Abstract
Coumarin (2H-1-benzopyran-2-one) presents the fundamental structure of an enormous class of biologically active compounds of natural, semi-synthetic, and synthetic origin. Extensive efforts are continually being put into the research and development of coumarin derivatives with medicinal properties by the broad scientific community. Transition metal coordination compounds with potential biological activity are a "hot topic" in the modern search for novel drugs. Complexation with transition metals can enhance the physiological effect of a molecule, modify its safety profile, and even imbue it with novel attributes of interest in the fields of medicine and pharmacy. The present review aims to inform the reader of the latest developments in the search for coumarin transition metal complexes with biological activity, their potential applications, and structure-activity relationships, where such can be elucidated. Each section of the present review addresses a certain kind of biological activity (antiproliferative, antioxidant, antimicrobial, etc.), explores the most recent discoveries in the field, and, at the same time, tries to offer useful perspectives for potential future investigations.

Nie XM, Li YL, Xu XL, Chen FM, Zhang F, Chen D. Application of urea-based magnetic covalent organic framework as sorbent for the determination of coumarin and its derivatives in food samples combined with liquid chromatography-mass spectrometry. Food Chem 2024; 431:137058. [PMID: 37591143 DOI: 10.1016/j.foodchem.2023.137058] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 07/26/2023] [Accepted: 07/28/2023] [Indexed: 08/19/2023]
Abstract
A magnetic solid-phase extraction (MSPE) protocol using novel Urea-based magnetic covalent organic framework coupled with liquid chromatography-mass spectrometry was developed for the detection of coumarins in food samples (soft drink, biscuit and sesame paste). This adsorbent was synthesized through atom economic polymerization of tetrakis(4-aminophenyl) methane and 1,4-phenylene diisocyanate, which was successfully verified by a series of techniques. Major parameters influencing MSPE efficiency were optimized. This protocol had some advantages, such as organic-reagent-saving (2.0 mL), easy operating, short extraction time, and high repeatability (8 times). The established method exhibited superior linearity (R2 ≥ 0.999) and the limits of detection ranging from 1.0 to 5.0 µg/kg. The recoveries of coumarin and its derivatives ranged from 73.8% to 113.5% and both intra- and inter-day precision were less than 15%. These data indicate the protocol is a highly promising alternative for coumarin extraction and enrichment.

Abstract
A series of 3,3-arylidene bis (4-hydroxycoumarins) 2 were synthesized by the reaction of aromatic aldehydes with 4-hydroxycoumarin using dodecylbenzenesulfonic acid as Brønsted acid-surfactant catalyst in aqueous media and under microwave irradiation. The present method is operationally simple and the use of water as the reaction medium makes the process environmentally benign. The epoxydicoumarins 5 were then obtained with a good yield by heating 3,3'-arylidenebis-4-hydroxycoumarins 2 in acetic anhydride. Techniques such as elemental analysis, 1H, 13C-1H NMR, and infrared spectroscopy were employed to characterize these compounds. The synthesized compounds displayed good antibacterial potential against Escherichia coli (ATCC 25988), Pseudomonas aeruginosa (ATCC 27853), Klebsilla pneumonia (ATCC 700603), Staphylococcus aureus (ATCC 29213), methicillin-resistant Staphylococcus aureus (ATCC 43300) and Candida albicans (ATCC 14053). The MIC values of 23 mg/mL for compound 5e against Escherichia coli (ATCC 25988) and 17 mg/mL for 2a were observed. Furthemore, a molecular docking simulation has been performed to evaluate the antibacterial activities and the probable binding modes of the studied compounds 2a-f and 5a-g toward the active sites of a series of well known antibacterial targets. Among the investigated compounds, the binding modes and docking scores demonstrate that 2a has the most antibacterial and antifungal activities. Additionally, DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS has been tested for their ability to scavenge hydrogen peroxide and free radicals. According to our results, these compounds exhibit excellent radical scavenging properties. Furthermore, compounds 2-5 were evaluated for anti-inflammatory activity by indirect haemolytic and lipoxygenase inhibition assays and revealed good activity.

