[PMID: 37473689 DOI: 10.1016/j.ejmech.2023.115623] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 06/15/2023] [Accepted: 07/03/2023] [Indexed: 07/22/2023]
Abstract
Topoisomerase II (TopoII) is a critical component of HIV-1 integration, proviral DNA synthesis, and reverse transcription. During HIV-1 infection, the TopoIIβkinase (TopoIIβKHIV-1) phosphorylates TopoIIβ. Our earlier research demonstrated that the pyridine scaffold has potent anti-HIV-1 activity by specifically inhibiting TopoIIβKHIV-1 activity. 3D QSAR results showed the presence of molecular features for interaction with TopoIIβKHIV-1 requiring chemically induced proximity for potential interaction. In this study, the chalcone and methyl groups were added to the pyridine scaffold's core to achieve the desired proximity length between the pyridine scaffold and charged centers, which resulted in an inhibitory activity against TopoIIβKHIV-1 and viral replication. According to the findings, the TopoIIβKHIV-1activity was inhibited by the inclusion of the pyridine scaffold with the chalcone group, leading to better anti-HIV-1 activity. The water-soluble methylated pyridinium chalcones' showed significant TopoIIβKHIV-1 antagonism, anti-HIV-1 activity (from IC50 > 500 nM to ID50 25 nM), and reduced cytotoxicity (CC50 = 2 mM). These activities could be associated with the charge on the pyridine and extended proximity. Therefore, it is clear that within the scope of this work, altering the proximity length and charge centers of pyridine molecules are critical for the design and development of effective anti-HIV-1 leads, specifically targeting TopoIIβKHIV-1.

Abstract
Endogenous estradiol (E2) exerts diverse physiological and pharmacological activities, commonly used for hormone replacement therapy. However, prolonged and excessive exposure to E2 potentially increases estrogenic cancer risk. Reportedly, CYP1 enzyme-mediated biotransformation of E2 is largely concerned with its balance between detoxification and carcinogenic pathways. Among the three key CYP1 enzymes (CYP1A1, CYP1A2, and CYP1B1), CYP1A1 and CYP1A2 mainly catalyze the formation of nontoxic 2-hydroxyestradiol (2-OH-E2), while CYP1B1 specifically catalyzes the formation of genotoxic 4-hydroxyestradiol (4-OH-E2). 4-OH-E2 can be further metabolized to electrophilic quinone intermediates accompanied by the generation of reactive oxygen species (ROS), triggering DNA damage. Since abnormal alterations in CYP1 activities can greatly affect the bioactivation process of E2, regulatory effects of xenobiotics on CYP1s are essential for E2-associated cancer development. To date, thousands of natural and synthetic compounds have been found to show potential inhibition and/or induction actions on the three CYP1 members. Generally, these chemicals share similar planar polycyclic skeletons, the structural motifs and substituent groups of which are important for their inhibitory/inductive efficiency and selectivity toward CYP1 enzymes. This review comprehensively summarizes these known inhibitors and/or inductors of E2-metabolizing CYP1s based on chemical categories and discusses their structure-activity relationships, which would contribute to better understanding of the correlation between xenobiotic-regulated CYP1 activities and estrogenic cancer susceptibility.

The Chemopreventive Effects of Polyphenols and Coffee, Based upon a DMBA Mouse Model with microRNA and mTOR Gene Expression Biomarkers. Cells 2022; 11:cells11081300. [PMID: 35455979 PMCID: PMC9029301 DOI: 10.3390/cells11081300] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 04/08/2022] [Accepted: 04/10/2022] [Indexed: 12/11/2022] Open
Abstract
Polyphenols are capable of decreasing cancer risk. We examined the chemopreventive effects of a green tea (Camellia sinensis) extract, polyphenol extract (a mixture of blackberry (Rubus fruticosus), blackcurrants (Ribes nigrum), and added resveratrol phytoalexin), Chinese bayberry (Myrica rubra) extract, and a coffee (Coffea arabica) extract on 7,12-dimethylbenz[a]anthracene (DMBA) carcinogen-increased miR-134, miR-132, miR-124-1, miR-9-3, and mTOR gene expressions in the liver, spleen, and kidneys of CBA/Ca mice. The elevation was quenched significantly in the organs, except for miR-132 in the liver of the Chinese bayberry extract-consuming group, and miR-132 in the kidneys of the polyphenol-fed group. In the coffee extract-consuming group, only miR-9-3 and mTOR decreased significantly in the liver; also, miR-134 decreased significantly in the spleen, and, additionally, miR-124-1 decreased significantly in the kidney. Our results are supported by literature data, particularly the DMBA generated ROS-induced inflammatory and proliferative signal transducers, such as TNF, IL1, IL6, and NF-κB; as well as oncogenes, namely RAS and MYC. The examined chemopreventive agents, besides the obvious antioxidant and anti-inflammatory effects, mainly blocked the mentioned DMBA-activated factors and the mitogen-activated protein kinase (MAPK) as well, and, at the same time, induced PTEN as well as SIRT tumor suppressor genes.

