A novel piperidine identified by stem cell-based screening attenuates pulmonary arterial hypertension by regulating BMP2 and PTGS2 levels

Genetic defects in bone morphogenetic protein type II receptor (BMPRII) signalling and inflammation contribute to the pathogenesis of pulmonary arterial hypertension (PAH). The receptor is activated by bone morphogenetic protein (BMP) ligands, which also enhance BMPR2 transcription. A small-molecule BMP upregulator with selectivity on vascular endothelium would be a desirable therapeutic intervention for PAH. We assayed compounds identified in the screening of BMP2 upregulators for their ability to increase the expression of inhibitor of DNA binding 1 (Id1), using a dual reporter driven specifically in human embryonic stem cell-derived endothelial cells. These assays identified a novel piperidine, BMP upregulator 1 (BUR1), that increased endothelial Idl expression with a half-maximal effective concentration of 0.098 mu mol.L-1. Microarray analyses and immunoblotting showed that BUR1 induced BMP2 and prostaglandin-endoperoxide synthase 2 (PTGS2) expression. BUR1 effectively rescued deficient angiogenesis in autologous BMPR2(+/R899X) endothelial cells generated by CRISPR/Cas9 and patient cells. BUR1 prevented and reversed PAH in monocrotaline rats, and restored BMPRII downstream signalling and modulated the arachidonic acid pathway in the pulmonary arterial endothelium in the Sugen 5416/hypoxia PAH mouse model. In conclusion, using stem cell technology we have provided a novel small-molecule compound which regulates BMP2 and PTGS2 levels that might be useful for the treatment of PAH.

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 3040-44-6 is helpful to your research. Formula: C7H15NO.

Molecular insights into the hydrodenitrogenation mechanism of pyridine over Pt/gamma-Al2O3 catalysts

The hydrodenitrogenation of nitrogen-containing heterocycles over noble metals has fundamental importance for energy and environmental science. To develop more efficient catalyst, mechanistic investigation has been conducted with a method combining in situ Fourier transformation infrared experiments and density functional theory calculations in this work. The in situ experiments indicate flatly adsorbed pyridine molecules convert to pyridinium and alpha-pyridyl species at higher temperature on metallic Pt of Pt/gamma-Al2O3 catalysts. Pyridine hydrogenation distinctly takes place at 150 degrees C with the appearance of methylene stretching vibrations, and a stepwise mechanism is identified as the temperature further increases. The adsorption, hydrogenation and hydrogenolysis of pyridine on Pt are studied in detail by theoretical calculations. In line with these findings, the geometry optimization confirms pyridine preferentially adsorbs on Pt(111) and Pt(211) both in a parallel configuration. Based on the Langmuir-Hinshelwood mechanism, the results show successive hydrogenation markedly lowers the energy barrier for subsequent hydrogenolysis. The C-N bond cleavage occurs via nucleophilic attack of pentahydropyridine, rather than piperidine, which determines the reaction products, including piperidine, n-pentylamine and n-pentane. The comparative study reveals both hydrogenation and hydrogenolysis are kinetically and thermodynamically more competitive on Pt(211) than Pt(111). Especially for hydrogenolysis, the coordinatively unsaturated Pt step atoms play an essential role in C-N bond cleavage. Thus, hydrogenolysis is more geometric-dependent than hydrogenation. This provides instructive information for the design of catalysts with adjustable product selectivity.

Synthetic Route of 106-52-5, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 106-52-5 is helpful to your research.

1-[2-(Adamantan-1-yl)-2-hydroxyethyl]-1,2,3,6-tetrahydropyridines were obtained by reduction of 1-[(adamantan-1-yl)-2-oxoethyl]-pyridinium bromides. By the action of trifluoromethanesulfonic acid, they undergo carbocationic intramolecular cyclization accompanied by the Wagner-Meerwein rearrangement with the formation of substituted 1-azabicyclo[3.3.1]non-3-enes annulated with the homoadamantane framework.

Theoretical Study of the Borono-Mannich Reaction with Pinacol Allenylboronate

A density functional theory study of the mechanism of the Borono-Mannich reaction using benzylamine and piperidine as representative examples of primary and secondary amines with pinacol allenylboronate is presented. The study shows that both reactions progress through coordination between the boron and the phenolic oxygen. Ring size strain and hydrogen bond activation appear to determine the observed divergent regioselectivity. In the case of benzylamine, the eight-membered ring transition structure that leads to the propargylamine exhibits a hydrogen bond between the hydrogen attached to the nitrogen and the phenolic oxygen (gamma-attack), whereas for piperidine a hydrogen bond between the hydrogen on the imine carbon and one of the oxygens of the pinacol group was observed in the six-membered ring transition structure toward the allenylamine (alpha-attack).

Flexibility of small molecular CD4 mimics as HIV entry inhibitors

CD4 mimics such as YIR-821 and its derivatives are small molecules which inhibit the interaction between the Phe43 cavity of HIV-1 gp120 with host CD4, an interaction that is involved in the entry of HIV to cells. Known CD4 mimics generally possess three structural features, an aromatic ring, an oxalamide linker and a piperidine moiety. We have shown previously that introduction of a cyclohexyl group and a guanidine group into the piperidine moiety and a fluorine atom at the meta-position of the aromatic ring leads to a significant increase in the anti-HIV activity. In the current study, the effects of conformational flexibility were investigated by introduction of an indole-type group in the junction between the oxalamide linker and the aromatic moiety or by replacement of the oxalamide linker with a glycine linker. This led to the development of compounds with high anti-HIV activity, showing the importance of the junction region for the expression of high anti-HIV activity. The present data are expected to be useful in the future design of novel CD4 mimic molecules.

Synthesis of Diastereomeric Pyrrolidine Sulfamides via Anchimerically Assisted Nucleophilic Substitution Reactions

The Mitsunobu reaction was employed in a key step during the development of a convenient synthetic route for the enantioselective preparation of pyrrolidine-sulfamide ligands from (R)-or (S)- [(S)-1-benzylpyrrolidin-2-yl](phenyl) methanol, and employing tert-butyl pyrrolidin-1-yl-sulfonylcarbamate as a non-conventional nucleophilic source. Although it is well documented that the exposure of this type of diastereomeric amino alcohols to the above-mentioned nucleophile usually leads to the formation of piperidines via ring expansion, either through classical nucleophilic substitution or the Mitsunobu version, only the pyrrolidine derivatives were generated with retention of configuration on the exocyclic stereocenter, owing to the neighboring group participation (internal backside nucleophilic substitution, S(N)ib). Final removal of the N-Boc protecting group from the sulfamide fragment afforded chiral compounds with significant potential as chiral ligands in asymmetric catalysis.

Synthesis of tetrafluorinated piperidines from nitrones via a visible-light-promoted annelation reaction

A method for the one-step construction of 3,3,4,4-tetrafluorinated piperidines from nitrones and readily accessible tetrafluorinated iodobromobutane is described. The reaction requires an excess amount of ascorbic acid as the terminal reductant and is performed in the presence of an iridium photocatalyst activated by blue light. The annelation is a result of a radical addition at the nitrone, intramolecular nucleophilic substitution, and reduction of the N-O bond.
