Description:
Pseudoprotodioscin exhibits anti-inflammatory and anticancer activities, it shows a weaker suppressing effect on the production of inflammatory cytokines, and can suppress melanogenesis in B16F1 cells.

Anti-inflammatory and anti-melanogenic steroidal saponin glycosides from Fenugreek (Trigonella foenum-graecum L.) seeds.
Fenugreek seed ( Trigonella foenum-graecum L.) is used as an herbal medicine for treating metabolic and nutritive dysfunctions.
METHODS AND RESULTS:
To determine if this plant has other beneficial effects, we tested the inhibitory activities of a methanol (MeOH) extract of fenugreek seed on the production of inflammatory cytokines and melanin synthesis in cultured cell lines in vitro. The MeOH extract inhibited the production of phorbol-12-myristate-13-acetate-induced inflammatory cytokines such as tumor necrosis factor (TNF)-α in cultured THP-1 cells, and also restrained the intracellular synthesis of melanin in murine melanoma B16F1 cells. We isolated three active constituents from fenugreek seed extracts. These were identified as the steroidal saponins 26- O-β-D-glucopyranosyl-(25 R)-furost-5(6)-en-3 β,22 β,26-triol-3- O-α-L-rhamno-pyranosyl-(1'' → 2')-O-[β-D-glucopyranosyl-(1''' → 6')- O]-β-D-glucopyranoside 1, minutoside B 2, and Pseudoprotodioscin 3. Compounds 1 and 2 strongly suppressed the production of inflammatory cytokines, whereas 3 showed a weaker suppressing effect. Melanogenesis in B16F1 cells was significantly suppressed by 1 and 3, and weakly suppressed by 2. All three compounds showed moderate cytotoxicities.
CONCLUSIONS:
These results indicate that fenugreek extract and its active constituents could protect against skin damage.

Two new steroidal saponins from the rhizomes of Dioscorea panthaica and their cytotoxic activity.
Two new steroidal saponins, dioscoresides C (1) and D (2), along with a new natural product, pregnadienolone 3-O-beta-gracillimatriose (3), and two known compounds, pregnadienolone 3-O-beta-chacotrioside (4) and Pseudoprotodioscin (5), were isolated from the rhizomes of Dioscorea panthaica Prain et Burkill.
METHODS AND RESULTS:
On the basis of extensive NMR studies and chemical evidence, dioscoresides C and D were determined to be 26-O-beta-D-glucopyranosyl-3 beta,26-dihydroxy-23(S)-methoxy-25(R)-furosta-5,20(22)-dien-3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucopyranoside and 26-O-beta-D-glucopyranosyl-3 beta,26-dihydroxy-20,22-seco-25(R)-furosta-5-en-20,22-dine-3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1--> 4)]-beta-D-glucopyranoside.
CONCLUSIONS:
These compounds showed mild cytotoxicity against the cancer cell lines, A375, L929, and HeLa, in a dose-dependent manner.