Abstract
Substitution by the CF3S group allows for an increase in lipophilicity and electron-withdrawing properties along with an improvement in the bioavailability of medicinal targets; consequently, the late stage introduction of CF3S moieties into medicinal scaffolds is a sought-after strategy in synthetic organic chemistry. Different newly-developed electrophilic and nucleophilic reagents are used to effect the trifluoromethylthiolation of (hetero)aromatic compounds, aliphatic compounds (alkyl, alkenyl, alkynyl substrates), the trifluoromethylthiolation at the α- and β-carbonyl positions, and heteroatoms (N- and S-). Such reactions can involve homolytic substitutions, or functional-group substitutions (ipso). Addition reactions of electrophilic reagents to double and triple bonds followed by ring-cyclizations will be shown to yield relevant CF3S-substituted heteroaromatic compounds with relevant pharmacological action.

Abstract
Abstract
Crystal structures are reported from data collected at 100 K of (E)-2-(X-benzylidene)-1-tetralone (2: X=3-O2N; 3: X=4-O2N; 5: X=4-HO; 6: X=4-Me2N; 7: 4-NC), (E)-2-(X-benzylidene)-6-MeO-1-tetralone, 8, and (E)-2-(X-benzylidene)-5-MeO-1-tetralone 9. Also reported herein are the Hirshfeld surface calculations for these compounds as well as those of (E)-2-(X-benzylidene)-1-tetralone (1: X=H; 4: X=4-MeO), whose structures were previously reported. The molecules are not planar as shown by the dihedral angles of 45.66(5)–69.78(5)° between the phenyl groups and by the puckered cyclohexenyl rings. A common feature of the molecular conformations is the C–H···O1(carbonyl) intramolecular hydrogen bond. The carbonyl oxygen atom plays significant roles in the interactions in all compounds baring compound 8. However, there is no consistent set of intermolecular interaction in this group of compounds. Intermolecular interactions present in each compound are some of the O–H···O, C–H···A (A=O, N or π), A–O···π (A=C or N) and π···π interactions. The only compound exhibiting a classical O–H···O hydrogen bond is compound 5. C–H···π interactions are found in all compounds, and while π···π interactions are present in compounds 2, 3, 7 and 9, no consistent type of stacking arrangement is shown. The Hirshfeld surface calculations, while generally concurring with the intermolecular interactions indicated by PLATON analyses, also reveal short interactions, which fall below the PLATON cut-off parameters.

Abstract
Crystal structures are reported of (E)-2-(4-hydroxybenzylidene)-2,3-dihydro-1H-inden-1-one, 1, (E)-2-(4-dimethylaminobenzylidene)-2,3- dihydro-1H-inden-1-one, 2, (E)-2-(4-cyanobenzylidene)-2,3-dihydro-1H-inden-1-one, 3, and monoclinic-(E)- 2-(3-nitrobenzylidene)-2,3-dihydro-1H-inden-1-one, monoclinic-4, all from data collected at 100 K and (E)-2-(4-hydroxy-3,5-dimethylbenzylidene)-2,3-dihydro-1H-indan-1-one, 6, from data collected at 299 K. An earlier triclinic form of 4 has been reported. Also reported herein are the Hirshfeld suface calculations for these five compounds, as well as that of 2-(4-methoxybenzylidene)-2,3-dihydro-1H-inden-1-one, 5,whose crystal structure has been previously reported. The three rings in each of the compounds, 1–4 and 6, are essentially planar, including the five-membered ring containing a formally hydridized sp3 atom. The molecules exhibit slight deviations from overall planarity as shown by the dihedral angles, >8.15(6)° between the 2,3-dihydro-1H-inden-1-one fragments and the phenyl fragments. The main intermolecular interactions in compounds 1 and are classical O–H···O1(carbonyl) hydrogen bonds. The carbonyl oxygen atom in compounds 1–4 are involved in non-classical C–H···O intermolecular hydrogen bonds. Intermolecular C–H---π interactions are present in 2, 3 and 6, while π···π are present in 2–4 and 6. As noted in the structure determinations of these compounds, different π···π motifs are possible. The Hirshfeld surface calculations, while generally concurring with the intermolecular interactions indicated by PLATON analyses, also reveal significant interactions, which fall below the PLATON radar.

