the air-dried roots and stems of Ferula kuhistaniica afforded seven daucane-type sesquiterpenes, called kuhistanicaol A-G, together with 13 known daucanes esters, established on the basis of spectroscopic evidence and the results of chemical reactions.
Journal ArticleDOI
Sesquiterpene phenylpropanoid and sesquiterpene chromone derivatives from Ferula pallida.
Bao-Ning Su,Yoshihisa Takaishi,Gisho Honda,Michiho Itoh,Yoshio Takeda,Olimjon K. Kodzhimatov,Ozodbek Ashurmetov +6 more
TL;DR: Four novel compounds-two sesquiterpene phenylpropanoid derivatives, pallidones G and H, and two sesQuiterPene chromone derivatives, Pallidones I and J- have been isolated from the roots of Ferula pallida.
Journal ArticleDOI
Sesquiterpene coumarins and related derivatives from Ferula pallida.
Bao-Ning Su,Yoshihisa Takaishi,Gisho Honda,Michiho Itoh,Yoshio Takeda,Olimjon K. Kodzhimatov,Ozodbek Ashurmetov +6 more
TL;DR: Six new compounds-two sesquiterpene coumarins, pallidones A and B (1, 2), and four related derivatives, pallids C-F (3-6), as well as two known sesQuiterpenes coumarin, feselol (7) and conferol (8), have been isolated from the EtOAc extracts of the roots of Ferula pallida.
Journal ArticleDOI
Macrophyllols A and B, two unusual novel sesquiterpene and monoterpene dimers from the bark of Inula macrophylla.
Bao-Ning Su,Yoshihisa Takaishi,Motoo Tori,Shigeru Takaoka,Gisho Honda,Michiho Itoh,Yoshio Takeda,Olimjon K. Kodzhimatov,Ozodbek Ashurmetov +8 more
TL;DR: Two novel sesquiterpene and monoterpene dimers, macrophyllols A and B, were isolated from the bark of Inula macrophylla on the basis of spectral evidence as well as chemical transformation.
