Design, synthesis of N-phenethyl cinnamide derivatives and their biological activities for the treatment of Alzheimer's disease: Antioxidant, beta-amyloid disaggregating and rescue effects on memory loss

Gx-50 is a bioactive compound for the treatment of Alzheimer's disease (AD) found in Sichuan pepper (Zanthoxylum bungeanum). In order to find a stronger anti-AD lead compound, 20 gx-50 (1-20) analogs have been designed and synthesized, and their molecular structures were determined based on nuclear magnetic resonance (NMR) and mass spectrometry (MS) analysis, as well as comparison with literature data. Compounds 1-20 were evaluated for their anti-AD potential by using DPPH radical scavenging assay for considering their anti-oxidant activity, thioflavin T (ThT) fluorescence assay for considering the inhibitory or disaggregate potency of Ab, and transgenic Drosophila model assay for evaluating their rescue effect on memory loss. Finally, compound 13 was determined as a promising anti-AD candidate.

Mining Plants for Bacterial Quorum Sensing Modulators

The bacterial plant pathogen Agrobacterium tumefaciens uses quorum sensing (QS) in order to regulate the transfer of DNA into the host plant genome, and this results in the induction of crown gall tumors. The deleterious results of these infections are wi

METHOD OF TREATING OR PREVENTING HYPERLIPIDEMIA WITH CAFFEAMIDE DERIVATIVES

The present invention provides a method of treating or preventing hyperlipidemia in a subject in need thereof. Such method includes, specifically, administrating to the subject a therapeutically effective amount of a caffeamide derivative. The present invention also provides a pharmaceutical composition containing, primarily, the caffeamide derivative. The method and pharmaceutical composition of the present invention can effectively and significantly lower the high-fat diet-induced body weight gain and absolute visceral fat weight as well as the concentration of triglycerides and free fatty acids in blood, and levels of total lipid and triacylglycerol in liver tissue. In addition, the caffeamide of the present invention also reduces size of adipocyte, hepatocellular ballooning phenomenon, and liver steatosis. Through promotion of phosphorylation of 5′ adenosine monophosphate-activated protein kinase (AMPK) in muscle and liver, the caffeamide derivatives of the present invention is suitable for ameliorating or remedying hyperlipidemia.

Protective effect of caffeic acid derivatives on tert-butyl hydroperoxide-induced oxidative hepato-toxicity and mitochondrial dysfunction in HepG2 cells

Oxidative stress results in structural and functional abnormalities in the liver and is thought to be a crucial factor in liver diseases. The aim of this study was to investigate the cytoprotective and antioxidant effects of caffeic acid (CA) derivatives

Synthesis of caffeic acid phenethyl ester derivatives, and their cytoprotective and neuritogenic activities in PC12 cells

Twenty-one caffeic acid phenethyl ester (CAPE) derivatives were synthesized, and characterized by IR, HR-MS, 1H and 13C NMR analyses. All compounds were evaluated for their cytoprotective effects against H2O2-induced cytotoxicity and neuritogenic activities in the neurite outgrowth in PC12 cells. Compounds 1 and 20 exhibited stronger cytoprotective activities than their parent compound CAPE at 4 nM. Compounds 1, 4, 12 and 13 showed potential neuritogenic activities at 0.5 nM, while compounds 19 and 20 induced neurite outgrowth at 10 nM. The results from this study suggested that CAPE and its derivatives may be potential functional food ingredients for the prevention of neurodegenerative diseases.

