Hydrogen sulfide mitigates cadmium induced toxicity in Brassica rapa by modulating physiochemical attributes, osmolyte metabolism and antioxidative machinery

Hydrogen sulfide (H2S) is helpful for maintaining plant growth under abiotic stresses. The current study elucidated the physiological and biochemical strategies by which sodium hydrosulfide (NaHS), a donor of H2S, alleviated cadmium (Cd) toxicity in Brassica rapa. B. rapa plants growing under 50 mgkg(-1) Cd stress showed reduced leaf relative water contents (LRWC), photosynthetic pigments, total soluble proteins, minerals uptake, antioxidants and growth. Furthermore, enhanced accumulation of Cd contents caused augmentation in levels of electrolyte leakage (EL) and methylglyoxal (MG). Nevertheless, improved physiochemical parameters in B. rapa seedlings obtained from seeds primed with 1.5 mM NaHS resulted better phenotype, growth and biomass production in Cd stressed plants. Protective stimulus of H2S regulated minerals and Cd homeostasis besides increased activity of antioxidants which decreased level of reactive oxygen species (ROS), EL, malondialdehyde (MDA) and MG in Cd regimes. Furthermore, H2S treated seedlings exhibited reduction in Cd content and revealed an active participation in the indole acetic acid (IAA) mediated pathway during stress. The findings of current study propose that H2S yimproved stress tolerance and mitigated Cd stress in B. rapa by modulating growth biomarkers and antioxidative system. (C) 2020 Elsevier Ltd.

Nanohybrid of ZnO-RGO as Heterogeneous Green Catalyst for the Synthesis of Medicinally Significant Indole Alkaloids and Their Derivatives

Nanohybrid of ZnO-RGO has been developed and employed as heterogeneous catalyst for the synthesis of medicinally significant organic scaffolds. In this work, the nanohybrid catalyst has been used for the one-pot synthesis of various indole alkaloids and their derivatives in good yields. Several molecules with different substitutions on heterocyclic ring have been synthesized to demonstrate the substrate scope and wide applicability of the catalyst. Indoles with both electron donating and electron withdrawing groups were found to be equally compatible and resulted in good yields. In addition, all the reactions have been performed in green reaction medium with ethanol and water as solvent and the absence of byproducts formed in the reaction makes the strategy Green and sustainable. Furthermore, the nanohybrid catalyst could be recycled multiple times without any significant loss in activity.

Induction of adventitious roots from leaf explants of Morinda coreia Buch. and ham. : an important dye yielding plant

The present communication reports, induction of adventitious roots (AR) from the in vitro raised leaves of Morinda coreia as affected by auxins and their varying concentrations. The roots of this plant possess anthraquinone, a preferable natural dye, explored well in pharmaceuticals. The AR from the leaves were induced under light and dark conditions within 5 weeks on half-strength Murashige and Shook’s (MS) medium. Among the various auxins and their concentrations tested, half-strength MS medium augmented with indole-3 butyric acid (IBA) at 4.0 mg/L was recorded most favorable in induction of AR (0.7997 gm fresh weight and 0.0698 gm dry weight) with negligible callus under dark conditions. The present study aimed to analyze the combined effect of light/dark and auxins on the induction of AR from the in vitro raised leaves of M. coreia. The protocol can be used for large scale proliferation of roots and enhanced production of dye (anthraquinones).

Organophosphorus-catalyzed relay oxidation of H-Bpin: electrophilic C-H borylation of heteroarenes

A nontrigonal phosphorus triamide (1, P{N[o-NMe-C6H4](2)}) is shown to catalyze C-H borylation of electron-rich heteroarenes with pinacolborane (HBpin) in the presence of a mild chloroalkane reagent. C-H borylation proceeds for a range of electron-rich heterocycles including pyrroles, indoles, and thiophenes of varied substitution. Mechanistic studies implicate an initial P-N cooperative activation of HBpin by 1 to give P-hydrido diazaphospholene 2, which is diverted by Atherton-Todd oxidation with chloroalkane to generate P-chloro diazaphospholene 3. DFT calculations suggest subsequent oxidation of pinacolborane by 3 generates chloropinacolborane (ClBpin) as a transient electrophilic borylating species, consistent with observed substituent effects and regiochemical outcomes. These results illustrate the targeted diversion of established reaction pathways in organophosphorus catalysis to enable a new mode of main group-catalyzed C-H borylation.

