Synthesis of eperezolid-like molecules and evaluation of their antimicrobial activities

3-Fluoro-4-(4-phenylpiperazin-l-yl)aniline (II) prepared from 3,4-difluoro nitrobenzene was converted to the corresponding Schiff bases (III) and (IV) by treatment with 4-methoxybenzaldehyde and indol-3-carbaldehyde, respectively. Treatment of amine (II) with 4-fluorophenyl isothiocyanate afforded the corresponding thiourea derivative (V). Compound (V) was converted to thiazolidinone and thiazoline derivatives (VI) and (VII) by cyclocondensation with ethylbromoacetate or 4-chlorophenacylbromide, respectively. The synthesis of carbothioamide derivative (X) was performed starting from compound (II) by three steps. Treatment of compound (X) with sodium hydroxide, sulfuric acid, or chlorophenacyl bromide generated the corresponding 1,2,4-triazole (XI), 1,3,4-thiadiazole (XII), and 1,3-thiazolidinone (XIII) derivatives, respectively. The structural assignments of new compounds were based on their elemental analysis and spectral (IR, ¹H-NMR, ¹³C-NMR, and LC-MS) data. In the antimicrobial activity study all the compounds revealed high anti-Mycobacterium smegmatis activity.     

Synthesis of Pyrrolo[2′,3′:4,5]Furo[3,2-c]Pyridine-2-Carboxylic Acids

1H-Pyrrolo[2′,3′:4,5]furo[3,2-c]pyridine-2-carboxylic acid (6a) and its 1-methyl (6b) and 1-benzyl (6c) derivatives were synthesized. 3-(5-Methoxycarbonyl-4H-furo[3,2-b]-pyrrole-2-yl)propenoic acid (1) was converted to the corresponding azide 2, which in turn was cyclized to give 3 by heating in diphenylether. The pyridone 3 obtained was aromatized with phosphorus oxychloride, then reduced with zinc in acetic acid to give methyl 1H-pyrrolo[2′,3′:4,5]furo[3,2-c]pyridine-2-carboxylate (5), which by hydrolysis gave the corresponding carboxylic acid 6a.     

N(4)-Tolyl-2-acetylpyridine thiosemicarbazones and their platinum(II,IV) and gold(III) complexes: cytotoxicity against human glioma cells and studies on the mode of action

Complexes [Au(2Ac4oT)Cl][AuCl₂] (1), [Au(H_py2Ac4mT)Cl₂]Cl·H₂O (2), [Au(H_py2Ac4pT)Cl₂]Cl (3), [Pt(H2Ac4oT)Cl]Cl (4), [Pt(2Ac4mT)Cl]·H₂O (5), [Pt(2Ac4pT)Cl] (6) and [Pt(L)Cl₂OH], L = 2Ac4mT (7), 2Ac4oT (8), 2Ac4pT (9) were prepared with N(4)-ortho- (H2Ac4oT), N(4)-meta- (H2Ac4mT) and N(4)-para- (H2Ac4pT) tolyl-2-acetylpyridine thiosemicarbazone. The cytotoxic activities of all compounds were assayed against U-87 and T-98 human malignant glioma cell lines. Upon coordination cytotoxicity improved in 2, 5 and 8. In general, the gold(III) complexes were more cytotoxic than those with platinum(II,IV). Several of these compounds proved to be more active than cisplatin and auranofin used as controls. The gold(III) complexes probably act by inhibiting the activity of thioredoxin reductase enzyme whereas the mode of action of the platinum(II,IV) complexes involves binding to DNA. Cells treated with the studied compounds presented morphological changes such as cell shrinkage and blebs formation, which indicate cell death by apoptosis induction.     

Two novel hydroperoxylated products of 20(S)-protopanaxadiol produced by Mucor racemosus and their cytotoxic activities against human prostate cancer cells

Microbial transformation of 20(S)-protopanaxadiol (1) by Mucor racemosus AS 3.205 yielded two novel hydroperoxylated metabolites and three known hydroxylated metabolites. The structures of the metabolites were identified as 26-hydroxyl-20(S)-protopanaxadiol (2), 23,24-en-25-hydroxyl-20(S)-protopanaxadiol (3), 25,26-en-24(R)-hydroperoxyl-20(S)-protopanaxadiol (4), 23,24-en-25-hydroperoxyl-20(S)-protopanaxadiol (5), and 25-hydroxyl-20(S)-protopanaxadiol (6). 4 and 5 are new compounds. Metabolites 2, 4, and 5 showed the more potent inhibitory effects against DU-145 and PC-3 cell lines than the substrate.     

