Sharma, Bhawana; Dutt, Vikas; Kaur, Nirmaljeet; Mittal, Ashwani; Dabur, Rajesh published the article 《Tinospora cordifolia protects from skeletal muscle atrophy by alleviating oxidative stress and inflammation induced by sciatic denervation》. Keywords: Tinospora skeletal muscle atrophy oxidative stress inflammation sciatic denervation; Histopathology; Inflammation; Oxidative stress; Sciatic denervation; Skeletal muscle atrophy; Tinospora cordifolia extract (TCE).They researched the compound: Piperidine-3-carboxylic acid( cas:498-95-3 ).Product Details of 498-95-3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:498-95-3) here.

Tinospora cordifolia (TC) is widely being used as immunomodulatory and re-juvenile drug and well described in Indian Ayurveda system of medicine. Rejuvenation also means the fine tuning of the skeletal muscles. Skeletal muscle related disorder, i.e. atrophy is major problem which arise due to cachexia, sarcopenia and immobilization. However, despite of the great efforts, there is scarcity of FDA approved drugs in the market to treat skeletal muscle atrophy. The current study was aimed to explore the in-vitro and in-vivo efficacy and mechanism of TC in myogenic differentiation and skeletal muscle atrophy to establish the possibility of its usage to counteract skeletal muscle atrophy. C2C12 cell lines were used to determine myogenic potential and anti-atrophic effects of T. cordifolia water extract (TCE). Its in-vitro efficacy was re-validated in vivo by supplementation of TCE at a dose of 200 mg/kg/p.o. for 30 days in denervated mice model of skeletal muscle atrophy. Effects of TCE administration on levels of oxidative stress, inflammatory markers and proteolysis were determined TCE supplementation displayed increased lymphocyte proliferation and induced myogenic differentiation of C2C12 myoblasts by significantly increasing myocytes length and thickness, in comparison to control (p < 0.05). TCE supplementation decreased oxidative stress and inflammatory response by significantly modulating activities of catalase, glutathione peroxidase, lipid peroxidase, superoxide dismutase and β-glucuronidase (p < 0.05). It increased MF-20c expression and ameliorated degradation of muscle protein by down-regulating MuRF-1 and calpain activity. TCE supplementation promotes myogenic differentiation in C2C12 cell lines and prevents denervation induced skeletal muscle atrophy by antagonizing the proteolytic systems (calpain and UPS) and maintaining the oxidative defense mechanism of the cell. Hence, TCE can be used as a protective agent against muscle atrophy. This literature about this compound(498-95-3)Product Details of 498-95-3has given us a lot of inspiration, and I hope that the research on this compound(Piperidine-3-carboxylic acid) can be further advanced. Maybe we can get more compounds in a similar way.

Recommanded Product: Piperidine-3-carboxylic acid. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Piperidine-3-carboxylic acid, is researched, Molecular C6H11NO2, CAS is 498-95-3, about Stereoselective Activity of 1-Propargyl-4-styrylpiperidine-like Analogues That Can Discriminate between Monoamine Oxidase Isoforms A and B. Author is Knez, Damijan; Colettis, Natalia; Iacovino, Luca G.; Sova, Matej; Pislar, Anja; Konc, Janez; Lesnik, Samo; Higgs, Josefina; Kamecki, Fabiola; Mangialavori, Irene; Dolsak, Ana; Zakelj, Simon; Trontelj, Jurij; Kos, Janko; Binda, Claudia; Marder, Mariel; Gobec, Stanislav.

The resurgence of interest in monoamine oxidases (MAOs) has been fueled by recent correlations of this enzymic activity with cardiovascular, neurol., and oncol. disorders. This has promoted increased research into selective MAO-A and MAO-B inhibitors. Here, we shed light on how selective inhibition of MAO-A and MAO-B can be achieved by geometric isomers of cis- and trans-1-propargyl-4-styrylpiperidines. While the cis isomers are potent human MAO-A inhibitors, the trans analogs selectively target only the MAO-B isoform. The inhibition was studied by kinetic anal., UV-vis spectrum measurements, and X-ray crystallog. The selective inhibition of the MAO-A and MAO-B isoforms was confirmed ex vivo in mouse brain homogenates, and addnl. in vivo studies in mice show the therapeutic potential of 1-propargyl-4-styrylpiperidines for central nervous system disorders. This study represents a unique case of stereoselective activity of cis/trans isomers that can discriminate between structurally related enzyme isoforms.

