Abstract
Secondary plant metabolites and their derivatives play a significant role in human health. Ferruginol is a diterpene phenol that has recently received attention for its pharmacological properties, including antibacterial, antitumor, antimalarial, and cardioprotective effects. Recently, we detected the ferruginol compound in the leaf and seed extracts of Juniperus procera using different analytical approaches. The present work aims at detecting phytochemical compounds in a root extract of J. procera and estimating the amount of ferruginol compound in different parts of Juniperus procera. To screen the phytochemical compounds present in the root extract of J. procera, Gas chromatography/mass spectrometry (GC/MS) was performed. For ferruginol identification and estimation, high-performance liquid chromatography (HPLC) with the ferruginol reference standard and high-resolution direct analysis in real-time (DART) time-of-flight mass spectrometry (TOFMS) (DART-TOF-MS) analysis were used. GC/MS analysis revealed more than 20 bioactive compounds related to secondary plant metabolites in the root extract of J. procera with biological activity. The DART-TOF-MS result showed the typical positive ion spectra of ferruginol, and the HPLC result confirmed that the root extract of J. procera contains the ferruginol compound. In contrast, the root extract of J. procera contained a significant amount of ferruginol compared to that in the leaf and seed extracts. All parts of the J. procera contained the ferruginol compound and proved that ferruginol might be accumulated in the roots, leaves, and seeds of J. procera.

Irtegun Kandemir S, Fidan HS, Yener I, Mete N, Ertas A, Topcu G, Kolak U. Investigation of cytotoxic and apoptotic effects of 63 compounds obtained from Salvia species: Promising anticancer agents. J Food Biochem 2022; 46:e14226. [PMID: 35608363 DOI: 10.1111/jfbc.14226] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 03/24/2022] [Accepted: 04/08/2022] [Indexed: 12/22/2022]
Abstract
Since ancient time, Salvia L. species have been commonly used to treat colds, bronchitis, tuberculosis, heart diseases, and menstrual and digestive disorders in traditional medicine all around the world. They have been also used as tea and spice. Studies indicated that diterpenes and triterpenes isolated from Salvia species possess various pharmacological and biological effects such as anti-inflammatory, antiviral, cytotoxic, antioxidant, and hepatotoxic activities. Flavones were also shown to have antimicrobial, antioxidant, and cytotoxic potentials. Salvia extracts also exhibit anti-Alzheimer, antiseptic, cardiovascular, antihypertensive, and antituberculous effects. To investigate the effects of 63 secondary metabolites from Salvia species on cell viability and apoptosis, Salvia secondary metabolites including 25 phenolics, 4 fatty acids, 19 abietane diterpenoids, 12 triterpenoids, and three steroids were examined on healthy cell line (PDF), breast cancer (MCF-7), and colon cancer (HT-29) cell lines using MTT method. In addition, the effects of rosmarinic acid, 6,7-dehydroroyleanone, acetyl royleanone, ferruginol, carnosic acid, carnosol, cryptotanshinone, β-sitosterol, and ursolic acid on pro-apoptotic Bax and antiapoptotic Bcl-2 protein expression levels were investigated by Western Blot method. PRACTICAL APPLICATIONS: Phenolic compounds (apigenin, chrysin, and luteolin) and diterpenes (especially dihydrotanshinone I, carnosic acid, and carnosol), and almost all of the triterpenes exhibited high toxic effects on healthy cell line. Cytotoxic effects of cryptotanshinone, 12-hydroxy abieta-1,3,5(10),8,11,13-hexaene, 12-demethylmulticauline, 6,7-dehydroroyleanone, acetyl royleanone, ferruginol, ursolic acid, and 3-acetyl lupeol were relatively higher than their toxic effects. Acetyl royleanone, 6,7-dehydroroyleanone, carnosic acid, and cryptotanshinone were found to have anticancer potential based on their modulating effects on the expression levels of Bax and Bcl-2 proteins which play important roles in the regulation of apoptosis. The results of the present study showed that acetyl royleanone, cryptotanshinone, 6,7-dehydroroyleanone, carnosic acid, and cryptotanshinone have potential to be used in the pharmaceutical industry.