Lipids isolated from the cultivated red alga Chondrus crispus inhibit nitric oxide production

A MeOH extract of cultivated Chondrus crispus showed dose-dependent nitric oxide (NO) inhibition of lipopolysaccharide-induced NO production in macrophage RAW264.7 cells. NO inhibition-guided fractionation of the extract led to identification of eicosapentaenoic acid (EPA, 1), arachidonic acid (AA, 2), lutein (3), and eight galactolipids as active components. Based on spectral analysis, the isolated galactolipids were identified as (2S)-1,2-bis-O-eicosapentaenoyl-3-O-β-d-galactopyranosylglycerol (4), (2S)-1-O-eicosapentaenoyl-2-O-arachidonoyl-3-O-β-d-galactopyranosylglycerol (5), (2S)-1-O-(6Z,9Z,12Z,15Z-octadecatetranoyl)-2-O-palmitoyl-3-O-β-d-galactopyranosylglycerol (6), (2S)-1-O-eicosapentaenoyl-2-O-palmitoyl-3-O-β-d-galactopyranosylglycerol (7), (2S)-1,2-bis-O-arachidonoyl-3-O-β-d-galactopyranosylglycerol (8), (2S)-1-O-arachidonoyl-2-O-palmitoyl-3-O-β-d-galactopyranosylglycerol (9), (2S)-1-O-eicosapentaenoyl-2-O-palmitoyl-3-O-(β-d-galactopyranosyl-6-1α-d-galactopyranosyl)-glycerol (10), and (2S)-1-O-arachidonoyl-2-O-palmitoyl-3-O-(β-d-galactopyranosyl-6-1α-d-galactopyranosyl)-glycerol (11). All the isolated compounds showed significant NO inhibitory activity. This is the first report of the isolation and identification of individual galactolipids from C. crispus. Moreover, (2S)-1,2-bis-O-arachidonoyl ?3-O-β-d-galactopyranosylglycerol (8) is a novel compound.     

Anti-microfouling properties of compounds isolated from several Mediterranean Dictyota spp.

Brown algae of the genus Dictyota are widespread around the world and are common along the coasts of the Mediterranean Sea. These marine organisms keep their surface relatively free from biofouling and are known for their ability to produce a wide array of bioactive compounds, mostly diterpenes, whose ecological functions are not clearly defined. In this study, an evaluation of the chemodiversity of the Dictyota genus was conducted on three samples, harvested on both NW and SW Mediterranean coasts (France and Algeria, respectively). Ten compounds were purified from the organic extracts of these samples; their chemical structures were elucidated by 1D and 2D NMR spectroscopy and were compared with literature data. Among them, three new diterpenes [one dolabellane (1), one xenicane (2), and one prenylated guaiane (3)] were characterized together with five previously described compounds [3,4-epoxy-14-oxo-7,18-dolabelladiene (4), acetoxycrenulide (5), dictyol E (6), 10,18-dihydroxydolabella-2,7-diene (7), and 10-acetoxy-18-hydroxydolabella-2,7-diene (8)]. In addition, the occurrence of two known glycerol derivatives [1-Ο-octadecenoylglycerol (9) and sn-3-Ο-(geranylgeranyl)glycerol (10)] was also determined. Some of the isolated compounds (4–6 and 8–10) were screened for their potential to prevent the adhesion of three bacterial strains isolated from marine biofilms in comparison with four commercial antifoulants (TBTO, Zineb, ZnPT, and CuPT): those bearing a glycerol moiety (compounds 9 and 10) exhibited the strongest anti-adhesion effects, whatever the strain, and with a moderate toxicity. Thus, these chemical structures should be further explored for both their putative involvement in keeping the algal surface free of biofouling and the development of effective and environmentally benign antifoulants.     

