Deconstructive diversification of cyclic amines

Deconstructive functionalization involves carbon-carbon (C-C) bond cleavage followed by bond construction on one or more of the constituent carbons. For example, ozonolysis(1) and olefin metathesis(2,3) have allowed each carbon in C=C double bonds to be viewed as a functional group. Despite the substantial advances in deconstructive functionalization involving the scission of C=C double bonds, there are very few methods that achieve C(sp(3))-C(sp(3)) single-bond cleavage and functionalization, especially in relatively unstrained cyclic systems. Here we report a deconstructive strategy to transform saturated nitrogen heterocycles such as piperidines and pyrrolidines, which are important moieties in bioactive molecules, into halogen-containing acyclic amine derivatives through sequential C(sp(3))-N and C(sp(3))-C(sp(3)) single-bond cleavage followed by C(sp(3))-halogen bond formation. The resulting acyclic haloamines are versatile intermediates that can be transformed into various structural motifs through substitution reactions. In this way we achieve the skeletal remodelling of cyclic amines, an example of scaffold hopping. We demonstrate this deconstructive strategy by the late-stage diversification of proline-containing peptides.

Iron and Physical Activity: Bioavailability Enhancers, Properties of Black Pepper (Bioperine(R)) and Potential Applications

Black pepper (Piper nigrumL.) has been employed in medicine (epilepsy, headaches, and diabetes), where its effects are mainly attributed to a nitrogen alkaloid called piperidine (1-(1-[1,3-benzodioxol-5-yl]-1-oxo-2,4 pentenyl) piperidine). Piperine co-administered with vitamins and minerals has improved its absorption. Therefore, this study aimed to describe the impact of the joint administration of iron (Fe) plus black pepper in physically active healthy individuals. Fe is a micronutrient that aids athletic performance by influencing the physiological functions involved in endurance sports by improving the transport, storage, and utilization of oxygen. Consequently, athletes have risk factors for Fe depletion, Fe deficiency, and eventually, anemia, mainly from mechanical hemolysis, gastrointestinal disturbances, and loss of Fe through excessive sweating. Declines in Fe stores have been reported to negatively alter physical capacities such as aerobic capacity, strength, and skeletal muscle recovery in elite athletes. Thus, there is a need to maintain Fe storage, even if Fe intake meets the recommended daily allowance (RDA), and Fe supplementation may be justified in physically active individuals, in states of Fe deficiency, with or without anemia. Females, in particular, should monitor their Fe hematological profile. The recommended oral Fe supplements are ferrous or ferric salts, sulfate, fumarate, and gluconate. These preparations constitute the first line of treatment; however, the high doses administered have gastrointestinal side effects that reduce tolerance and adherence to treatment. Thus, a strategy to counteract these adverse effects is to improve the bioavailability of Fe. Therefore, piperine may benefit the absorption of Fe through its bioavailability enhancement properties. Three research studies of Fe associated with black pepper have reported improvements in parameters related to the metabolism of Fe, without adverse effects. Although more research is needed, this could represent an advance in oral Fe supplementation for physically active individuals.

Metal-free nitrogen-doped graphenic materials as cathode catalysts for the oxygen reduction reaction in polymer electrolyte membrane fuel cells

Exhibiting a very high surface area, a good electrical conductivity and a high density of active sites, nitrogen-doped graphenic materials are considered as promising catalysts for the oxygen reduction reaction (ORR). Seldom studied in acidic media, N-doped graphenic foams were tested here as the cathode catalysts of a polymer electrolyte membrane fuel cell (PEMFC). The materials were prepared via a solvothermal-based process, by reacting either cyclohexanol and ethanolamine or 1-(2-hydroxyethylethyl) piperidine with metallic sodium, under high pressure and temperature. Membrane electrode assemblies were prepared with a Pt/C anode, 212 Nafion membrane, and an 8 mm disk cathode based on the graphenic materials. The performance exhibited by the PEMFC was evaluated using chronopotentiometry and impedance spectroscopy, depending on the synthesis conditions. The kinetic parameters of the ORR were estimated by interpretation of the experimental data: the high Tafel slope found might express the partial control of oxygen diffusion through the graphenic microporous structure. Relationships between the electrochemical behavior of the materials and their structural properties are discussed. Moderately crystallized materials with a low oxygen content showed the highest catalytic properties, with a current density larger than 30 mA cm(-2) and a maximum power density at 2.3 mW cm(-2).