Abstract
Ethnopharmacological Relevance: Plectranthus genus (Lamiaceae family) contain several species with acknowledged ethnopharmacological uses, such as, for gastrointestinal and respiratory-related problems, due to their anti-inflammatory, antibacterial and antifungal properties. The bioactivity of isolated medicinal compounds from this genus justifies the increased interest in recent times for species of Plectranthus, placing them in the spotlight for natural product drug development. Aim of the study: To the best of our knowledge, this is the first review on the biological activities of Plectranthus ecklonii Benth. As such, the aim of this review was three-fold: 1) to summarize the chemical compounds isolated from P. ecklonii; 2) to collate the biological activities and mechanisms of action of these compounds from in vitro studies; and 3) to evaluate the documented uses and potential applications of this species, in order to postulate on the direction of pharmaceutical uses of this species. Materials and methods: An extensive database retrieval was performed using the electronic databases Web of Science, PubMed, Google Scholar and ScienceDirect. The search criteria consisted of the keywords "Plectranthus ecklonii", "Plectranthus ecklonii + review", "Plectranthus ecklonii + diterpenes" or "Plectranthus ecklonii + abietanes", "ecklonii + parviflorone D", searched individually and as combinations. Eligibility criteria were set out and titles in English, Portuguese and Spanish were reviewed, with all references included dating from 1970 to 2021. A total of 169 papers were selected and included. Chemical structures were drawn using ChemDraw 20.0, CID numbers were searched in PubChem and the PRISMA diagram was created using PowerPoint 2012. Results: To date, a total of 28 compounds have been isolated from P. ecklonii, including diterpenes, triterpenes, flavonoids, and hydroxycinnamic acids. Most focused on the antimicrobial action of its constituents, although compounds have demonstrated other bioactivities, namely antioxidant, anti-inflammatory and antitumor. The most recent studies emphasize the diterpenoids, particularly parviflorone D, with the help of nanotechnology. Conclusions: The widespread ethnobotanical and traditional uses of P. ecklonii can be scientifically justified by a range of biological activities, demonstrated by isolated secondary metabolites. These bioactivities showcase the potential of this species in the development of economically important active pharmaceutical ingredients, particularly in anticancer therapy.

Abstract
Several coronaviruses (CoVs) have been associated with serious health hazards in recent decades, resulting in the deaths of thousands around the globe. The recent coronavirus pandemic has emphasized the importance of discovering novel and effective antiviral medicines as quickly as possible to prevent more loss of human lives. Positive-sense RNA viruses with group spikes protruding from their surfaces and an abnormally large RNA genome enclose CoVs. CoVs have already been related to a range of respiratory infectious diseases possibly fatal to humans, such as MERS, SARS, and the current COVID-19 outbreak. As a result, effective prevention, treatment, and medications against human coronavirus (HCoV) is urgently needed. In recent years, many natural substances have been discovered with a variety of biological significance, including antiviral properties. Throughout this work, we reviewed a wide range of natural substances that interrupt the life cycles for MERS and SARS, as well as their potential application in the treatment of COVID-19.

Determination of fingerprints contents of different extracts and parts of six endemic Salvia taxa by GC-MS: Source species for valuable compounds with drug or drug potential. Biomed Chromatogr 2021; 36:e5263. [PMID: 34647633 DOI: 10.1002/bmc.5263] [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: 06/15/2021] [Revised: 09/30/2021] [Accepted: 10/04/2021] [Indexed: 11/09/2022]
Abstract
Public use of Salvia species and their importance in the scientific world is continually increasing. It is known that this use and the importance of Salvia species are mostly due to the terpenoid compounds that they contain. In this context, the terpenoid-steroid-flavonoid contents of extracts of six endemic Salvia (S. kurdica, S. pseudeuphratica, S. rosifolia, S. siirtica, S. cerino-pruinosa var. cerino-pruinosa and S. cerino-pruinosa var. elazigensis) species prepared with different solvents were determined by gas chromatography-mass spectrometry. Within the framework of the ingredient analysis, content analysis of the ethanol extracts of the root, branch, leaf and flower parts of the species collected in the same period between 2015 and 2017 years was performed. In general, extracts prepared with chloroform and ethanol were found to contain a wide variety of compounds while petroleum ether extracts were found to contain much less varied compounds. In addition, in general, root extracts are richer in terpenoid compounds than aerial part extracts. Some species can be used as source species in terms of ferruginol, cryptanol, 6,7-dehydroroyleanone, lup-(20)29-ene-2α-hydroxy-3β-acetate, salvigenin and β-sitosterol contents (52,114.28, 75,979.08, 101,247.41, 40,071.29, 33,952.13 and 34,010.90 μg analyte/g extract, respectively).