Protonation,alkylation, addition and redox reactions of 16, 17 and 18 valence electron [Mo(L)(NO)('S4')] complexes [L = SPh,PMe3, NO; 'S4'2– = 1,2-Bis-(2-mercaptophenylthio)ethane(2-)]

In the quest for complexes modelling functional characteristics of metal sulfur oxidoreductases, a series of molybdenum nitrosyl complexes with sulfur-dominated coordination sphere was synthesized. Treatment of the 16, 17 and 18 valence electron (VE) complexes [Mo(L)(NO)('S₄')] (1–3) [L?=?SPh (1), PMe₃ (2), NO (3), 'S₄'^2–?=?1,2-bis-(2-mercaptophenylthio) ethane(2-)] with the Brönsted acid HBF₄ resulted in formation of different types of products. 1 and 3 were reversibly protonated at one thiolate atom of the 'S₄'^2– ligand;2, however, yielded the phosphonium salt [HPMe₃]BF₄ and the dinuclear [Mo(NO)('S₄')]₂. Alkylation of 1, 2 and 3 by Me₃OBF₄ or Et₃OBF₄ uniformly resulted in high yields of [Mo(L)(NO)(R-'S₄')]BF₄ complexes [L?=?SPh: R?=?Me (5), Et (6); L?=?PMe₃: R?=?Me (7); L?=?NO: R?=?Me (8), Et (9)] in which one thiolate atom of the 'S₄'^2– ligand had become alkylated; the NMR spectra of 5, 6, 8 and 9 indicated that only one out of four theoretically possible diastereoisomers had formed. 5 and 6 were characterized also by single-crystal X-ray structure analyses. A comparison of ν(NO) bands and redox potentials (cyclic voltammetry) of parent complexes and alkylated derivatives showed that alkylation leads to a decrease in electron density at the molybdenum center and to a positive shift in redox potentials. The 16 VE complex 1 could be reduced, also chemically, to give the corresponding 17 VE anion [1]^–, and inserted elemental sulfur into the Mo-SPh bond, forming the 18 VE phenylperthio complex [Mo(η²–SSPh)(NO)('S₄')] (11) which, upon reaction with PPh₃, gave SPPh₃ and regenerated the parent complex 1. These results are discussed with regard to the sequence of proton and electron transfer steps occurring in substrate conversions catalyzed by metal sulfur oxidoreductases.     

Mono- and digalactosyldiacylglycerols: potent nitric oxide inhibitors from the marine microalga Nannochloropsis granulata

Chemical investigation of a marine microalga, Nannochloropsis granulata, led to the isolation of four digalactosyldiacylglycerols namely, (2S)-1-O-eicosapentaenoyl-2-O-palmitoyl-3-O-(β-d-galactopyranosyl-6-1α-d-galactopyranosyl)-glycerol (1), (2S)-1-O-eicosapentaenoyl-2-O-palmitoleoyl-3-O-(β-d-galactopyranosyl-6-1α-d-galactopyranosyl)-glycerol (2), (2S)-1-O-eicosapentaenoyl-2-O-myristoyl-3-O-(β-d-galactopyranosyl-6-1α-d-galactopyranosyl)-glycerol (3), and (2S)-1,2-bis-O-eicosapentaenoyl-3-O-(β-d-galactopyranosyl-6-1α-d-galactopyranosyl)-glycerol (4), together with their monogalactosyl analogs (5–8). Among the isolated galactolipids 2 and 3 were new natural products. Complete stereochemistry of 1, 4, 5, 7, and 8 was determined for the first time by both spectroscopic techniques and classical degradation methods. Both mono- and digalactosyldiacylglycerols isolated from N. granulata possessed strong nitric oxide (NO) inhibitory activity against lipopolysaccharide-induced NO production in RAW264.7 macrophage cells through downregulation of inducible nitric oxide synthase expression indicating the possible use as anti-inflammatory agents.     

Isolation and characterization of rat intestinal bacteria involved in biotransformation of (−)-epigallocatechin

