Octisalate (Octyl salicylate) absorbs UVB rays and is used in sunscreens and cosmetics.

Octocrylene (Octocrilene) is used as an ingredient in sunscreens and cosmetics. This organic compound can penetrate into the skin where it acts as a photosensitizer. This results in an increased production of free radicals under illumination.

Sulisobenzone (Sungard) (benzophenone-4), an ingredient in certain sunblocks, protects the skin against damage by short-wave UVA ultraviolet light and UVB.

Dioxybenzone (Benzophenone-8) is an organic agent that blocks UVB and short-wave UVA ultraviolet radiation.

Veratric acid (3,4-Dimethoxybenzoic acid) is a benzoic acid derivative from plants and fruits, possessing antioxidant, anti-inflammatory, and blood pressure-lowering properties.

Vanillin (Zimco) is a single molecule extracted from vanilla beans and also a popular odor used widely in perfume, food and medicine.Vanillin can reversibly and non-competitively inhibit the cellulase activity at appropriate concentrations and the value of IC50 was estimated to be 30 g L.Vanillin protects KSC from UVB irradiation and its effects may occur through the suppression of downstream step of MDM2 in UVB irradiation-induced p53 activation. Vanillin also inhibits yeast growth and fermentation.

Bisoctrizole (Tinosorb M) is a benzotriazole-based organic compound that is added to sunscreens to absorb UV rays.

(±)-CPSI-1306 (2-(3-(2,4-Difluorophenyl)-4,5-dihydroisoxazol-5-yl)-1-morpholinoethan-1-one) is a macrophage migration inhibitory factor (MIF) antagonist and can be used in studies about non-insulin-dependent diabetes mellitus (NIDDM) and the prevention of the deleterious cutaneous effects of acute and chronic UVB exposure.

Sanshool is a natural product isolated from Zanthoxylum bungeanum. Sanshool improves UVB-induced skin photodamage by targeting JAK2/STAT3-dependent autophagy.

Antioxidant agent-20 (Compound 3d) exhibits potent anti-inflammatory and antioxidant activities. It reduces reactive oxygen species (ROS) and apoptosis in a dose-dependent manner. Antioxidant agent-20 demonstrates photoprotective effects on UVB-exposed human skin keratinocytes (HaCaT) (IC50=5.13 µM) by activating Nrf2 HO-1 signaling and inhibiting the NF-κB pathway.

Padimate O, a UVB absorber, is a major ingredient in sunscreens.

Glycerophosphoinositol lysine has an anti-dandruff, anti-inflammatory, anti-aging activity. It significantly suppresses UVB - induced PGE secretion in NHEK keratinocytes.

MHY884 is an inhibitor of tyrosinase that acts by inhibiting UVB-induced activation of the NF-κB signaling pathway through the downregulation of oxidative stress.

Capsorubin is a carotenoid with a variety of biological activities. capsorubin inhibited lipid peroxidation induced by 2,2′-azino(2,4-dimethylvaleronitrile) (AMVN) at a concentration of 167 μM. capsorubin (1 μM) reduced uvb-induced DNA strand breaks and apoptosis in human dermal fibroblasts. formation. It also inhibited the activation of ebvirus early antigen (EBV-EA) induced by 12-carnosine 13-acetate fobo in Raji cells.

1-O-Hexadecyl-sn-glycerol is a bioactive alkyl glyceryl ether. It reduces UVB-induced cell death and production of reactive oxygen species (ROS) and prostaglandin E2 in normal human epidermal keratinocytes (NHEKs). 1-O-Hexadecyl-sn-glycerol (50 μM) increases coronary flow and left ventricular developed pressure and reduces malondialdehyde (MDA) formation ex vivo in a rat heart model of ischemia/reperfusion injury.

Lumisterol (9β,10α-Ergosterol), the (9β,10α)-stereoisomer of Ergosterol, is a steroid compound that acts as a photoprotective agent against UVB-induced DNA damage and demonstrates anti-proliferative activities[1].

12(S)-HHT (12(S)-HHTrE), a fatty acid produced via the arachidonic acid metabolic pathway of cyclooxygenase (COX), is an endogenous ligand and agonist of BLT2, and the 12(S)-HHT/BLT2 axis plays a role in the maintenance of homeostatic aspects of epithelial tissues and in inflammatory responses. 12(S)-HHT inhibits the p38 MAPK/NF-κB pathway through upregulation of MKP-1, leading to reduced IL-6 synthesis in UVB-irradiated HaCaT cells.

(+)-Columbianetin ((S)-Columbianetin) is a new phytoalexin associated with celery (Apium graveolens) resistance to pathogens during storage, it also has antifungal activity. (+)-Columbianetin has anti-inflammatory effects, it promotes histamine release, and inhibits the histamine release by substance P, suggests that it may be helpful in regulating mast cell-mediated allergic inflammatory responses. (+)-Columbianetin can be effectively used to protect keratinocytes from UVB induced damage.

Actinoquinol, a compound effective in absorbing UVB radiation, plays a crucial role in protecting the human eye from photooxidative and other oxidative processes.

Drometrizole Trisiloxane (Mexoryl XL) is a photostable UVA and UVB light filter.

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.
