Simultaneous determination of 2-Naphthoxyacetic acid and indole-3-acetic acid by first derivation synchronous fluorescence spectroscopy
Spectrochim Acta A Mol Biomol Spectrosc 2013 Jul;111:230-6.PMID:23651742DOI:10.1016/j.saa.2013.04.021.
A simple, rapid, sensitive and selective method for simultaneously determining 2-Naphthoxyacetic acid (BNOA) and Indole-3-Acetic Acid (IAA) in mixtures has been developed using derivation synchronous fluorescence spectroscopy based on their synchronous fluorescence. The synchronous fluorescence spectra were obtained with Δλ=100 nm in a pH 8.5 NaH2PO4-NaOH buffer solution, and the detected wavelengths of quantitative analysis were set at 239 nm for BNOA and 293 nm for IAA respectively. The over lapped fluorescence spectra were well separated by the synchronous derivative method. Under optimized conditions, the limits of detection (LOD) were 0.003 μg/mL for BNOA and 0.012 μg/mL for IAA. This method is simple and expeditious, and it has been successfully applied to the determination of 2-Naphthoxyacetic acid and indole-3-acetic acid in fruit juice samples with satisfactory results. The samples were only filtrated through a 0.45 μm membrane filter, which was free from the tedious separation procedures. The obtaining recoveries were in the range of 83.88-87.43% for BNOA and 80.76-86.68% for IAA, and the relative standard deviations were all less than 5.0%. Statistical comparison of the results with high performance liquid chromatography Mass Spectrometry (HPLC-MS) method revealed good agreement and proved that there were no significant difference in the accuracy and precision between these two methods.
Simultaneous determination of plant growth regulators 1-naphthylacetic acid and 2-Naphthoxyacetic acid in fruit and vegetable samples by room temperature phosphorescence
Phytochem Anal 2012 May-Jun;23(3):214-21.PMID:21805518DOI:10.1002/pca.1345.
Introduction: 1-Naphthylacetic and 2-naphthoxyacetic acids belong to the synthetic branch of auxins. Auxins have attracted considerable interest as a subject of study by virtue of their biological and physiological significance. Their broad use as plant growth regulators has raised the need for simple, rapid, sensitive and selective analytical methods for their determination in real samples. Objective: The primary aim of this work was to develop an analytical method for the simultaneous determination of 1-naphthylacetic acid and 2-Naphthoxyacetic acid in commercial technical formulations, tomato and various fruit types (apple, strawberry, orange and plum) by room temperature phosphorescence. Methodology: Filtrated solutions of aqueous slurries from ecological fruit and tomato samples are acidified and then extracted with dichloromethane. Once the solvent is evaporated, the dried residue is dissolved in sodium dodecyl sulphate (a micellar agent), and supplied with thallium (I) nitrate as an external heavy atom source and sodium sulphite as deoxygenation agent to enhance the ensuing phosphorescence. Results: The broad-band overlapping spectra for the two analytes were resolved by first- and second-derivative phosphorescence spectrometry. Zero-crossing measurements at 488.5 nm in the first-derivative spectrum and 469.5 nm in the second derivative spectrum exhibited a linear dependence on the 2-Naphthoxyacetic acid and 1-naphthylacetic acid concentration, respectively. The detection limits as determined in accordance with the error propagation theory were 11.5 ng/mL for 1-naphthylacetic acid and 15.6 ng/mL for 2-Naphthoxyacetic acid. Conclusion: The proposed method affords the determination of 1-naphthylacetic acid and 2-Naphthoxyacetic acid in real samples with near-quantitative recoveries from agricultural products.
2-Amino-2-thiazoline and its 1:1 organic salt with 2-Naphthoxyacetic acid
Acta Crystallogr C 2004 Sep;60(Pt 9):o677-9.PMID:15345854DOI:10.1107/S0108270104015604.
The crystal structures of 2-amino-2-thiazoline, C3H6N2S, and 2-amino-2-thiazolinium 2-naphthoxyacetate, C3H7N2S+.C12H9O3-, are reported. The structure of 2-amino-2-thiazoline consists of two unique molecules that construct a convoluted hydrogen-bonded ribbon involving R(2)2(8) graph-set association via both N-H...N and N-H...S interactions. The organic salt structure consists of the two molecules associated via an R(2)2(8) graph-set dimer through N-H...O interactions, with the hydrogen-bonding network propagated via additional N-H...O three-centre interactions from the second 2-amine H atom.
