Bioactive spirostane glycosides from Tacca plantaginea.

Numai utilizatorii înregistrați pot traduce articole

Eight new spirostane glycosides, taccaosides E-L (2-7, 11, and 14), along with 7 known spirostane glycosides were isolated from the extract of the whole plants of Tacca plantaginea (Hance) Drenth. Their structures were established on the basis of physical data, spectroscopic analysis (MS, 1D and 2D

New glycosides of the campesterol derivative from the rhizomes of Tacca chantrieri.

In the screening search for NF-κB inhibitory and PPAR transactivational agents from medicinal plants, a methanol extract of the whole plant of Tacca plantaginea and its aqueous fraction showed the significant activities. Bioassay-guided fractionation combined with repeated chromatographic separation

New glycosides from the rhizomes of Tacca chantrieri.

Numai utilizatorii înregistrați pot traduce articole

Five new glycosides, which are classified into two bisdesmosidic pseudofurostanol glycosides (1, 2), two new ergostanol glycosides (3, 4), and a new phenolic glycoside (5), were isolated from the rhizomes of Tacca chantrieri. The structures of 1-5 were determined on the basis of extensive

Taccasubosides A-D, four new steroidal glycosides from Tacca subflabellata.

Numai utilizatorii înregistrați pot traduce articole

By analyzing the steroidal content of fresh whole plants of Tacca subflabellata (Taccaceae), we isolated one sapogenin and eight glycosides with four kinds of steroidal skeletons including four new glycosides, named taccasubosides A-D (1-4), together with five known compounds. Among them, compound 1

Numerous clinically valuable medicines, including anticancer drugs, have been developed from biologically active natural compounds and their structurally related derivatives. This review discusses novel natural compounds with promising biological activities and those with novel chemical structures.

Plantagiolides K-N, three new withanolides and one withanolide glucoside from Tacca plantaginea.

Numai utilizatorii înregistrați pot traduce articole

Phytochemical investigation of the whole plants of Tacca plantaginea led to the isolation of 3 new withanolides and one new withanolide glucoside, named plantagiolides K-N (1-4), together with one known withanolide, 4 known withanolide glucosides, and 2 known taccalonolides. Their structures were

Three new steroid saponins (3beta,25R)-spirost-5-en-3-yl 6-deoxy-alpha-L-mannopyranosyl-(1-->2)-[beta-D-glucopyranosyl-(1-->4)-6-deoxy-alpha-L-mannopyranosyl-(1-->3)]-beta-D-glucopyranoside (1), (3beta,22R,25R)-26-(beta-D-glucopyranosyloxy)-22-hydroxyfurost-5-en-3-yl

Structure-activity relationships of retro-dihydrochalcones isolated from Tacca sp.

Numai utilizatorii înregistrați pot traduce articole

Several biologically active compounds have been identified from Tacca species, including glycosides, diarylheptanoids, saponins, withanolides, and the taccalonolide class of microtubule stabilizers. More recently, two cytotoxic retro-dihydrochalcones named evelynin A (7) and taccabulin A (6) were