Two intestinal bacterial strains MT4s-5 and MT42 involved in the degradation of (?)-epigallocatechin (EGC) were isolated from rat feces. Strain MT4s-5 was tentatively identified as Adlercreutzia equolifaciens. This strain converted EGC into not only 1-(3, 4, 5-trihydroxyphenyl)-3-(2, 4, 6-trihydroxyphenyl)propan-2-ol (1), but also 1-(3, 5-dihydroxyphenyl)-3-(2, 4, 6-trihydroxyphenyl)propan-2-ol (2), and 4′-dehydroxylated EGC (7). Type strain (JCM 9979) of Eggerthella lenta was also found to convert EGC into 1. Strain MT42 was identified as Flavonifractor plautii and converted 1 into 4-hydroxy-5-(3, 4, 5-trihydroxyphenyl)valeric acid (3) and 5-(3, 4, 5-trihydroxyphenyl)-γ-valerolactone (4) simultaneously. Strain MT42 also converted 2 into 4-hydroxy-5-(3, 5-dihydroxyphenyl)valeric acid (5), and 5-(3, 5-dihydroxyphenyl)-γ-valerolactone (6). Furthermore, F. plautii strains ATCC 29863 and ATCC 49531 were found to catalyze the same reactions as strain MT42. Interestingly, formation of 2 from EGC by strain MT4s-5 occurred rapidly in the presence of hydrogen supplied by syntrophic bacteria. Strain JCM 9979 also formed 2 in the presence of the hydrogen or formate. Strain MT4s-5 converted 1, 3, and 4 to 2, 5, and 6, respectively, and the conversion was stimulated by hydrogen, whereas strain JCM 9979 could catalyze the conversion only in the presence of hydrogen or formate. On the basis of the above results together with previous reports, the principal metabolic pathway of EGC and EGCg by catechin-degrading bacteria in gut tract is proposed.     

Novel 1,3,2-diazabora-[3]ferrocenophanes and a 1,4,2,3-diazadibora-[4]ferrocenophane

N,N′-Dilithiated 1,1′-bis(trimethylsilylamino)ferrocene (2) reacts with boron halide adducts (HBBr₂-SMe₂; BF₃-OEt₂ and BBr₃-SMe₂), boron halides (BCl₃, BBr₃, BCl₂(OPh) and BCl₂(Ph)) and 1,1-bis(dimethylamino)dichlorodiborane(4) to give the corresponding 1,3-bis(trimethylsilyl)-1,3,2-diazabora-[3]ferrocenophanes (3)-(8) and the 2,3-bis(dimethylamino)-1,4-bis(trimethylsilyl)-1,4,2,3-diazadibora-[4]ferrocenophane (9). All new complexes were characterised by multinuclear magnetic resonance spectroscopy in solution, and the solid-state molecular structures of the hydride (3), fluoride, chloride (4, 5), and of the phenoxy and phenyl derivatives (7, 8) were determined by X-ray analysis.     

Effect of selected dimethylaminochalcones on some mitochondrial activities

Chalcones and their synthetic cyclic analogues have been shown to possess a full scale of biological activities in a variety of experimental systems. They were assessed to be mostly effective in defense against free radicals in the organism, but several compounds exhibited cytotoxic pro-oxidant activities. The respiratory response and antioxidant status in mitochondria were investigated upon addition of 4′-dimethylaminochalcone (1a) and its cyclic analogues, (E)-2-(4′-((CH₃)₂?N)-benzylidene)-1-indanone (1b), -1-tetralone (1c), and -1-benzosuberone (1d). Selected structures were able to change the respiratory response of mitochondria and showed an ability to modify mitochondrial metabolic and redox efficiency, though they did not indicate redox reactivity towards glutathione in adduct-free incubations. The results of the study indicate that -chalcone and -tetralone derivatives cause suppression of reactive oxygen species affecting mitochondrial respiration by mild uncoupling. In addition, (E)-2-(4′-((CH₃)₂?N)-indanone (1b), and to a greater extent, -benzosuberone (1d), showed pro-oxidant effects, which partially explain their cytotoxicity.     

Cytotoxic metabolites from the cultures of endophytic fungi from Panax ginseng

Two strains of endophytic fungi, Penicillium melinii Yuan-25 and Penicillium janthinellum Yuan-27, with strong anti-Pyricularia oryzae activity, were obtained from the roots of Panax ginseng. Based on bioactivity-oriented isolation, a new benzaldehyde derivative, ginsenocin (1), together with six known compounds, methyl 2,4-dihydroxy-3,5,6-trimethylbenzoate (2), 3,4,5-trimethyl-1,2-benzenediol (3), penicillic acid (4), mannitol (5), ergosterol (6), and ergosterol peroxide (7), were separated from the EtOAc extract of Yuan-25 culture, while brefeldin A (8) was isolated as the major constituent from the EtOAc extract of Yuan-27 culture. The chemical structures were determined based on spectroscopic methods. All the isolated compounds 1–8 were evaluated for their cytotoxicity against six human cancer cell lines. Brefeldin A (8) was the most cytotoxic constituent against all the tested cell lines with IC₅₀ values <0.12 μg/ml, while ginsenocin (1) and penicillic acid (4) also exhibited potent cytotoxicity with IC₅₀ values ranging from 0.49 to 7.46 μg/ml. Our results suggest that endophytic fungi isolated from P. ginseng are a promising natural source of potential anticancer agents.     