Abstract
In the present study, a GC-MS method used for quantitative screening of 26 compounds (sclareolide, sclareol, ferruginol, cryptanol, 6,7-dehydroroyleanone, suginal, 9,10-dihydro-7,8-dimethyl-2-(1-methylethyl) phenanthren-3-ol, sugiol, inuroyleanone, 12-demethylmulticauline, 7α-hydroxy-β-sitosterol, stigmasterol, sitosterol, salvigenin, sinensetin, α-amyrin, lupeol, lupenone, 3-acetyl lupeol, 1α,21α-dihydroxy-2,3-(1'1'-dimethyl-dioxymethylene) urs-9(11),12-dien, uvaol, betulin, pyxinol, lup-(20),29-ene-2α-hydroxy-3β-acetate, betulin 3β, 28β-diacetate, 21α-hydroxy,2α,3β-diacetoxy urs-9(11),12-dien) specific to Turkish Salvia species was developed and validated. According to the GC-MS analysis results, Salvia hypargeia Fisch. & C.A. Mey. roots were found to be rich in ferruginol (30787.97 µg/g extract) and lupenone (23276.21 µg/g extract), and leaves in lupeol (20625.92 µg/g extract). Additionally, the essential oil and aroma contents of this species were identified by GC-MS technique. According to the LC-MS/MS results, especially S. hypargeia leaf extract was rich in rosmarinic acid (38035.7 µg/g extract) and isoquercitrin (4136.91 µg/g extract). Furthermore, anticholinesterase, antiurease, antityrosinase and antielastase inhibitory, antioxidant, cytotoxic activities of the ethanol extracts, essential oil, and major components of the species were evaluated. Antioxidant potentials of all extracts of this species were quite high in all studied antioxidant methods. Moreover, butyrylcholinesterase and elastase inhibitory capacities of ferruginol, the major component of S. hypargeia roots, were notable. For these reasons, this species has a high potential for food and pharmaceutical industries. PRACTICAL APPLICATIONS: This new GC-MS method was applied to S. hypargeia Fisch. & C.A. Mey. and it indicated that this species possessed high amount of ferruginol and lupeol, and that this species could be used for their natural sources. According to the results of the activity studies (antioxidant, anticholinesterase, tyrosinase, elastase, and cytotoxic), this method was used to exhibit which compound may be responsible for the activities. This developed and validated method could be easily applied to determine major/active/toxic secondary metabolites of Salvia species which are used and/or could be used in pharmaceutical, cosmetic, and food industries.

Abstract
Several corona viral infections have created serious threats in the last couple of decades claiming the death of thousands of human beings. Recently, corona viral epidemic raised the issue of developing effective antiviral agents at the earliest to prevent further losses. Natural products have always played a crucial role in drug development process against various diseases, which resulted in screening of such agents to combat emergent mutants of corona virus. This review focuses on those natural compounds that showed promising results against corona viruses. Although inhibition of viral replication is often considered as a general mechanism for antiviral activity of most of the natural products, studies have shown that some natural products can interact with key viral proteins that are associated with virulence. In this context, some of the natural products have antiviral activity in the nanomolar concentration (e.g., lycorine, homoharringtonine, silvestrol, ouabain, tylophorine, and 7-methoxycryptopleurine) and could be leads for further drug development on their own or as a template for drug design. In addition, a good number of natural products with anti-corona virus activity are the major constituents of some common dietary supplements, which can be exploited to improve the immunity of the general population in certain epidemics.