Antiproliferative, antiandrogenic and cytotoxic effects of novel caffeic acid derivatives in LNCaP human androgen-dependent prostate cancer cells

Caffeic acid and its naturally occurring derivative caffeic acid phenethyl ester (CAPE) have antiproliferative and cytotoxic properties in a variety of cancer cell lines without displaying significant toxicity toward healthy cells, and are considered to be potential anticancer agents. However, little is known about their effects on prostate cancer cells. We synthesized and evaluated the effects of caffeic acid, CAPE (2) and 18 synthetic derivatives on cell viability and androgen-dependent cell proliferation, subcellular localisation and expression of androgen receptor (AR) and secretion of prostate-specific antigen (PSA) in LNCaP human hormone-dependent prostate cancer cells. Several synthetic derivatives of CAPE were strong, concentration-dependent cytotoxic agents in LNCaP cells with IC50 values in the 6.8-26.6 μM range, potencies that were up to five-fold greater than that of CAPE (33.7 ± 4.0 μM). A number of caffeic acid derivatives were inhibitors of androgen-stimulated LNCaP cell proliferation with concomitant inhibition of DHT-stimulated PSA secretion. Compound 24 was the most cytotoxic and antiproliferative caffeic acid derivative (IC50 values of 6.8 ± 0.3 and 2.4 ± 0.8 μM, respectively) inhibiting DHT-stimulated cell proliferation and PSA secretion statistically significantly at concentrations as low as 0.3 μM. Exposure to DHT increased cytoplasmic and nuclear AR levels and co-treatment with increasing concentrations of compound 24 or CAPE (2), notably, further increased these levels. In conclusion, a number of synthetic derivatives of caffeic acid are potent inhibitors of androgen-dependent prostate cancer cell proliferation and viability, acting, at least in part, via an antiandrogenic mechanism that involves increased nuclear accumulation of (presumably inactive) AR.

Synthesis and structure-activity relationship analysis of caffeic acid amides as selective matrix metalloproteinase inhibitors

Four series of acid amides were synthesized, and through measurement using a fluorogenic substrate assay with human recombinant MMP-1, MMP-2 and MMP-9, compound 3f showed considerable inhibitory activities against MMP-2, MMP-9 and the best selectivity over MMP-1. Preliminary structure-activity relationship analysis indicated that caffeic acid amides with electron-donating groups at para-position of amino phenyl group showed better inhibitory activities and selectivity than those with electron-withdrawing groups, and the presence of adjacent dihydroxy in the caffeoyl group was very important for the MMP-2 and MMP-9 inhibitory activities.

Electrochemical oxidation of caffeic and ferulic acid derivatives in aprotic medium

We studied the electrochemical behaviour as a function of the structure of a series of caffeic and ferulic acids derivatives as well as their corresponding redox moieties catechol and guaiacol by cyclic voltammetry. Results revealed that the medium is key

Synthesis and antioxidant capacities of hydroxyl derivatives of cinnamoylphenethylamine in protecting DNA and scavenging radicals

Cinnamoylphenethylamine (CNPA) derivatives including feruloylphenethylamine (FRPA), caffeoylphenethylamine (CFPA), cinnamoyltyramine (CNTA), feruloyltyramine (FRTA) and caffeoyltyramine (CFTA) were synthesized in order to investigate the influence of the number and position of hydroxyl group on Cu2+/glutathione (GSH) and 2,2′-azobis(2-amidinopropane hydrochloride) (AAPH)-induced oxidation of DNA. The radical-scavenging properties of these CNPA derivatives were also evaluated by trapping 2,2′-azinobis(3-ethylbenzothiazoline-6-sulphonate) cationic radical (ABTS), 2,2′-diphenyl-1-picrylhydrazyl radical (DPPH) and galvinoxyl radical. In addition, these CNPA derivatives were tested by linoleic acid (LH)-β-carotene-bleaching experiment. The chemical kinetic was employed to treat the results from AAPH-induced oxidation of DNA and gave the order of antioxidant ability as CFTA > CFPA > FRTA > FRPA. CFTA and CFPA also possessed high abilities to inhibit Cu2+/GSH-mediated degradation of DNA, whereas FRPA and FRTA can protect LH against the auto-oxidation efficiently. Finally, CFPA and FRPA exhibited high activity in trapping ABTS, DPPH and galvinoxyl radicals. Therefore, the cinnamoyl group bearing ortho-dihydroxyl or hydroxyl with ortho-methoxyl benefited for CNPA derivatives to protect DNA, while hydroxyl in tyramine cannot enhance the radical-scavenging abilities of CNPA derivatives.
