A thorough study on the (E) to (Z) photoisomerization of ferulic acid derivatives (esters, amides of all types, and ketones) was carried out. At the photostationary state, only aliphatic or benzylic tertiary amides reach a nearly complete conversion of (E) isomers into the (Z) ones, whereas for esters, primary and secondary amides or aromatic tertiary amides mixtures of (Z)/(E) ranging from 7 : 93 to 72 : 28 are observed. Ketones show rather limited photoisomerization. However, (Z) ketones may be obtained by the reaction of organometal compounds with an isomerized (Z) Weinreb amide.

A variety of myricetin derivatives bearing ferulic acid amide scaffolds were designed and synthesized. The structures of all title compounds were determined by 1H NMR, 13C NMR, 19F NMR and HRMS. Preliminary bioassays suggested that some of the target compounds exhibited remarkable antiviral activities. In particular, compound 4l possessed significant protective activity against tobacco mosaic virus (TMV), with a half maximal effective concentration (EC50) value of 196.11 μg mL-1, which was better than that of commercial agent ningnanmycin (447.92 μg mL-1). Meanwhile, microscale thermophoresis (MST) indicated that compound 4l has strong binding capability to the tobacco mosaic virus coat protein (TMV-CP) with a dissociation constant (Kd) value of 0.34 μmol L-1, which was better than that of ningnanmycin (0.52 μmol L-1). These results suggested that novel myricetin derivatives bearing ferulic acid amide scaffolds may be considered as an activator for antiviral agents.

Of the three enzymes that regulate the biosynthesis of melanin, tyrosinase and its related proteins TYRP-1 and TYRP-2, tyrosinase is the most important because of its ability to limit the rate of melanin production in melanocytes. For treating skin pigmentation disorders caused by an excess of melanin, the inhibition of tyrosinase enzyme is by far the most established strategy. Cinnamic acid is a safe natural product with an (E)-β-phenyl-α,β-unsaturated carbonyl motif that we have previously shown to play an important role in high tyrosinase inhibition. Since cinnamic acid is relatively hydrophilic, which hinders its absorption on the skin, fifteen less hydrophilic cinnamic amide derivatives (1–15) were designed as safe and more potent tyrosinase inhibitors and were synthesized through a Horner-Wadsworth-Emmons reaction. The use of conc-HCl and acetic acid for debenzylation of the O-benzyl-protected cinnamic amides 40–54 produced the following three results. 1) Cinnamic amides 43, 48, and 53 with a 2,4-dibenzyloxyphenyl group, irrespective of the amine type of the amides, produced complex compounds with high polarity. 2) Cinnamic amides 40–42, 44, 50–52, and 54 with a benzylamino, or diethylamino group produced the desired debenzylated cinnamic amides 1–3, 5, 10–13, and 15. 3) Cinnamic amides 45–47, and 49 with an anilino moiety provided 3,4-dihydroquinolinones 16–19 through intramolecular Michael addition of the anilide group. Notably, the use of BBr3 as an alternative debenzylating agent for debenzylation of cinnamic amides 45–49 with the anilino moiety provided our desired cinnamic amides 6–10 without inducing the intramolecular Michael addition. Debenzylation of cinnamic amides 43, 48, and 53 with a 2,4-dibenzyloxyphenyl group was also successfully accomplished using BBr3 to give 4, 9, and 14. Among the nine compounds that inhibited mushroom tyrosinase more potently at 25 μM than kojic acid, four cinnamic amides 4, 5, 9, and 14 showed 3-fold greater tyrosinase inhibitory activity than kojic acid. The docking simulation using tyrosinase indicated that these four cinnamic amides (?6.2 to ?7.9 kcal/mol) bind to the active site of tyrosinase with stronger binding affinity than kojic acid (?5.7 kcal/mol). All four cinnamic amides inhibited melanogenesis and tyrosinase activity more potently than kojic acid in α-MSH-stimulated B16F10 melanoma cells in a dose-dependent manner without cytotoxicity. The strong correlation between tyrosinase activity and melanin content suggests that the anti-melanogenic effect of cinnamic amides is due to tyrosinase inhibitory activity. Considering that the cinnamic amides 4, 9, and 14, which exhibited strong inhibition on mushroom tyrosinase and potent anti-melanogenic effect in B16F10 cells, commonly have a 2,4-dihydroxyphenyl substituent, the 2,4-dihydroxyphenyl substituent appears to be essential for high anti-melanogenesis. These results support the potential of these four cinnamic amides as novel and potent tyrosinase inhibitors for use as therapeutic agents with safe skin-lightening efficiency.