Synthesis and Reactions of Some 2-Aminobenzothiazoles

N-(2-Benzothiazolyl)- and N-(6-methoxy-2-benzothiazolyl)cyanoacetamides 4, 5 resulted in the reaction of 2-aminobenzothiazole 1 or its 6-methoxy derivative 2 with 1-cyanoacetyl-3,5-dimethylpyrazole 3. Both cyanoacetylamides 4 and 5 have been transformed into the corresponding 2-oxo-2H-pyrimido[2,1-b]-benzothiazole-3-carbonitrile 8 and its 8-methoxy derivative 9 by reaction with triethyl orthoformate, followed by cyclization.     

Computational investigations on the electronic and structural properties of the unsaturated silylenoid HP=SiLiF

The structures of unsaturated silylenoid HP=SiLiF were studied by density functional theory at the B3LYP/6-311+G(d,P) level. Four equilibrium structures, the three-membered ring (1), the four-membered ring (2), the “classical” silane (3), and the linear (4) structures, were located. Their energies are in the order of 4?>?3?>?1?>?2. To exploit the stability of HP=SiLiF, the insertions reaction of 2 and HP=Si into C-Cl have been investigated, respectively. The results show that the insertion of HP=Si is more favorable. To compare with the saturated silylenoid, the insertion reaction of H₂SiLiF was also investigated. The calculations indicate that the insertion of HP=SiLiF (2) is more favorable. The unsaturated siylenoid HP=SiLiF has similar reaction characters to saturated silylenoid H₂SiLiF and silylene HP=Si.     

Synthesis of modified fragments of fibrinogen and their effect on the activity of proteolytic enzymes

New analogues of the Gly-Pro-Arg and Arg-Gly-Asp fragments of fibrinogen were synthesized: Gly-Pro-Arg-Pro (I), Gly-Pro-Arg-Pro-Met-OMe (II), Gly-Pro-Arg-Pro-Phe (III), Gly-Pro-Arg-Pro-Asp (IV), Gly-Pro-Arg-Pro-Glu (V), and Arg-Asn-Trp-Asp (VI). Their effect on the activity of proteases of various types was studied with the method of lysis of fibrin plates. All the peptides were found to inhibit plasmin activity (by 60–85%) and the γ-subunit of nerve growth factor (by 55–93%). Tetrapeptide (VI) proved to be an effective inhibitor of tissue activator of plasminogen and the γ-subunit of nerve growth factor (by 96 and 93%, respectively). The peptides exerted practically no effect on the activity of urokinase and moderately inhibited the activity of streptokinase [(III), IV), and (VI)], papain [(I), (II), IV), and (VI)], subtilisin [(V) and (VI)], α-chymotrypsin [(III), (V), and VI)], and Bacillus subtilis metalloprotease (VI). They inhibit trypsin [except for (I) and (III)] when applied on fibrin plates at a concentration of 1 × 10^?2 M, while, at the concentration of 1 × 10^?3 M, (I) and (II) induced an increase in proteolytic activity by 35 and 47%, respectively.     

Synthesis of 1,6-Diaryl-5,7-dioxo(dithio)imidazo[1,2-a] [1,3,5]triazines. A Novel Pathway for Imidazo[1,2-a] [1,3,5]triazine Systems Obtained via 1-(Imidazolin-2-yl)urea and Thiourea Derivatives

Novel 1,6-diaryl-5,7(1H)dioxo(dithio)-2,3-dihydroimidazo[1,2-a][1, 3, 5]triazines 8, and 9 were synthesized by cyclization of the respective 1-(imidazolin-2-yl)ureas 4 or thioureas 6 with phosgene or thiophosgene in the presence of bases. 1-Aryl-2-aminoimidazolines 1 reacting with arylisocyanates 2 or arylisothiocyanates 3 form a mixture of isomeric imidazolin-2-yl 4 and 6 and imidazolin-3-yl 5 and 7 urea or thiourea derivatives. Isomers 4 and 6 can be easily separated and used for the cyclization reaction. The structures of the main intermediates and the final target compounds were confirmed by ¹H-NMR spectral analysis. Discussion of the possible course of the reactions is also presented.     

