Large-Scale Analysis of Pollen Viability and Oxidative Level Using H2DCFDA-Staining Coupled with Flow Cytometry was written by Rutley, Nicholas;Miller, Gad. And the article was included in Methods in Molecular Biology (New York, NY, United States) in 2020.Synthetic Route of C20H10Cl2O5 This article mentions the following:

Determining pollen viability and other physiol. parameters is of critical importance for evaluating the reproductive capacity of plants, both for fundamental and applied sciences. Flow cytometry is a powerful high-performance high-throughput tool for analyzing large populations of cells that has been in restricted use in plant cell research and in pollen-related studies, it has been minimized mostly for determination of DNA content. Recently, we developed a flow cytometry-based approach for robust and rapid evaluation of pollen viability that utilizes the reactive oxygen species (ROS) fluorescent reporter dye H2DCFDA (Luria et al., Plant J 98(5):942-952, 2019). This new approach revealed that pollen from Arabidopsis thaliana and Solanum lycopersicum naturally distribute into two subpopulations with different ROS levels. This method can be employed for a myriad of pollen-related studies, primarily in response to stimuli such as biotic or abiotic stress. In this chapter, we describe the protocol for H2DCFDA staining coupled with flow cytometry anal. providing specific guidelines. These guidelines are broadly applicable to many other types of cellular reporters to further develop this novel approach in the field of pollen biol. In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Synthetic Route of C20H10Cl2O5).

Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.Synthetic Route of C20H10Cl2O5

Background: Vigabatrin is a variant of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). It reduces seizure activities by inhibiting irreversibly GABA transaminase and increasing GABA concentrations Objective: This study presents simple, sensitive, extraction-free, and cost-efficient estimation of vigabatrin using a spectrophotometric method in pharmaceutical formulation. Method: The method relies on the development of water-soluble, blue-violet colored complexes of vigabatrin and ninhydrin in a phosphate buffer of pH 7.4 with λmax at 565 nm. Linearity, accuracy, precision, and specificity were performed as validation parameters for this method. Results: Assessment of different anal. factors was carried out, and statistical anal. was performed to validate the results. The findings showed a linear progression in absorbance when the concentration of vigabatrin was increased. The correlation coefficient value (r2) of 0.9981 was observed The operations followed the Beer’s law in the span of 40-200 μgmL-1 with a molar absorptivity of 5.16×103 Lmol-1cm-1. Recovery values in the marketed formulation of the assay method indicated no interference from the common additives and excipients. The limits of detection and quantification were found to be 6.0 and 40 μgmL-1, resp.

A highly sensitive, simple and selective spectrofluorimetric method has been developed and validated for determination of doxazosin mesylate in pure form, pharmaceutical formulations and human plasma. The method is based on the reaction between doxazosin mesylate and fluorescamine in Teorell buffer solution (pH 3) to give highly fluorescent derivative that can be measured at 489 nm using excitation wavelength of 385 nm. Different exptl. parameters affecting the reaction were carefully studied and optimized. The calibration plot was constructed over the concentration range of 16-400 ng mL^– 1 with quantitation limit of 14.3 ng mL^– 1. The developed procedure was validated according to ICH guidelines and the results were satisfactory. The proposed method has been successfully applied to the anal. of the cited drug in its pharmaceutical preparations as well as for content uniformity testing. The results showed excellent agreement with the reported method with respect to precision and accuracy.

Analysis of pesticide monocrotophos toxicity using Drosophila melanogaster model was written by Naveen, Kumar HN;Meghana;K Shettar, Arun;Thippeswamy, Tg;Niranjana, P..

Aim: Monocrotophos poisoning is a common medical emergency with high fatality in agricultural communities of Asia. Major cause of morbidity and mortality of poisoning is because it inhibits acetylcholinesterase and prolongs neuromuscular weakness. With this background present study was undertaken to analyze the toxicity and effect of Pesticide Monocrotophos on Drosophila melanogaster model. Materials and Methods: Oxidative stress is implicated in mitochondrial dysfunction associated with neurodegeneration in various diseases. Depletion of the cellular antioxidant glutathione (GSH) resulting in oxidative stress is considered as an early event in degeneration of neurons and mitochondrial complex I (CI) is believed to be the central player to the mitochondrial dysfunction. Results: The potential insults independently inhibit CI and other complexes of the electron transport chain, drop the proton motive force, and reduce ATP production, ultimately affecting the overall mitochondrial performance. Conclusion: Here we tested the effect of Monocrotophos in drosophila model and showed that monocrotophos generates reactive species which decreased reduced glutathione (GSH) and concurrently increased oxidized glutathione (GSSG) levels, which in turn led to inhibition of mitochondrial complex I and complex II activities results in motor dysfunction and death of Drosophilaflies.

A polemic in response to Hao et. al., Biomed. Pharmacother. 122 (2020), 109677 is reported. Hao et. al., stated that acetylshikonin induces apoptosis of human leukemia cell line K562 by inducing S phase cell cycle arrest, modulating ROS accumulation, depleting Bcr-Abl and blocking NF-&kappaB signaling. The comprehensive study by Hao and colleagues is on the effect of acetylshikonin on the K562 cell line including modulation of intracellular reactive oxygen species (ROS) accumulation. However, the authors like to point out an error in reagent nomenclature/citation in their paper. This is actually a recurring issue in literature and has the potential to affect other research results just as it undermined theirs, recently. For a recent pilot experiment on human erythrocytes, the authors needed to measured intracellular ROS generation in various hematol. disorders. Guided by several prior publications, including Hao et al., a 2′,7′-dichlorodihydrofluorescein diacetate (DCFH2-DA)-based flow cytometric experiment was designed. This is potentially confusing for future buyers who may land there following the SKU number wrongly quoted in the publications.