Abstract: The paper is devoted to the synthesis of arylidene malonic acid monoanilides and cinnamoyl anilines by condensation of malonic acid monoanilides with aromatic aldehydes. The presented synthetic route applies simple, cheap, and commercially available aromatic aldehydes and amines, thus overcoming traditional schemes, which involve derivatives of hydroxycinnamic acids. Besides, a mild and effective pyridine-mediated decarboxylation of carboxylic group at Csp2 in arylidene malonic acid monoanilides leading to cinnamoyl anilines is presented. The structures of obtained selected arylidene derivatives were approved additionally by X-ray analysis. The antiradical properties (2,2-diphenyl-1-picrylhydrazyl and galvinoxyl tests) and structure–activity relationships of the synthesized compounds were studied.

Based on our recent investigations on chalcone derivatives as AChE inhibitors, a series of ferulic acid (FA) tertiary amine derivatives similar to chalcone compounds were designed and synthesized. The results of bioactivity evaluation revealed that most of new synthesized compounds had comparable or more potent AChE inhibitory activity than the control drug Rivastigmine. The alteration of carbon chain linking tertiary amine groups and ferulic acid scaffold markedly influenced the inhibition activity against AChE. Among them the inhibitory activity of compound 6d (IC50: 0.71 ± 0.09 μmol/L) and 6e (IC50: 1.11 ± 0.17 μmol/L) was equal to 15-fold and 9-fold than that of Rivastigmine against AChE (IC50: 10.54 ± 0.86 μmol/L), respectively. Moreover, compound 6d shows the highest selectivity for AChE over butyrylcholinesterase(BuChE) (ratio: 18.3). The kinetic study suggested that compound 6d revealed a mixed-type inhibition against AChE. The result of molecular docking showed that compound 6d combines to AChE with three amino acid sites(Trp84, Tyr334 and Trp279), while combines to BuChE with two amino acid sites (Tyr67 and Gly66) in enzyme domains, respectively. Compound 6d might act as a potential agent for the treatment of Alzheimer's diseases (AD).

Abstract: The design and microwave-assisted synthesis of four series (IIIa–IIIo, Va–Vg, VIIa–VIIg and IXa–IXe) of mono and bis-amide derivatives of ferulic acid have been achieved under solvent-free conditions and, subsequently characterized by spectroscopic techniques. During thermal analysis, all the compounds were found stable up to 100?°C and decomposed through single step at higher temperature. The derivatives were screened for their in vitro cytotoxicity and antioxidant activity, respectively and observed that compound Vb was most active against breast (MCF-7; IC50?=?07.49?μM and MDA-MB-231; IC50?=?07.28?μM), Vd against lung (A549; IC50?=?07.11?μM) and liver (HepG2; IC50?=?08.32?μM), and Ve against cervical (HeLa; IC50?=?07.14?μM) cancer cell lines, while compounds IIIf, IIIl, IIIo, VIIe and IXa–IXe were found to exhibit the strong antioxidant activity with respect to their parent molecule. Previous reports for the biological applications of ferulic acid amides also confirmed the importance of work presented here. The 3D-QSAR studies for anticancer and antioxidant activities were also performed by using CoMFA, and the corresponding contour maps of electrostatic and steric fields have been computed. Statistical analysis between experimental and CoMFA-predicted data for pIC50 have been accomplished by curve fitting analysis which showed the significant correlation.

In order to discover new compounds with antiplatelet aggregation activities, some ferulic acid (FA) derivatives were designed and synthesized. The in vitro antiplatelet aggregation activities of these compounds were assessed by turbidimetric test. The results showed that the target compound 7f had potent antiplatelet aggregation activity with its IC50 27.6 μmol/L, and 7f can be regarded as a novel potent antiplatelet aggregation candidate.

A series of ferulic acid amides with extended P1' groups were synthesized and tested for their inhibitory activities on matrix metalloproteinase (MMP)-1, MMP-2, and MMP-9. Preliminary structure-activity relationship analysis and docking studies indicated that ferulic acid amides with electron-donating groups at the amino phenyl ring showed better inhibitory activities and selectivity than those with electron-withdrawing groups. Compound 3e, which had a hydroxyl group at meta-position of amino phenyl ring, showed considerable inhibitory activities against MMP-2, MMP-9 and best selectivity over MMP-1. The findings of this study would provide information for the exploitation and utilization of ferulic acid as MMP inhibitor for metastatic tumor treatment.

Parahydroxycinnamoyl amides are easily prepared from the lithioamines and the iminium salts of alkylated acids.Depending on the amine nucleophilic character, the yields are satisfactory with the aminopyridine derivatives, good for a natural product as the N-feruloyltryptamine 10.A good inactivation effect of the target enzyme CADH is observed with the aminopyridine derivatives, in particular with the N-feruloyl 2-amino pyridine 11.