Abstract
Chalcones are intermediary compounds of the biosynthetic pathway of the naturally flavonoids. Previous studies have demonstrated that chalcones and their conformationally rigid cyclic analogues have tumour cell cytotoxic and chemopreventive effects. It has been shown that equitoxic doses of the two cyclic chalcone analogues (E)-2-(4'-methoxybenzylidene)-(2) and (E)-2-(4'-methylbenzylidene)-1-benzosuberone (3) have different effect on cell cycle progress of the investigated Jurkat cells. It was also found that the compounds affect the cellular thiol status of the treated cells and show intrinsic (non-enzyme-catalyzed) reactivity towards GSH under cell-free conditions. In order to gain new insights into the cytotoxic mechanism of the compounds, effects on the redox status and glutathione level of Jurkat cells were investigated. Detection of intracellular ROS level in Jurkat cells exposed to 2 and 3 was performed using the dichlorofluorescein-assay. Compound 2 did not influence ROS activity either on 1 or 4h exposure; in contrast, chalcone 3 showed to reduce ROS level at both timepoints. The two compounds had different effects on cellular glutathione status as well. Compound 2 significantly increased the oxidized glutathione (GSSG) level showing an interference with the cellular antioxidant defence. On the contrary, chalcone 3 enhanced the reduced glutathione level, indicating enhanced cellular antioxidant activity. To investigate the chalcone-GSH conjugation reactions under cellular conditions, a combination of a RP-HPLC method with electrospray ionization mass spectrometry (ESI-MS) was performed. Chalcone-GSH adducts could not be observed either in the cell supernatant or the cell sediment after deproteinization. The investigations provide further details of dual - cytotoxic and chemopreventive - effects of the cyclic chalcone analogues.

Cytochrome P450 family 1 inhibitors and structure-activity relationships. Molecules 2013; 18:14470-95.

Abstract
With the widespread use of O-alkoxyresorufin dealkylation assays since the 1990s, thousands of inhibitors of cytochrome P450 family 1 enzymes (P450s 1A1, 1A2, and 1B1) have been identified and studied. Generally, planar polycyclic molecules such as polycyclic aromatic hydrocarbons, stilbenoids, and flavonoids are considered to potentially be effective inhibitors of these enzymes, however, the details of the structure-activity relationships and selectivity of these inhibitors are still ambiguous. In this review, we thoroughly discuss the selectivity of many representative P450 family 1 inhibitors reported in the past 20 years through a meta-analysis.

Comparison of structure, logP and P388 cytotoxicity of some phenyl and ferrocenyl cyclic chalcone analogues. Application of RP-TLC for logP determination of the ferrocenyl analogues. OPEN CHEM 2012.

Abstract
AbstractCyclic chalcone analogues (2–5) and their ferrocenyl counterparts (6–10) were synthesized and their logP and P388 cyctotoxity were investigated. The structures of the newly synthesized compounds were confirmed by IR 1H and 13NMR spectroscopy. Comparison of conjugation and stereochemistry of the respective derivatives showed similar characteristics compared to ones with some higher degree of conjugation in the ferrocenyl series. Comparison of logP of the ferrocenyl derivatives determined by a validated RP-TLC method showed the ferrocenyl derivatives to have higher logP TLC. The results demonstrate that the differences in three dimensional shape, conjugation and lipophilicity do not have strong influence on the P388 cytotoxicity of the investigated phenyl (1−5) and ferrocenyl (6−10) enones.

Abstract
A series of chalcone derivatives (1-4) were studied. The interaction between these ligands and calf thymus DNA was studied with UV-vis spectrophotometry, fluorescence and circular dichroism spectroscopy. The binding constants K were estimated at 0.5-4.6×10(5) M(-1). All these measurements indicated that the compounds behave as effective DNA-intercalating agents. Electrophoretic separation proved that ligands inhibited topoisomerase I at a concentration of 60 μM.

