Piperidine-4-carboxamide as a new scaffold for designing secretory glutaminyl cyclase inhibitors

Alzheimer’s disease (AD), a common chronic neurodegenerative disease, has become a major public health concern. Despite years of research, therapeutics for AD are limited. Overexpression of secretory glutaminyl cyclase (sQC) in AD brain leads to the formation of a highly neurotoxic pyroglutamate variant of amyloid beta, pGluAp, which acts as a potential seed for the aggregation of full length A beta. Preventing the formation of pGlu-A beta through inhibition of sQC has become an attractive disease-modifying therapy in AD. In this current study, through a pharmacophore assisted high throughput virtual screening, we report a novel sQC inhibitor (Cpd-41) with a piperidine-4-carboxamide moiety (IC50 = 34 mu M). Systematic molecular docking, MD simulations and X-ray crystallographic analysis provided atomistic details of the binding of Cpd-41 in the active site of sQC. The unique mode of binding and moderate toxicity of Cpd-41 make this molecule an attractive candidate for designing high affinity sQC inhibitors. (C) 2020 Elsevier B.V. All rights reserved.

Collision-induced dissociation of protonated fentanyl: A DFT study

The fragmentation pathways leading to the major products resulting from collision-induced dissociation of protonated fentanyl are investigated. Starting from a protonated fentanyl in a twist conformation, transfer of the proton from the piperidine to the amide nitrogen allows the lone pair of the piperidine nitrogen to assist in displacement of the amide group and results in ring-opening of the piperidine to yield an ion with m/z 188 (C13H18N+). This is the fragmentation pathway with the lowest energy barrier; the barrier to the loss of the phenethyl group as a phenonium or 1-phenylethyl cation from the nitrogen in the piperidine ring is 64 kJ mol(-1) higher in energy. At even higher collision energies a bicyclic ion, also with nominal m/z 188 but with different elemental composition (C12H14NO+), is formed after sequential losses of ethene and phenethylamine from protonated fentanyl. Possible pathways to ring opening of the piperidine ring of N-protonated fentanyl include nucleophilic attack by the amide oxygen or the phenyl ring on the piperidine ring. The two m/z 188 ions give different dissociation products; minor products in the mass spectrum of protonated fentanyl at m/z 146, 134 and 132 are all generated from the dominant m/z 188 ion, C13H18N+, whereas only a product at m/z 132 is formed from the C12H14NO+ ion.

Ligand-Controlled Regioselective Pd-Catalyzed Diamination of Alkenes

A ligand-controlled system has been disclosed for the regioselective palladium-catalyzed diamination of unactivated alkenes, which provides an easy access to a variety of aminofunctionalized piperidines and pyrrolidines. The steric hindrance of ligands controlled the regioselectivtities of products. 6-Endo diamination occurred with less sterically hindered quinox ligand to afford 3-aminopiperidines, while 5-exo diamination occurred with sterically bulky pyox ligand to give amino-substituted pyrrolidines.

Evaluation of Ethylated Phenylcarbamoylazinane-1,2,4-Triazole Amides Derivatives as 15-Lipoxygenase Inhibitors Together with Cytotoxic, ADME and Molecular Modeling Studies

