Basic Research Journal of Microbiology, 2016 June, 3(2): 08-11. | Antimicrobial activity of 1,2-benzenedicarboxylic acid, butyldecyl ester isolated from the seeds and pods of Acacia nilotica Linn[Reference: WebLink] | The antimicrobial activity of 1,2-Benzenedicarboxylic acid, butyldecyl ester isolated from Acacia nilotica was determined using standard methods. METHODS AND RESULTS: The compound was isolated by directing the fractionation of ethyl acetate extract of the air dried seeds and pod with microbial sensitivity test. The results of the antibacterial screening showed that the ethyl acetate extract of Acacia nilotica Linn exhibited the highest activities against the test microbes with zones of inhibition diameter ranging from 27-32mm against Salmonela typhi, Escherichia coli, Streptococcus feacalis, Staphylococcus aureus, Candida krusei and Shigella dysentriae.
CONCLUSIONS:
The structure of the compound was identified from 13CNMR, 1HNMR, IR and GC-MS spectral data. The isolation, structural elucidation, NMR spectral assignment and bioactivities are reported. | International Journal of Pharma & Bio Sciences, 2015 , 6 (1) :1190-1195. | In-Silico Analysis of Streptomyces sp secondary metabolite 1,2-Benzenedicarboxylic acid, mono (2-ethylhexyl) Ester with ESBL proteins[Reference: WebLink] | The anti-ESBL activity of 1,2-Benzenedicarboxylic acid, mono (2-ethylhexyl) ester (DMEHE) extracted from marine Streptomyces sp strain VITSJK8 was further confirmed by in silico analysis.
METHODS AND RESULTS:
A total of 10 ESBL proteins was chosen for this study from the protein data bank (PDB) and were docked with the DMEHE. The resultant atomic contact energy (ACE) was compared with dockings of known antibiotic ertapenem, penicillin G, amoxicillin, rocephin and cefozopran. PatchDock online docking server was utilized for docking studies. LigPlot+ and PyMOL were used to evaluate the docking results obtained from PatchDock. The docking of DMEHE with ESBL proteins showed the ACE value range from -198.42 to 22.62, while docking of ertapenem showed the ACE value range from -217.67 to -71.8. DMEHE formed hydrogen bonds with AMPC, CTXM-9, TEM-1 and TEM-52 ESBL proteins. The interaction between DMEHE and ESBL protein complex was unstable and no covalent bond formation was observed, whereas ertapenem and ESBL complex was highly stable because of the covalent bond and hydrogen bond formation in the ligand-protein interaction. Similarly penicillin G, amoxicillin, rocephin and cefozopran also demonstrated higher stability with ESBL proteins compared to DMEHE.
CONCLUSIONS:
Based on this study, it could be concluded that bacterial proteins will not involve in lysis of DMEHE and therefore DMEHE would be an effective drug for treating the drug resistant ESBL pathogens. | Journal of Gansu Agricultural University, 2007, 42(5):43-48. | Identification of root exudation of Zea mays L. and allelopathy of 1,2-benzenedicarboxylic acid[Reference: WebLink] | Root exudation is one of the most important resources of allelochemical.
METHODS AND RESULTS:
In this study,the root exudation of Zea mays L.seedlings,which were cultivated in liquid,was extracted with C2Cl2 35 d ays after germination,and was identified by the way of gas chromatographymass spectrometry(GC-MS).At the same time,the biological characteristics of the typical exudation 1,2-Benzenedicarboxylic acid was tested through germination experiment.
CONCLUSIONS:
The results indicated that the component of the exudation mainly included hydrocarbon,benzene,thiazole,organic acid,ketone,amide,grease,mellow and phenol etc.The typical exudation 1,2-Benzenedicarboxylic acid as one kind of allelochemical showed stronger allelopathic effect on itself than on wheat and pigeonpea. |