Phenolic Fingerprinting and Bioactivity Profiling of Extracts and Isolated Compounds from Gypothamnium pinifolium Phil. Antioxidants (Basel) 2022; 11:antiox11122313. [PMID: 36552522 PMCID: PMC9774750 DOI: 10.3390/antiox11122313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 11/16/2022] [Accepted: 11/17/2022] [Indexed: 11/24/2022] Open
Abstract
Gypothamnium pinifolium Phil. (Asteraceae) is a small shrub that grows in the Paposo Valley of the II Antofagasta Region of Chile. This initial study is of the high-resolution phenolic fingerprinting, antioxidant activity, the relaxation effects in rat aorta, the inhibitory enzyme potential, plus the antiproliferative activity of the ethyl acetate and n-hexane extract from G. pinifolium and its two major isolated secondary metabolites (one coumarin: 2-nor-1,2-secolycoserone, and one diterpene: ent-labda-8,13-E-diene-15-ol). The study involves using ultra-high-performance liquid chromatography todiode array detection coupled with Q-Orbitrap mass spectrometry analysis (UHPLC-PDA-Orbi-trap-MS), in which various compounds were identified, including specific coumarins. The n-hexane extract showed total phenolic and flavonoid contents of 517.4 ± 12.5 mg GAE/100 g extract and 72.3 ± 3.7 mg QE/100 g extract, respectively. In addition, the antioxidant activity of the n-hexane extract was assessed using in-vitro assays such as bleaching of DPPH and ABTS (IC50: 14.3 ± 0.52 and 2.51 ± 0.43 µg extract/mL, respectively), FRAP (347.12 ± 1.15 μmol Trolox equivalent/g extract), and ORAC (287.3 ± 1.54 μmol Trolox equivalents/g extract). Furthermore, the inhibition against cholinesterases (acetylcholinesterase (AChE) 4.58 ± 0.04 µg/mL, butyrylcholinesterase (BChE) IC50: 23.44 ± 0.03 µg/mL) and tyrosinase (IC50: 9.25 ± 0.15 µg/mL) enzymes of the n-hexane extract, and main compounds (IC50: 1.21 ± 0.03 µg/mL, 11.23 ± 0.02 µg/mL, 3.23 ± 0.12 µg/mL, and 103.43 ± 16.86 µg/mL, correspondingly for the most active coumarin 1) were measured. The antiproliferative potential of the extracts and the two principal compounds against several solid human cancer cells was investigated. All of them showed good activity against cancer cells. Label-free live-cell imaging studies on HeLa cells exposed to the isolated coumarin and the diterpene enabled the observation of cell death and several apoptotic hallmarks. Our results indicate that G. pinifolium Phil. is a valuable source of secondary metabolites with potential activity against noncommunicable diseases.

Abstract
Coumarin derivatives are broadly used as anti-inflammatory, antioxidants, anticancer, and antiviral drugs in recent years. In particular, hydroxy coumarins have great importance because of their various biological and pharmacological purposes. The quantum chemical studies of 4,7-dihydroxycoumarin (DHC) have been performed using the cc-pVTZ level of basis set. The DHC molecular structure has been optimized and the computed frequency assignments have been correlated well with the experimental results. The experimental [Formula: see text]C NMR shifts of DHC have been compared with the computed [Formula: see text]C NMR in the dimethyl sulfoxide (DMSO) solution using the Gauge-invariant atomic orbital (GIAO) method. The electron delocalization within the DHC is shown by highest occupied molecular orbitals (HOMO)-lowest unoccupied molecular orbitals (LUMO) energy analysis, and the resulting small energy gap value reveal the molecule’s bioactive characteristics. The natural bond orbital (NBO) analysis approves the bioactive property of the DHC molecule. The DHC compound has a cytotoxic impact on the MCF-7 breast cancer cell line, according to in vitro cytotoxicity studies. The docking study approves that the DHC works as a new inhibitor of breast cancer targeted proteins such as epidermal growth factor receptor (EGFR), estrogen receptor (ER), and progesterone receptor (PR). Thus, this work covers the approach for the evolution of new drugs against breast cancer.

