Benzophenones from Hypericum carinatum
J Nat Prod 2005 May;68(5):784-6.PMID:15921431DOI:10.1021/np040149e.
Two new benzophenones were isolated from the leaves of Hypericum carinatum. Their structures were established on the basis of 2D NMR spectroscopic analyses and mass spectrometry as cariphenone A (6-benzoyl-5,7-dihydroxy-2,2,8-trimethyl-2H-chromene) (1) and cariphenone B (8-benzoyl-5,7-dihydroxy-2,2,6-trimethyl-2H-chromene) (2). Five known compounds, the phloroglucinol derivative uliginosin B (3), 1-Eicosanol, sitosterol, stigmasterol, and campesterol, were also characterized. Compounds 1-3 were evaluated for their total antioxidant capacity through a total radical-trapping parameter assay. Only compound 1 showed moderate antioxidant activity, exhibiting inhibition of chemiluminescence similar to that of quercetin at the same concentration.
Toxicity studies of nanofabricated palladium against filariasis and malaria vectors
Environ Sci Pollut Res Int 2018 Jan;25(1):324-332.PMID:29034429DOI:10.1007/s11356-017-0428-x.
The present study was carried out to establish the biofabrication of palladium nanoparticles (PdNPs) using the plant leaf extract of Tinospora cordifolia Miers and its toxicity studies on the larvae of filariasis vector, Culex quinquefasciatus Say and malaria vector, Anopheles subpictus Grassi. The biofabricated PdNPs were characterized by using UV-visible spectrum, FTIR, XRD, FESEM, EDX and HRTEM. HRTEM confirmed the PdNPs were slightly agglomerated and spherical in shape and the average size was 16 nm. Gas chromatography and mass spectrometry analysis result revealed that the major constituent present in the T. cordifolia leaf extract is 2,4-di-tert-butylphenol (31.79%) whereas the minor compounds are 1-hexadecanol (7.97%), 1-octadecanol (7.70%), 1-Eicosanol (6.85%), behenic alcohol (5.36%), 1-tetradecene (6.22%), cyclotetradecane (6.23%), 1-hexadecene (7.97%), 1-octadecene (7.70%), 1-eicosene (6.85%), and 1-docosene (5.36%). T. cordifolia leaf extract exhibited the larvicidal activity against the fourth instar larvae of C. quinquefasciatus and A. subpictus with the values of LC50 = 59.857 and 54.536 mg/L; LC90 = 113.445 and 108.940 mg/L, respectively. The highest toxicity was observed in the biofabricated PdNPs against the fourth instar larvae of C. quinquefasciatus and A. subpictus with the values of LC50 = 6.090 and 6.454 mg/L; LC90 = 13.689 and 13.849 mg/L, respectively. Concerning non-target effects, Poecilia reticulata were exposed to PdNPs for 24 h and did not exhibit any noticeable toxicity. Overall, our findings strongly suggest that PdNPs is a perfect ecological and inexpensive approach for the control of filariasis and malaria vectors.
Synthesis of Phosphoester Compounds Using Lactic Acid for Encapsulation of Paclitaxel
Anticancer Res 2018 Jun;38(6):3401-3406.PMID:29848689DOI:10.21873/anticanres.12607.
Background/aim: In the use of paclitaxel, side-effects caused by itself or solubilizing agents have become a major obstacle. In this study we aimed to synthesize biocompatible and degradable compounds for micelles to be used as carriers for paclitaxel. Materials and methods: Methoxypolyethylene glycol-lactate was obtained from methyl lactate and methoxypolyethylene glycol having a molecular weight of 350. Monoalkoxy phosphoryl chlorides were obtained from phosphoryl chloride and four kinds of linear alcohols. Then, four kinds of alkyl di(methoxypolyethylene glycol-lactate) phosphates were obtained from them. Results: The results of 1H NMR spectroscopy showed that alkyl di(methoxypolyethylene glycol-lactate) phosphates were successfully synthesized. When 1-dodecanol, 1-hexadecanol, 1-octadecanol, and 1-Eicosanol were used as side chains, the yields were 73.5±4.2, 69.1±3.6, 72.2±2.8, and 71.8±3.7%, respectively. The spectrum of 31P NMR suggested the existence of optical isomers. Conclusion: Four kinds of phosphoester compounds for micelle preparations were synthesized using lactic acid.
