| Solvent: | Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc. |
| Storage: | Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C). Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour. Need more advice on solubility, usage and handling?

| After receiving: | The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling. |

| Mitogen-activated protein kinase (MAPK) signalling pathway can regulate inflammatory and immune responses. N-trans-Feruloyltyramine (FLA) is an active phenylpropanoid compound. It possesses antioxidant, antimicrobial, anti-melanogenesis, and anticancer activities. However, the precise molecular mechanisms underlying N-trans-Feruloyltyramine modulation of cytokine expression in LPS-stimulated RAW 264.7 macrophages have not been fully investigated. In this study, we examined the mechanisms underlying the immunomodulative effects of N-trans-Feruloyltyramine isolated from Arcangelisia gusanlung. N-trans-Feruloyltyramine strongly suppressed mRNA expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), but not tumor necrosis factor (TNF)-α, thereby inhibiting the production of nitric oxide (NO) and prostaglandin E2 (PGE2) in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Furthermore, N-trans-Feruloyltyramine also inhibited nuclear translocation of activation protein (AP)-1, and simultaneously decreased the expression and phosphorylation of the c-Jun N-terminal kinase (JNK) protein. These results suggest that the anti-inflammatory effects of FLA might be attributed to downregulation of COX-2 and iNOS via suppression of AP-1 and the JNK signalling pathway in RAW 264.7 macrophages. | |

| Enhanced oxidative stress and inflammation play important roles in the pathogenesis of Alzheimer's disease (AD). Amyloid β-peptide (Aβ), a major component of amyloid plaques, is considered to have a causal role in the development and progress of AD by being the initiator of a pathological cascade leading to oxidative stress. The present study investigated the effect of N-trans-Feruloyltyramine (NTF) purified from Polyalthia suberosa, an alkaloid shown to protect against oxidative stress and cell death. Pre-treatment of rat primary cortical cell cultures with 25-250μM N-trans-Feruloyltyramine significantly attenuated 10μM Aβ(1-42)-induced neuronal death in a dose-dependent manner. Apoptotic cell death was demonstrated morphologically as well as by detection of the presence of activated caspase-3 and Bax, levels of which could be reduced by N-trans-Feruloyltyramine pre-treatment. N-trans-Feruloyltyramine also reduced production of reactive oxygen species induced by Aβ(1-42). These findings suggest that the protective effect of N-trans-Feruloyltyramine against Aβ(1-42)-induced neuronal death might be due to its antioxidative property. | |

| In this study, we examined the effect of N-trans-Feruloyltyramine (FA) on melanogenesis in mouse B16 melanoma cells. Melanogenesis was inhibited by N-trans-Feruloyltyramine in a dose-dependent manner. N-trans-Feruloyltyramine exhibited a greater potency than kojic acid as a standard inhibitor of melanogenesis. Moreover, treatment of B16 melanoma cells with N-trans-Feruloyltyramine was found to cause marked decreases in the expression levels of tyrosinase. N-trans-Feruloyltyramine-induced downregulation of tyrosinase resulted in suppression of melanin biosynthesis in murine B16 melanoma cells. | |

| Polygonum sachalinensis is a widespread invasive plant in Europe. Chemical profiles of its different organs were studied by HPLC-UV-ESI/MS. Seven major constituents quercetin-3-O-beta-D-galactopyranoside, quercetin-3-O-arabinopyranoside, lapathoside D, N-trans-Feruloyltyramine, lapathoside C, hydropiperoside, and vanicoside B were isolated and identified. The free radical-scavenging, alpha/beta-glucosidase, and acetylcholinesterase inhibitory activities of crude MeOH extracts and isolated compounds were studied. The structure-activity relationships were discussed. The chemical profiles revealed flavonoids and phenylpropanoids are the major compounds of all the organs of this plant. Quercetin-3-O-arabinopyranoside, lapathoside D, N-trans-Feruloyltyramine, lapathoside C and hydropiperoside were isolated from this species for the first time. In the alpha-glucosidase bioassay, quercetin-3-O-beta-D-galactopyranoside, lapathoside D and N-trans-Feruloyltyramine demonstrated stronger activities than the positive reference acarbose. The trend in scavenging power showed no relation to enzyme inhibition in the test models. |
