The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Revised Pharmacophore Model for 5-HT2A Receptor Antagonists Derived from the Atypical Antipsychotic Agent Risperidone》. Authors are Shah, Urjita H.; Gaitonde, Supriya A.; Moreno, Jose L.; Glennon, Richard A.; Dukat, Malgorzata; Gonzalez-Maeso, Javier.The article about the compound:Piperidine-3-carboxylic acidcas:498-95-3,SMILESS:O=C(C1CNCCC1)O).Name: Piperidine-3-carboxylic acid. Through the article, more information about this compound (cas:498-95-3) is conveyed.

Pharmacophore models for 5-HT2A receptor antagonists consist of two aromatic/hydrophobic regions at a given distance from a basic amine. We have previously shown that both aromatic/hydrophobic moieties are unnecessary for binding or antagonist action. Here, we deconstructed the 5-HT2A receptor antagonist/serotonin-dopamine antipsychotic agent risperidone into smaller structural segments that were tested for 5-HT2A receptor affinity and function. We show, again, that the entire risperidone structure is unnecessary for retention of affinity or antagonist action. Replacement of the 6-fluoro-3-(4-piperidinyl)-1,2-benz[d]isoxazole moiety by isosteric tryptamines resulted in retention of affinity and antagonist action. Addnl., 3-(4-piperidinyl)-1,2-benz[d]isoxazole (10), which represents less than half the structural features of risperidone, retains both affinity and antagonist actions. 5-HT2A receptor homol. modeling/docking studies suggest that 10 binds in a manner similar to risperidone and that there is a large cavity to accept various N4-substituted analogs of 10 such as risperidone and related agents. Alterations of this “”extended”” moiety improve receptor binding and functional potency. We propose a new risperidone-based pharmacophore for 5-HT2A receptor antagonist action.

Copper-catalyzed oxidative cross-coupling of benzylic C-H bonds with alcs. to afford benzyl ethers, enabled by a redox buffering strategy that maintains the activity of the copper catalyst throughout the reaction was reported. The reactions employ the C-H substrate as the limiting reagent and exhibit broad scope with respect to both coupling partners. This approach to direct site-selective functionalization of C(sp3)-H bonds provides the basis for efficient three-dimensional diversification of organic mols. and should find widespread utility in organic synthesis, particularly for medicinal chem. applications.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Piperidine-3-carboxylic acid, is researched, Molecular C6H11NO2, CAS is 498-95-3, about Microglial expression of GAT-1 in the cerebral cortex..Related Products of 498-95-3.

Microglial cells are the immune cells of the brain that, by sensing the microenvironment, permit a correct brain development and function. They communicate with other glial cells and with neurons, releasing and responding to a number of molecules that exert effects on surrounding cells. Among these, neurotransmitters and, in particular, gamma-aminobutyric acid (GABA) has recently gained interest in this context. We demonstrated the expression of GABA transporter 1 (GAT-1) in microglial cells both in soma and cell processes. We show that microglial cell treatment with 1,2,5,6-tetrahydro-1-[2-[[(diphenylmethylene)amino]oxy]ethyl]-3-pyridinecarboxylic acid hydrochloride (NNC-711), a potent and selective GAT-1 inhibitor, significantly reduced Na+ -dependent GABA uptake. On the other hand, GABA uptake was significantly increased by cell treatment with (S)-1-[2-[tris(4-methoxyphenyl)methoxy]ethyl]-3-piperidinecarboxylic acid (SNAP-5114), a GAT-2/3 inhibitor, and this effect was completely blocked by the botulinum toxin BoNT/C1, that specifically cleaves and inactives syntaxin 1A (STX1A). Overall, these findings show that microglial cells express GAT-1 and indicate that STX1A plays an important role in the regulation of GAT-1-dependent GABA uptake in microglia.

Compound: 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol( cas:35836-73-8 ) is researched.Product Details of 35836-73-8.Graham, Brian J.; Windsor, Ian W.; Gold, Brian; Raines, Ronald T. published the article 《Boronic acid with high oxidative stability and utility in biological contexts》 about this compound( cas:35836-73-8 ) in ChemRxiv. Keywords: boronic acid oxidative stability crystal structure pharmacophore. Let’s learn more about this compound (cas:35836-73-8).

Despite their desirable attributes, boronic acids have had a minimal impact in biol. contexts. A significant problem has been their oxidative instability. At physiol. pH, phenylboronic acid and its boronate esters are oxidized by reactive oxygen species at rates comparable to those of thiols. After considering the mechanism and kinetics of the oxidation reaction, we reasoned that diminishing electron d. on boron could enhance oxidative stability. We found that a boralactone, in which a carboxyl group serves as an intramol. ligand for the boron, increases stability by 104-fold. Computational analyses revealed that the resistance to oxidation arises from diminished stabilization of the p orbital of boron that develops in the rate-limiting transition state of the oxidation reaction. Like simple boronic acids and boronate esters, a boralactone binds covalently and reversibly to 1,2-diols, such as those in saccharides. The kinetic stability of its complexes is, however, at least 20-fold greater. A boralactone also binds covalently to a serine side chain in a protein. These attributes confer unprecedented utility upon boralactones in the realms of chem. biol. and medicinal chem.
