Oh JH, Karadeniz F, Lee JI, Seo Y, Kong CS. Oleracone C from Portulaca oleracea attenuates UVB-induced changes in matrix metalloproteinase and type I procollagen production via MAPK and TGF-β/Smad pathways in human keratinocytes. Int J Cosmet Sci 2022; 45:166-176. [PMID: 36415152 DOI: 10.1111/ics.12828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 10/17/2022] [Accepted: 11/21/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Chronic exposure to ultraviolet (UV) radiation induces photo-oxidation, which in turn causes the overproduction of matrix metalloproteinases (MMPs) and collagen degradation. These symptoms are referred to as photoaging, which is characterized by skin thickness, irregular pigmentation, elastosis and coarse wrinkles. In this study, the protective effects of oleracone C isolated from Portulaca olerace against UVB-induced changes in MMPs and type I procollagen production were investigated in human keratinocytes. METHODS Human immortalized keratinocytes have been used as an in vitro cell model to study the abnormal skin barrier development such as in photoaging. The effects of the compound on cell viability were determined by colorimetric MTT assay. This study also measured ROS production using DCFH-DA assay. Releases of MMPs and type Iα1 procollagen were analysed by ELISA. RT-PCR and Western blot were carried out to test the expressions of mRNA and proteins related to MMPs and type I procollagen biosynthesis. RESULT Effect of oleracone C against UVB-mediated oxidative stress was evaluated measuring its ability to eliminate UVB-induced activation of reactive oxygen species (ROS). Treatment of oleracone C hindered the production of intracellular ROS. UVB exposure increased MMPs (MMP-1, MMP-2 and MMP-9) release from keratinocytes and decreased the release of type I procollagen. Treatment with oleracone C reversed these effects of UVB exposure. Oleracone C treatment also diminished the intracellular expression of MMP-1, MMP-2 and MMP-9 and elevated the type I procollagen. Oleracone C suppressed the UVB irradiation-dependent upregulation phosphorylation of p38 and ERK1/2 in the mitogen-activated protein kinase (MAPK) pathway. Furthermore, oleracone C stimulated collagen production through the TGF-β signalling pathway, which activates collagen synthesis in UVB-irradiated keratinocytes. CONCLUSION These findings reasonably suggest ameliorating the potential of oleracone C against the UVB-induced photoaging of the human keratinocytes.

Abstract
The biological effects attributed to nitric oxide (• NO) and nitroxyl (HNO) have been extensively studied, propelling their array of putative clinical applications beyond cardiovascular disorders toward other age-related diseases, like cancer and neurodegenerative diseases. In this context, the unique properties and reactivity of the N-O bond enabled the development of several classes of compounds with potential clinical interest, among which • NO and HNO donors, nitrones, and nitroxides are of particular importance. Although primarily studied for their application as cardioprotective agents and/or molecular probes for radical detection, continuous efforts have unveiled a wide range of pharmacological activities and, ultimately, therapeutic applications. These efforts are of particular significance for diseases in which oxidative stress plays a key pathogenic role, as shown by a growing volume of in vitro and in vivo preclinical data. Although in its early stages, these efforts may provide valuable guidelines for the development of new and effective N-O-based drugs for age-related disorders. In this report, we review recent advances in the chemistry of NO and HNO donors, nitrones, and nitroxides and discuss its pharmacological significance and potential therapeutic application.

Abstract
A series of homoisoflavonoid derivatives was designed, synthesized and evaluated as potential multi-functional anti-Alzheimer's agents for their inhibitory activity on cholinesterase and monoamine oxidase. Among them, compound 16 showed moderate acetylcholinesterase (AChE) inhibitory activity (eeAChE IC50 = 0.89 ± 0.02 μM; hAChE IC50 = 0.657 ± 0.002 μM) and significant monoamine oxidase B (MAO-B) inhibitory activity (hMAO-B IC50 = 0.0372 ± 0.0002 μM). Kinetic analysis of AChE, MAO-B inhibition and molecular modeling studies revealed that compound 16 is a dual binding site inhibitor of AChE and noncompetitive inhibitor of MAO-B. Furthermore, 16 could penetrate through the blood-brain barrier (BBB) in vitro. Most importantly, oral administration of 16 demonstrated no marked signs of acute toxicity and it could significantly reverse scopolamine-induced memory impairment in mice. These results suggested that compound 16 is a promising multifunctional drug candidate with potential effect for the treatment of Alzheimer's disease.