Abstract
Two newly synthesized 4-hydroxycoumarin bidentate ligands (L1 and L2) and their palladium(II) complexes (C1 and C2) were screened for their biological activities, in vitro and in vivo. Structures of new compounds were established based on elemental analysis, 1H NMR, 13C NMR, and IR spectroscopic techniques. The obtained compounds were tested for their antioxidative and cytotoxic activities and results pointed to selective antiradical activity of palladium(II) complexes towards •OH and -•OOH radicals and anti-ABTS (2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) cation radical) activity comparable to that of ascorbate. Results indicated the effect of C1 and C2 on the enzymatic activity of the antioxidative defense system. In vitro cytotoxicity assay performed on different carcinoma cell lines (HCT166, A375, and MIA PaCa-2), and one healthy fibroblast cell line (MRC-5) showed a cytotoxic effect of both C1 and C2, expressed as a decrease in carcinoma cells' viability, mostly by induction of apoptosis. In vivo toxicity tests performed on zebrafish embryos indicated different effects of C1 and C2, ranging from adverse developmental effect to no toxicity, depending on tested concentration. According to docking studies, both complexes (C1 and C2) showed better inhibitory activity in comparison to other palladium(II) complexes.

Abstract
There are abundant sources of anticancer drugs in nature that have a broad prospect in anticancer drug discovery. Natural compounds, with biological activities extracted from plants and marine and microbial metabolites, have significant antitumor effects, but their mechanisms are various. In addition to providing energy to cells, mitochondria are involved in processes, such as cell differentiation, cell signaling, and cell apoptosis, and they have the ability to regulate cell growth and cell cycle. Summing up recent data on how natural products regulate mitochondria is valuable for the development of anticancer drugs. This review focuses on natural products that have shown antitumor effects via regulating mitochondria. The search was done in PubMed, Web of Science, and Google Scholar databases, over a 5-year period, between 2015 and 2020, with a keyword search that focused on natural products, natural compounds, phytomedicine, Chinese medicine, antitumor, and mitochondria. Many natural products have been studied to have antitumor effects on different cells and can be further processed into useful drugs to treat cancer. In the process of searching for valuable new drugs, natural products such as terpenoids, flavonoids, saponins, alkaloids, coumarins, and quinones cover the broad space.

Abstract
In an attempt to identify suitable nano-carriers for drug delivery, natural drug umbelliferone was chosen to synthesize new modulated nanoconjugate of umbelliferone cobalt oxide with cobalt (II) nitrate in one pot assembly in the presence of tannic acid. The synthesized nanoconjugate drug (NCD) was then loaded on graphene oxide (GO) as drug carrier by simple ultrasonication method and thoroughly characterized by various spectroscopic techniques (FT-IR, SEM, TEM, XRD, EPR and thermogravimetric analysis) which revealed the successful loading of the nanoconjugate drug on GO. The UV-visible, fluorescence and electrochemical studies suggested that strong π-π stacking interactions exist between nanoconjugate drug and GO. The binding studies of NCD-GO with ct-DNA were performed by various optical and biophysical methods viz., UV-visible, fluorescence, circular dichroism (CD) and cyclic voltammetry (CV) which indicated electrostatic mode of binding towards the ct-DNA. Furthermore, condensate of nanoconjugate drug-loaded GO (NCD-GO) with ct-DNA was prepared and analyzed by scanning electron microscopy (SEM) which revealed that the interaction of NCD-GO with ct-DNA had occurred. Cleavage activity of NCD-GO with pBR322 was evaluated by gel electrophoresis and it was found that NCD-GO cleave DNA through hydrolytic pathway involving hydroxyl radical (OH). The cytotoxicity of NCD-GO was evaluated against human liver carcinoma (Huh-7), prostate cancer (Du-145) cell lines along with normal cell line (PNT 2). The results obtained showed selective cytotoxic activity of NCD-GO against Du-145 cell lines. The intracellular uptake was visualized by confocal microscopy which revealed the significant cellular uptake and internalization of nanoparticles by cells. Moreover, the adsorption of cobalt oxide umbelliferone on GO was studied by density functional theory. The process of adsorption was found exothermic in nature and the optimized geometry structure is quite stable. Communicated by Ramaswamy H. Sarma.