Searching the organic compound as anti-inflammatory agent is a fruitful effort to treat inflammatory disorders such as asthma, arthritis, psoriasis, and especially cancer. These disorders can be cured by lipoxygenase (LOX) inhibitors, which have the ability to stop the development and progression of inflammation. The present research described the synthesis of fifteen new N-alkyl/aralkyl/aryl derivatives (7 a-o) of 2-(4-ethyl-5-(1-phenylcarbamoyl)piperidine-4H-1,2,4-triazol-3-ylthio)acetamide by the continuous conversions of ethyl piperidine-4-carboxylate (a) into phenylcarbamoyl derivative (1) hydrazide (2), semicarbazide (3) and finally the N-ethylated 5-(1-phenylcarbamoyl)piperidine-1,2,4-triazole (4). The target molecules (7 a-o) were formed by the reaction of 4 with various electrophiles (6 a-o), in methanolic potassium hydroxide. These synthetic analogues were characterized by FTIR, H-1, C-13 NMR spectroscopy, EIMS, and HREIMS spectrometry. The compounds 7 a-o were screened for their inhibitory potential against 15-lipoxygenase. Compounds 7 b, 7 e, 7 c and 7 g displayed the potent inhibitory potential (IC50 17.52 +/- 0.67, 35.61 +/- 0.81, 36.24 +/- 0.83 & 36.52 +/- 0.58 mu M, respectively), whereas, moderate inhibition was shown by 7 h, 7 a, 7 d with IC50 values between 42.95 +/- 0.73 to 45.67 +/- 0.75 mu M, respectively. Some compounds exhibited drug-like characteristics due to their lower cytotoxic and good ADME profiles and supported by molecular modeling studies where one of the NH groups was found engaged through hydrogen bonding with Ala672. The carbonyl group amide and Asn554 were connected by a hydrogen bond, whereas the second NH group was also linked through hydrogen bonds with Gln363.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4005-49-6 is helpful to your research. Safety of N-(7H-Purin-6-yl)benzamide.

Isolation, leishmanicidal evaluation and molecular docking simulations of piperidine alkaloids from Senna spectabilis

Leishmaniasis is one of the most important neglected tropical diseases (NTDs) that are especially common among low-income populations in developing regions of Africa, Asia, and the Americas. Many natural products, particularly alkaloids, have been reported to have inhibitory activity against arginase, the key enzyme in the pathology caused by Leishmania sp. In this way, piperidine alkaloids (-)-cassine (1), (-)-spectaline (2), (-)-3-O-acetylcassine (3), and (-)-3-O-acetylspectaline (4) were isolated from Senna spectabilis flowers. These compounds (1/2 and 3/4) initially present as homologous mixtures were separated by high performance liquid chromatography and evaluated against the promastigote phase of Leishmania amazonensis. In addition, molecular docking simulations were implemented in order to probe the binding modes of the ligands 1-4 to the amino acids in the active site of L. amazonensis arginase. Alkaloid 2 (IC50 15.81 mu g mL(-1)) was the most effective against L. amazonensis. Compounds 2 and 4, with larger side chain, were more effective against the parasite than compounds 1 and 3. The cell viability test on Vero cells revealed that compound 2 (CC50 66.67 mu g mL-1) was the most toxic. The acetyl group in the 3-O position of the parent structures reduced the leishmanicidal activity and the toxicity of the alkaloids. Further, molecular docking suggested that Asn143 is essential for arginase to interact with (-)-spectaline-derived compounds, which agreed with the IC50 measurements. Our findings revealed that S. spectabilis is an important source of piperidine alkaloids with leishmanicidal activity. Moreover, the natural compound 3 has been isolated for the first time. Experimental investigation combined with theoretical study advances knowledge about the enzyme binding site mode of interaction and contributes to the design of new bioactive drugs against Leishmania infection.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 4418-26-2. Computed Properties of C8H7NaO4.

Recent Advances in the Synthesis of Piperidines: Functionalization of Preexisting Ring Systems

The present review focuses on strategies for the construction of piperidines which have appeared in the literature since 2003 through mid-2017. In a preceding chapter (201 /AFIE 191), we summarized synthetic methods involving the construction of the piperidine ring from essentially acyclic starting materials in an intra- or intermolecular manner. The present chapter aims at giving a general overview of decoration or modification of previously generated pyridines or piperidines. The hydrogenation of preformed pyridine or pyridinium rings and introduction of substituents into fully saturated piperidines as well as ring expansion of pyrrolidines to piperidines are the most prevalent methods.