Abstract
Previous studies have reported higher biological activity of dehydrorosinamine derivatives. In order to further synthesize novel compounds with higher biological activity, a series of novel compounds containing benzo-azepine structures were synthesized from dehydroabietylamine in good yields in this study. The structures of synthesized compounds were identified by infra red (IR), 1H-NMR, 13C-NMR, and mass spectra (MS) analysis. The antitumor activities of the target compounds against L02 and HepG2 cells were studied. Furthermore, the dehydroabietylamine derivatives were studied on plasmid DNA cleavage activities. The results showed that the synthesized target compound exhibit antitumor and DNA cleavage activities against plasmid DNA (Escherichia coli). Our results further demonstrate the relationship between the chemical structure and biological function of the synthesized compounds.

Abstract
Objective 14-Deoxycoleon U is a natural abietane-type diterpene and exerts an inhibitory effect on tumor cells proliferation, which suggests that 14-Deoxycoleon U may be a potent anti-cancerous lead compound for lung cancer treatment. This study was to evaluate potential of 14-Deoxycoleon U to treat lung adenocarcinoma in vitro and in vivo. Methods In the present study, the cell viability and apoptosis morphology of 14-Deoxycoleon U-treated A549 and LLC cells were explored using cell counting kit-8 assay and Hoechst 33258 staining. Then, the protein expressions about apoptosis, endoplasmic reticulum (ER) stress, autophagy and cell cycle were measured using Western blot. The autophagosome formation of 14-Deoxycoleon U-treated A549 cells was visualized using a confocal microscopy. LLC lung adenocarcinoma model was established. Results The results indicated that 14-Deoxycoleon U significantly inhibited A549 and LLC cell proliferation in a dose-dependent manner via caspase-dependent apoptosis. Furthermore, apoptosis of both cells was mediated by 14-Deoxycoleon U-induced ER stress. In addition, 14-Deoxycoleon U-induced A549 and LLC cell autophagy, thus promoting their death. Moreover, 14-Deoxycoleon U-induced cell cycle arrest in both cells via inhibition of cyclin D3, cyclin-dependent kinase 6, CDC2 and up-regulation of p21. In vivo results showed that administration of 14-Deoxycoleon U significantly suppressed LLC growth and adverse effects of 14-Deoxycoleon U on organs might be lower than of adriamycin. Conclusion Overall, our results demonstrated that 14-Deoxycoleon U represses in vitro and in vivo growth of lung adenocarcinoma through ER stress-mediated apoptosis accompanied by autophagy and cell cycle arrest.

Abstract
The aim of our study is to estimate the hepatoprotective effects of the ethanolic extract of the leaves of Sequoia sempervirens by determination of liver biomarkers (ALT, AST, total bilirubin and albumin in serum) and by histopathological examinations using thioacetamide-induced (TAA) liver injury model. Concurrent administration of ethanolic extracts of S. sempervirens leaves improved the alterations in liver morphology where it was a potent protector of the liver. The potential of L-phenylalanine and silver nitrate as chemical elicitors as well as UV radiation as a physical elicitor on flavonoid production in callus culture of S. sempervirens were emphasized. Murashige and Skoog's medium fortified with phenylalanine and silver nitrate enhanced the production of flavonoids and phenolics. HPLC analysis was performed for qualitative and quantitative estimation of some flavonoid compounds in the produced calli in comparison with the mother plant. This finding highlights the potential use of S. sempervirens in the treatment of liver dysfunction.

Abstract
The title compound, C22H28O3, was prepared by a direct acetyl-ation reaction of naturally occurring totarolenone. The mol-ecule contains three fused rings, which exhibit different conformations. The central ring has a half-chair conformation, while the non-aromatic oxo-substituted ring has a screw-boat conformation. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming sheets parallel to the bc plane. The carbonyl O atoms and the C atom at the 6-position of the cyclo-hexene ring are each disordered over two sets of sites with major occupancy components of 0.63 (7) and 0.793 (14), respectively.

