A remarkable adsorbent for removal of nitrogenous compounds from fuel: A metal-organic framework functionalized both on metal and ligand

Efficient elimination of nitrogenous compounds (NCs) from fuel is an important issue. Recently, metal organic frameworks (MOFs), both pristine and modified ones, have attracted continuous attention as an adsorbent for the purification of fuel. In this study, we used, for the first time, MOFs functionalized on both metal (via coordination on open metal site) and ligand, in the purification of fuel. A highly stable MOF, MIL-101(Cr), was modified to introduce amino groups both on the ligand and metal sites, and the NH2-MIL-101 was further reacted with oxalyl chloride to obtain a multifunctional adsorbent named OC-ED-A-M101. This adsorbent showed an outstanding performance in adsorptive denitrogenation of fuels. Or, the OC-ED-A-M101 had 11.7 and 9.3 times adsorption capacity for indole and quinoline, respectively, that of an activated carbon. Moreover, the new adsorbent showed the highest and the second highest adsorption capacity for indole and quinoline, respectively, compared with any reported MOF-based adsorbents. The noticeable performances of OC-ED-A-M101 could be interpreted with H-bonding because of ample hydrogen donor and hydrogen acceptor sites on the OC-ED-A-M101. Adsorption over other M101s could be explained with the combination of H-bonding, acid-base interaction, and base-base repulsion. Finally, the studied MOF could be easily reactivated by washing with ethanol. Therefore, OC-ED-A-M101 might be a potential adsorbent for the purification of fuel containing NCs.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 2447-57-6, you can contact me at any time and look forward to more communication. Formula: C12H14N4O4S.

Effect of nitrate on indole degradation characteristics and methanogenesis under mixed denitrification and methanogenesis culture

Batch experiments were conducted to investigate the effect of nitrate on indole degradation characteristics and methanogenesis under mixed denitrification and methanogenesis culture for the first time. The degradation characteristics were studied under various nitrate concentrations. Nitrate was found to facilitate indole degradation and inhibit methane formation, and the optimum concentration was 50 mg L-1. (COD/NO3–N = 12). Balance analyses showed that nitrate mainly affected indole-C, which generated a higher degree of indole mineralization under NO3–N treatment than in the control. Furthermore, GC-MS combined with C-13-isotope analyses conclusively identified the intermediate metabolites, which included the hydroxylated compounds oxindole and isatin, and the methylated compound 3-methylindole. The results indicated that oxindole did not accumulate and was quickly reduced when nitrate was added, but 3-methylinole, as a recalcitrant material, accumulated without reduction. High-throughput sequencing technology was used to analyse the dynamic microbial community. Results showed that the denitrifying bacterial genera Acinetobacter, Candidimonas and Longilinea accumulated in denitrification stage and decreased in methanogenesis stage, whereas the fermentation genera Alcaligenes and Thermogutta increased in methanogenesis stage. The genera Methanosphaerula and Methanothrix constituted the dominant archaeal communities. The findings obtained in this work may provide a theoretical basis for treatment with N-heterocyclic compounds under mixed culture.

Chemical Diversity and Bioactivities of Monoterpene Indole Alkaloids (MIAs) from Six Apocynaceae Genera

By the end of the twentieth century, the interest in natural compounds as probable sources of drugs has declined and was replaced by other strategies such as molecular target-based drug discovery. However, in the recent times, natural compounds regained their position as extremely important source drug leads. Indole-containing compounds are under clinical use which includes vinblastine and vincristine (anticancer), atevirdine (anti-HIV), yohimbine (erectile dysfunction), reserpine (antihypertension), ajmalicine (vascular disorders), ajmaline (anti-arrhythmic), vincamine (vasodilator), etc. Monoterpene Indole Alkaloids (MIAs) deserve the curiosity and attention of researchers due to their chemical diversity and biological activities. These compounds were considered as an impending source of drug-lead. In this review 444 compounds, were identified from six genera belonging to the family Apocynaceae, will be discussed. These genera (Alstonia, Rauvolfia, Kopsia, Ervatamia, and Tabernaemontana, and Rhazya) consist of 400 members and represent 20% of Apocynaceae species. Only 30 (7.5%) species were investigated, whereas the rest are promising to be investigated. Eleven bioactivities, including antibacterial, antifungal, anti-inflammatory and immunosuppressant activities, were reported. Whereas cytotoxic effect represents 47% of the reported activities. Convincingly, the genera selected in this review are a wealthy source for future anticancer drug lead.