Constructing micro-phase separation structure to improve the performance of anion-exchange membrane based on poly(aryl piperidinium) cross-linked membranes

The ether-bond-free poly(biphenyl piperidine)s are prepared to improve the alkaline stability of the anion exchange membrane (AEMs). At the same time, the construction of micro-phase separation structure is a good way to solve the trade-off’ problem between ionic conductivity and stability of AEMs. In this study, we report a new method for constructing micro-phase separation structures based on main-chain type AEMs and a crosslinking strategy that does not sacrifice ion exchange capacity. A series of poly(biphenyl piperidine)s AEMs (PAP-OH-x) are prepared by introducing 2-bromoethanol and 1,6-dibromohexane to form piperidine cationic groups and cross-linked structure. The structure of hydrophilic/hydrophobic phase separation is confirmed by TEM images. The cross-linked membrane of poly(biphenyl piperidine)s (PAP-OH-8%) membrane exhibits high conductivity of 0.081 S/cm with a rational water absorption (55.6%) and low swelling ratio (11.8%) at 80 degrees C, and also preserves the hydroxide conductivity (89.2% retention) after testing in a 5 M NaOH aqueous solution at 80 degrees C for 30 days, exhibits high alkaline stability. Furthermore, a single H-2/O-2 fuel cell with poly(biphenyl piperidine)s (PAP-OH-8%) membrane exhibits the open circuit voltage of 1.02 V and the peak power density of 290 mW/cm(2) at 60 degrees C.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 388077-74-5, you can contact me at any time and look forward to more communication. HPLC of Formula: C11H20N2O3.

Highly sensitive and wearable gas sensors consisting of chemically functionalized graphene oxide assembled on cotton yarn

Highly sensitive and wearable chemical sensors for the detection of toxic gas molecules are given significant attention for a variety of applications in human health care and environmental safety. Herein, we demonstrated fiber-type gas sensors based on graphene oxide functionalized with organic molecules such as heptafluorobutylamine (HFBA), 1-(2-methoxyphenyl) piperazine (MPP), and 4-(2-keto-1-benzimidazolinyl) piperidine (KBIP) by assembling functionalized graphene oxide (FGO) on a single yarn fabric. These gas sensors of FGO on yarn exhibited extraordinarily higher sensitivity upon exposure to gas molecules than chemically reduced graphene oxide due to many active functional groups on the GO surface. Furthermore, the mechanical stability and chemical durability of the resulting gas sensors are well-maintained. Based on these results, we expected that our sensors with high sensitive and wearability will provide a good premise for wearable chemical sensors-based multidisciplinary applications.

Improved Synthesis of N-Methylcadaverine

Alkaloids compose a large class of natural products, and mono-methylated polyamines are a common intermediate in their biosynthesis. In order to evaluate the role of selectively methylated natural products, synthetic strategies are needed to prepare them. Here, N-methylcadaverine is prepared in 37.3% yield in three steps. The alternative literature two-step strategy resulted in reductive deamination to give N-methylpiperidine as determined by the single crystal structure. A straightforward strategy to obtain the mono-alkylated aliphatic diamine, cadaverine, which avoids potential side-reactions, is demonstrated.

Development of Highly Efficient Organocatalytic Reaction toward Practical Total Synthesis of ent-Quinine

Recently, cinchona alkaloids such as quinine and quinidine were re-focused as next generation organocatalysts. Therefore, practical total syntheses of enantiomers of these alkaloids are required in current chemical society. Thus, efficient protocol for preparation of C4-alkyl substituted chiral piperidines using secondary amine catalyzed formal aza[3+3]cycloaddition reaction using aliphatic alpha,beta-unsaturated aldehydes and thiomalonamate derivatives were discovered as key step in total synthesis. In our reaction system, thiomalonamate is excellent nucleophile, and the addition of suitable acid and it’s amounts are important factor for the acceleration effect in organocatalytic reaction. These efforts lead to only 0.1 mol% catalyst loading in multi-gram scale synthesis for suitable reaction time.
