Octabenzone is a UV absorber/screener. It is used to protect polymers (e.g., polyethylene, polypropylene, polyvinylchloride) against damage by UV light.

Gomisin A (BESIGOMSIN/GA) one of the major dibenzocyclooctadiene lignans isolated from Schisandra chinensis Baill, has proved to possess a variety of pharmacological effects. It has been found to promote hepatocyte growth factor, limit lipid peroxidation, and inhibit apoptosis in acute hepatic injury animal models. Besigomsine also acts as an anti-inflammatory by preventing the release of arachidonic acid in macrophages in vitro. Laboratory evidence suggests that Besigomsine may have anticarcinogenic effects. Chronic administration of Gomisin A had an antihypertensive effect in AngII-induced hypertensive mice. Gomisin A may exert neuroprotective effects by attenuating the microglia-mediated neuroinflammatory response via inhibiting the TLR4-mediated NF-κB and MAPKs signaling pathways. Also it induces marked protective effects against hepatic and renal injury induced by CCl(4) exposure through differential regulation of the MAPK signal transduction pathway.

Lupeol, a biologically active dietary triterpenoid, is found in many medicinal plants and different fruits such as olives, mangos, and strawberries. Lupeol exhibits a wide spectrum of pharmacological properties including anti-inflammatory, anti-cancer, anti-diabetic, anti-microbial, cardioprotective, and hepatoprotective activities. Lupeol inhibits LPS-induced microglial neuroinflammation via the P38-MAPK and JNK pathways and has therapeutic potential to treat various neuroinflammatory disorders. Lupeol possesses antiskin tumor-promoting effects in CD-1 mouse and inhibits conventional as well as novel biomarkers of tumor promotion. It strongly suppressed lipogenesis by modulating the IGF-1R/phosphatidylinositide 3 kinase (PI3K)/Akt/sterol response element-binding protein-1 (SREBP-1) signaling pathway in SEB-1 sebocytes, and reduced inflammation by suppressing the NF-κB pathway in SEB-1 sebocytes and HaCaT keratinocytes. Lupeol exhibited a marginal effect on cell viability and may have modulated dyskeratosis of the epidermis. These results demonstrate the clinical feasibility of applying lupeol for the treatment of acne.

Leupeptin is produced by various species of Actinomycetes. It strongly inhibits proteolysis by plasmin, trypsin and papin. Leupeptin is well absorbed through oral route. Leupeptin has been known to cause various neuropathological changes in vivo resembling those of aging or neurodegenerative processes in the human brain, including the accumulation of neuronal processes and neuronal cytoskeletal abnormalities leading to neurofibrillary tangle (NFT)-like formations. In in vitro experiments, leupeptin protects the heart from myocardial stunning. Leupeptin was found to inhibit tumorigenesis in mouse skin induced by a single, noncarcinogenic dose of 7,12- dimethylbenz(a)anthracene followed by repeated application of croton oil. Tumors that had already been induced were scarcely affected by leupeptin.

SB-202190 is a potent inhibitor of MAPK14 and MAPK11. It has been investigated in a number of preliminary cell-based studies including several cancer models. SB-202190 has been shown to be a UVB protectant; SB-202190 strongly inhibits UVB induced COX-2 protein expression in HaCaT cells and markedly inhibits UVB induced cox-2 mRNA. SB-202190 induces apoptosis through activation of CPP32-like caspases. SB-202190 has been studied in animal models of the Renal Fibrosis and Pemphigus Vulgaris. It should be noted that in vivo use is most effective (at least for renal fibrosis) when SB-202190 is conjugated to lysozyme using a universal linkage system.

4'-demethylepipodophyllotoxin (DMEP) belongs to the class of podophyllotoxin. Podophyllotoxin is a natural product from the roots and rhizomes of Podophyllum species and binds at the colchicine site as a microtubule inhibitor. DMEP is an antimitotic agent which binds to monomeric tubulin, preventing microtubule polymerization. It can reduce the tumor formation and growth in a mouse skin carcinogenesis model. DMEP derivatives exert strong antitumor properties.

JWH-018 is a full agonist synthetic cannabinoid with a high binding affinity to CB1 and CB2 cannabinoid receptors. JWH-018 has not been used in therapy. Many of the risks linked to cannabis use are also present in the case of JWH-018, among them complications in patients suffering from cardiovascular diseases and triggering of acute psychosis. JWH-018 has not been used in therapy. Studies in mice showed anti-inflammatory and cancer chemopreventive properties of JWH-018.

Isopimpinellin is a natural product synthesized by Umbelliferae (or Apiaceae), also known as the carrot or parsley family. It can be found in celery, garden angelica, parsnip, fruits and in the rind and pulp of limes. There have been several studies looking into the effects of Isopimpinellin and other so-called naturally occurring coumarins (such as bergamottin and Imperatorin) as anticarcinogens.

Lawsone (aka hennatannic acid) is a red-orange dye present in the leaves of the henna plant as well as the flower of water hyacinth. Henna extracts have been used by humans as hair and skin dyes for more than 5000 years. Henna extracts have been clinically investigated as a method of reducing dose-limiting Chemotherapy-Induced Palmoplantar Erythrodysesthesia.