Abstract
Forty-four novel chalcone-inspired analogs having a 3-aryl-2-propenoyl moiety derived from alicyclic ketones were designed, synthesized, and investigated for cytotoxicity against murine B16 and L1210 cancer cell lines. The analogs belong to four structurally divergent series, three of which (series g, h, and i) contain differently substituted cyclopentanone units and the fourth (series j) contains a 3,3-dimethyl-4-piperidinone moiety. Of these, the analogs in series j showed potential cytotoxic activity against murine B16 (melanoma) and L1210 (lymphoma) cells. The most active compounds 5j, 11j, 15j, and 12h produced IC(50) values from 4.4 to 15 μm against both cell lines. A single-crystal X-ray structure analysis and molecular modeling studies confirmed that these chalcones have an E-geometry about the alkene bond and possess a slightly 'twisted' conformation similar to that of combretastatin A-4. At a concentration of 30 μm, compounds 5j, 11j, and 15j did not cause microtubule depolymerization in cells, suggesting that they have a different mechanism of action.

Abstract
Investigation of in vitro hydroxyl radical scavenging (antioxidant) effect 4-methoxychalcone (1a) and its cyclic analogues (2a-4a), as well as their hydroxyl substituted counterparts (1b-4b) was performed by means of the Fenton-reaction initiated deoxyribose degradation assay in short term (10 minute) and long term (240 minute) experiments. The kinetic deoxyribose method provides possibility to investigate not only the short term antioxidant (hydroxyl radical scavenger) effect but the possible late prooxidant effect of the tested substances as well. In the short term studies compounds 2a, 2b and 4b showed the most pronounced antioxidant effect. The long-term studies showed that the antioxidant activity of all the tested compounds but 4a can be well characterized by the short time determination of the thiobarbituric acid (TBA)-reactive substances (TBARS). Experiments in the presence of ethylenediaminetetraacetic acid (EDTA) resulted in a substantially reduced degradation of deoxyribose in each incubation. Similar to the respective experiment performed without EDTA, the TBARS level of the incubations with 4a showed an increase over the 60-120 minute period. The results demonstrated that complex forming activities that can modify microspeciation and reactivity of iron ions can lead to different short term antioxidant efficiency of the tested substances. Results of the long term incubations indicated that chemical transformation of the tested substances can result formation of derivatives that can initiate further redox activities under the experimental conditions.

Abstract
1. PAP-1 (5-(4-phenoxybutoxy)psoralen), a potent small-molecule blocker of the voltage-gated potassium Kv1.3 channel, is currently in preclinical development for psoriasis. This study was undertaken to identify the major phase I metabolites of PAP-1 in Sprague-Dawley (SD) rats. 2. Five phase I metabolites, that is 5-(oxybutyric-acid)psoralen (M1), 5-[4-(4-hydroxybutoxy)]psoralen (M2), 5-[4-(4-hydroxyphenoxy)butoxy]psoralen (M3), 5-[4-(3-hydroxyphenoxy)butoxy]psoralen (M4), and 8-hydroxyl-5-(4-phenoxybutoxy)psoralen (M5), were isolated from the bile of rats and identified by mass spectrometry and NMR spectroscopy. The last four metabolites are new compounds. 3. Incubation of PAP-1 with SD rat liver microsomes rendered the same five major metabolites in a nicotinamide adenine dinucleotide phosphate (NADPH)-dependent manner suggesting that cytochrome P450 (CYP) enzymes are involved in PAP-1 metabolism. Inhibitors of rat CYP1A1/2 (alpha-naphthoflavone) and CYP3A (ketoconazole) but not CYP2D6 (quinidine), CYP2E (diethyldithiocarbamate), or CYP2C9 (sulphaphenazole) blocked the metabolism of PAP-1 in rat microsomes. 4. Of the five metabolites M3, M4, and M5 were found to inhibit Kv1.3 currents with nanomolar IC50s, while M1 and M2 were inactive. Our results identified the Kv1.3-inactive M1 as the major phase I metabolite, and suggest that hydroxylation and O-dealkylation are the major pathways of PAP-1 metabolism. 5. We further conducted a 6-month repeat-dose toxicity study with PAP-1 at 50 mg/kg in both male and female Lewis rats and did not observe any toxic effects.