Electron correlation effects and density analysis of the first-order hyperpolarizability of neutral guanine tautomers

Dipole moments (μ), charge distributions, and static electronic first-order hyperpolarizabilities (β _μ ) of the two lowest-energy keto tautomers of guanine (7H and 9H) were determined in the gas phase using Hartree–Fock, Møller–Plesset perturbation theory (MP2 and MP4), and DFT (PBE1PBE, B97-1, B3LYP, CAM-B3LYP) methods with Dunning’s correlation-consistent aug-cc-pVDZ and d-aug-cc-pVDZ basis sets. The most stable isomer 7H exhibits a μ value smaller than that of the 9H form by a factor of ca. 3.5. The β _μ value of the 9H tautomer is strongly dependent on the computational method employed, as it dramatically influences the β _μ (9H)/β _μ (7H) ratio, which at the highest correlated MP4/aug-cc-pVDZ level is predicted to be ca. 5. The Coulomb-attenuating hybrid exchange-correlation CAM-B3LYP method is superior to the conventional PBE1PBE, B3LYP, and B97-1 functionals in predicting the β _μ values. Differences between the largest diagonal hyperpolarizability components were clarified through hyperpolarizability density analyses. Dipole moment and first-order hyperpolarizability are molecular properties that are potentially useful for distinguishing the 7H from the 9H tautomer.

New diacylglyceryltrimethylhomoserines from the marine microalga Nannochloropsis granulata and their nitric oxide inhibitory activity

Chemical investigation of polar lipids from the marine eustigmatophyte microalga Nannochloropsis granulata led to the isolation of six betaine lipid diacylglyceryltrimethylhomoserine (DGTS), namely, (2S)-1,2-bis-O-eicosapentaenoylglyceryl-3-O-4′-(N,N,N-trimethyl)-homoserine (1), (2S)-1-O-eicosapentaenoyl-2-O-arachidonoylglyceryl-3-O-4′-(N,N,N-trimethyl)-homoserine (2), (2S)-1-O-eicosapentaenoyl-2-O-myristoylglyceryl-3-O-4′-(N,N,N-trimethyl)-homoserine (3), (2S)-1-O-eicosapentaenoyl-2-O-palmitoylglyceryl-3-O-4′-(N,N,N-trimethyl)-homoserine (4), (2S)-1-O-eicosapentaenoyl-2-O-palmitoleoylglyceryl-3-O-4′-(N,N,N-trimethyl)-homoserine (5), and (2S)-1-O-eicosapentaenoyl-2-O-linoleoylglyceryl-3-O-4′-(N,N,N-trimethyl)-homoserine (6). Structures of the isolated DGTSs were elucidated based on both spectroscopic technique and degradation methods. This is the first report of isolation of 1 in pure state, and 2–6 are all new compounds. The isolated betaine lipids showed dose-dependent nitric oxide (NO) inhibitory activity against lipopolysaccharide-induced nitric oxide production in RAW264.7 macrophage cells. Further study suggested that these betaine lipids (1–6) inhibit NO production in RAW264.7 macrophage cells through downregulation of inducible nitric oxide synthase expression, indicating the possible use as an anti-inflammatory agent. This is the first report of DGTS with anti-inflammatory activity.     

Novel Macrocyclic Monoterpene Glycosides from Bioactive Extract of Parkinsonia aculeata L

Five novel macrocyclic monoterpene O-glycosides, parkinsenes A–E (1–5), and eleven known phenolic metabolites including three 3-O-glycosylflavonols (6–8), five C-glycosylflavones (9–13), p-hydroxybenzoic acid (14), esculetin (15), and diosmetin (16) were isolated from the leaves and small twigs of Parkinsonia aculeata L. (Fabaceae). Their structures were established by chemical and spectroscopic analyses (UV, ESI–MS, and 1D/2D NMR). The investigated 80 % aqueous methanol extract (AME) showed significant analgesic, antipyretic, anti-inflammatory, hepatoprotective, hypoglycemic, hypocholesterolemic, and antioxidant activities in a dose-dependent manner using two different doses 250 and 500 mg/kg b. wt.