Application In Synthesis of Piperidine-3-carboxylic acid. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Piperidine-3-carboxylic acid, is researched, Molecular C6H11NO2, CAS is 498-95-3, about Adaptive Mechanisms of Baroreflectory Regulation of the Cardiovascular System in Extreme Hyperoxia. Author is Zhilyaev, S. Yu.; Platonova, T. F.; Alekseeva, O. S.; Nikitina, E. R.; Demchenko, I. T..

We hypothesized that all of these responses are components of the baroreflex that regulates blood pressure and circulation in hyperoxia. To test this hypothesis, we carried out experiments on awake rats in which the dynamics of arterial blood pressure, organ blood flow (brain, kidney, lower limbs) and ECG was tracked in response to oxygen breathing at 1, 3 and 5 ATA. The afferent and efferent baroreflex pathways were studied using denervation of the carotid baroreceptors and transection of the aortic depressor nerves and vagus nerve. The baroreflex effectiveness was assessed using phenylephrine injections or spontaneous changes in blood pressure. To activate the GABAergic system, nipecotic acid was injected into the lateral ventricle of the brain. Bradycardia and a decrease in cardiac output, resulting from baroreflex activation by hyperoxia, are actualized via efferent sympathetic and parasympathetic pathways. At 1 and 3 ATA the baroreflex effectiveness increased compared to atm. air breathing, but extreme hyperoxia (5 ATA) suppressed the baroreflex mechanism. Activation of the GABAergic system in the cerebral cortex by nipecotic acid prevented the loss of the hyperoxic baroreflex. In hyperoxia, the baroreflex mechanism realizes adaptive responses of the cardiovascular system aimed at restraining the delivery of excess oxygen to an organism and mitigates activation of the sympathetic nervous system.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Piperidine-3-carboxylic acid( cas:498-95-3 ) is researched.Recommanded Product: 498-95-3.Buran, Kerem; Reis, Rengin; Sipahi, Hande; Oenen Bayram, F. Esra published the article 《Piperazine and piperidine-substituted 7-hydroxy coumarins for the development of anti-inflammatory agents》 about this compound( cas:498-95-3 ) in Archiv der Pharmazie (Weinheim, Germany). Keywords: piperazine piperidine antiinflammatory agent; anti-inflammatory activity; coumarin; nitrite reduction; piperazine; piperidine. Let’s learn more about this compound (cas:498-95-3).

Coumarins (2H-1-benzopyran-2-one), derivatives that can be isolated from several plants, have been reported for their anticoagulant, antimicrobial, anti-inflammatory, or anticancer activity. Some of these structures are currently approved for the treatment of cardiovascular diseases, as antibiotics or as an anticancer drug. Given the great potential of this structure and the limited number of studies that focus on mols. derived from carbon 8 of the benzopyranone heterocycle, we synthesized in this project 38 coumarin derivatives by substituting carbon 8 of the benzopyran ring with some aromatic and aliphatically substituted piperidines and piperazines. As a few of these structures were already shown to exhibit some carbonic anhydrase (CA) inhibition and as CA enzymes are reported to be closely related to inflammation, the synthesized derivatives were evaluated for their anti-inflammatory activity in vitro. The results indicated that compounds 20 and 31 revealed promising anti-inflammatory activity, as they demonstrated better activity than the reference drugs.

Compound: Piperidine-3-carboxylic acid, is researched, Molecular C6H11NO2, CAS is 498-95-3, about Noncanonical transmission of a measles virus vaccine strain from neurons to astrocytes.

Viruses, including members of the herpes-, entero-, and morbillivirus families, are the most common cause of infectious encephalitis in mammals worldwide. During most instances of acute viral encephalitis, neurons are typically the initial cell type that is infected. However, as replication and spread ensue, other parenchymal cells can become viral targets, especially in chronic infections. Consequently, to ascertain how neurotropic viruses trigger neuropathol., it is crucial to identify which central nervous system (CNS) cell populations are susceptible and permissive throughout the course of infection, and to define how viruses spread between distinct cell types. Using a measles virus (MV) transgenic mouse model that expresses human CD46 (hCD46), the MV vaccine strain receptor, under the control of a neuron-specific enolase promoter (NSE-hCD46+ mice), a novel mode of viral spread between neurons and astrocytes was identified. Although hCD46 is required for initial neuronal infection, it is dispensable for heterotypic spread to astrocytes, which instead depends on glutamate transporters and direct neuron-astrocyte contact. Moreover, in the presence of RNase A, astrocyte infection is reduced, suggesting that nonenveloped ribonucleoproteins (RNP) may cross the neuron-astrocyte synaptic cleft. The characterization of this novel mode of intercellular transport offers insights into the unique interaction of neurons and glia and may reveal therapeutic targets to mitigate the life-threatening consequences of measles encephalitis.
