F.;Unzeta, Mercedes;Marco-Contelles, Jose;Majekova, Magdalena;Ramsay, Rona R.;Carreiras, M. Carmo research published 《 Synthesis, biological evaluation, and molecular modeling of nitrile-containing compounds: Exploring multiple activities as anti-Alzheimer agents》, the research content is summarized as follows. Based on the monoamine oxidase (MAO) inhibition properties of aminoheterocycles with a carbonitrile group we have carried out a systematic exploration to discover new classes of carbonitriles endowed with dual MAO and AChE inhibitory activities, and Aβ anti-aggregating properties. Eighty-three nitrile-containing compounds, 13 of which are new, were synthesized and evaluated. In vitro screening revealed that 31, a new compound, presented the best lead for trifunctional inhibition against MAO A (0.34μM), MAO B (0.26μM), and AChE (52μM), while 32 exhibited a lead for selective MAO A (0.12μM) inhibition coupled to AChE (48μM) inhibition. Computational anal. revealed that the malononitrile group can find an advantageous position with the aromatic cleft and FAD of MAO A or MAO B. However, the total binding energy can be handicapped by an internal penalty caused by twisting of the ligand mol. and subsequent disruption of the conjugation (32 in MAO B compared to the conjugated 31). Conjugation is also important for AChE as well as the hydrophilic character of malononitrile that allows this group to be in close contact with the aqueous environment as seen for 83. Although the effect of 31 and 32 against Aβ_1-42, was very weak, the effect of 63 and 65, and of the new compound 75, indicated that these compounds were able to disaggregate Aβ_1-42 fibrils. The most effective was 63, a (phenylhydrazinylidene)propanedinitrile derivative that also inhibited MAO A (1.65μM), making it a potential lead for Alzheimer’s disease application.

Previously, we found (2Z,4E)-5-phenylpenta-2,4-dienoic acid (ku-76) to be a selective inhibitor of root gravitropic bending of lettuce radicles at 5μM, with no concomitant growth inhibition, and revealed the structure-activity relationship in this inhibitory activity. The conformation of ku-76 is flexible owing to the open-chain structure of pentan-2,4-dienoic acid with freely rotating single bonds, and the (2Z)-alkene moiety may be isomerized by external factors. To develop more potent inhibitors and obtain insight into the target biomols., various analogs of ku-76, fixed through conformation and/or configuration, were synthesized and evaluated. Stereochem. fixation was effective in improving the potency of gravitropic bending inhibition. Finally, we found highly potent conformational and/or configurational analogs (ku-257, ku-294 and ku-308), that did not inhibit root growth. The inhibition of root curvature by these analogs was comparable to that of naptalam.

Shi, Xiaolin;Wang, Zemin;Li, Yuxiu;Li, Xiaowei;Li, Xiangqian;Shi, Dayong research published 《 Palladium-Catalyzed Remote C-H Phosphonylation of Indoles at the C4 and C6 Positions by a Radical Approach》, the research content is summarized as follows. Palladium-catalyzed direct C-H activation of indole benzenoid moiety has been achieved in the past decade. However, palladium-catalyzed remote C-H activation of indoles is rare. Herein, we report a challenging palladium-catalyzed remote C4-H phosphonylation of indoles by a radical approach. The method provides access to a series of C4-phosphonylated indoles, including tryptophan and tryptophan-containing dipeptides, which are typically inaccessible by direct C4-H activation due to its heavy reliance on C3 directing groups. Notably, unexpected C6-phosphonylated indoles were obtained through blocking of the C4 position. The preliminary mechanistic studies indicated that the reactions may proceed via a C7-palladacycle/remote-activation process. Based on the strategy, examples of remote C4-H difluoromethylation with BrCF₂COOEt are also presented, suggesting that the strategy may offer a general blueprint for other cross-couplings.

Sedlacko, Erin M.;Heuberger, Adam L.;Chaparro, Jaqueline M.;Cath, Tzahi Y.;Higgins, Christopher P. research published 《 Metabolomics reveals primary response of wheat (Triticum aestivum) to irrigation with oilfield produced water》, the research content is summarized as follows. The reuse of oilfield produced water (PW) for agricultural irrigation has received increased attention for utility in drought-stricken regions. It was recently demonstrated that PW irrigation can affect physiol. processes in food crops. However, metabolomic evaluations are important to further discern specific mechanisms of how PW may contribute as a plant-environmental stressor. Herein, the primary metabolic responses of wheat irrigated with PW and matching salinity controls were investigated. Non-targeted gas chromatog. mass spectrometry (GC-MS) metabolomics was combined with multivariate anal. and revealed that PW irrigation altered the primary metabolic profiles of both wheat leaf and grain. Over 600 compounds (183 annotated metabolites) were detected that varied between controls (salinity control and tap water) and PW irrigated plants. While some of these changed metabolites are related to salinity stress, over half were found to be unique to PW. The primary metabolites exhibiting changes in abundance in leaf and grain tissues were amines/amino acids, organic acids, and saccharides. Metabolite pathway anal. revealed that amino acid metabolism, sugar metabolism, and nitrogen remobilization are all impacted by PW irrigation, independent of regular plant responses to salinity stress. These data, when combined with prior physiol. studies, support a multi-faceted, physio-metabolic response of wheat to the unique stressor imposed by irrigation with PW.

Electric Literature of 771-51-7, 3-Indoleacetonitrile is a plant growth activator, which promotes callus growth and shoot formation in tobacco callus.
3-Indoleacetonitrile (Indolylacetonitrile) is a light-induced auxin-inhibitory substance that is isolated from light-grown cabbage (Brassica olearea L.) shoots. It inhibits the biofilm formation of both E. coli O157:H7 and P. aeruginosa without affecting its growth.
3-Indoleacetonitrile, also known as 3-(cyanomethyl)indole or IAN, belongs to the class of organic compounds known as 3-alkylindoles. 3-alkylindoles are compounds containing an indole moiety that carries an alkyl chain at the 3-position. 3-Indoleacetonitrile exists as a solid and is considered to be practically insoluble (in water) and relatively neutral. Within the cell, 3-indoleacetonitrile is primarily located in the mitochondria. 3-Indoleacetonitrile participates in a number of enzymatic reactions. In particular, 3-indoleacetonitrile can be biosynthesized from acetonitrile. 3-Indoleacetonitrile is also a parent compound for other transformation products, including but not limited to, cys(ian)-gly, gammaglucys(ian), and L-cys(ian). Outside of the human body, 3-indoleacetonitrile can be found in a number of food items such as cloudberry, japanese persimmon, horned melon, and evergreen huckleberry. This makes 3-indoleacetonitrile a potential biomarker for the consumption of these food products.
Indole-3-acetonitrile is a nitrile that is acetonitrile where one of the methyl hydrogens is substituted by a 1H-indol-3-yl group. It has a role as an auxin, a plant hormone, a plant metabolite and a human xenobiotic metabolite. It is a nitrile and a member of indoles. It derives from an acetonitrile., 771-51-7.