Abstract
A series of 3-benzylidene-4-chromanone derivatives (3-20) were synthesized and the structure-activity relationships for antioxidant and α-glucosidase inhibitory activities were evaluated. Among synthesized compounds, compounds 5, 13, 18, which contain catechol moiety, showed the potent 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity (5: EC50 13 µM; 13: EC50 14 µM; 18: EC50 13 µM). The compounds 12, 14, 18 showed higher α-glucosidase inhibitory activity (12: IC50 15 µM; 14: IC50 25 µM; 18: IC50 28 µM). The compound 18 showed both of potent DPPH radical scavenging and α-glucosidase inhibitory activities. These data suggest that 3-benzylidene-4-chromanone derivatives, such as compound 18, may serve as the lead compound for the development of novel α-glucosidase inhibitors with antioxidant activity.

Abstract
In this study, a series of coumarin-3-acylamino derivatives containing phenethylamine moiety or tyramine moiety were synthesized and their antioxidant activities were evaluated by Cu(2+)/glutathione(GSH)-, ˙OH- and 2,2'-azobis(2-amidinopropane hydrochloride)(AAPH)-induced oxidation of DNA. It was found that both hydroxyl and ortho-methoxy groups at A ring, hydroxyl group at B ring and peptide bond can enhance the abilities of coumarin-3-acylamino derivatives to protect DNA against ˙OH- and AAPH-induced oxidation. Moreover, these coumarin-3-acylamino derivatives were employed to scavenge 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical (ABTS(+˙)). We found that tyramine moiety, hydroxyl and ortho-methoxy are the key groups to enhance the activities of antioxidants to quench ABTS(+˙). Therefore, tyramine linked with coumarin-3-carboxyl acid which containing hydroxyl and ortho-methoxy exhibited powerful antioxidant abilities.

Abstract
4-Thiaflavan is a sulfur-substituted flavonoid with a benzoxathiin scaffold. The aim of this work is to compare abilities of sulfur and oxygen atom, hydroxyl groups, and ferrocene moiety at different positions of 4-thiaflavan to trap radicals and to inhibit DNA oxidation. It is found that abilities of thiaflavans to trap radicals and to inhibit DNA oxidation are increased in the presence of ferrocene moiety and are further improved by the electron-donating group attaching to thiaflavan skeleton. It can be concluded that the ferrocene moiety plays the major role for thiaflavans to be antioxidants even in the absence of phenolic hydroxyl groups. On the other hand, the antioxidant effectiveness of phenolic hydroxyl groups in thiaflavans can be improved by the electron-donating group. The influences of sulfur and oxygen atoms in thiaflavans on the antioxidant property of para-hydroxyl group exhibit different manners when the thiaflavans are used to trap radicals and to inhibit DNA oxidation.

Abstract
The hydroxyl-substituted benzoic acid (as phenyl group A in the product), aniline (as phenyl group B in the product), benzaldehyde (as phenyl group C in the product), and four isocyanides are employed to synthesize bis-amide via an Ugi four-component reaction. The effects of the obtained 20 bis-amides on quenching radicals and inhibiting DNA oxidation are estimated. It is found that the antioxidant effectiveness of bis-amide generated by hydroxyl groups is markedly influenced by the structural feature derived from isocyanide. The phenolic hydroxyl group attaching to phenyl group A plays a major role in scavenging radicals, and the radical-scavenging property is reinforced by the structural moiety introduced from ferrocenylmethyl isocyanide. The same conclusion is also obtained when bis-amides are used to inhibit DNA oxidation. It is still found that the ferrocenylmethyl moiety enhances the antioxidant effect of hydroxyl group at phenyl group A in protecting DNA against the oxidation. Moreover, when the bis-amide is prepared by the same isocyanide, e.g. ethyl isocyanoacetate, it is found that the hydroxyl group at phenyl group C plays the major role in inhibiting DNA oxidation, followed by the hydroxyl groups attaching to phenyl groups B and A.

