Eupalinolide B is a natural product ,and demonstrates potent cytotoxicity against A-549, BGC-823, SMMC-7721, and HL-60 tumour cell lines.

Afzelin (Kaempferol-3-O-rhamnoside) exhibits several cellular activities such as DNA-protective, antibacterial, antioxidant, anti-inflammatory, and UV-absorbing properties, potentially protecting human skin from UVB-induced damage through a combination of UV-absorbing and cellular actions. Afzelin mitigates mitochondrial damage, promotes mitochondrial biogenesis, and reduces levels of mitophagy-related proteins, parkin and PTEN-induced putative kinase 1.

Tsugaric acid A significantly inhibits superoxide anion formation in fMLP CB-stimulated rat neutrophils and protects human keratinocytes against damage induced by ultraviolet B (UV B) light, indicating that tsugaric acid A can safeguard keratinocytes from photodamage.

Odoriflavene has antioxidant activity, and it also shows inhibition effects on the decrease of glutathione level of rat lens induced by UV irradiation. Odoriflavene shows cytotoxic activity against a SH-SY5Y cell line in vitro.

Desmethylglycitein (6,7,4'-Trihydroxyisoflavone) , is a novel inhibitor of PKCα in suppressing solar UV-induced matrix metalloproteinase 1, which has antioxidant, and anti-cancer activities.

Methyl 3-(2,4-dihydroxyphenyl)propionate is a novel vitamin E derivative that inhibits tyrosinase, which is an antioxidant and inhibits UV-B-induced hyperpigmentation, with potential whitening effects.