1,3,4-Thiadiazolo (3,2-Α) Pyrimidine-6-Carbonitrile Scaffold as PARP1 Inhibitors
Anticancer Agents Med Chem 2021;21(15):2050-2065.PMID:33327923DOI:10.2174/1871520621666201216095018.
Background: 1,3,4-thiadiazolo pyrimidine is a lead molecule that is versatile for a wide variety of biological activities and in continuation of our interest in establishing some novel heterocyclic compounds for antitumor activity. Objective: The objective of the study was to synthesize a series of 5-amino-7-(substituted aldehyde)-2[(naphthalene- 2-yloxy)methyl] -[1,3,4]thiadiazolo-[3,2-α]-pyrimidine-6- carbonitrile derivatives and evaluate their possible in vitro and in vivo anticancer activity. Methods: Herein, we report the synthetic scheme, which was followed for the preparation of a series of title compounds B1- B9 outlined in scheme 1. The intermediate 5-[(naphthalen-2- yloxy)methyl]-1,3,4-thiadiazolo- 2-amine was prepared by heating 2-Naphthoxyacetic acid and thiosemicarbazide in the presence of phosphoryl chloride at a temperature of 65-75°C. The obtained compound reacted with malononitrile and an appropriate amount of aromatic and heteroaromatic aldehydes in refluxing ethanol yielded 5-amino-7-(substituted aldehyde)-2[(naphthalene-2-yloxy)methyl] -[1,3,4]thiadiazolo-[3,2-α]-pyrimidine-6- carbonitrile derivatives (B1 - B9). The purity of the synthesized compounds was ensured by various spectral analyses. Results: In in silico molecular docking studies, compounds B3 and B9 show binding affinity like known PARP1 inhibitor olaparib. The cellular evaluation indicates that the anticancer profile of compounds B1, B3, and B9 is significant when compared to the standard drug (olaparib) against MDA-MB-232 cell line and compounds B3, B6, and B7 are the most active against MCF-7 cell lines. The most active compound B3 was subjected to acute oral toxicity studies by OECD 423 guidelines and in vivo anti-cancer studies were carried out using DMBA induced model. Conclusion: The in silico docking study of the newly synthesized compounds was performed; the results showed good binding mode in the active site of PARP1 enzyme. In silico ADME properties of synthesized compounds were also studied and showed good drug-like properties.
Modified QuEChERS method for 24 plant growth regulators in grapes using LC-MS/MS
J Food Drug Anal 2018 Apr;26(2):637-648.PMID:29567233DOI:10.1016/j.jfda.2017.08.001.
A multiresidue analytical method was developed for grapes for the following 24 plant growth regulators: 1-naphthylacetamide, 2,3,5-triiodobenzoic acid, 2,4,5-T, 2-Naphthoxyacetic acid, 3-indolylacetic acid, 4-(3-indolyl)-butyric acid, 4-chlorophenoxyacetic acid, 4-nitrophenol, 6-benzylaminopurine, N6-isopentenyladenine, butralin, chlormequat chloride, chlorphonim-Cl, cloprop, forchlorfenuron, gibberellic acid 3, gibberellic acid 4, gibberellic acid 7, inabenfide, mepiquat chloride, paclobutrazol, prohydrojasmon, thidiazuron and uniconizole-P. The compounds were extracted from grape samples using an extraction method modified from the Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method. Liquid chromatography - tandem mass spectrometry was used for the detection and quantification of the compounds. Validation of the method was performed by using recovery studies at both intra-day and inter-day intervals, as well as by evaluation of the matrix effect, limit of quantification, trueness and precision. We used matrix-matched calibrations for the quantification of the compounds, which all resulted in determination coefficients (r2) higher than 0.995. The limit of quantification ranged from 0.1 to 5 ng/mL. Recovery studies using three spiking concentrations at varying levels showed recoveries of 70.2-112.6% and 67.5-101.8% at intra-day and inter-day intervals, respectively. Relative standard deviations were below 20% for the recovery studies. The extraction method were further validated by performing recovery study and matrix effect test in six different grape varieties from Taiwan and the United States and all resulted in comparable results. Application of the established method to 50 grape samples, resulted in the detection of chlormequat chloride and forchlorfenuron residues in the tested grapes. The results of the method validation and real sample analysis shows the extraction method is therefore suitable for routine monitoring of residue in grapes.