Abstract
Sarsasapogenin, a kind of mainly effective component of Anemarrhena asphodeloides Bunge, possesses good antitumor properties. Two series of new sarsasapogenin derivatives were synthesized and evaluated for their cytotoxicities against three human cancer cell lines (HepG2, A549, MCF-7) using the MTT assay. The structure-activity relationship revealed that the N, N-dimethylamino, pyrrolidinyl, and imidazolyl substituted at the C26 position could increase the antitumor efficacy of the 3-oxo sarsasapogenin series of compounds. Compound 4c with pyrrolidinyl substituted at the C26 position exhibited the greatest cytotoxic activity against MCF-7 cell line (IC50 = 10.66 μM), which was 4.3-fold more potent than sarsasapogenin. Action mechanism investigations showed that 4c could inhibit the colony formation and induce the apoptosis of MCF-7 cells. Further researches showed that a decrease in mitochondrial membrane potential and increases in the expression level of cleaved-PARP and the ratio of Bax/Bcl-2 were observed in MCF-7 cells after treatment with 4c, suggesting that the mitochondrial pathway was involved in the 4c-mediated apoptosis. These results show that compound 4c may serve as a lead for further optimization.

Abstract
Parts of Salvia species such as its flowers and leaves are currently used as a culinary herb and for some medicinal applications. To distinguish the different sage extracts it is necessary to analyze their individual chemical compositions. Their characteristic compounds might be established as markers to differentiate between sage flowers and leaf extracts or to determine the manufacturing technology and storage conditions. Tri-p-coumaroylspermidine can be detected only in flowers and has been described here for Salvia and Lavandula species for the first time. Markers for oxidation processes are the novel compounds salviquinone A and B, which were generated from carnosol by exposure to oxygen. Caffeic acid ethyl ester was established as an indirect marker for the usage of ethanol as extraction solvent. The compounds were identified by LC-QTOF-HRESIMS, LC-MS, NMR, IR, and single-crystal X-ray diffraction after isolation by semipreparative HPLC. Furthermore, sage flower resin showed interesting antibacterial in vitro activities against Gram-positive and Gram-negative bacteria.

Abstract
A series of new quinoxaline derivatives of dehydroabietic acid (DAA) were designed and synthesized as potential antitumor agents. Their structures were characterized by IR, 1H-NMR, 13C-NMR, and MS spectra and elemental analyses. All the new compounds were screened for their in vitro antiproliferative activities against three human cancer cell lines (MCF-7, SMMC-7721 and HeLa) and noncancerous human hepatocyte cells (LO2). A cytotoxic assay manifested that compound 4b showed the most potent cytotoxic activity against the three cancer cell lines, with IC50 values of 1.78 ± 0.36, 0.72 ± 0.09 and 1.08 ± 0.12 μM, respectively, and a substantially lower cytotoxicity to LO2 cells (IC50: 11.09 ± 0.57 μM). Moreover, the cell cycle analysis suggested that compound 4b caused cell cycle arrest of SMMC-7721 cells at the G0/G1 phase. In a Hoechst 33258 staining assay, compound 4b caused considerable morphological changes of the nuclei of SMMC-7721 cells, correlated with cell apoptosis. In addition, an Annexin V-FITC/PI dual staining assay confirmed that compound 4b could induce the apoptosis of SMMC-7721 cells in a dose-dependent manner.