Abstract
We investigated the effect of hydroxyl substituted chalcone (1a) and some chalcone analogues (1b-d) on isolated rat liver mitochondria to gain new insights into the cytotoxic mechanism of these compounds. We observed an inhibitory effect on phosphorylation and the partial uncoupling of compounds 1a and 1d. Increased radical generation and possible covalent interaction of the compounds with cellular thiols resulted in glutathione (GSH) depletion and modulation of the investigated mitochondrial activities. Disruption of interconnected mechanisms as electron transport chain and energetic metabolism, ROS production and insufficiency of antioxidant defensive system could lead to induction of cell death.

Abstract
It has been previously shown that the cyclic chalcone analogues E-2-(4'-methoxybenzylidene)- (2) and E-2-(4'-methylbenzylidene)-1-benzusuberone (3) inhibited proliferation of various murine and human tumor cells. In order to gain new insights into the cytotoxic mechanism of the two compounds detection of apoptosis and necrosis of Jurkat T cells exposed to 2 and 3 were performed by flow cytometry using the Annexin V-FITC and propidium iodide double staining method. Analysis of the DNA histograms at 8, 24 and 48 h exposure times showed that near equitoxic doses of 2 and 3 had different effects on the cell cycle of the exposed cells. The immediate (8h) effect of 2 was a remarkable decrease of cells in the G(0)/G(1) phase and increase in the G(2)/M phase. This effect could also be seen in the histogram of cells at the 24h time point. On the contrary, such an effect of 3 could not be observed. At the 24 and 48 h time points accumulation of sub-G(0) (apoptotic and necrotic) and hyperdiploid cells could be detected after both treatments. Incubation of 2 and 3 with reduced glutathione under cell-free conditions indicated spontaneous conjugation (non-redox) reaction at pH 7.4 and pH 9.0. Analyzing the mechanism of action the total thiol content of the cells exposed to compounds 2 and 3 was determined. Compound 2 showed to reduce the total cellular thiol level both under nutrient-free and nutrient-supplemented conditions. Under the latter conditions an increase of the total thiol level of the cells exposed to 3 for 4h could be observed. The different effect of the two compounds on the cellular thiol status might contribute to the different tumor cytotoxicity of the cyclic chalcone analogues 2 and 3. Investigation of antioxidant capacity of the compounds by monitoring time course of the Fenton-reaction initiated in vitro degradation of 2-deoxyribose indicated that both compounds displayed hydroxyl radical scavenger activity. The experiments provide further details of dual--cytotoxic and cytoprotective (chemopreventive)--effects of the compounds.

Abstract
Chalcones are phenolic compounds that can be isolated from plants. Previous studies have described some pharmacological applications for these compounds. Making use of our established reporter gene system, we determined the effect of five hydroxychalcones--2-hydroxychalcone, 2'-hydroxychalcone, 4-hydroxychalcone, 4,2',4'-trihydroxychalcone, and 3,4,2',4'-tetrahydroxychalcone--on the cellular xenobiotic responsive element (XRE)-transactivation. The interference of chalcones acting against polycyclic aromatic hydrocarbon (PAH)-DNA binding was also examined. Enzyme inhibition assays of cytochrome P450 (CYP) 1A1 and CYP1B1 were initially performed on recombinant protein expressed in insect microsomes. 2'-Hydroxychalcone and 2-hydroxychalcone were the most effective among the tested hydroxychalcones. The two hydroxychalcones had comparable IC50 values for CYP1A1 and CYP1B1, which were determined to be at the micromolar and submicromolar range, respectively. However, reporter gene assays indicated that 2'-hydroxychalcone suppressed XRE-transactivation, whereas 2-hydroxychalcone induced it when 7,12-dimethylbenz[a]anthracene (DMBA) was co-administered. In the absence of DMBA, 10 microM 2-hydroxychalcone and 2'-hydroxychalcone increased XRE-transactivation by 18- and 2.5-fold, respectively, while other chalcones did not significantly alter the response. Cultures treated with the two hydroxychalcones also displayed separate trends in ethoxyresorufin-O-deethylase (EROD) activity and DMBA-DNA covalent binding. In summary, the present study illustrated that the inhibition of hydroxychalcone on CYP1 enzymes and XRE-transactivation was affected by the position and number of hydroxyl groups in its structure.
