A Potential Role of Coumestrol in Soybean Leaf Senescence and Its Interaction With Phytohormones

Coumestrol is a natural organic compound synthesized in soy leaves and functions as a phytoalexin. The coumestrol levels in plants are reported to increase upon insect attack. This study investigates the correlation between coumestrol, senescence, and the effect of phytohormones on the coumestrol levels in soybean leaves. Our analysis involving high-performance liquid chromatography and 2-D gel electrophoresis indicated a significant difference in the biochemical composition of soybean leaves at various young and mature growth stages. Eight chemical compounds were specifically detected in young leaves (V1) only, whereas three different coumestans isotrifoliol, coumestrol, and phaseol were detected only in mature, yellow leaves of the R6 and R7 growth stage. MALDI-TOF-MS analysis was used to identify two proteins 3,9 -dihydroxypterocarpan 6A-monooxygenase (CYP93A1) and isoflavone reductase homolog 2 (IFR2) only in mature leaves, which are key components of the coumestrol biosynthetic pathway. This indicates that senescence in soybean is linked to the accumulation of coumestrol. Following the external application of coumestrol, the detached V1-stage young leaves turned yellow and showed an interesting development of roots at the base of the midrib. Additionally, the application of phytohormones, including SA, methyl jasmonate (MeJA), and ethephon alone and in various combinations induced yellowing within 5 days of the application with a concomitant significant increase in endogenous coumestrol accumulation. This was also accompanied by a significant increase in the expression of genes CYP81E28 (Gm08G089500), CYP81E22 (Gm16G149300), GmIFS1, and GmIFS2. These results indicate that various coumestans, especially coumestrol, accumulate during leaf maturity, or senescence in soybean.

Modulation of Intracellular ROS and Senescence-Associated Phenotypes of Xenopus Oocytes and Eggs by Selective Antioxidants

Aging of oocytes and eggs diminishes their reproductive and developmental potential. It has been demonstrated previously that reactive oxygen species (ROS) contribute to accelerated aging of various cells. In the present study, we measured intracellular levels of ROS and investigated effects of several selective antioxidants (AOXs) on the viability and functional activity of aging oocytes and eggs of the African clawed frog Xenopus laevis. The fluorescent cell-permeable dye DCFDA, which is widely employed for ROS detection in cultured mammalian cells, was used to monitor ROS levels in the fresh and bench-aged oocytes and eggs by an optimized protocol. It was found that intracellular ROS contents were increased in frog oocytes and eggs aged for 48 h. It was further demonstrated using selective cell-permeable AOXs targeting different ROS-generating mechanisms, that the major source of ROS in Xenopus oocytes and eggs is the plasma membrane NADPH oxidase, and that mitochondrial generation contributes to the intracellular ROS content to a lesser extent. Targeted inhibition of NADPH oxidase with a natural organic compound apocynin reduced ROS levels significantly in Xenopus oocytes and eggs, maintained their normal phenotype and supported their functional competence. To our knowledge this is the first report concerning beneficial effects of apocynin on the isolated gamete cells, such as oocytes and eggs.

Hydroxycoumarin Grafted with Hydrazine: Synthesis, Structure Elucidation and Assessment of Antioxidant and Antibacterial Characteristics

4-Hydroxycoumarin, as a natural organic compound, was structurally grafted onto a benzaldehyde by hydrazine. The chemical structure of grafted macromolecule was confirmed by FT-IR and NMR spectroscopy. The antibacterial activity of the synthesized grafted macromolecule against Staphyloccocus aureus, E. coli, Proteus vulgaris, Pseudomonas, and Klebsiella pneumoniae was assessed using a disc diffusion technique. The antioxidant activity of the grafted macromolecule was also highlighted using the superoxide-radical technique. The grafted macromolecule has high inhibition activity against all tested bacteria. The grafted macromolecule was a much more effective free radical scavenger than vitamin C.

