1,3-Dihydroxyacetone is the main active ingredient in sunscreen tanning skin care preparations, an important precursor for the synthesis of a variety of fine chemicals, and a food additive that can be produced on an industrial scale by microbial fermentation on Gluconobacter oxydans. 1,3-Dihydroxyacetone has the ability to increase cAMP levels. 1,3-Dihydroxyacetone has the ability to increase cAMP levels.

Trans-caffeic acid stearyl ester is posited to inhibit melanogenesis signaling while suppressing cAMP levels and, subsequently, MC1R, MITF, tyrosinase, TRP-2 and TRP-1 down-regulation, resulting in the suppression of tyrosinase activity, DOPA oxidase activity and melanin synthesis.

Luteolin 7-sulfate, derived from the marine plant Phyllospadix iwatensis Makino, suppresses TYR gene expression by intervening in a signaling pathway involving the cAMP-responsive element binding protein (CREB) and microphthalmia-associated transcription factor (MITF). This inhibition ultimately leads to a decrease in melanin synthesis.

3,5,6,7,8,3',4'-Heptemthoxyflavone exhibits neuroprotective, chemopreventive, anti-allergic, anti-inflammatory, immunomodulatory, anti-aging, and photoprotective effects; it inhibits collagenase activity, induces type I procollagen synthesis in HDFn cells, and combats nitric oxide (NO) carcinogenesis.

Paraxanthine (1,7-dimethylxanthine) is a metabolite of caffeine (sc-202514) which functions as an adenosine receptor ligand and a PARP-1 inhibitor in pulmonary epithelial cells. Studies suggest that Paraxanthine is structurally similar to caffeine and possibly mediates the physiological effects of caffeine. Also Paraxanthine acts as a competitive phosphodiesterase inhibitor, which increases intracellular cAMP, activates PKA, inhibits TNF-α and leukotriene synthesis. In addition, Paraxanthine acts as a Na+ K+ ATPase enzymatic effector.
