spiro-Cyclotriphosphazenes containing 4-hydroxyphenylethyl pendant arm: Syntheses, structural characterization and DNA interaction study

The reaction of hexachlorocyclotriphosphazene, N3P3Cl6, with tyramine podand (2) afforded partly substituted spiro-cyclotriphosphazene (3). Amine-substituted spiro-cyclotriphosphazenes 4a-g were prepared by substitution of the Cl-atoms in 3 with pyrrolidine, piperidine, morpholine, 1,4-dioxa-8-azaspiro[4,5]decane, 1-(2-aminoethyl)pyrrolidine, 1-(2-aminoethyl) piperidine, and 4-(2-aminoethyl)-morpholine, respectively. All of the cyclotriphosphazene derivatives were characterized by elemental analysis, FTIR, MS, 1D H-1, C-13 and P-31 NMR and 2D HSQC techniques, and the crystal structures of 3 and 4b were verified by X-ray diffraction analysis. The relationships delta P-OPN shifts with exocyclic OPN (alpha’) and endocyclic NPN (alpha) bond angles, and electron density transfer parameters Delta(P-N) for spiro-cyclotriphosphazenes were presented. The DNA cleavage activity of cyclotriphosphazene derivatives (3, and 4a-g) was studied on double-stranded pBR322 DNA using gel electrophoresis experiments. It was found that 4e and 4f caused the highest level of DNA damage. The interactions of 3 and 4e with calf thymus DNA were also investigated using absorption spectrometry. The molecular docking was performed to identify the interaction of the compounds (3 and 4b) with the DNA (PDB ID:3V9D for A-DNA and PDB ID:1BNA for B-DNA). (C) 2018 Elsevier B.V.

Antinociceptive effects of novel histamine H-3 and H-4 receptor antagonists and their influence on morphine analgesia of neuropathic pain in the mouse

Background and Purpose The histaminergic system is a promising target for the development of new analgesics, as histamine H-3 and H-4 receptors are expressed in regions concerned with nociceptive transmission. Here we have determined the analgesic effects of new H-3 and H-4 receptor antagonists in naive and neuropathic mice. Experimental Approach We used chronic constriction injury (CCI) to the sciatic nerve in mice to model neuropathy. Effects of a new H-3 receptor antagonist, E-162(1-(5-(naphthalen-1-yloxy)pentyl)piperidine) and H-4 receptor antagonist, TR-7(4-(4-chlorophenyl)-6-(4-methylpiperazin-1-yl)-1,3,5-triazin-2-amine) were assessed on mechanical (von Frey) and thermal (cold plate, tail flick) stimuli in mice with and without CCI (7days after injury). Effects of these antagonists on morphine analgesia were also evaluated, along with the possible participation of H-1 receptors in their effects. We analysed the compounds in binding and functional cAMP assays at the H-3 and H-4 receptors and determined metabolic stability. Key Results E-162 and TR-7 attenuated nociceptive responses and profound morphine analgesia in males with CCI. These antagonists showed analgesia in naive mice (tail flick test) and produced prolonged analgesia in neuropathic females. E-162-induced analgesia was reversed by pyrilamine, an H-1 receptor antagonist. E-162 bound potently to H-3 receptors (K-i=55nM) and inhibited cAMP accumulation (IC50=165nM). TR-7 showed lower affinity for H-4 receptors (K-i=203nM) and IC(50)of 512nM. Conclusions and Implications We describe a therapeutic use for new H-3 (E-162) and H-4 receptor (TR-7) antagonists in neuropathy. Targeting H-3 and H-4 receptors enhanced morphine analgesia, consistent with multimodal pain therapy.

Enantioselective Synthesis of alpha-(Hetero)aryl Piperidines through Asymmetric Hydrogenation of Pyridinium Salts and Its Mechanistic Insights

Enantioselective synthesis of alpha-aryl and alpha-heteroaryl piperidines is reported. The key step is an iridium-catalyzed asymmetric hydrogenation of substituted N-benzylpyridinium salts. High levels of enantioselectivity up to 99.3:0.7 er were obtained for a range of alpha-heteroaryl piperidines. DFT calculations support an outersphere dissociative mechanism for the pyridinium reduction. Notably, initial protonation of the final enamine intermediate determines the stereochemical outcome of the transformation rather than hydride reduction of the resultant iminium intermediate.

