Nicotinamide, a vitamin B3 derivative, is an inhibitor of SIRT1 (IC50=50-180 μM) and SIRT2 (IC50=2 μM). Nicotinamide can be used as a precursor of nicotinamide adenine dinucleotide or NAD+, which can be supplemented by dietary intake and can prevent or treat melanoglossia and pellagra.

1. Ginkgetin has anti-influenza virus and anti-fungal activities. 2. Ginkgetin has anti-inflammatory activity, can down-regulates COX-2 induction in vivo against skin inflammatory responses. 3. Ginkgetin is a good STAT3 inhibitor and may be a useful lead

Terephthalic acid is an isomer and a precursor of the polyester PET. It is used in the production of textiles and plastics, and can also be used to establish skin cancer models.

1.(-)-Fucose (6-Desoxygalactose) can anti-infective, anti-cancer, enhance immunity 2. (-)-Fucose is a skin moisturizing and delaying skin aging 3. (-)-Fucose is a nutritional supplement

Calycosin (Cyclosin) acts as a selective estrogen receptor modulator. Calycosin induces apoptosis in human ovarian cancer SKOV3 cells by activating caspases and Bcl-2 family proteins. Calycosin suppresses breast cancer cell growth via ERβ-dependent regulation of IGF-1R, p38 MAPK and PI3K Akt pathways. Calycosin has antineoplastic effects against osteosarcoma through inducing apoptosis showing in vitro and in vivo investigations. Calycosin was shown to induce angiogenesis in human umbilical vein endothelial cell cultures (HUVEC) in vitro. Calycosin may be an effective skin-lightening agent that regulates the expression of melanogenic enzymes. Calycosin exhibited tyrosinase inhibitory activity with an IC(50) value of 38.4 microM.

Okadaic acid is a potent polyether marine toxin that primarily accumulates in the digestive glands of marine mollusks. It is a highly effective and selective inhibitor of protein phosphatases (PPs). By inhibiting these phosphatases, okadaic acid increases the phosphorylation levels of various proteins, acts as a tumor promoter, and induces tau protein phosphorylation. It can be used to establish models of Alzheimer’s disease and skin cancer.

1. Santalol has good antibacterial, anti-oxidation and anti-tumor activities. 2. α-Santalol is a potent antimitotic agent induced by interference with microtubule assembly. 3. α-Santalol shows a significant antifungal effect against a dermatophytic fungus

Isogarcinol is a natural polyisoprenylated benzophenone first isolated from plant species in the genus Garcinia. It has immunosuppressant actions, inhibiting the protein phosphatase calcineurin (IC50 = 36 μM) and suppressing the proliferation of T cells. Oral administration of isogarcinol in mice decreases delayed type hypersensitivity, prolongs graft survival in allogeneic skin transplants, suppresses inflammation in collagen-induced arthritis, and reduces clinical symptoms in experimental autoimmune encephalomyelitis. Isogarcinol inhibits the proliferation of HL-60 and PC-3 cancer cells (IC50s = 4 and 8 μg ml, respectively) through cell cycle arrest and apoptosis.

Trifolirhizin exerts varying degrees of inhibition on tyrosinase-dependent melanin biosynthesis, and therefore, are candidates as skin-whitening agents.Trifolirhizin possesses potential anti-inflammatory and anti-cancer activities.Trifolirhizin shows in vitro inhibitory effects on the growth of human A2780 ovarian and H23 lung cancer cells. Trifolirhizin inhibits acetylcholine mediated airway smooth muscle (ASM) contraction or directly relaxes pre-contracted ASM independent of β 2 -adrenoceptors.

Brazilein, a natural anti-inflammatory and antioxidant from Caesalpinia sappan L., inhibits adipocyte differentiation by inhibiting PPAR γ induction, inhibits the growth of skin cancer cells through increasing caspase-3 activity, and also possesses insecticidal activity.

Isookanin shows strong diphenyl(2,4,6-trinitrophenyl)iminoazanium (DPPH) radical-scavenging activity with the IC50 value of 7.9 ± 0.53 μM. Isookanin is a potent inhibitor of α-amylase (IC50=0.447 mg ml).

Sanggenol L, a compound from the root bark of Morus alba, inhibits cell growth and promotes apoptotic cell death in melanoma skin cancer cells through activation of the cysteinyl asparaginase cascade and apoptosis-inducing factors. Sanggenol L has anticancer activity and antiproliferative effects and is used in the study of prostate cancer.

6-Prenylapigenin(4',5,7-Trihydroxy-6-prenylflavone) shows potent inhibitory activity on melanin formation, it may be potential sources for skin whitening agents. It also shows moderate cytotoxicities against breast cancer (MDA-MB-435S) and lung adenocarci

Hirsutenone has potent antioxidant activity, it shows significant free radical scavenging activity and exhibits inhibition effect on the mitochondrial lipid peroxidation.Hirsutenone exhibits anti-cancer, and anti-filarial effects, it may exert a preventive effect against microbial endotoxin lipopolysaccharide-induced inflammatory skin diseases through inhibition of ERK pathway-mediated NF-kappaB activation. Hirsutenone attenuates adipogenesis by directly targeting PI3K and ERK during MCE in 3T3-L1 preadipocytes, underscoring the potential therapeutic application of Hirsutenone in preventing obesity.

Karavilagenin D exhibits inhibitory effects on skin-tumor promotion in an in vivo two-stage mouse skin carcinogenesis test based on 7,12-dimethylbenz[a]anthracene (DMBA) as initiator, and with TPA as a promoter. It exhibits inhibition effect against human
