Isorhapontigenin is an orally active dietary polyphenol. Isorhapontigenin acts as a potent antioxidant that reduces the production of reactive oxygen species (ROS). Isorhapontigenin promotes the binding of JUN to the AP-1 site on the SESN2 promoter, induces SESN2 transcription, triggers MAPK8-dependent JUN activation, and upregulates the expression of PPAR-α, PGC-1α and CPT-1A to facilitate fatty acid oxidation. Isorhapontigenin induces autophagy, apoptosis and preadipocyte differentiation; it inhibits tumor growth, cell invasion, NF-κB transcriptional activity, the PI3K/Akt signaling pathway, STAT1 phosphorylation and MMP-2 expression. Isorhapontigenin alleviates oxidative stress, inflammatory cytokine release and triglyceride accumulation; it increases intracellular ATP levels and promotes Nrf2 nuclear translocation. Isorhapontigenin improves insulin sensitivity in adipose tissue and glucose tolerance, and reduces postprandial blood glucose, insulin and free fatty acid levels. Isorhapontigenin is applicable to research on bladder cancer, liver injury, chronic obstructive pulmonary disease, acute lung injury and type 2 diabetes.

Gnetifolin A is a natural phenolic compound.

Gnetucleistol F is a stilbenolignan isolated from Gnetum cleistostachyum with anti-inflammatory activity. Gnetucleistol F exhibits potent inhibitory activities on TNF-α and malondialdehyde (MDA) with IC₅₀ values of 10.3 and 6.36 μM, respectively. Gnetucleistol F can be used for anti-inflammatory research.