Abstract
Avicennia marina is one of the mangrove species used for traditional medicines. The leaves, fruits, and stem barks of A. marina are used for treating skin diseases. The stem barks are used for rheumatism, smallpox, and ulcers. The extract of A. marina was also reported to have antioxidant activity and indicates the presence of alkaloid, saponin, flavonoid, tannin, sterol/triterpenoid, and coumarin. However, the comparison of the antioxidant activity of leaves, fruits, and stem barks is not evaluated yet. The purpose of this study is to compare the antioxidant activity, total phenolic and coumarin content of leaves, fruits, and stem barks of A. marina. The antioxidant activity was determined using DPPH radical scavenging assay and was evaluated by spectrophotometric method at 515 nm. Quercetin was used for comparison. The fruits had the highest antioxidant activity with an IC50 value of 85.246 ppm, followed by stem barks and leaves with IC50 of 205.281 ppm and 307.037 ppm, respectively. Although the antioxidant activity of A. marina fruits was far from quercetin (IC50 of 3.789 ppm), it still categorized as a strong antioxidant. The strong antioxidant activity of fruits was followed by higher total phenolic and coumarin content than the stem barks and leaves part. Total phenolic and coumarin content of fruits were 49.119 mg GAE/ g and 8.894 x 10-3 mg CE/g, respectively. The leaves part had total coumarin content of 8.418 x 10-3 mg CE/g, but it had low IC50. It may be caused by the other secondary metabolite compounds that could reduce the antioxidant activity of coumarin.

Abstract
Cervical cancer remains one of the greatest life threatening diseases for women worldwide. Although chemotherapy is considered as a standard treatment for advanced cervical cancers, there are still some drawbacks in this procedure including side effects and acquired drug resistance, which necessitate further research on development of more effective agents with less side effects. Among natural compounds, coumarin derivatives have shown anticancer properties on various cancerous cells and coumarin ring has proven to have a paramount role in development of anticancer drugs. Here, we aimed to establish the structure-activity relationships of eighteen O-prenylated coumarin derivatives and determined their anticancer properties on HeLa cervical cancer and HDF normal cells by MTT assay. Moreover, the mechanism of cell death induced by these compounds and their effects on cell cycle were studied using flow cytometry. MTT results indicated that twelve O-prenylated coumarin derivatives exhibited selective toxicity on HeLa cells, while they had no significant toxic effects on normal cells. Besides, flow cytometric analyses, showed that the selected compounds induced apoptosis in HeLa cells, and could also result to G1 cell cycle arrest. In conclusion, analyzing structural-activity relationships revealed that a prenylation substitution at position 6 of the coumarin ring greatly improved anticancer properties of these agents. As these derivatives exerted their cytotoxic effects via apoptosis and were not toxic on normal cells, they can be considered as effective anticancer agents for further preclinical experiments.

