Structure Revisions of the Sponge-Derived Dibrominated Bis-indole Alkaloids, Echinosulfone A and the Echinosulfonic Acids A to D

The structures of the sponge-derived dibrominated bisindole alkaloids, namely, echinosulfone A (2) and the echinosulfonic acids A to D (9-12), have been revised based upon reanalysis of their NMR spectroscopic and MS spectrometric data, comparison of this data with those reported for structurally related compounds, and based on their common biogenesis. The reinterpreted spectroscopic evidence has been corroborated by the total synthesis of the revised structure of echinosulfone A (2). This was achieved by bis-carbonylation at C-3 of the magnesium salt of 6-bromoindole with triphosgene to afford the new dibrominated bis-indole ketone, bis(6-bromo-1H-indol-3-yl)methanone (3), followed by N-sulfonation of one indole moiety to furnish 6-bromo-3-(6-bromo-1H-indole-3-carbonyl)-1H-indole-1-sulfonate (2). The five marine alkaloids corrected herein each contain an indole sulfamate and are all carbon-bridged dibrominated bis-indoles: echinosulfone A (2) is a di(1H-indol-3-yl)methanone, while the echinosulfonic acids A to D (9-12) are methyl 2,2-bis(1H-indol-3-yl) acetates.

Profiles of endogenous ABA, bioactive GAs, IAA and their metabolites in Medicago truncatula Gaertn. non-embryogenic and embryogenic tissues during induction phase in relation to somatic embryo formation

Main conclusionDuring the 3-week-long induction phase, when M. truncatula cells leaf explants from non-embryogenic genotype (M9) and embryogenic variant (M9-10a) were forming the callus, biosynthesis and degradation of ABA, Gas and IAA proceeded at different levels. Induction of embryo formation is related to a lower ABA content, compared to the content of IAA and that of total bioactive GAs.AbstractEndogenous phytohormones are involved in the regulation of zygotic embryogenesis, but their role, especially of ABA, a plant growth inhibitor, in inducing somatic embryogenesis (SE) in angiosperms is still incompletely known. To arrive a better understanding of the ABA role in the process, we analyzed simultaneously and in detail changes in the contents of both ABA and five bioactive GAs (GA(4,) GA(7,) GA(1), GA(3,) GA(6)) and IAA in M. truncatula non-embryogenic M9 (NE) and embryogenic M9-10a (E) genotypes. The initial leaf explants of both genotypes, and particularly NE, contained many times more ABA compared to the total bioactive GAs or IAA. In tissues during the entire 21-day induction all the hormones mentioned and their metabolites or conjugates were present; however, their contents were found to differ between the lines tested. The ABA level in primary explants of NE genotype was more than two times higher than that in E genotype. An even larger difference in the ABA content was found on the last day (day 21) of the induction phase (IP); the ABA content in E callus was over six times lower than in NE callus. In contrast, the IAA and GAs contents in primary explants of both genotypes in relation to ABA were low, but the contents of IAA and GAs exceeded that of ABA in the M9-10a tissues on the last day of IP. It is shown for the first time that endogenous ABA together with endogenous bioactive GAs and IAA is involved in acquisition of embryogenic competence in Medicago truncatula leaf somatic cells. These findings have a strong functional implication as they allow to improve the SE induction protocol.

Fuzzy synthetic evaluation of the impact of plant growth regulators on the root phenotype traits of rice seedlings under thiocyanate stress