Regioselective Bronsted Acid-Catalyzed Annulation of Cyclopropane Aldehydes with N’-Aryl Anthranil Hydrazides: Domino Construction of Tetrahydropyrrolo[1,2-a]quinazolin-5(1H)ones

A highly regioselective synthesis of tetrahydropyrrolo[1,2-a]quinazolin-5(1H)one derivatives was achieved by reacting cyclopropane aldehydes with N’-aryl anthranil hydrazides in the presence of p-toluene sulfonic acid (PTSA). The transformation involves domino imine formation and intramolecular cyclization to form 2-arylcyclopropyl-2,3-dihydroquinolin-4(1H)-one, followed by nucleophilic ring opening of the cyclopropyl ring to form desired tetrahydropyrrolo [1,2-a]quinazolin-5(1H) one in good to excellent yield with complete regioselectivity. This protocol tolerates a great variety of functional groups and thus provides a simple and step-efficient method for pyrroloquinazolinone synthesis.

Strategy for Designing Selective Lysosomal Acid alpha-Glucosidase Inhibitors: Binding Orientation and Influence on Selectivity

Deoxynojirimycin (DNJ) is the archetypal iminosugar, in which the configuration of the hydroxyl groups in the piperidine ring truly mimic those ofd-glucopyranose; DNJ and derivatives have beneficial effects as therapeutic agents, such as anti-diabetic and antiviral agents, and pharmacological chaperones for genetic disorders, because they have been shown to inhibit alpha-glucosidases from various sources. However, attempts to design a better molecule based solely on structural similarity cannot produce selectivity between alpha-glucosidases that are localized in multiple organs and tissues, because the differences of each sugar-recognition site are very subtle. In this study, we provide the first example of a design strategy for selective lysosomal acid alpha-glucosidase (GAA) inhibitors focusing on the alkyl chain storage site. Our design of alpha-1-C-heptyl-1,4-dideoxy-1,4-imino-l-arabinitol (LAB) produced a potent inhibitor of the GAA, with an IC(50)value of 0.44 mu M. It displayed a remarkable selectivity toward GAA (selectivity index value of 168.2). A molecular dynamic simulation study revealed that the ligand-binding conformation stability gradually improved with increasing length of the alpha-1-C-alkyl chain. It is noteworthy that alpha-1-C-heptyl-LAB formed clearly different interactions from DNJ and had favored hydrophobic interactions with Trp481, Phe525, and Met519 at the alkyl chain storage pocket of GAA. Moreover, a molecular docking study revealed that endoplasmic reticulum (ER) alpha-glucosidase II does not have enough space to accommodate these alkyl chains. Therefore, the design strategy focusing on the shape and acceptability of long alkyl chain at each alpha-glucosidase may lead to the creation of more selective and practically useful inhibitors.

A series of 3S,4S,5S-trihydroxylated piperidines bearing structural diversity at C-2 or C-6 positions has been synthesized and tested to determine their ability to stabilize the activity of recombinant human alpha-Galactosidase A (rh-alpha-Gal A). Hit molecules were identified by rapid inhibitory activity screening, and then further investigated for their ability to protect this enzyme from thermo-induced denaturation and enhance its activity in Fabry patient cell lines. Our study resulted in the identification of a new class of small molecules as enzyme stabilizers for the potential treatment of Fabry disease. Of these, stabilizer 21 was the most effective, showing a 12-fold increase in rh-alpha-Gal A activity in Fabry disease cell lines. (C) 2017 Elsevier Masson SAS. All rights reserved.

Proteomic and metabolic profile analysis of low-temperature storage responses inIpomoea batataLam. tuberous roots