Abstract
Background This study aimed to investigate the effects of xanthoxyletin, a plant-derived coumarin, on human oral squamous cancer cells in vitro and in mouse xenografts in vivo. Materia/Methods The study included SCC-1 human oral cancer cells and EBTr normal embryonic bovine tracheal epithelial cells, which were treated with 0 μM, 5 μM, 10 μM, and 20 μM of xanthoxyletin for 24 hours. The MTT assay assessed cell viability, and autophagy was detected by electron microscopy. Cell apoptosis was investigated using 4′,6-diamidino-2-phenylindole (DAPI), annexin V, and propidium iodide (PI) fluorescence flow cytometry, which was also used to investigate the cell cycle. Protein expression was measured by Western blot. Mouse xenografts were used for the in vivo evaluation of the effects of xanthoxyletin. Results Xanthoxyletin significantly inhibited the proliferation of oral cancer cells (IC50, 10–30 μM) with lower cytotoxicity for normal cells. Xanthoxyletin treatment was associated with G2/M arrest of the cell cycle and with increased apoptosis and autophagy of SCC-1 cells. Apoptosis and autophagy induced by xanthoxyletin were also associated with changes in expression of the apoptosis-associated proteins, Bax and Bcl-2, and the autophagy-associated proteins, LC3I, LC3II, Beclin 1, p62, and VSp34. Xanthoxyletin inhibited the expression of components of the signaling cascade of the MEK/ERK pathway in the SCC-1 oral cancer cells. The in vivo effects of xanthoxyletin showed inhibition of growth of mouse xenografts. Conclusions Xanthoxyletin inhibited the proliferation of human oral squamous carcinoma cells and induced apoptosis, autophagy, and cell cycle arrest by modulation of the MEK/ERK signaling pathway.

Abstract
We herein report the synthesis and in vitro cytotoxicity of 3-arylcoumarin derivatives (6a-f and 7a-f) in human liver (HepG2), prostate (LNCap), and pancreatic (BxPC3) cancer cell lines. Among the tested compounds, 7,8-dihydroxy-3-(4-nitrophenyl) coumarin (7b) showed the highest cytotoxicity in the HepG2 cell line. The mechanism of cytotoxic action indicated that compound (7b) arrested HepG2 cells at the S phase of the cell cycle progression, induced loss of mitochondrial membrane potential, and caused reactive oxygen species (ROS)-independent cell death. The cell viability result of pretreated HepG2 cells with antioxidant N-acetylcysteine followed by compound (7b) treatment and the free radical scavenging activities of compound (7b) confirmed the ROS-independent cell death. These results demonstrate that compound (7b) could serve as a valuable template for the development of novel synthetic compounds as potential anticancer agents for hepatocellular carcinoma treatment.

Abstract
Coumarins are fused benzene and pyrone ring systems with a wide spectrum of bioactivities, including antitumor, anti-inflammation, antiviral, and antibacterial effects. In this paper, the current development of coumarin-based drugs is introduced, and their structure-activity relationship is discussed by reviewing the relevant literature published in the past 20 years. Coumarin molecules can be customized by the target site to prevent systemic side effects by virtue of structural modification. The ortho-phenolic hydroxyl on the benzene ring has remarkable antioxidant and antitumor activities. Coumarins with aryl groups at the C-4 position have good activities in anti-HIV, antitumor, anti-inflammation, and analgesia. C-3 phenylcoumarins have strong anti-HIV and antioxidant effects. Tetracycline pyranocoumarins can significantly inhibit HIV; osthol structural analogues have antimicrobial activity. Praeruptorin C and its derivatives play an important role in lowering blood pressure and dilating coronary arteries, and khellactone derivatives have significant inhibitory effects on AIDS, cancer, and cardiovascular diseases. It is concluded that the specific site on the core structure of coumarin exhibits one or more activities due to the electronic or steric effects of the substituents. This review is intended to be conducive to rational design and development of more active and less toxic agents with a coumarin scaffold.