Application of plant growth regulators (PGRs) is a novel strategy for allay of the adverse effects caused by biotic/abiotic stresses. However, no studies have vividly executed mathematic evaluation for the assessment of various PGRs on root phenotype traits (RPTs) against pollutants. In the present study, a microcosm hydroponic experiment was conducted to examine responses of RPTs under SCN- (0, 24, 96, and 300 mg SCN/L) stress in the presence of PGRs such as jasmonic acid (JA), indole-3-acetic acid (IAA), and sodium hydrosulfide (NaHS) in rice plants. Fuzzy synthetic evaluation was applied to determine the outcome of the effects of various PGRs on the RPTs under SCN- exposure. Root scanning results indicated that exogenous IAA and NaHS has the greater potential for improving the RPTs of rice seedlings under SCN – stress, while JA failed to uplift the RPTs in response to SCN- stress. Fuzzy synthetic evaluation indicated that in control plants (without SCN ), the effect of three PGRs applied on the RPTs is as follows: NaHS > IAA > JA. At 24 mg SCN/L, NaHS and IAA had consistent actuate in regulating RPTs of rice seedlings, while all PGRs amended have an affirmative impact on RPTs at 96 and 300 mg SCN/L. The present research highlights the utilization of contemporary mathematic method to screen the superior species of PGRs through the RPTs test of plants under pollutant belt.

Structural insights into the design of indole derivatives as tubulin polymerization inhibitors

Microtubules are composed of alpha beta-tubulin heterodimers, and drugs that interfere with microtubule dynamics are used widely in cancer chemotherapy. Small synthetic molecules with an indole nucleus as a core structure have been identified as microtubule inhibitors and recognized as anticancer agents. However, structural information for the interactions between indole derivatives and tubulin is sparse. Here, we present the 2.55 angstrom crystal structure of tubulin in complex with the indole derivative D64131. We compare the binding modes of D64131, colchicine, and five other indole derivatives to tubulin. These results reveal the interactions between the indole derivatives and tubulin, explain previous results of structure-activity-relationship (SAR) studies and, thus, provide insights into the development of new indole derivatives targeting the colchicine binding site.

Metabolomics profile of Japanese female patients with restricting-type anorexia nervosa

In this study, the serum metabolic profiles of 10 female patients with restricting type anorexia nervosa (ANR) were compared to those of 10 age-matched healthy female controls. While the levels of amino acids were lower among the patients than among the controls, the levels of uremic toxins, including p-cresyl sulfate (PCS), indole-3-acetic acid, and phenyl sulfate, were higher in ANR patients. The serum PCS levels correlated positively with the abundance of the Clostridium coccoides group or the C. leptum subgroup in the feces of patients, but not in those of controls. Collectively, these results indicate that the serum metabolic profiles of patients with ANR differ from those of healthy women in terms of both decreased amino acid levels and increased uremic toxins. Gut microbes including C. coccoides or C. leptum may be involved in such an increase in uremic toxins.

Indoles derived from intestinal microbiota act via type I interferon signaling to limit graft-versus-host disease

The intestinal microbiota in allogeneic bone marrow transplant (allo-BMT) recipients modulates graft-versus-host disease (GVHD), a systemic inflammatory state initiated by donor T cells that leads to colitis, a key determinant of GVHD severity. Indole or indole derivatives produced by tryptophan metabolism in the intestinal microbiota limit intestinal inflammation caused by diverse stressors, so we tested their capacity to protect against GVHD in murine major histocompatibility complex-mismatched models of allo-BMT. Indole effects were assessed by colonization of allo-BMT recipient mice with tryptophanase positive or negative strains of Escherichia coli, or, alternatively, by exogenous administration of indole-3-carboxaldehyde (ICA), an indole derivative. Treatment with ICA limited gut epithelial damage, reduced transepithelial bacterial translocation, and decreased inflammatory cytokine production, reducing GVHD pathology and GVHD mortality, but did not compromise donor T-cell-mediated graft-versus-leukemia responses. ICA treatment also led to recipient-strain-specific tolerance of engrafted T cells. Transcriptional profiling and gene ontology analysis indicated that ICA administration upregulated genes associated with the type I interferon (IFN1) response, which has been shown to protect against radiation-induced intestinal damage and reduce subsequent GVHD pathology. Accordingly, protective effects of ICA following radiation exposure were abrogated in mice lacking IFN1 signaling. Taken together, these data indicate that indole metabolites produced by the intestinal microbiota act via type I IFNs to limit intestinal inflammation and damage associated with myeloablative chemotherapy or radiation exposure and acute GVHD, but preserve antitumor responses, and may provide a therapeutic option for BMT patients at risk for GVHD.