Epigallocatechin-3-gallate yield in different temperature gradients in green tea (Camellia sinensis) brewing

ABSTRACTIntroductionEpigallocatechin-3-gallate (EGCG) is a chemical catechin, a natural organic compound found in green teas with strong antioxidative effects. EGCG degrades or epimerizes according to temperature, fluctuating its concentration in green tea (Camellia sinensis). This study is conducted to determine the specified correlation between EGCG and tea temperature, and to conclude with the optimal temperature for EGCG yield.MethodsEGCG concentrations in different solutions of green tea are analyzed using a high-performance liquid chromatography (HPLC), with a diode array detector (DAD). The solutions are created from green tea brewed in water from 20°C to 100°C at increments of 20°C and undergo an ultrasonic bath of 30 minutes before being analyzed.ResultsThere is a discernible difference between EGCG concentrations in all temperatures. At 20, 40, 60, 80 and 100°C, the concentrations are 6.18 μg/mL, 32.37 μg/mL, 57.36 μg/mL, 36.13 μg/mL, and 44.85 μg/mL, respectively. EGCG concentration maximizes at 60°C. The lowest EGCG concentration yield is at 20°C.ConclusionThe results of our experiments lead us to recommend hot brewing over cold brewing for green tea if one wishes to maximize the potential of the effects of EGCG due to its higher concentration.

Gold Nanoparticle-Conjugated Cinnamic Acid Exhibits Antiacanthamoebic and Antibacterial Properties

ABSTRACT trans-Cinnamic acid (CA) is a natural organic compound. Using amoebicidal assays, for the first time we showed that CA affected the viability of the protist pathogen Acanthamoeba castellanii. Conjugation with gold nanoparticles (AuNPs) enhanced the antiamoebic effects of CA. CA-coated AuNPs (CA-AuNPs) also exhibited significant excystation and encystation activity, compared to CA and AuNPs alone. Pretreatment of amoebae with CA-AuNPs inhibited A. castellanii-mediated host cell cytotoxicity. Moreover, CA-AuNPs exhibited potent effects against methicillin-resistant Staphylococcus aureus and neuropathogenic Escherichia coli K1 and protected host cells against bacteria-mediated host cell death.

Study of the biological effect of oligochitosan prepared by γ-CO-60 irradiation method on Spirulina platensis

Chitosan with initial molecular weight (Mw) about 193 kDa and the deacetylation degree of about 80% was irradiated by gamma rays from a Co-60 source in powder state for degradation. The results on Mw estimation by gel permeation chromatography method indicated that oligochitosan products with Mw from 3.7 to 28.9 kDa were successfully prepared by irradiation of chitosan samples at doses from 300 to 2000 kGy. The prepared oligochitosans were then supplemented into the cultivated media for investigation of the biological effect on the cyanobacteria (blue – green alga) namely Spilurina platensis. The obtained results indicated that all of radiation degraded chitosan samples showed a growth promotion effect on the enhancement of fresh and dried biomass S. platensis after 7 days supplementation. The oligochitosan product with Mw ~ 15,4 kDa obtained from the irradiation dose of 500 kGy displayed the best growth promotion effect for the tested alga and the optimum concentration for supplementation of this product was found at 100 ppm. In addition, The supplementation with 100 ppm of the oligochitosan product enhanced 49.5% the fresh biomass and 59.1% the dried biomass of the tested alga after 7 days cultivating. The addition of oligochitosan also increased the dried matter, protein, carbohydrate and lipid contents of the harvested alga product in 7.0, 23.3, 27.3 and 37.5%, respectively. It can be seen that the oligochitosan product prepared from natural organic compound by gamma Co-60 irradiation method promised to be potential used as a safe and highly effective growth promoter for alga to biomass production of S. platensis.

Antioxidant Properties of Resveratrol and its Protective Effects in Neurodegenerative Diseases

Summary Resveratrol is a natural organic compound, polyphenol, produced naturally by some plants in response to several harmful factors such as attack by pathogens, UV radiation, or increased oxidative stress. Many experiments suggest that it triggers mechanisms that counteract aging-related effects and plays a role in insulin resistance as well. It also possesses beneficial properties such as anti-cancer, anti-inflammatory, blood-sugar-lowering and cardiovascular effects. It is supposed to exhibit an interesting activity in neuroprotection - mainly through activation of sirtuins and counteraction in forming peptide aggregates. Still research is needed to evaluate exactly how resveratrol protects neurons, and to develop new, potential, therapeutic drugs
