Tenacissoside H is a Chinese medicine monomer extracted, isolated from Caulis Marsdeniae Tenacissimae. IC50 value: Target: In vitro: TDH significantly inhibited cells proliferation in a time-and-dose-dependent manner. TDH arrested the cell cycle in S phase and significantly inhibited PI3K and NF-κB mRNA expression, compared with blank controlled group (P < 0.05). [1] In vivo: TDH strongly inhibits tumor growth and volume. PCNA expression was significantly decreased after treatment of TDH. TDH downregulated proteins expression in PI3K/Akt-NF-κB transduction cascade (P < 0.05). [1]
