And the article was included in Chemistry & Biodiversity in 2013.Safety of (S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid The following contents are mentioned in the article:

The efrapeptins, a family of naturally occurring peptides with inhibitory activities against ATPases, contain several 伪,伪-disubstituted 伪-amino acids such as 伪-aminoisobutyric acid (Aib) or isovaline (Iva) besides pipecolic acid (Pip), 尾-Ala, Leu, Gly, and a C-terminal heterocyclic residue. Secondary 伪-amino acids such as proline are known to stabilize discrete conformations in peptides. A similar influence is ascribed to N-alkyl 伪-amino acids. We synthesized two efrapeptin C analogs with replacement of Pip by N-methyl-L-alanine (MeAla) using a combination of solid- and solution-phase techniques in a fragment-condensation strategy to compare the conformational bias of both secondary amino acids. The solution conformation was investigated by vibrational CD (VCD) to probe whether the analogs adopt a 3₁₀-helical conformation. The MeAla-containing analogs [MeAla^1,3]efrapeptin C and [MeAla^1,3,11]efrapeptin C inhibit ATP hydrolysis by the A₃B₃ complex of A₁A₀-ATP synthase from Methanosarcina mazei Goe1.

A Supervised Molecular Dynamics Approach to Unbiased Ligand-Protein Unbinding was written by Deganutti, Giuseppe;Moro, Stefano;Reynolds, Christopher A.. And the article was included in Journal of Chemical Information and Modeling in 2020.Application of 1222780-33-7 The following contents are mentioned in the article:

The recent paradigm shift toward the use of the kinetics parameters in place of thermodn. constants is leading the computational chem. community to develop methods for studying the mechanisms of drug binding and unbinding. From this standpoint, mol. dynamics (MD) plays an important role in delivering insight at the mol. scale. However, a known limitation of MD is that the time scales are usually far from those involved in ligand-receptor unbinding events. Here, we show that the algorithm behind supervised MD (SuMD) can simulate the dissociation mechanism of druglike small mols. while avoiding the input of any energy bias to facilitate the transition. SuMD was tested on seven different intermol. complexes, covering four G protein-coupled receptors: the A_2A and A₁ adenosine receptors, the orexin 2 and the muscarinic 2 receptors, and the soluble globular enzyme epoxide hydrolase. SuMD well-described the multi-step nature of ligand-receptor dissociation, rationalized previous exptl. data and produced valuable working hypotheses for structure-kinetics relationships. This study involved multiple reactions and reactants, such as 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7Application of 1222780-33-7).

Probing the orientation of inhibitor and epoxy-eicosatrienoic acid binding in the active site of soluble epoxide hydrolase was written by Lee, Kin Sing Stephen;Henriksen, Niel M.;Ng, Connie J.;Yang, Jun;Jia, Weitao;Morisseau, Christophe;Andaya, Armann;Gilson, Michael K.;Hammock, Bruce D.. And the article was included in Archives of Biochemistry and Biophysics in 2017.Product Details of 1222780-33-7 The following contents are mentioned in the article:

Soluble epoxide hydrolase (sEH) is an important therapeutic target of many diseases, such as chronic obstructive pulmonary disease (COPD) and diabetic neuropathic pain. It acts by hydrolyzing and thus regulating specific bioactive long chain polyunsaturated fatty acid epoxides (lcPUFA), like epoxyeicosatrienoic acids (EETs). To better predict which epoxides could be hydrolyzed by sEH, one needs to dissect the important factors and structural requirements that govern the binding of the substrates to sEH. This knowledge allows further exploration of the physiol. role played by sEH. Unfortunately, a crystal structure of sEH with a substrate bound has not yet been reported. In this report, new photoaffinity mimics of a sEH inhibitor and EET regioisomers were prepared and used in combination with peptide sequencing and computational modeling, to identify the binding orientation of different regioisomers and enantiomers of EETs into the catalytic cavity of sEH. Results indicate that the stereochem. of the epoxide plays a crucial role in dictating the binding orientation of the substrate. This study involved multiple reactions and reactants, such as 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7Product Details of 1222780-33-7).

Soluble epoxide hydrolase inhibitor promotes immunomodulation to inhibit bone resorption was written by Napimoga, M. H.;Rocha, E. P.;Trindade-da-Silva, C. A.;Demasi, A. P. D.;Martinez, E.

In the current study we used the sEH inhibitor (1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea [TPPU]) to investigate the immunomodulatory effects in a mouse periodontitis model. Mice were infected on days 0, 2, and 4 with Aggregatibacter actinomycetemcomitans and divided into groups (n = 6) that were treated orally, daily for 15 days, with 1 mg/kg of TPPU. Then, the mice were killed and their jaws were analyzed for bone resorption using morphometry. Immunoinflammatory markers in the gingival tissue were analyzed by microarray PCR or western blotting. Infected mice treated with TPPU showed lower bone resorption than infected mice without treatment. Interestingly, infected mice showed increased expression of sEH; however, mice treated with TPPU had a reduction in expression of sEH. Besides, several proinflammatory cytokines and mol. markers were downregulated in the gingival tissue in the group treated with 1 mg/kg of TPPU. The sEH inhibitor, TPPU, showed immunomodulatory effects, decreasing bone resorption and inflammatory responses in a bone resorption mouse model.

And the article was included in Journal of Medicinal Chemistry in 2004.Recommanded Product: 86069-86-5 The following contents are mentioned in the article:

Inhibitor of apoptosis (IAP) proteins are overexpressed in many cancers and have been implicated in tumor growth, pathogenesis, and resistance to chemo- or radiotherapy. On the basis of the NMR structure of a SMAC peptide complexed with the BIR3 domain of X-linked IAP (XIAP), a novel series of XIAP antagonists was discovered. The most potent compounds in this series bind to the baculovirus IAP repeat 3 (BIR3) domain of XIAP with single-digit nanomolar affinity and promote cell death in several human cancer cell lines. In a MDA-MB-231 breast cancer mouse xenograft model, these XIAP antagonists inhibited the growth of tumors. Close structural analogs that showed only weak binding to the XIAP-BIR3 domain were inactive in the cellular assays and showed only marginal in vivo activity. Our results are consistent with a mechanism in which ligands for the BIR3 domain of XIAP induce apoptosis by freeing up caspases. The present study validates the BIR3 domain of XIAP as a target and supports the use of small mol. XIAP antagonists as a potential therapy for cancers that overexpress XIAP. This study involved multiple reactions and reactants, such as (S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid (cas: 86069-86-5Recommanded Product: 86069-86-5).

Cancer therapy reduces tumor burden via tumor cell death (debris), which can accelerate tumor progression via the failure of inflammation resolution Thus, there is an urgent need to develop treatment modalities that stimulate the clearance or resolution of inflammation-associated debris. Here, we demonstrate that chemotherapy-generated debris stimulates metastasis by up-regulating soluble epoxide hydrolase (sEH) and the prostaglandin E2 receptor 4 (EP4). Therapy-induced tumor cell debris triggers a storm of proinflammatory and proangiogenic eicosanoid-driven cytokines. Thus, targeting a single eicosanoid or cytokine is unlikely to prevent chemotherapy-induced metastasis. Pharmacol. abrogation of both sEH and EP4 eicosanoid pathways prevents hepato-pancreatic tumor growth and liver metastasis by promoting macrophage phagocytosis of debris and counterregulating a protumorigenic eicosanoid and cytokine storm. Therefore, stimulating the clearance of tumor cell debris via combined sEH and EP4 inhibition is an approach to prevent debris-stimulated metastasis and tumor growth.