Abstract
In continuation of our previous efforts directed towards the development of potent and selective inhibitors of aldose reductase (ALR2), and to control the diabetes mellitus (DM), a chronic metabolic disease, we synthesized novel coumarin-thiazole 6(a-o) and coumarin-oxadiazole 11(a-h) hybrids and screened for their inhibitory activity against aldose reductase (ALR2), for the selectivity against aldehyde reductase (ALR1). Compounds were also screened against ALR1. Among the newly designed compounds, 6c, 11d, and 11g were selective inhibitors of ALR2. Whereas, (E)-3-(2-(2-(2-bromobenzylidene)hydrazinyl)thiazol-4-yl)-2H-chromen-2-one 6c yielded the lowest IC50 value of 0.16±0.06μM for ALR2. Moreover, compounds (E)-3-(2-(2-benzylidenehydrazinyl)thiazol-4-yl)-2H-chromen-2-one (6a; IC50=2.94±1.23μM for ARL1 and 0.12±0.05μM for ARL2) and (E)-3-(2-(2-(1-(4-bromophenyl)ethylidene)hydrazinyl)thiazol-4-yl)-2H-chromen-2-one (6e; IC50=1.71±0.01μM for ARL1 and 0.11±0.001μM for ARL2) were confirmed as dual inhibitors. Furthermore, compounds 6i, 6k, 6m, and 11b were found to be selective inhibitors for ALR1, among which (E)-3-(2-(2-((2-amino-4-chlorophenyl)(phenyl)methylene)hydrazinyl)thiazol-4-yl)-2H-chromen-2-one (6m) was most potent (IC50=0.459±0.001μM). Docking studies performed using X-ray structures of ALR1 and ALR2 with the given synthesized inhibitors showed that coumarinyl thiazole series lacks the carboxylate function that could interact with the anionic binding site being a common ALR1/ALR2 inhibitors trait. Molecular docking study with dual inhibitor 6e also suggested plausible binding modes for the ALR1 and ALR2 enzymes. Hence, the results of this study revealed that coumarinyl thiazole and oxadiazole derivatives could act as potential ALR1/ALR2 inhibitors.

Abstract
Human topoisomerase I (Htopo I) is a vital target for anti-cancer agents; however, available anti-cancer agents are linked with several limitations. Therefore, designing novel inhibitors for Htopo I is significant. The rationale behind the current study is to identify novel coumarin inhibitors for Htopo I using in silico approaches and predict drug leads for in vitro studies. Using molecular docking and molecular dynamics, the binding affinities of 75 coumarins were compared with a known Htopo I inhibitor, topotecan. Docking studies predict three coumarins T1L25, T2L25, and T3L25 as most potent inhibitors for Htopo I. T2L25 gives the best grid score (–295 kJ mol–1), which is very comparable with that of topotecan (–302 kJ mol–1). The binding of these coumarins occurs preferentially via a planar geometry, and ligands bind at the binding site parallel to the axis of base pairing. NHCOCH3-substituted ligands are more favourable for binding when compared with the other substitute groups considered. The binding free energies calculated from molecular mechanics Poisson–Boltzmann surface area (MM-PBSA) method imply that T3L25 possesses the highest binding affinity when compared with the other two ligands. However, T1L25 and T2L25 have comparable binding free energies according to MM-PBSA calculations. Additionally, other calculated properties also support the suitability of these three derivatives as inhibitors for Htopo I. Therefore, the current study theoretically predicts three coumarin derivatives T1L25, T2L25, and T3L25 as potent inhibitors for Htopo I. These findings could lead to exploring novel non-camptothecin inhibitors for Htopo I.