Construction of ion conducting channels by embedding hydrophilic oligomers in piperidine functionalized poly(2, 6-dimethyl-1, 4-phenylene oxide) membranes

A suitable microphase separation morphology has been demonstrated to be an efficient strategy to achieve high ionic conductivity with reasonable durability to anion exchange membranes (AEMs). Herein, hydrophilic oligomers of polyethylene glycols (PEGs) with different molecular weights were blended, separately, with poly(2,6-dimethyl-1,4-phenylene oxide) modified by 4,4-diethoxybutan-1 -amine and 1-methylpiperidine (20PDM). The presence of hydrophilic PEGs facilitates the formation of the interconnected nano-channels in the AEMs for ion conduction according to the analysis results by both transmission electron microscopy (TEM) and small angle Xray scattering (SAXS). The membrane containing 2 wt% PEGs with a molecular weight of 2 kDa reaches a hydroxide conductivity of 97.2 mS cm(-1) at 80 degrees C, which is 25 mS cm(-1) higher than that the pristine 20PDM membrane possessing the same ion exchange capacity. A peak power density of 328 mW cm(-2) is attained at 60 degrees C by the proposed membrane based single fuel cell fueling with humidified H-2 and O-2 with 0.1 MPa of back pressure. The chemical structure, water uptake and swelling as well as resistance to hot alkali solutions of the prepared membranes were investigated.

Benzyne-Induced Ring Opening Reactions of DABCO: Synthesis of 1,4-Disubstituted Piperazines and Piperidines

The 2-(4-phenylpiperazin-1-yl)ethan-1-amine scaffold is a structurally important motif that occurs frequently in medicinal and pharmaceutical chemistry. Despite the significance of this moiety, general strategies for its synthesis to date have required multistep methods and have been very limited, such as the use of SNAr-type reactions. Herein, we describe a synthetic methodology employing benzynes, 1,4-diazabicyclo(2.2.2)octane (DABCO), and nitrogen nucleophiles to access these privileged organic compounds. The established protocol proved to be a transition-metal-free, mild reaction that proceeded via a quaternary ammonium salt formed from the benzyne and DABCO.

Greener and practical synthesis of 4,4 ‘-(arylmethylene)bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s through a conventional heating and a mechanochemical procedure

A new catalytic application of 4,4 ‘-trimethylenedipiperidine for the efficient synthesis of 4,4 ‘-(arylmethylene)bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s is developed. According to the principles of green chemistry, the reaction was performed by conventional and non-conventional processes: (a) in the refluxing ethanol using a catalytic amount of organocatalyst; (b) at room temperature in the presence of organocatalyst in a planetary ball mill under solvent-free conditions. The organocatalyst could be reused up to 10 runs, and a negligible reduction of catalytic activity was detected. A variety of substituted 4,4 ‘-(arylmethylene)bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s were obtained in good-to-excellent yields under eco-friendly conditions. 4,4 ‘-Trimethylenedipiperidine is commercially available and easy to handle and storage, less toxic, non-flammable, as well as it shows high thermal stability and good solubility in water. The current methodology has merits including (a) wide substrate-scope and high yields of the desired products in the short reaction times, (b) avoiding the use of hazardous solvents and acidic and metal-containing catalysts, (c) minimize the generation of hazardous waste, and (d) simple workup process. Based on great potential as a promising organocatalyst, we hope it can be used as a greener alternative to piperidine for other organic transformations.