Chromatographic and spectroscopic determination of solvent-extracted Lantana camara leaf oil
J Int Med Res 2020 Oct;48(10):300060520962344.PMID:33100100DOI:10.1177/0300060520962344.
Objective: This study aimed to determine the chemical profile of Lantana camara leaf oil. Methods: The essential oil was extracted from dried leaf samples using the Soxhlet extraction method. The oil was separated from the solvent and the bioactive compounds were identified using gas chromatography-mass spectroscopy (GC-MS) and Fourier transform infrared spectroscopy (FTIR). The identified peaks in the mass spectrum were matched with the database of the US National Institute of Standards and Technology (NIST) library. Results: The FT-IR results indicated the presence of alcohols, carboxylic acids, phenols, alkanes, ketones, and primary amine compounds. GC-MS identified 43 compounds representing 95% of the total leaf essential oil components. Some of the major isolated compounds included a pyrrolizine; 1-dodecanol; 1,2-nonadecanediol; phytol; 1,3-dioxolane; 4-undecene, 9-methyl, (Z)-; 1-Eicosanol; and imidazole. Conclusions: The identified constituents of the extracted oil have established pharmacologic and insecticidal activities, and these compounds are also used in the drink, food, and cosmetic industries. This extract is highly valuable for the medical treatment of various ailments.
GC-MS analysis of organic fractions of Chrozophora tinctoria (L.) A.Juss. and their prokinetic propensity in animal models
Braz J Biol 2022 May 20;84:e260566.PMID:35613215DOI:10.1590/1519-6984.260566.
Chrozophora tinctoria (L.) A.Juss. is herbaceous, monecious annual plant used traditionally to cure gastrointestinal disorders. The present study was carried out to find the bioactive compounds by Gas Chromatography-Mass Spectrometry, the acetylcholinesterase inhibitory potential acute toxicity, and emetic activity present in the ethyl acetate fraction of Chrozophora tinctoria (EAFCT) and dichloromethane fraction of Chrozophora tinctoria (DCMFCT). The compounds detected in both fractions were mostly fatty acids, with about seven compounds in EAFCT and 10 in DCMFCT. These included pharmacologically active compounds such as imipramine, used to treat depression, or hexadecanoic acid methyl ester, an antioxidant, nematicide, pesticide, hypocholesterolemic, 9,12,15-Octadecatrienoic acid, ethyl ester, (Z,Z,Z)- is used as a cancer preventive, antiarthritic, antihistaminic, hepatoprotective, insectifuge, nematicide, Pentadecanoic acid, 14-methyl-, methyl ester have antifungal, antimicrobial and antioxidant activities, 10-Octadecanoic acid, methyl ester have the property to decrease blood cholesterol, Antioxidant and antimicrobial, 1-Eicosanol is used as an antibacterial, 1-Hexadecene has antibacterial, antioxidant, and antifungal activities. Both DCMFCT and EAFCT fractions inhibited acetylcholinesterase (AChE) activity with IC50 values of 10 µg and 130 µg, respectively. Both the fractions were found to be toxic in a dose-dependent manner, inducing emesis at 0.5g onward and lethargy and mortality from 3-5 g upwards. Both the fractions combined with distilled water showed highly emetic activity. The significant increase in the number of vomits was shown by EAFCT plus distilled water which are 7.50±1.29, 7.25±3.10, and 11.75±2.22 number of vomits at 1g, 2g, and 3g/kg concentration respectively, while DCMFCT plus distilled water showed 5.25±2.22, 7.50±2.52 and 10.25±2.22 number of vomits at 1g, 2, and 3g/kg correspondingly. The antiemetic standard drug metoclopramide has a higher impact against the emesis induced by both the fractions than dimenhydrinate. Metoclopramide decreases the number of vomits caused by EAFCT to 1.00±0.00, 2.00±0.00, 4.00±1.00 at 1g, 2, and 3g/kg sequentially, while dimenhydrinate decreases the number of vomits to 1.33±0.58, 2.33±1.15, 4.33±0.58 at 1g, 2, and 3g respectively. In the same way, Metochloprimide decreases the number of emesis caused by DcmCt from 5.25±2.22, 7.50±2.52, 10.25±2.22 to 1.33±0.58, 2.33±1.1, 4.33±0.58 at 1g, 2, and 3g/kg concentrations. The present study is the first documented report that scientifically validates the folkloric use of Chrozophora tinctoria as an emetic agent.