Ammonia generation by tryptophan synthase drives a key genetic difference between genital and ocular Chlamydia trachomatis isolates

A striking difference between genital and ocular clinical isolates of Chlamydia trachomatis is that only the former express a functional tryptophan synthase and therefore can synthesize tryptophan by indole salvage. Ocular isolates uniformly cannot use indole due to inactivating mutations within tryptophan synthase, indicating a selection against maintaining this enzyme in the ocular environment. Here, we demonstrate that this selection occurs in two steps. First, specific indole derivatives, produced by the human gut microbiome and present in serum, rapidly induce expression of C trachomatis tryptophan synthase, even under conditions of tryptophan sufficiency. We demonstrate that these indole derivatives function by acting as de-repressors of C trachomatis TrpR. Second, tip operon derepression is profoundly deleterious when infected cells are in an indole-deficient environment, because in the absence of indole, tryptophan synthase deaminates serine to pyruvate and ammonia. We have used biochemical and genetic approaches to demonstrate that expression of wild-type tryptophan synthase is required for the bactericidal production of ammonia. Pertinently, although these indole derivatives de-repress the trpRBA operon of C. trachomatis strains with trpA or trpB mutations, no ammonia is produced, and no deleterious effects are observed. Our studies demonstrate that tryptophan synthase can catalyze the ammonia-generating beta-elimination reaction within any live bacterium. Our results also likely explain previous observations demonstrating that the same indole derivatives inhibit the growth of other pathogenic bacterial species, and why high serum levels of these indole derivatives are favorable for the prognosis of diseased conditions associated with bacterial dysbiosis.

Indole-3-Acetic Acid Synthesis by Plant Growth Promoting Klebsiella sp. (PGPB1) via Indole-3-Pyruvic Acid Pathway and its Uptake in Plants

N-15-labeled tryptophan was used to trace the synthesis of indole-3-acetic acid (IAA) by plant growth promoting Klebsiella sp. (PGPB1). Preliminary thin layer chromatography analysis of crude extracts showed that IAA was produced from labeled tryptophan. This is further supported by high pressure liquid chromatography wherein the components of the crude extracts separated to two major peaks corresponding to indole-3-acetic acid (IAA) and indole-3-pyruvic acid (IPyA). Using Salkowski colorimetric assay, the extract was found to contain 11.81 +/- 5.98 x 10(-3) ppm of IAA and 56.91 +/- 0.35 ppm of IPyA. The crude extract, IAA and IPyA fractions were found to be enriched with N-15. Likewise, the presence of higher concentration of IPyA in the extract indicates that PGPB1 is probably using the IPyA pathway in synthesizing IAA. Rice seedlings germinated and grown in the N-15-labeled IAA produced by PGPB1 showed significant differences from the control treatment in terms of higher fresh weight, root length, and shoot length. Rice seedlings were also found to be enriched in N-15, confirming that they were able to take up the applied N-15 -labeled IAA.

Iridium-Catalyzed Enantioselective Intermolecular Indole C2-Allylation

The enantioselective intermolecular C2-allylation of 3-substituted indoles is reported for the first time. This directing group-free approach relies on a chiral Ir-(P, olefin) complex and Mg(ClO4)(2) Lewis acid catalyst system to promote allylic substitution, providing the C2-allylated products in typically high yields (40-99 %) and enantioselectivities (83-99 % ee) with excellent regiocontrol. Experimental studies and DFT calculations suggest that the reaction proceeds via direct C2-allylation, rather than C3-allylation followed by in situ migration. Steric congestion at the indole-C3 position and improved pi-pi stacking interactions have been identified as major contributors to the C2-selectivity.