Discovery of Amoebicidal Compounds by Combining Computational and Experimental Approaches

Pathogenic and opportunistic free-living amoebae such as Acanthamoeba spp. can cause keratitis (Acanthamoeba keratitis [AK]), which may ultimately lead to permanent visual impairment or blindness. Acanthamoeba can also cause rare but usually fatal granulomatous amoebic encephalitis (GAE). Current therapeutic options for AK require a lengthy treatment with nonspecific drugs that are often associated with adverse effects. Recent developments in the field led us to target cAMP pathways, specifically phosphodiesterase. Guided by computational tools, we targeted the Acanthamoeba phosphodiesterase RegA. Computational studies led to the construction and validation of a homology model followed by a virtual screening protocol guided by induced-fit docking and chemical scaffold analysis using our medicinal and biological chemistry (MBC) chemical library. Subsequently, 18 virtual screening hits were prioritized for further testing in vitro against Acanthamoeba castellanii, identifying amoebicidal hits containing piperidine and urea imidazole cores. Promising activities were confirmed in the resistant cyst form of the amoeba and in additional clinical Acanthamoeba strains, increasing their therapeutic potential. Mechanism-of-action studies revealed that these compounds produce apoptosis through reactive oxygen species (ROS)-mediated mitochondrial damage. These chemical families show promise for further optimization to produce effective antiacanthamoebal drugs.

Bisubstrate inhibitors of 6-hydroxymethyl-7,8-dihydropterin pyrophosphokinase: Transition state analogs for high affinity binding

6-Hydroxymethyl-7,8-dihydropterin pyrophosphokinase (HPPK) is a key enzyme in the folate biosynthesis pathway. It catalyzes pyrophosphoryl transfer from ATP to 6-hydroxymethyl-7,8-dihydropterin (HP). HPPK is essential for microorganisms but absent in mammals; therefore, it is an attractive target for developing novel antimicrobial agents. Previously, based on our studies of the structure and mechanism of HPPK, we created first-generation bisubstrate inhibitors by linking 6-hydroxymethylpterin to adenosine through phosphate groups, and developed second-generation inhibitors by replacing the phosphate bridge with a linkage that contains a piperidine moiety. Here, we report third-generation inhibitors designed based on the piperidine-containing inhibitor, mimicking the transition state. We synthesized two such inhibitors, characterized their protein-binding and enzyme inhibition properties, and determined their crystal structures in complex with HPPK, advancing the development of such bisubstrate analog inhibitors.

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 22990-77-8. HPLC of Formula: C6H14N2.

In silico evaluation and in vitro growth inhibition of Plasmodium falciparum by natural amides and synthetic analogs

Malaria, caused by protozoa of the genus Plasmodium, is a disease that infects hundreds of millions of people annually, causing an enormous social burden in many developing countries. Since current antimalarial drugs are starting to face resistance by the parasite, the development of new therapeutic options has been prompted. The enzyme Plasmodium falciparum enoyl-ACP reductase (PfENR) has a determinant role in the fatty acid biosynthesis of this parasite and is absent in humans, making it an ideal target for new antimalarial drugs. In this sense, the present study aimed at evaluating the in silico binding affinity of natural and synthetic amides through molecular docking, in addition to their in vitro activity against P. falciparum by means of the SYBR Green Fluorescence Assay. The in vitro results revealed that the natural amide piplartine (1a) presented partial antiplasmodial activity (20.54 mu M), whereas its synthetic derivatives (1m-IC50 104.45 mu M), (1b, 1g, 1k, and 14f) and the natural amide piperine (18a) were shown to be inactive (IC50 > 200 mu M). The in silico physicochemical analyses demonstrated that compounds 1m and 14f violated the Lipinski’s rule of five. The in silico analyses showed that 14f presented the best binding affinity (- 13.047 kcal/mol) to PfENR and was also superior to the reference inhibitor triclosan (- 7.806 kcal/mol). In conclusion, we found that the structural modifications in 1a caused a significant decrease in antiplasmodial activity. Therefore, new modifications are encouraged in order to improve the activity observed.

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 22990-77-8 help many people in the next few years. SDS of cas: 22990-77-8.
