Natural Products
Catalog No. Information
CFN99320 Ethylparaben

Ethylparaben is the ethyl ester of p-hydroxybenzoic acid, used as an antifungal preservative and food additive. It is a standardized chemical allergen, has a certain reproductive toxicity to F0 male Drosophila.The physiologic effect of ethylparaben is by means of Increased Histamine Release, and Cell-mediated Immunity.
CFN99715 Forsythoside B

Forsythoside B inhibits inflammatory response, has antioxidant, antisepsis properties, and also has potent neuroprotective effects with a favorable therapeutic time-window, reduce of cerebral ischemia and reperfusion injury degree, attenuating blood-brain barrier (BBB) breakdown. Forsythoside B could inhibit TNF-alpha, IL-6, IκB and modulate NF-κB.
CFN99854 Dihydromorin

trans-Dihydromorin is an effective hypopigmenting agent in normal skin cells, hypopigmenting agents effective in melanoma system may not be effective on normal melanocytes, indicating that a non-tumor melanocyte system is more suitable for the screening of hypopigmenting agents. Dihydromorin shows strong mushroom inhibitory activity with IC50 values lower than 50 microM, more potent than (IC50 = 71.6 microM), it may be as an antibrowning agent in food systems.
CFN99956 Carnosol

Carnosol, a novel agonist of TRPA1 with an EC50 value of 12.46 uM, which exhibits anti-inflammatory, anti-nociceptive, hepatoprotective, antioxidant, anticarcinogen, anti-angiogenic, anti- invasive and antimetastatic properties. Carnosol can cause a significant decrease in both bacterial and yeast growth whilst, it may prove useful as a food antioxidant which could also contribute to the retardation of the microbial spoilage of foods; it also can inhibit adipocyte differentiation in mouse 3T3-L1 cells through induction of phase2 enzymes and activation of glutathione metabolism, it may be a potential drug against obesity-related diseases.
CFN90061 Sorbic acid

Sorbic acid is important food preservatives and powerful fungistatic agents, it inhibits various bacteria, including sporeformers, at various stages of their life cycle (germination, outgrowth and cell division). Sorbic acid is a more potent uncoupler of the membrane potential than acetic acid, the effect may also slow the rate of ATP synthesis significantly and may thus (partially) explain Sorbic acid's effectiveness.
CFN97571 Methyl 4-hydroxybenzoate

Methyl 4-hydroxybenzoate is an anti-fungal agent often used in a variety of cosmetics, personal-care products and food preservatives.
CFN97577 4-Hydroxybenzoic acid

4-Hydroxybenzoic acid, also known as p-hydroxybenzoic acid (PHBA), is a phenolic derivative of benzoic acid and widely used in organic synthesis. 4-Hydroxybenzoic acid derivatives has potential to as pan-HDAC inhibitors with anticancer properties. 4-Hydroxybenzoic acid positively regulates the expression of gum cluster to promote EPS production in PXO99A; it can inhibit most gram-positive and some gram-negative bacteria, with an IC50 of 160 μg/mL.
CFN90281 Cyclo(Pro-Leu)

Cyclo(Pro-Leu) has brine shrimp lethality.
CFN96369 Taxoquinone

Taxoquinone has strong antibacterial effect, it could be used as a promising antibacterial agent in food industry to inhibit the growth of certain important foodborne pathogens. It (100 ug/disc) displays potential anticandidal effect against Candia albicans.Taxoquinone has significant and concentration-dependent antioxidant and free radical scavenging activities, it could as a novel candidate in food and medicine industry as a natural alternative medicine to prevent diabetes mellitus type-2 related disorders and as a depigmentation agent.
CFN96500 (+/-)-Vestitol

Vestitol has antioxidation, anti-inflammatory and antimicrobial activities, it can strongly act in a low dose and concentration and have a promising potential to be applied in the pharmaceutical and food industries. Vestitol inhibits neutrophils migration in the inflammatory process.