Abstract
A series of DHAA thiourea derivatives containing bisphosphonate moiety were designed and synthesized as potent antitumor agents. Structures of target molecules were confirmed using HR-MS, (1)H NMR and (13)C NMR and they exhibited potent anti-tumor activities against the SK-OV-3, BEL-7404, A549, HCT-116 and NCI-H460 tumor cell lines in vitro. Especially, compound 6e (IC50 = 1.79 ± 0.43 μM) exhibited the best anticancer activity against SK-OV-3 cell line. Its role as an inducer of apoptosis was investigated in this cell line by Annexin-V/PI binding assay and by following its capability for ROS generation, depolarization of mitochondrial transmembrane potential, activation of caspases and expression of pro- and anti-apoptotic proteins. Elevated level of ROS generation, activation of caspase-3, caspase-8, caspase-9, and Fas, higher expression of Bax, lower expression of Bcl-2, and increased level of Bax/Bcl-2 ratio identified 6e as a promising inducer of apoptosis that follows both of the mitochondria dependent pathway and the death receptor-mediated pathway. In addition, the cell cycle analysis indicated that compound 6e caused cell cycle arrest at G1 phase, induced apoptosis and led to cell death by increasing the proportion of sub-G1 cells. Furthermore, molecular docking studies showed that 6e could bind to the ATP pocket sites.

Abstract
AbstractA series of piperazine- and cyclen-conjugated dehydroabietylamine derivatives were synthesized and characterized by 1H NMR, 13C NMR, and HRMS. The in vitro antitumor activities of conjugates 10–13 against MCF-7 and HepG-2 tumor cell lines were evaluated using CCK-8 assay. The results show that the synthesized compounds cause a dose-dependent inhibition of cell proliferation and display different antitumor activities with the IC50 values ranging from 23.56 to 78.92 μm. Moreover, the antitumor activity of conjugate 10 against the MCF-7 cell line is superior to that of the positive control 5-fluorouracil. In addition, flow cytometric assay revealed that the representative conjugate 10 could induce apoptosis in MCF-7 tumor cells in a dose-dependent manner.

Abstract
A series of dehydroabietic acid (DHAA) acyl-thiourea derivatives were designed and synthesized as potent antitumor agents. The in vitro pharmacological screening results revealed that the target compounds exhibited potent cytotoxicity against HeLa, SK-OV-3 and MGC-803 tumor cell lines, while they showed lower cytotoxicity against HL-7702 normal human river cells. Compound 9n (IC50 = 6.58 ± 1.11 μM) exhibited the best antitumor activity against the HeLa cell line and even displayed more potent inhibitory activity than commercial antitumor drug 5-FU (IC50 = 36.58 ± 1.55 μM). The mechanism of representative compound 9n was then studied by acridine orange/ethidium bromide staining, Hoechst 33,258 staining, JC-1 mitochondrial membrane potential staining, TUNEL assay and flow cytometry, which illustrated that this compound could induce apoptosis in HeLa cells. Cell cycle analysis indicated that compound 9n mainly arrested HeLa cells in the S phase stage.

Abstract
Four terpenoid derivatives were examined for their activity against Trypanosoma cruzi. Our results show that two compounds were very active in vitro against both extra- and intracellular forms. These compounds, non-toxic for the host cells, are more effective than the reference drug benznidazole. The capacity to infect cells was negatively affected and the number of amastigotes and trypomastigotes was reduced. A wide range of ultrastructural alterations was found in the epimastigote forms treated with these compounds. Some metabolic changes occurred presumably at the level of succinate and acetate production, perhaps caused by the disturbance of the enzymes involved in sugar metabolism inside the mitochondria. In vivo results were consistent with those observed in vitro. The parasitic load was significantly lower than in the control assay with benznidazole. The effects of these products showed the reduction of the anti-T. cruzi antibodies level during the chronic stage.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Salvia officinalis has been used as a traditional remedy against diabetes in many countries and its glucose-lowering effects have been demonstrated in animal studies. The active compounds and their possible mode of action are still unknown although it has been suggested that diterpenes may be responsible for the anti-diabetic effect of Salvia officinalis. AIM OF THE STUDY To investigate whether the reported anti-diabetic effects of Salvia officinalis are related to activation of the nuclear receptor peroxisome proliferator-activated receptor (PPAR)γ and to identify the bioactive constituents. MATERIALS AND METHODS From a dichloromethane extract of Salvia officinalis able to activate PPARγ several major metabolites were isolated by chromatographic techniques. To assess bioactivity of the isolated metabolites a PPARγ transactivation assay was used. RESULTS Eight diterpenes were isolated and identified including a new abietane diterpene being the epirosmanol ester of 12-O-methyl carnosic acid and 20-hydroxyferruginol, which was isolated from Salvia officinalis for the first time, as well as viridiflorol, oleanolic acid, and α-linolenic acid. 12-O-methyl carnosic acid and α-linolenic acid were able to significantly activate PPARγ whereas the remaining metabolites were either unable to activate PPARγ or yielded insignificant activation. CONCLUSIONS Selected metabolites from Salvia officinalis were able to activate PPARγ and hence, the anti-diabetic activity of this plant could in part be mediated through this nuclear receptor.