Abstract
A novel series of natural product like dibenzofuran embodied homoisoflavonoids [(E)-3-(dibenzo[b,d]furan-2-ylmethylene)chroman-4-ones] designed by molecular hybridization were synthesized in very good yields via a sequence of reactions involving base catalyzed Baylis-Hillmann (BH) reaction of 2-dibenzofuran carboxaldehyde and methyl acrylate; bromination of BH adduct; condensation of resulted allylic bromide with substituted phenols or 2-dibenzofuranol followed by cyclization. Among the all 11 new compounds screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv (MTB), (E)-3-(dibenzo[b,d]furan-2-ylmethylene)-6-fluorochroman-4-one (7f) and (E)-3-(dibenzo[b,d] furan-2-ylmethylene)-6-fluorochroman-4-one (7 g) were found to be active with MIC 12.5 μg/mL.

Abstract
Chalcones with or without a para-hydroxyl group were condensed with phenylhydrazine-related compounds to form 1,3,5-triphenyl-1H-pyrazole (TPP), 4-(1,5-diphenyl-1H-pyrazol-3-yl)phenol (APP), 4-(1,3-diphenyl-1H-pyrazol-5-yl)phenol (BPP), and 4-(3,5-diphenyl-1H-pyrazol-1-yl)phenol (CPP), in which the phenyl group formed a dendritic structure with pyrazole as the core. Thus, the aim of this work was to explore the antioxidant capacities of TPP, APP, BPP, and CPP in trapping 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical (ABTS(+•)) and 2,2'-diphenyl-1-picrylhydrazyl radical (DPPH) and in inhibiting Cu(2+)/glutathione (GSH)-, (•)OH-, and 2,2'-azobis(2-amidinopropane hydrochloride) (AAPH)-induced oxidation of DNA. TPP can react with ABTS(+•) and DPPH, indicating that the N atom in pyrazole possesses radical-scavenging ability. Moreover, APP, BPP, and CPP can trap 1.71, 1.81, and 1.58 radicals, respectively, in protecting DNA against AAPH-induced oxidation. Thus, the combination of pyrazole with a phenyl group exerted antioxidant ability although only one phenolic hydroxyl group was involved. However, these compounds showed weak protective effect against Cu(2+)/GSH-induced oxidation of DNA and even a pro-oxidant effect on (•)OH-induced oxidation of DNA.

Ferrocenyl-substituted curcumin: can it influence antioxidant ability to protect DNA? Eur J Med Chem 2011; 46:1821-6. [PMID: 21388716 DOI: 10.1016/j.ejmech.2011.02.041] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2010] [Revised: 02/14/2011] [Accepted: 02/16/2011] [Indexed: 11/23/2022]
Abstract
The antioxidant capacities of ferrocenyl-substituted curcumin derivatives including 1,7-bis(p-hydroxy-m-methoxyphenyl)-4-ferrocenylidene-hepta-1,6-diene-3,5-dione (FCU), 1-(p-hydroxy-m-methoxyphenyl)-3-hydroxy-7-ferrocenyl-hepta-1,4,6-trien-5-one (FFT), and 1-(p-hydroxy-m-methoxyphenyl)-5-ferrocenyl-penta-1,4-dien-3-one (FDZ) were evaluated in 2,2'-azobis(2-amidinopropane hydrochloride) (AAPH), Cu2+/glutathione (GSH), and hydroxyl radical (.OH)-induced oxidation of DNA, and in trapping 2,2'-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical (ABTS+), and galvinoxyl radicals. FCU, FFT, and FDZ protected DNA against Cu2+/GSH-induced oxidation, but promoted .OH-induced oxidation of DNA. FCU, FFT, and FDZ scavenged 9.5, 5.7, and 4.7 radicals in protecting DNA against AAPH-induced oxidation. FCU can trap more DPPH and ABTS+ than FDZ and FFT, whereas FCU, FFT, and FDZ cannot react with galvinoxyl radical. Both phenolic hydroxyl groups and iron atom in ferrocenylidene curcumin derivatives play antioxidant role in this case.

Abstract
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 Cu(2+)/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.
