Taccaceae

Taccalonolide A is a microtubule stabilizer, which is a steroid isolated from Tacca chantrieri, with cytotoxic and antimalarial activities. Taccalonolide A causes G₂-M accumulation, Bcl-2 phosphorylation and initiation of apoptosis. Taccalonolide A is effective in vitro against cell lines that overexpress P-glycoprotein (Pgp) and multidrug resistance protein 7 (MRP7), with an IC₅₀ of 622 nM for SK-OV-3 cells.

Taccalonolide B is microtubule stabilizer isolated from Tacca plantaginea, with antitumor activity. Taccalonolide B is effective in vitro against cell lines that overexpress P-glycoprotein (Pgp) and multidrug-resistance protein (MRP7). Taccalonolide B inhibits growth of SK-OV-3 cells with an IC₅₀ of 208 nM.

(3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside is a diarylheptanol glycoside compound isolated from Tacca plantaginea. (3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside significantly inhibit TNF-α-induced NF-κB transcriptional activity (IC₅₀ = 9.4 μM). (3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside significantly activates PPAR transcriptional activity (EC₅₀ = 9.9 μM) and has a specific activating effect on PPAR β(δ) (EC₅₀ = 23.1 μM). (3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside is non-toxic to cells at the tested concentration. (3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside can be used for research on inflammatory conditions.

Chantriolide A is a withanolide glucoside that can be isolated from the whole plant of Tacca plantaginea.

Chantriolide B is a new withanolide glucoside. Chantriolide B can be isolated from the rhizomes of Tacca chantrieri. Chantriolide B does not inhibit NO in cells.

α-Synuclein inhibitor 14 (Compound 3) is a diarylheptanoid that can be isolated from Alpinia officinarum. α-Synuclein inhibitor 14 can inhibit the aggregation of α-synuclein, with an inhibition rate of 72.4% at a concentration of 10 μM. α-Synuclein inhibitor 14 can be used in the research of neurodegenerative diseases such as Parkinson's disease.

(3R,5R)-Octahydrocurcumin (Compound 7) is gut microbial metabolite of Curcumin (HY-N0005). (3R,5R)-Octahydrocurcumin exhibits neuroprotective efficacy against Aβ25-35-induced cell damage in SH-SY5Y, and anti-inflammatory activity against LPS-stimulated mouse microglial BV-2.