Abstract
As part of our search for botanical sources of SARS-CoV 3CL(pro) inhibitors, we selected Torreya nucifera, which is traditionally used as a medicinal plant in Asia. The ethanol extract of T. nucifera leaves exhibited good SARS-CoV 3CL(pro) inhibitory activity (62% at 100μg/mL). Following bioactivity-guided fractionation, eight diterpenoids (1-8) and four biflavonoids (9-12) were isolated and evaluated for SARS-CoV 3CL(pro) inhibition using fluorescence resonance energy transfer analysis. Of these compounds, the biflavone amentoflavone (9) (IC(50)=8.3μM) showed most potent 3CL(pro) inhibitory effect. Three additional authentic flavones (apigenin, luteolin and quercetin) were tested to establish the basic structure-activity relationship of biflavones. Apigenin, luteolin, and quercetin inhibited 3CL(pro) activity with IC(50) values of 280.8, 20.2, and 23.8μM, respectively. Values of binding energy obtained in a molecular docking study supported the results of enzymatic assays. More potent activity appeared to be associated with the presence of an apigenin moiety at position C-3' of flavones, as biflavone had an effect on 3CL(pro) inhibitory activity.

Abstract
Ferruginol, a diterpene phenol, has recently received attention for its extensive pharmacological properties, including anti-tumor, antibacterial, cardio-protective and gastroprotective effects. In the present study, a high-performance liquid chromatographic (HPLC) method was developed for determination of ferruginol in rat plasma and applied for the pharmacokinetics study. The HPLC assay was performed with a VP ODS-C(18) column. The mobile phaseconsisted of methanol and 1% acetic acid solution (90:10, v/v). The flow rate was 1.0 mL/min, and the wavelength was set at 270 nm. This method was linear over the studied range of 0.1-10.0 microg/mL( )for ferruginol. The correlation coefficient was 0.9998. The intra-day and inter-day precisions were better than 4 and 5%, respectively. The extraction recovery and accuracy were greater than 97 and 96%, respectively. The detection limit was 30 ng/mL. The mean maximum concentration of ferruginol in rat plasma was 3.14 microg/mL at 40 min after oral administration at a dose of 20 mg/kg. Ferruginol was absorbed quickly p.o. with t(1/2)ka = 14.86 min and had a high rate of elimination with t(1/2) = 41.73 min. The pharmacokinetic process of ferruginol in rat was well described with a one-compartment model.

Abstract
Eight known abietane-type diterpenes were isolated from the weak acidic fraction of the n-hexane extract from cones of Taxodium distichum, one of the extant, living fossil conifers. They were identified as 6,7-dehydroroyleanone (1), taxodal (2), taxodione (3), salvinolone (4), 14-deoxycoleon U (5), 5,6-dehydrosugiol (6), sandaracopimaric acid (7), and xanthoperol (8). The structures of these compounds were determined by comparison of NMR spectral data with published data. The antitermitic (termicidal and antifeedant) activities of the compounds 1-8 against the subterranean termite, Reticulitermes speratus Kolbe, were evaluated. Compounds 1 and 3 showed potent termicidal activity, and 5 and 8 showed potent antifeedant activity. Compound 1 was found to be one of the representative bioactive compounds in the n-hexane extract of T. distichum cones. Compounds 1-8, with the exception of 7, were oxides of ferruginol (9). Therefore, the presence of various oxidation forms of the abietane-type structure reflects their various bioactivities.