Background Sweetpotato (Ipomoea batatasL.) is one of the seven major food crops grown worldwide. Cold stress often can cause protein expression pattern and substance contents variations for tuberous roots of sweetpotato during low-temperature storage. Recently, we developed proteometabolic profiles of the fresh sweetpotatoes (cv. Xinxiang) in an attempt to discern the cold stress-responsive mechanism of tuberous root crops during post-harvest storage. Results For roots stored under 4 degrees C condition, the CI index, REC and MDA content in roots were significantly higher than them at control temperature (13 degrees C). The activities of SOD, CAT, APX, O(2)(.-)producing rate, proline and especially soluble sugar contents were also significantly increased. Most of the differentially expressed proteins (DEPs) were implicated in pathways related to metabolic pathway, especially phenylpropanoids and followed by starch and sucrose metabolism. L-ascorbate peroxidase 3 and catalase were down-regulated during low temperature storage. alpha-amylase, sucrose synthase and fructokinase were significantly up-regulated in starch and sucrose metabolism, while beta-glucosidase, glucose-1-phosphate adenylyl-transferase and starch synthase were opposite. Furthermore, metabolome profiling revealed that glucosinolate biosynthesis, tropane, piperidine and pyridine alkaloid biosynthesis as well as protein digestion and absorption played a leading role in metabolic pathways of roots. Leucine, tryptophan, tyrosine, isoleucine and valine were all significantly up-regulated in glucosinolate biosynthesis. Conclusions Our proteomic and metabolic profile analysis of sweetpotatoes stored at low temperature reveal that the antioxidant enzymes activities, proline and especially soluble sugar content were significantly increased. Most of the DEPs were implicated in phenylpropanoids and followed by starch and sucrose metabolism. The discrepancy between proteomic (L-ascorbate peroxidase 3 and catalase) and biochemical (CAT/APX activity) data may be explained by higher H(2)O(2)levels and increased ascorbate redox states, which enhanced the CAT/APX activity indirectly. Glucosinolate biosynthesis played a leading role in metabolic pathways. Leucine, tryptophan, tyrosine, isoleucine and valine were all significantly up-regulated in glucosinolate biosynthesis.

Transition-Metal-Free Functionalization of Saturated and Unsaturated Amines to Bioactive Alkaloids Mediated by Sodium Chlorite

New approaches to the synthesis of alkaloids through the straightforward functionalization of C(sp(3))-H and C(sp(2))=C(sp(2)) bonds of simple five- and six-membered-ring N-heterocycles are highlighted. The direct functionalization of pre-existing N-heterocycles to advanced alkaloids intermediates is a chemical operation that commonly requires the intervention of transition or precious metals. Regardless the inherent unwanted waste production, the high economical cost of many transition-metal catalysts limits their use globally. Here, we account our efforts directed toward the synthesis of bioactive alkaloids under an economic and ecological fashion by using NaClO2 as the key activating or oxidizing reagent that substitutes the use of transition-metal catalysts. While undesired metal wastes are collected during the extraction process of a transition-metal-catalyzed reaction, innocuous NaCl is the commonly product waste when NaClO2 is employed in our chemical transformations. Beginning with the synthesis of 2,3-epoxyamides from allyl amines, we concluded with the functionalization of multiple and remote C(sp(3))-H and C(sp(3))-C(sp(3)) bonds in piperidine rings that enabled the preparation of important bioactive alkaloids. For the latter functionalization, a precise amount of co-oxidant reagent (NaOCl) and radical 2,2,6,6-tetramethylpiperidinyloxy (TEMPO) were needed.

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 34737-89-8 help many people in the next few years. Formula: C13H17NO.

Synthesis of novel 2,5-substituted p-aminophenols and 2,5-substituted p-quinones in a one-pot reaction between alpha- alkoxyvinyl(ethoxy)carbene complexes, amines and alkynes

The synthesis of novel p-aminophenols 19a-o and p-quinones 21a-i was carried out by an aminolysis reaction/[3 + 2+1] cycloaddition cascade process of alpha-alkoxyvinyl (ethoxy) Fischer carbene complexes of group 6 metals (M = Cr, Mo, W), primary and secondary amines and terminal alkynes. The multicomponent reaction of carbenes la-c with morpholine (6a) and piperidine (6c), respectively, and terminal alkynes 17a-d only afforded the 4-aminophenols 19a-o in moderated yields. The products bore the terminal alkyne substituent at the ortho position of the hydroxyl group. These one-pot reactions showed highly regio- and chemoselectivity, favoring the benzannulation products. When carbene complexes la-c were reacted with primary amines 10a-c and alkynes 17a-c under the same conditions, the cascade process led to the formation of p-quinones 21a-21i, in moderate yields. The regiochemistry of the compounds was established by NOE experiments, and the structures of morpholinocarbene 7a, p-aminophenols 19b, 19d and p-quinone 21b were confirmed by single-crystal X-ray diffraction.