Abstract
AIM To identify a novel coumarin analogue with the highest anticancer activity and to further investigate its anticancer mechanisms. METHODS The viability of cancer cells was investigated using the MTT assay. The cell cycle progression was evaluated using both flow cytometric and Western blotting analysis. Microtubule depolymerization was observed with immunocytochemistry in vivo and a tubulin depolymerization assay in vitro. Apoptosis was demonstrated using Annexin V/Propidium Iodide (PI) double-staining and sub-G(1) analysis. RESULTS Among 36 analogues of coumarin, 6-chloro-4-(methoxyphenyl) coumarin showed the best anticancer activity (IC(50) value about 200 nmol/L) in HCT116 cells. The compound had a broad spectrum of anticancer activity against 9 cancer cell lines derived from colon cancer, breast cancer, liver cancer, cervical cancer, leukemia, epidermoid cancer with IC(50) value of 75 nmol/L-1.57 μmol/L but with low cytotocitity against WI-38 human lung fibroblasts (IC(50) value of 12.128 μmol/L). The compound (0.04-10 μmol/L) induced G(2)-M phase arrest in HeLa cells in a dose-dependent manner, which was reversible after the compound was removed. The compound (10-300 μmol/L) induced the depolymerization of purified porcine tubulin in vitro. Finally, the compound (0.04-2.5 μmol/L) induced apoptosis of HeLa cells in dose- and time-dependent manners. CONCLUSION 6-Chloro-4-(methoxyphenyl) coumarin is a novel microtubule-targeting agent that induces G(2)-M arrest and apoptosis in HeLa cells.

Abstract
The antioxidant activity of 4-hydroxycoumarin synthetic derivatives and 4-methylumbelliferone were determined taking 4-hydroxycoumarin as the reference compound. Six 3-aryl-4-hydroxycoumarin derivatives were synthesized from 4-hydroxycoumarin as precursor in order to evaluate changes in their antioxidant properties due to C3-aryl substituent nature. Free radical scavenging capacities of these compounds against two different species DPPH(·) and ABTS(·+) and the protecting ability towards the β-carotene-linoleic acid co-oxidation enzymatically induced by lipoxygenase were measured. In addition, the relationship between the activities of these molecules against DPPH radical and the bond dissociation energy of O-H (BDE) calculated using methods of computational chemistry was evaluated.

Abstract
We report on the synthesis of 4-hydroxycoumarin dimers 1-15 bearing an aryl substituent on the central linker and fused benzopyranocoumarin derivatives 16-20 and on their in vitro broad anti-DNA and RNA virus activity evaluations. The chemical identities and structure of compounds 1-20 were deduced from their homo- and heteronuclear NMR measurements whereas the conformational properties of 5, 14 and 20 were assessed by the use of 1D difference NOE enhancements. Unequivocal proof of the stereostructure of compounds 7, 9, 16 and 18 was obtained by single crystal X-ray diffraction method. The X-ray crystal structure analysis revealed that two 4-hydroxycoumarin moieties in the 4-trifluoromethylphenyl- and 2-nitrophenyl derivatives (compounds 7 and 9, respectively) are intramolecularly hydrogen-bonded between hydroxyl and carbonyl oxygen atoms. Consequently, the compounds 7 and 9 adopt conformations in which two 4-hydroxy-coumarin moieties are anti-disposed. Antiviral activity evaluation results indicated that the 4-bromobenzylidene derivative of bis-(4-hydroxycoumarin) (compound 3) possesses inhibitory activity against HSV-1 (KOS), HSV-2 (G), vaccinia virus and HSV-1 TK⁻ KOS (ACVr) at a concentration of 9-12 μM and at a minimum cytotoxic concentration (MCC) greater than 20 μM. Compounds 4-6, 8, and 20 were active against feline herpes virus (50% effective concentration, EC₅₀ = 5-8.1 μM), that is at a 4-7-fold lower concentration than the MCC.

Abstract
New La(III) and Dy(III) complexes of deprotonated 4-hydroxy-3[1-(4-nitrophenyl)-3-oxobutyl]-2H-1-benzopyran-2-one (Acenocoumarol) were synthesized and characterized using FT-IR, FT-Raman, (1)H NMR spectra, and elemental analyses. The ligand and its lanthanide(III) complexes were tested for their cytotoxic/cytostatic activity against two tumor cell lines and peritoneal mouse macrophages. The La(III) and Dy(III) complexes exhibit good activity against melanoma B16 and fibrosarcoma L929 and they are stronger inhibitors of tumor cell proliferation compared to the ligand without influencing normal cell viability and NO release by mouse peritoneal macrophages.
