ferric reducing

Lirinidine is an alkaloid isolated from L. tulipifera leaves with antioxidant and anticancer properties. It exhibits moderate iron-reducing capacity and small free radical scavenging capacity in vitro and can be used in cosmetic research.

Isoangustone A has antitumor activity, it can induce G1 cycle arrest in DU145 human prostate and 4T1 murine mammary cancer cells, it inhibits cell proliferation by targeting PI3K, MKK4, and MKK7 in human melanoma. Isoangustone A dampens mesangial sclerosis associated with inflammation in response to high glucose through hindering TGF-β and NF-κB signaling. Isoangustone A also shows strong ferric reducing activities and effectively scavenged DPPH, ABTS(+), and singlet oxygen radicals.

Dehydroglyasperin D exhibits anticancer, anti-inflammatory, anti-obesity, antioxidant and anti-aldose reductase effects, it inhibits the proliferation of HT-29 human colorectal cancer cells through direct interaction with phosphatidylinositol 3-kinase; it also mediates suppression of both COX-2 expression and the MLK3 signalling pathway through direct binding and inhibition of MLK3. Dehydroglyasperin D shows strong ferric reducing activities and effectively scavenged DPPH, ABTS(+), and singlet oxygen radicals.