Cyclopiazonic acid induced p53-dependent apoptosis in the testis of mice: Another male related risk factor of infertility

Cyclopiazonic acid (CPA) is an indole tetrameric acid mycotoxin. This study carried out to investigate the potential effects of CPA on male reproductive system. In the current study, 40 adult male mice were divided into five groups (n = 8). The control group did not expose to CPA, while animals in vehicle-received group; received the CPA-solvent (0.05% dimethyl sulfoxide) and the animals of third, fourth, and fifth groups received CPA 0.03, 0.06, and 0.12 mg/kg, body weight, respectively for 28 days. Morphometric and morphological deviations, spermatogenesis indices, malondialdehyde (MDA) content, total thiol molecules (TTM) concentration, total antioxidant capacity (TAC), protein carbonylation rate (CO), and nitric oxide (NO) concentration were examined. The expression changes of apoptotic genes (P53, Bcl-2, and Caspase III) at mRNA level were also evaluated by qPCR technique. Reduction in the Leydig and Sertoli cells population, diameter of seminiferous tubules, and spermatogenesis parameters was significant only in the group that received the highest dose of CPA. An increase in the level of MDA, NO, and CO in testicular tissue and reduction of TAC and TTM were observed in the CPA-exposed groups. Significant up-regulation (p < .05) in the expression of P53 and Caspase III genes and down-regulation of Bcl-2 gene were found in the CPA-received groups. These results are indicating the detrimental effects of CPA on the testicles, which may attribute to the CPA-induced oxidative stress and apoptosis. Moreover, results also help to understand a serious concern about the presence of CPA in foods as a potential risk factor in male-related infertility. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 78415-72-2, in my other articles.

Effects of dietary cellobiose on the intestinal microbiota and excretion of nitrogen metabolites in healthy adult dogs

In order to evaluate the potential prebiotic effects of cellobiose, 10 healthy adult research beagle dogs received a complete diet containing 0, 0.5 and 1 g cellobiose/kg bodyweight (BW)/day. At the end of each feeding period, faeces, urine and blood of the dogs were collected. The results demonstrated a significant increase of faecal lactate concentrations, indicating a bacterial fermentation of cellobiose in the canine intestine. Along with this, a dose-dependent linear increase of the relative abundance of Lactobacillaceae in the faeces of the dogs was observed (p = 0.014). In addition, a dose-dependent increase (p < 0.05) of Alloprevotella, Bacteroides and Prevotella, and a linear decrease for unidentified Lachnospiraceae (p = 0.011) was observed when cellobiose was added to the diet, although the relative abundance of these genera was low (<1%) among all groups. The faecal pH was not affected by dietary cellobiose. Cellobiose seemed to modulate the excretion of nitrogen metabolites, as lower concentrations of phenol (p = 0.034) and 4-ethylphenol (p = 0.002) in the plasma of the dogs were measured during the supplementation periods. Urinary phenols and indoles, however, were not affected by the dietary supplementation of cellobiose. In conclusion, cellobiose seems to be fermented by the intestinal microbiota of dogs. Although no effect on the faecal pH was detected, the observed increase of microbial lactate production might lower the pH in the large intestine and consecutively modulate the intestinal absorption of nitrogen metabolites. Also, the observed changes of some bacterial genera might have been mediated by increased intestinal lactate concentrations or a higher relative abundance of lactobacilli. Whether these results could be considered as a prebiotic effect and used as a dietetic strategy in diseased animals to improve gut function or hepatic and renal nitrogen metabolism should be evaluated in future studies. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 88-04-0 help many people in the next few years.