Abstract
A series of novel unsymmetrically N,N'-substituted ureas were synthesized from dehydroabietic acid and their structures were characterized by IR, 1H-NMR, 13C-NMR spectroscopy and single crystal X-ray diffraction. Three six-membered rings of urea 4c exhibited plane, half-chair and chair configurations, respectively. Their cytotoxicity activities against SMMC7721 liver cancer cells were evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) method. The results showed that the title compounds exhibited highly effective cytotoxicity activities against SMMC7721 cells. Their IC50 values are between 8.8 and 14.2 micromol/l. The change of N' substituted groups resulted little difference to the cytotoxicity activities of ureas, which indicated that the cytotoxicity of this kind of ureas depend strongly on the tricyclic hydrophenanthrene structure.

Anthraquinones, physcion (1), emodin (2), and questin (3), inhibited the enzymatic activity of Cdc25B phosphatase with IC(50) values of 62.5, 30, and 34 microg mL(-1), respectively. Emodin (2) and questin (3) strongly inhibited the growth of human colon cancer cells, SW620 with GI(50) values of 6.1 and 0.9 microg mL(-1), respectively. Commercially available anthraquinones, chrysophanol (4), and rhein (5) also inhibited Cdc25B phosphatase with IC(50) values of 10.7 and 22.1 microg mL(-1), respectively.

Abstract
Because the activation of matrix metalloproteinases (MMP) is a key factor in the metastatic process, compounds with the ability to inhibit MMP activity have a potential in the treatment of tumor. From the examination of 2000 plant extracts, obovatal isolated from the extract of the leaves of Magnolia obovata THUNB was a potent inhibitor of MMP-2 enzyme in vitro. In human fibrosarcoma cells (HT1080) activated with MMP-2, obovatal inhibited MMP-2 enzyme activity and expression. In addition, the compound blocked migration and invasion of the cells. This study demonstrates that obovatal exerts its anticancer effects through blocking migration and invasion by inhibition of MMP-2 expression and activity, and also will be a good lead molecule for the development of anti-tumor drug.

Abstract
As part of an on-going project to characterize compounds from immature conifer cones with antibacterial or modulatory activity against multidrug-resistant (MDR) strains of Staphylococcus aureus, eight compounds were isolated from the cones of Chamaecyparis lawsoniana. The active compounds were mainly diterpenes, with minimum inhibitory concentrations ranging from 4 to 128 microg/ml against MDR effluxing S. aureus strains and two epidemic methicillin-resistant (EMRSA) clinical isolates. The compounds extracted were the diterpenes ferruginol, pisiferol and its epimer 5-epipisiferol, formosanoxide, trans-communic acid and torulosal, the sesquiterpene oplopanonyl acetate and the germacrane 4beta-hydroxygermacra-1(10)-5-diene. Some of these compounds also exhibited modulatory activity in potentiating antibiotic activity against effluxing strains and ferruginol, used at a sub-inhibitory concentration, resulted in an 80-fold potentiation of oxacillin activity against strain EMRSA-15. An efflux inhibition assay using an S. aureus strain possessing the MDR NorA efflux pump resulted in 40% inhibition of ethidium bromide efflux at 10 microM ferruginol (2.86 microg/ml). We report the (1)H and (13)C NMR data for the cis A/B ring junction epimer of pisiferol which we have named 5-epipisiferol. We also unambiguously assign all (1)H and (13)C NMR resonances for trans-communic acid.

Abstract
A series of beta-amino alcohol analogs of sugiol were synthesized in a straightforward manner. The in vitro antiproliferative activities were examined in the human solid tumor cell lines A2780, SW1573 and WiDr. The most potent analogs induced considerably growth inhibition in the range 1.5-6.7 microM. The results showed that beta-amino alcohol analogs are more potent than the parent compound. In addition, the derivatives with secondary amine fragments showed more active than those bearing tertiary amines.
