Cudraflavone B has anti-proliferative activity, mouse brain monoamine oxidase (MAO) inhibitory effects, apoptotic actions in human gastric carcinoma cells and mouse melanoma cells, and hepatoprotective activity. It may be a lead for the development of a potential candidate for human oral squamous cell carcinoma cells.
Dehydroglyasperin C is a potent NAD(P)H:oxidoquinone reductase (NQO1) and phase 2 enzyme inducer. Dehydroglyasperin C possesses potent antioxidant, cancer chemopreventive, and neuroprotective activities, it has protective effects against chronic diseases
Latifolin is a strong DPPH-scavenger, it attenuates inflammatory responses by inhibiting NF-κB activation via Nrf2-mediated heme oxygenase-1 expression. Latifolin displays potent anticarcinogenic phase II marker enzyme, quinone reductase (QR) inducing activity and high chemopreventive indices. Latifolin also shows antifungal activity against white- and brown-rot fungi.
Physalin H is an Hh signaling inhibitor blocks GLI1-DNA-complex formation, it also strong quinone reductase induction activity with IR (Induction ratio, QR induction activity) value of 3.74±0.02. Physalin H shows immunosuppressive effects on T cells both
Ganoderiol F has anti-inflammatory, cytotoxic and anti-HIV activity, it inhibits activity of topoisomerases in vitro, and it inhibits human immunodeficiency virus-1 protease with IC(50) values of 20-40 microM. It induced HO-1 expression, activation of the mitogen-activated protein kinase EKR and up-regulation of cyclin-dependent kinase inhibitor p16 and suppressed lipopolysaccharide (LPS)-induced nitric oxide (NO) production.
4-O-Methylbutein (2',3,4'-trihydroxy-4-methoxychalcone) may have anti-inflammation activity, it is a potent heme oxygenase-1 (HO-1) inducer, the upregulation of HO-1 has proven to be a useful tool for fighting inflammation.
Flavoglaucin exhibits significant inhibitory effects on PTP1B, the IC50 value of 13.4, micrometer; it also shows good binding affinity for human opioid or cannabinoid receptors. Flavoglaucin appears to be an antitumor promoter, it also has anti-inflammato
Hirsutenone has potent antioxidant activity, it shows significant free radical scavenging activity and exhibits inhibition effect on the mitochondrial lipid peroxidation.Hirsutenone exhibits anti-cancer, and anti-filarial effects, it may exert a preventive effect against microbial endotoxin lipopolysaccharide-induced inflammatory skin diseases through inhibition of ERK pathway-mediated NF-kappaB activation. Hirsutenone attenuates adipogenesis by directly targeting PI3K and ERK during MCE in 3T3-L1 preadipocytes, underscoring the potential therapeutic application of Hirsutenone in preventing obesity.
Nrf2 HO-1 activator 2 (compound 13m), a difluoro-substituted derivative, is a highly potent activator of Nrf2 HO-1. It exhibits substantial neuroprotective and antioxidant properties by activating the Nrf2 HO-1 pathway through phosphorylation of ERK1 2, JNK, or Akt in PC12 cells. This compound finds utility in the investigation of Parkinson's disease (PD) [1].
