Synthesis of indole-3-acetic acid and indole-3-butyric acid loaded zinc oxide nanoparticles: Effects on rhizogenesis

The aim of this work was to investigate the use of zinc oxide nanoparticles (nZnO) as nanocarriers for plant auxins indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) and determine the effects on rhizogenesis in micro cuttings of different Pyrus species. Auxin loaded nanoparticles (IAA-nZnO and IBA-nZnO) were characterized for particle size, morphology, thermal behavior and chemical structure. A high loading capacity was observed for both auxins ((similar to)90%). Bioactivity assays were performed by using micro cuttings of Pyrus genotypes (Pyrus elaeagrifolia Pall and Pyrus communis L.) under aseptic conditions by dilute solution soaking method. In vitro rooting efficiency was increased at least two folds for the difficult-to-root wild pear (Pyrus elaeagrifolia Pallas) with IAA or IBA loaded ZnO nanoparticles. In this genotype, the highest rooting percentage was achieved for IBA-nZnO and IAA-nZnO at 400 mgL(-1) concentration as 50.0% and 41.7%, respectively. Thus, auxin loaded ZnO nanoparticles could be used as efficient nanocarriers in agricultural applications.

2D-2D Nanocomposite of MoS2-Graphitic Carbon Nitride as Multifunctional Catalyst for Sustainable Synthesis of C3-Functionalized Indoles

A nanocomposite of two-dimensional MoS2 supported on graphitic C3N4 nanosheets has been prepared by a facile ultrasonication method followed by demonstrating its ability to catalyze the synthesis of several indole derivatives. The as-prepared nanocomposite catalyst was characterized in detail by using different microscopic and spectroscopic techniques to understand its structure and physicochemical properties. Subsequently, this nanocomposite catalyst was used as a heterogeneous multifunctional catalyst to synthesize several C3-functionalized indoles in the aqueous medium. The employed strategy also provided very good catalyst recyclability and versatility for the synthesis of various precursors of medicinally significant indoles, such as serotonin, melatonin, and various alpha-carboline alkaloids. In addition, a natural product derivate has been prepared on the gram-scale by using this methodology. Furthermore, high atom economy (100%) and lower E-factor (0.042) makes this strategy a sustainable approach for the synthesis of C3-functionalized indoles.

Dehydration stress memory: Insights from physiological responses of sugar apple (Annona squamosa L.) to repeated dehydration stress

Introduction – Evidence from drought hardening as a horticultural practice has demonstrated that exposing plants to repeated dehydration stress alters their physiological responses. Here we investigated the influence of repeated dehydration stress on physiological responses related to dehydration stress memory display in sugar apple. Materials and methods – Sugar apple seedlings were subjected to two successive bouts of dehydration stress with a recovery period in between, while seedlings watered throughout were an untreated control. Results – In the dehydration-stressed seedlings, concentrations of abscisic acid (ABA), indole-3-acetic acid (IAA), jasmonic acid (JA), jasmonoyl-L-isoleucine (JA-Ile), proline and malondialdehyde (MDA) were significantly higher than in the untreated control. On the other hand, the leaf water potential, stomata! conductance, and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity were lower in the treated seedlings, although the changes in total chlorophyll were insignificant. Furthermore, the seedlings displayed stress memory as demonstrated by accumulations of IAA and JA-Ile, an increase in MDA concentration, and decreases in total chlorophyll concentration, DPPH free radical scavenging activity, and leaf water potential in the second dehydration stress (S2) compared to the first stress (Si), indicating memory-mediated physiological responses. Meanwhile, ABA, JA, stomatal conductance, and proline concentration exhibited non-memory-mediated responses. Conclusion – These results suggest that accumulations of IAA and JA-Ile during repeated dehydration stress play significant roles as memory-mediated physiological responses for survival in sugar apple.

Persistent metabolomic alterations characterize chronic critical illness after severe trauma

BACKGROUND Following trauma, persistent inflammation, immunosuppression, and catabolism may characterize delayed recovery or failure to recover. Understanding the metabolic response associated with these adverse outcomes may facilitate earlier identification and intervention. We characterized the metabolic profiles of trauma victims who died or developed chronic critical illness (CCI) and hypothesized that differences would be evident within 1-week postinjury. METHODS Venous blood samples from trauma victims with shock who survived at least 7 days were analyzed using mass spectrometry. Subjects who died or developed CCI (intensive care unit length of stay of >= 14 days with persistent organ dysfunction) were compared with subjects who recovered rapidly (intensive care unit length of stay, <= 7 days) and uninjured controls. We used partial least squares discriminant analysis, t tests, linear mixed effects regression, and pathway enrichment analyses to make broad comparisons and identify differences in metabolite concentrations and pathways. RESULTS We identified 27 patients who died or developed CCI and 33 who recovered rapidly. Subjects were predominantly male (65%) with a median age of 53 years and Injury Severity Score of 36. Healthy controls (n = 48) had similar age and sex distributions. Overall, from the 163 metabolites detected in the samples, 56 metabolites and 21 pathways differed between injury outcome groups, and partial least squares discriminant analysis models distinguished injury outcome groups as early as 1-day postinjury. Differences were observed in tryptophan, phenylalanine, and tyrosine metabolism; metabolites associated with oxidative stress via methionine metabolism; inflammatory mediators including kynurenine, arachidonate, and glucuronic acid; and products of the gut microbiome including indole-3-propionate. CONCLUSIONS The metabolic profiles in subjects who ultimately die or develop CCI differ from those who have recovered. In particular, we have identified differences in markers of inflammation, oxidative stress, amino acid metabolism, and alterations in the gut microbiome. Targeted metabolomics has the potential to identify important metabolic changes postinjury to improve early diagnosis and targeted intervention.

Rhodium(III)-Catalyzed Regioselective Direct C4-Alkylation and C2-Annulation of Indoles: Straightforward Access to Indolopyridone

A straightforward Rh-III-catalyzed strategy was developed for the site-selective C4-alkylation and C2-annulation of indole by using electronically variable diazo esters. The transformation was accomplished with the assist of an oxime directing group at the C3 position of the indole core with wide scope and functional-group tolerance. The method directly provided an indolopyridone core. The selectivity was triggered by the reactivity of the diazo coupling partner.

Research progress of near-infrared fluorescence probes based on indole heptamethine cyanine dyes in vivo and in vitro

Near-infrared (NIR) fluorescence imaging is a noninvasive technique that provides numerous advantages for the real-time in vivo monitoring of biological information in living subjects without the use of ionizing radiation. Near-infrared fluorescent (NIRF) dyes are widely used as fluorescent imaging probes. These fluorescent dyes remarkably decrease the interference caused by the self-absorption of substances and autofluorescence, increase detection selectivity and sensitivity, and reduce damage to the human body. Thus, they are beneficial for bioassays. Indole heptamethine cyanine dyes are widely investigated in the field of near-infrared fluorescence imaging. They are mainly composed of indole heterocyclics, heptamethine chains, and N-substituent side chains. With indole heptamethine cyanine dyes as the parent, introducing reactive groups to the parent compounds or changing their structures can make fluorescent probes have different functions like labeling protein and tumor, detecting intracellular metal cations, which has become the hotspot in the field of fluorescence imaging of biological research. Therefore, this study reviewed the applications of indole heptamethine cyanine fluorescent probes to metal cation detection, pH, molecules, tumor imaging, and protein in vivo. The distribution, imaging results, and metabolism of the probes in vivo and in vitro were described. The biological application trends and existing problems of fluorescent probes were discussed.
